BG2 Opcodes


#0 (0x0) Stat: AC vs. Damage Type Modifier Variants: IWD2
Parameter #1: AC Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the AC Modifier field to the category specified by the Type field.

Known values for Type are:
  • 0 ⟶ All
  • 1 ⟶ Crushing
  • 2 ⟶ Missile
  • 4 ⟶ Piercing
  • 8 ⟶ Slashing
  • 16 ⟶ Base AC setting
    • Sets the targets AC to the value specified by the AC Modifier field. If the targets AC is already AC Modifier or below, this effect will do nothing.

Each modifier type to AC from this opcode is capped to the range [-20,20]. Each AC type total is capped to the range [-32768,32767].

Note: IWD1 and PST use a slightly different version. The “Base AC” sets to field - 1 instead.
IWD2 uses different parameters altogether.
Note:

#1 (0x1) Stat: Attacks Per Round Modifier Variants: BGEE
Parameter #1: Key Modifier
Parameter #2: Type
Description:
Alters a characters Attacks per Round, by changing the Key by the modifier value specified by the 'Key Value' field, in the style specified by 'Type' field.
Key Attacks per Round
0 0
1 1
2 2
3 3
4 4
5 5
6 0.5
7 1.5
8 2.5
9 3.5
10 4.5


Known values for 'Type' are:
0 Cumulative Modifier -> Key = Key + 'Key Modifier' value
1 Flat Value Modifier -> Key = 'Key Modifier' value
2 Percentage Modifier -> Key = (Key * 'Key Modifier' value) / 100
3 Cumulative Modifier -> Same as 0
Info: When this opcode is stacked, the values of the Key Modifier are stacked, not the number of attacks.
Note: IWD1 treats all keys above 5 as 5. PST does not support Type 3, while BG(2)EE uses it differently.
Important: Timing Modes 1/4/7 alters the creature's base APR stat, leaving behind no removable effect.

#2 (0x2) Cure: Sleep
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Removes opcode #39 effects and the STATE_SLEEPING flag from the targeted creature(s).
This effect ignores durations attributed to it.
Note: Does not remove the STATE_HELPLESS flag.
Note: At least in EEs, it can remove opcode #177 effects targeting an EFF with opcode #39. Does not always work when delayed.

#3 (0x3) State: Berserking Variants: IWD1
Parameter #1: Irrelevant
Parameter #2: Type
Description:
Applies the berserk effect to the targeted creature(s) in the style specified by the Type field.
Target will uncontrollably attack enemies if any are in view, and will occasionally attack neutral creatures.
Known values for Type are:
  • 0 ⟶ Default/In Combat: only berserk while in combat.
  • 1 ⟶ Constant: always berserk, maintains BERSERK_ALWAYS_ACTIVE (only in EEs).
  • 2 ⟶ Blood Rage: doesn't exist in EE's, values 2+ function the same as 0.

This opcode sets the STATE_BERSERK flag.

Note: Being “in combat” is reliant upon the presence of visible, non-sleeping enemies, but they will attack anyone they can see (including sleeping creatures), ally, neutral, or enemy, without preference (beyond whom is closer).
Info: STATE_BERSERK specs:
  • Grants a +2 bonus to THAC0 and Damage.
  • While "in combat" or "Constant":
    • Creature is unseletectable, Inventory is disabled.
    • The creature's AI scripts are disabled.
    • The creature will randomly execute action ~ AttackReevaluate([ANYONE],15) (or similar, the exact attack action is unknown).
    • Disables Saving while affecting a Party Member (Displayed message: "You do not control all your Party Members")
Note:
  • Forces creature(s) to use a melee weapon if possible.
    • If a certain creature is equipped with a Cursed ranged weapon, this opcode will not force it to switch to a melee weapon.
Note: This effect only affects party members (this is not true for EE games, it works fine on non-party creatures.)
Note: The second paragraph hasn’t been verified for PST and BG1 yet, but likely holds.
Important: Used with Timing Modes 1/4/7 results in setting STATE_BERSERK when it triggers (and using its default behavior), rather than attaching a removable effect with selected behavior.
Note: “Morale Failure: Berserk” does NOT use this or any of the other berserk opcodes, nor does it set STATE_BERSERK.

#4 (0x4) Cure: Berserking
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Removes opcode #3 effects and STATE_BERSERK from the targeted creature(s). Does not remove opcode #245, opcode #246 and opcode #247 effects.
This effect ignores durations attributed to it.
Important: Both parameters should be 0 (zero).
Note: At least in BG2 and EEs, this effect only affects player characters.
Note: At least in BG2 and EEs, this effect can remove opcode #177 effects targeting an EFF with opcode #3.

#5 (0x5) Charm: Charm Specific Creature Variants: IWD1 IWD2 PST
Parameter #1: General Type
Parameter #2: Charm Type
Description:

#6 (0x6) Stat: Charisma Modifier Variants: IWD1 PST
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Charisma = Charisma + 'Statistic Modifier' value

  • The opcode itself provides no coloring anymore (it's been externalized through "UI.menu")
    • An effective value > base value ⟶ green.
    • An effective value < base value ⟶ red.
    • An effective value = base value ⟶ white/default.
Important: With Timing Modes 1/4/7, the creature's base Charisma is altered, leaving behind no removable effect.

Info:
  • Each Item Type has 7 slots/locations, corresponding to a different set of Palette indexes that they will replace.
  • Near Infinity lists them as Grey, Cyan/Teal, Magenta/Pink, Yellow, Red, Blue, and Green.
    While these colors are arbitrary, they best represent the palette used in animation/paperdoll BAMs by default (before being recolored), so you can look at the BAM file and know which colors will be replaced.
  • 0=Grey, 1=Cyan, 2=Magenta, 3=Yellow, 4=Red, 5=Blue, 6=Green.
    +16 for weapons, +32 for shields, +48 for helmets.
  • The names already listed for some of these locations in IESDP are accurate, as they correspond to their general use in the vanilla game, but all 7 slots can be used for each item, provided their BAM file makes use of them.
  • Palette indexes will be replaced by the gradient specified for those locations:
    • Index 0–3 are reserved for Transparency and Shadows, they are not replaced.

The Dice values can be used to inflict varying damage amounts - e.g. 2d6 would do 2-12 damage (Damage type is still specified by the 'Type' value).
If 'Damage Amount' and the Dice values are both non-zero, the total damage inflicted is: 'Damage Amount' + Dice value.
'Damage Amount' can be positive or negative (though the damage sound will play in either case).

Note: ‘Stunning’ damage does not stun the target. Stunning damage cannot kill a creature, creatures are reduced to 1 HP and are knocked unconscious.
Warning: Using ‘Magic Fire’ or ‘Magic Cold’ as a damage type will result the game to crash if the damage kills the target.

#15 (0xF) Stat: Dexterity Modifier Variants: IWD1 IWD2 PST
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Dexterity = Dexterity + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: Dexterity = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Dexterity = (Dexterity * 'Statistic Modifier' value) / 100
  • 3 ⟶ Cat's Grace (EE only)

Statistic Modifier can be positive or negative.

The effect modifies DEX.
Info: All games but EEs:
  • With a Timing Modes of Permanent or Delayed, if Type is 0 and Statistic Modifier is positive, the statistic will alter and remain shown in white text, and a message 'Dexterity raised permanently' will be shown.
  • With a Timing Modes of Permanent or Delayed, if Type is 1 or 2, or Statistic Modifier is negative, the statistic will alter and remain shown in white text, though no message is shown.
  • With all other Timing Modes, the statistic will alter and be shown in red text.
On EEs:
  • There's no feedback message about stat being raised permanently in the EE's – it must be done separately with opcode #139.
  • The opcode itself provides no coloring anymore (it's been externalized through "UI.menu")
    • An effective value > base value ⟶ green.
    • An effective value < base value ⟶ red.
    • An effective value = base value ⟶ white/default.
Info: When Type=3:
  • Statistic Modifier is unused: it uses the value listed in CLSSPLAB.2da for the creature's base class, or defaults to 1 if the file isn't present (it only exists by default in IWDEE).
  • A single instance of this opcode (using Type=3) cannot raise Dexterity above 20 (hardcoded), but multiple instances of it can.
    • This is because it only checks the limit against the creature's base score, not its effective score.
  • Like the other modes, applying the effect with Timing Mode 1 will affect the creature's base stat, leaving no removable effect.
  • Once applied to a creature, Statistic Modifier will store the exact DEX increase granted (only useful for lookup/editing through EEkeeper/NI).
  • When you apply this effect in an External EFF, (via op177 / op283):
    • Parameter1 in the EFF will determine the exact Dexterity increase (so it must be set manually, and ignores any limit).
Important: With Timing Modes 1/4/7, the creature's base Dexterity is altered, leaving behind no removable effect.
Info: Final values are capped to the bound range (0,25) in game (40 in IWD2).

#16 (0x10) State: Haste Variants: IWD1
Parameter #1: Irrelevant
Parameter #2: Type
Description:
Applies the Haste effect, in the style specified by the Type value.
Known values for Type are:
  • 0 ⟶ Normal Haste – double the movement rate and grants an additional Attack Per Round (APR), rounded down (capped at 6)
  • 1 ⟶ Improved Haste – double the movement rate and doubles APR (capped at 10)
  • 2 ⟶ Weak Haste – Speed haste without attack bonuses, round APR up (capped at 5)


All of them set STATE_HASTED. Improved/Weak function by setting an additional STAT value, which modifies the behavior of STATE_HASTED:

The Normal and Improved haste types grant a -2 initiative (Weapon Speed) bonus. All types:

Info: This effect will cancel out the slow opcode.
Warning: BG1 only supports haste type 0.

This opcode will set the STATE_HASTED flag and nothing else when applied with Timing Mode 1, and cannot be removed within the game by any means, only suppressed by Slow.
This only works when applying Normal/Improved haste (there’s no difference, since the STAT for Improved haste doesn’t get set this way), Weak haste does not do anything with Timing Mode 1.

#17 (0x11) HP: Current HP Modifier Variants: IWD2 BG1
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: HP = HP + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: HP = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: HP = (HP * 'Statistic Modifier' value) / 100


Statistic Modifier can be positive or negative.
Note: If Statistic Modifier and the Dice values are both non-zero, the total HP change is: 'Statistic Modifier' + Dice value.


The upper word of the Type field can further control the style.
Known values for the upper word of Type are:
  • BIT0 ⟶ Raise dead
  • BIT1 ⟶ Remove all effects with a limited Timing Mode (not equipped(2) or permanent(9)), but also any ITM in the Magical Weapon Slot.
Important: Unlike opcode #12, this opcode does not apply any death effect (opcode #13) to the creature if it reduces their hit points to zero or less. The creature will remain in a bugged state (no HP but not dead) until they take further damage, or the game is saved & reloaded, at which point they will die properly.

#18 (0x12) HP: Maximum HP Modifier
Parameter #1: Statistic Modifier
Parameter #2: Type
Special: Mode
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: HP = HP + 'Statistic Modifier' value (affects current and max HP)
  • 1 ⟶ Flat Value Modifier: HP = 'Statistic Modifier' value (affects current and max HP)
  • 2 ⟶ Percentage Modifier: HP = (HP * 'Statistic Modifier' value) / 100 (affects current and max HP)
  • 3 ⟶ As 0 (does not affect current HP)
  • 4 ⟶ As 1 (does not affect current HP)
  • 5 ⟶ As 2 (does not affect current HP)
  • 6 ⟶ Non-cumulative Modifier: HP = HP + 'Statistic Modifier' value (affects current and max HP) (EE only)


Statistic Modifier can be positive or negative.

Known values for Mode are:
  • 0 ⟶ Normal: Effect functions as dictated by the Type field.
  • 1 ⟶ Do not update current HP.
    • This value is set automatically once the effect has been initially processed on a creature.
    • For normal operation, the special field MUST be zero.
Info: To differentiate non-cumulative HP gain from other forms of HP gain, Type is set internally to 6. As mentioned here, multiple effects of Type=6 can be carried by the creature at the same time and only the largest value is used when calculating extra HP. Hence the term “noncumulative coexisting”. This functionality doesn’t interact with other forms (Type != 6) of HP gain, and cumulative HP drain doesn’t use Type=6.
Note: For non-permanent timing modes of Type 2 or 5 use the base maximum HP value, and therefore override other Type 2 or 5 modifiers.
Note: If Statistic Modifier and the Dice values are both non-zero, the total HP change is: 'Statistic Modifier' + Dice value.
Note:
  • Maximum HP cannot be reduced below a creature's level/HD (average level rounded up for multiclasses).
  • It is still able to reduce current HP below the creature's level/HD, and has the same bugged death as opcode #17 if it reduces a creature to zero or less HP.

#19 (0x13) Stat: Intelligence Modifier Variants: IWD1
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Intelligence = Intelligence + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: Intelligence = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Intelligence = (Intelligence * 'Statistic Modifier' value) / 100

Statistic Modifier can be positive or negative.

The effect modifies INT.
Info: All games but EEs:
  • With a Timing Modes of Permanent or Delayed, if Type is 0 and Statistic Modifier is positive, the statistic will alter and remain shown in white text, and a message 'Intelligence raised permanently' will be shown.
  • With a Timing Modes of Permanent or Delayed, if Type is 1 or 2, or Statistic Modifier is negative, the statistic will alter and remain shown in white text, though no message is shown.
  • With all other Timing Modes, the statistic will alter and be shown in red text.
On EEs:
  • There's no feedback message about stat being raised permanently in the EE's – it must be done separately with opcode #139.
  • The opcode itself provides no coloring anymore (it's been externalized through "UI.menu")
    • An effective value > base value ⟶ green.
    • An effective value < base value ⟶ red.
    • An effective value = base value ⟶ white/default.
Important: With Timing Modes 1/4/7, the creature's base Intelligence is altered, leaving behind no removable effect.
Info: Final values are capped to the bound range (0,25) in game (40 in IWD2).

#20 (0x14) State: Invisibility Variants: BG1 IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Type
Description:
Applies the invisibility effect, in the style specified by the Type value.
Known values for Type are:
  • 0 ⟶ Normal Invisibility
  • 1 ⟶ Improved Invisibility
  • 2 ⟶ Weak Invisibility (EE only)
Info:
  • Normal Invisibility:
    • Grants a +4 bonus to melee attacks only.
      • In addition to that, an invisible creature with a (backstab value greater than 1) or (sneak attack value of at least 1d6) also ignores the target's dexterity AC modifier (see DEXMOD.2da), when attacking in melee, even if their weapon is unsuitable for backstabbing/sneak attacks.
    • Applying Normal Invisibility with Timing Modes other than 1/4/7 in an external EFF through opcode #183 will NOT terminate early due to hostile/aggressive action (similar to the constant invisibility provided by Mislead). Applying the same through opcode #177 or opcode #283 DOES terminate due to hostile/aggressive action as normal.
    • Applying Normal Invisibility with Timing Modes 1/4/7 will set the creature's base state STATE_INVISIBLE, while still leaving behind a removable (but irrelevant) effect. This state is not cleared on death, but it is still terminated by any hostile/aggressive action that would normally terminate invisibility.
  • Improved Invisibility:
    • Affected creature stays invisible after attack.
    • Does not provide saving throw bonuses outside EEs, where it provides a bonus of 4 to all.
    • Lingers after the duration is spent and act as permanent if used as a 'While Equipped' effect.
    • Applying Improved Invisibility will cause the effect to be duplicated, with the duplicate using Normal invisibility. There's no reason to apply both Normal and Improved invisibility in the same spell/item (unless you want them to have different probabilities/hd limits).
    • Applying Improved Invisibility with Timing Modes 1/4/7 will set the creature's base state STATE_IMPROVEDINVISIBILITY, and because it duplicates itself as Normal invisibility, STATE_INVISIBLE as well, while still leaving behind a removable (but irrelevant) effect for each. These states are not cleared on death.
    • The effects that remain when setting the base STATEs are irrelevant, at least in-game, because everything that can remove the STATEs will also remove the effect. The STATEs can however be removed separately through NI or EEkeeper, at which point the effect will once again reapply its STATE immediately upon loading the game.
  • Weak Invisibility:
    • It's the same type of invisibility as Improved Invisibility after you take a hostile action and reveal yourself.
    • Applying "Weak" Invisibility with Timing Modes 1/4/7 will function no differently than Timing Mode 0, aside from having no natural expiration timer.
    • Applying "Weak" Invisibility is otherwise the same as Improved Invisibility, except it doesn't duplicate itself with a Normal version, which is why it doesn't quality for backstabs.
Note: The “Stealth” modal ability of Thieves/Rangers/Monks applies this effect with the following values:
  • Parameter1 = 1 (unknown if any purpose)
  • Parameter2 = 0
  • Duration = 20
Note: Creatures attacking an invisible creature suffer a -4 penalty to hit, unless they are affected by opcode #193. Moreover, you cannot target an improved/weak invisible creature with spells unless you’re affected by opcode #193 or the spell can target invisible creatures.
Note: This opcode itself just sets or maintains (with a duration) the relevant STATEs. Everything else is a feature of STATE_INVISIBLE and/or STATE_IMPROVEDINVISIBILITY.

#21 (0x15) Stat: Lore Modifier Variants: IWD2
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Lore = Lore + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: Lore = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Lore = (Lore * 'Statistic Modifier' value) / 100

Statistic Modifier can be positive or negative.

The effect modifies LORE.
Warning: This effect does not work with Timing Mode 1.

#22 (0x16) Stat: Cumulative Luck Bonus Variants: IWD1 PST
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field. Luck affects the minimum damage caused by a weapon (up to the normal maximum damage of the weapon) and the attack roll modifier (up to a maximum of 20, excluding natural attack roll modifiers, e.g. high STR, invisibility etc) by Statistic Modifier amount. Statistic Modifier also affects the damge rolls of opponents (in feature blocks, not extension headers). The effect does not set STATE_LUCK.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Luck = Luck + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: Luck = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Luck = (Luck * 'Statistic Modifier' value) / 100
Info: Effects of Luck:
  • Modifies a creature's weapon damage die rolls (up/down to its maximum/minimum).
  • Modifies a creatures's attack roll [1d20] (up/down to its maximum/minimum).
  • Modifies non-weapon damage die rolls dealt to the creature (up/down to its maximum/minimum).
  • Modifies a creatures's initiative roll [1d6 - 4] for weapon attacks (up/down to its maximum/minimum). See opcode #190 for further details about weapon/attack speed.
  • Modifies a creatures's initiative roll [1d8 - 1] for movement (up/down to its maximum/minimum).
  • Modifies a creatures's skill roll [1d100] for Hiding in Shadows (up/down to its maximum/minimum).
  • Modifies a creatures's skill roll [1d100] for Set Traps (up/down to its maximum/minimum).
  • Modifies a creatures's skill roll [1d10] for Open Locks (up/down to its maximum/minimum).
  • Modifies a creatures's skill roll [1d10] for Bash Doors (up/down to its maximum/minimum).
  • Modifies a creatures's skill roll [1d10] for Disarm Trap (up/down to its maximum/minimum).
  • Modifies the chance for a Mirror Image to be struck, chance = ('number of images' + 'Statistic Modifier') / ('number of images' + 1).
Info: Here’s more info about initiative roll for movement:
  • Apparently, there is intentionally a random wait time between when a creature attempts to move to another creature, and when they will actually start pathing. Luck helps with this...
    Wait Time = 0, when roll = 0
    Wait Time = (8 - roll), when roll != 0
  • The natural roll range is [0,7], but like many other rolls Luck alters this slightly. For every point in Luck the highest bound of the roll is converted into the lower bound.
  • So with 1 Luck the roll becomes [0,6], with 0 having a probability of 25% instead of 12.5%. Negative luck works the same, but in reverse.
  • 1 is the worst roll you can get, yet it is neither of the extremes. So, -1 Luck is bad because it prevents you from bypassing the wait time, (rolling a 0), but if Luck must be negative, the lower the better.
    • Luck = "-1": Worst roll possible is a 1, you will be waiting for 7 AI updates (or, if you prefer, 715ths of a second).
    • Luck = "-7": Worst roll possible is a 7, you will be waiting for 1 AI update (or, if you prefer, 115th of a second)!!
  • Positive Luck will always increase the likelihood of instantaneous pathing.
  • Note that this wait time is only applied to creature-to-creature pathing, and never to on-the-ground destinations.
  • Also, every creature rolls for their own delay when they go to target a creature.

#23 (0x17) Stat: Morale Modifier Variants: BG1
Parameter #1: Statistic Modifier
Parameter #2: Type

1 Inflict 1HP per second (only if 'Damage Amount' is greater than 1)
2 Inflict 'Damage Amount' per second
3 Inflict 1HP every 'Damage Amount' seconds
4 Inflict Param 3 Damage every Param 1 seconds
5+ Crash

Important: The 'Damage Amount' parameter should be set to a positive value.

The effect modifies RESISTELECTRICITY.

#30 (0x1E) Stat: Fire Resistance Modifier Variants: IWD2
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Resistance = Resistance + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: Resistance = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Resistance = (Resistance * 'Statistic Modifier' value) / 100

Statistic Modifier can be positive or negative.

The effect modifies RESISTFIRE.

#31 (0x1F) Stat: Magic Damage Resistance Modifier Variants: BG1
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.

Statistic Modifier can be positive or negative.

The effect modifies MAGICDAMAGERESISTANCE.

#32 (0x20) Cure: Death (Raise Dead) Variants: IWD2
Parameter #1: Irrelevant
Parameter #2: Restore creature animation?
Description:
Raises the targeted creature(s) from the dead.
Known values for Restore creature animation? are:
  • 0 ⟶ No
  • 1 ⟶ Yes

This effect ignores durations attributed to it.
Info: The new animation is selected just as it would be at Character Generation.
Base Animation = 0x6000
  • + Class:
    • 0x0000 (Cleric/Druid/Shaman/Default)
    • 0x0100 (Fighter/Paladin/Ranger)
    • 0x0200 (Mage/Sorcerer)
    • 0x0300 (Thief/Bard)
    • 0x0500 (Monk)
    • Mutliclasses prioritize (Warrior > Priest > Rogue > Wizard)
  • + Gender:

    • 0x0003 (Halfling)
    • 0x0004 (Gnome)
    • 0x0005 (Halforc)
Note:
  • This opcode will only restore life to creatures with STATE_DEAD. Frozen and Petrified creatures do not qualify until after they shatter (at which point you can no longer target them outside of scripts, so it doesn't really matter).
  • The animation reset is not dependent on the target's death state.
Info: The presence of this opcode in any of a spell’s ability headers will force any Wild Surge of that spell to use the “Cast Normally” result.

#33 (0x21) Stat: Save vs. Death Modifier Variants: IWD2
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:

  • 1 ⟶ Flat Value Modifier: Save = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Save = (Save * 'Statistic Modifier' value) / 100
  • 3 ⟶ Increment Instantly: Save = Save + 'Statistic Modifier' value (EE only)

Statistic Modifier can be positive or negative.

The effect modifies SAVEVSDEATH.
Info: When Type = 3, this opcode processes before saving throws are checked for effects proceeding it in the same effect stack; when Type = 0, it processes after.

#34 (0x22) Stat: Save vs. Wands Modifier Variants: IWD2
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:

  • 1 ⟶ Flat Value Modifier: Save = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Save = (Save * 'Statistic Modifier' value) / 100
  • 3 ⟶ Increment Instantly: Save = Save + 'Statistic Modifier' value (EE only)

Statistic Modifier can be positive or negative.

The effect modifies SAVEVSWANDS.
Info: When Type = 3, this opcode processes before saving throws are checked for effects proceeding it in the same effect stack; when Type = 0, it processes after.

  • 3 ⟶ Increment Instantly: Save = Save + 'Statistic Modifier' value (EE only)

Statistic Modifier can be positive or negative.

The effect modifies SAVEVSBREATH.
Info: When Type = 3, this opcode processes before saving throws are checked for effects proceeding it in the same effect stack; when Type = 0, it processes after.

#38 (0x26) State: Silence
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Applies the silence effect to the targeted creature(s). Sets STATE_SILENCED to true.
A silenced creature cannot cast spells / use special abilities (unless flagged as Castable when silenced) or initiate dialog.
The engine is hard-coded to allow these spells to be cast by a silenced creature:
  • "SPWI219" (Vocalize)
  • "SPIN649" (Teleport to Pocket Plane) in BG2/BGEE

#39 (0x27) State: Unconsciousness Variants: IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Wake on Damage?
Special: Icon
Description:
Applies the unconsciousness effect to the targeted creature(s).
Known values for Wake on Damage? are (only in EEs):
  • 0 ⟶ Yes
  • 1 ⟶ No

Icon defines the index from STATDESC.2DA for custom portrait icons (EE only). Default value is Sleep.

This opcode sets the STATE_SLEEPING flag.

Note: Timing Modes 1/4/7 will set the STATE_HELPLESS flag. In such a case, this flag cannot be removed in-game.
Moreover, they will also set STATE_SLEEPING, which works as the Wake on Hit option. It’s just not usable because of the irremovable STATE_HELPLESS.

#40 (0x28) State: Slow
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Applies the slow effect to the targeted creature(s). It automatically grants the Slow portrait icon.
Info: This effect will cancel out the haste opcode.
Note: This effect doubles the Casting Time of all spells. Not verified for IWD2.
Warning: This opcode will set the STATE_SLOWED flag and nothing else when applied with Timing Mode 1, and cannot be removed within the game by any means, only suppressed by Haste.

#41 (0x29) Graphics: Sparkle Variants: BG1 IWD1 IWD2 PST
Parameter #1: Colour
Parameter #2: Type
Description:
Displays the sparkle effect specified by the Type field, in the colour specified by the Colour field. The colour field may be connected to SPRKLCLR.2DA.
Known values for Colour are:
  • 0 ⟶ Crash
  • 1 ⟶ Black
  • 2 ⟶ Blue
  • 3 ⟶ Chromatic
  • 4 ⟶ Gold
  • 5 ⟶ Green
  • 6 ⟶ Purple
  • 7 ⟶ Red
  • 8 ⟶ White
  • 9 ⟶ Ice
  • 10 ⟶ Stone
  • 11 ⟶ Magenta
  • 12 ⟶ Orange
  • 13+ ⟶ Crash

Known values for Type are:
  • 1 ⟶ Explosion
    • It is always instantaneous.
  • 2 ⟶ No effect?
  • 3 ⟶ Sparkle Shower
    • Will use the specified duration, but is not saved (lost upon reload).
Info: Both of these params use only the lower 16 bits (upper bits might have other function).

#42 (0x2A) Spell: Wizard Spell Slots Modifier Variants: IWD1
Parameter #1: Slot Amount Modifier
Parameter #2: Spell Level
Description:
Alters the number of wizard spell slots available to the targeted creature(s), as specified by the Slot Amount Modifier field, at the level specified by the Spell Level field. Wizard spells are used by Bards, Sorcerers and Wizards in IWD2.
Known values for Spell Level are:
  • 0 ⟶ Double spells
  • 1 ⟶ Level 1
  • 2 ⟶ Level 2
  • 4 ⟶ Level 3
  • 8 ⟶ Level 4
  • 16 ⟶ Level 5
  • 32 ⟶ Level 6
  • 64 ⟶ Level 7
  • 128 ⟶ Level 8
  • 255 ⟶ Level 9

For a Spell Level of 0, the amount of spell slots is doubled for the level specified by the Slot Amount Modifier value and all levels below. The target creature(s) must have at least 1 slot at the selected level to have their slot count changed.

Negative slots start at 65535 (-1), and go from there. Even though the spellbook has room to display only 12 slots at once, the slots are still there and usable.

Slot Amount Modifier can be positive or negative.
Note:
  • If the number of current spell slots is 1:
    • applying a -1 modifier will result in zero current slots and prevent further applications of this opcode from altering spell slots (until this effect terminates or is removed, or the base amount changes).
    • applying a -2 modifier instead would bypass zero and result in 65535 (-1). Then applying a +1 modifier would result in zero current slots and a repeat of the above.
  • Regardless of whether the value can be altered, the effect is still attached to the creature, rather than being discarded entirely. They can still take effect should the creature's base spell slots be altered (such as from leveling up).
  • Applying multiple effects in increments of -1 will insure that spell slots do not go below zero (and thus will not wrap around to maximum).

#43 (0x2B) Cure: Stone to Flesh
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Removes STATE_STONE_DEATH from the targeted creatures and restores them to 1 HP. Does not affect creatures without STATE_STONE_DEATH.
Important: Both parameters should be 0 (zero).
Note:
  • Will not remove a currently delayed (untriggered) Petrification effect.
  • Nor will it remove the False Petrification mode of opcode #109.

#44 (0x2C) Stat: Strength Modifier Variants: IWD1 IWD2 PST
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Strength = Strength + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: Strength = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Strength = (Strength * 'Statistic Modifier' value) / 100
  • 3 ⟶ Bull's Strength (EE only)

Statistic Modifier can be positive or negative.

The effect modifies STR.
Info: All games but EEs:
  • With a Timing Modes of Permanent or Delayed, if Type is 0 and Statistic Modifier is positive, the statistic will alter and remain shown in white text, and a message 'Strength raised permanently' will be shown.
  • With a Timing Modes of Permanent or Delayed, if Type is 1 or 2, or Statistic Modifier is negative, the statistic will alter and remain shown in white text, though no message is shown.
  • With all other Timing Modes, the statistic will alter and be shown in red text.
On EEs:
  • There's no feedback message about stat being raised permanently in the EE's – it must be done separately with opcode #139.
  • The opcode itself provides no coloring anymore (it's been externalized through "UI.menu")
    • An effective value > base value ⟶ green.
    • An effective value < base value ⟶ red.
    • An effective value = base value ⟶ white/default.
Info: When Type=3:
  • Statistic Modifier is unused: it uses the value listed in CLSSPLAB.2da for the creature's base class, or defaults to 1 if the file isn't present (it only exists by default in IWDEE).
  • A single instance of this opcode (using Type=3) cannot raise Strength above 18 (hardcoded), but multiple instances of it can.
    • This is because it only checks the limit against the creature's base score, not its effective score.
      • A Cleric with 12 base STR could gain up to +6 from the effect each time. Two max roll effects would take them to 24 STR.
      • A Cleric with 16 base STR could only gain up to +2 from the effect each time.
    • Warrior classes also gain a % Strength score, their maximum is actually 18/100. Every /10 is counted as +1 from their die roll. Warriors will not exceed 18/100 though, as once they hit 18, the remaining dice roll converts to a % increase, preventing their score from exceeding 18/100 (18/100 + /10 doesn't convert to 19).
      For instance, if a PALADIN with 17 STR rolls, say, 5, he will end up with 18/40 STR.
  • Like the other modes, applying the effect with Timing Mode 1 will affect the creature's base stat, leaving no removable effect.
  • Once applied to a creature, Statistic Modifier will store the exact STR increase granted, while the Special field will store any Exceptional STR increase granted (only useful for lookup/editing through EEkeeper/NI).
  • When you apply this effect in an External EFF, (via op177 / op283):
    • Parameter1 in the EFF will determine the exact Strength increase (so it must be set manually, and ignores any limit).
    • If Parameter1 is non-zero, Exceptional STR will still be rolled as normal (and only for appropriate Classes).
      • It will be equal to 10 * (Roll - (18 - Base)), capped (0,100).
    • If Parameter1 is zero, no Exceptional STR will be granted.
    • The actual increase for Exceptional STR will be stored in the Special field of op177 / op283 (after it's been applied to the creature).
    • Basically, it works exactly like Type=0, except that warriors will still gain a random Exceptional STR increase (of course it's only noticeable if their resulting STR is 18).
Important: With Timing Modes 1/4/7, the creature's base Strength is altered, leaving behind no removable effect.
Info: Final values are capped to the bound range (0,25) in game (40 in IWD2).

#45 (0x2D) State: Stun Variants: IWD1
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Stuns the targeted creature(s). In particular:
  • Maintains Portrait Icon Stun (EE only).
  • Immobilizes the creature, limiting it to instantaneous actions (INSTANT.IDS).
  • Maintains STATE_STUNNED.
    • Renders the creature unselectable and disable the Inventory.
  • Maintains STATE_HELPLESS.
    • Renders the creature unselectable and disable the Inventory.
    • Causes all attacks against the creature to automatically hit, disabling Critical Hits and misses.
Note: Applied with Timing Modes 1/4/7: will set the creature’s base STATE_STUNNED flag, while still leaving behind a separate removable effect.
  • Should you remove the effect without removing the state (through means other than opcode #46), the creature will be fully functional, just not controllable by the player (if it was).
  • By itself, STATE_STUNNED does not disable any scripts or limit which actions the creature may take. It needs its opcode's immobilization effect as well as STATE_HELPLESS to fully work.

#46 (0x2E) Cure: Stun (Unstun) Variants: PST
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Unstuns the targeted creature(s) (opcode #45). Also removes STATE_STUNNED from the creature.

#49 (0x31) Stat: Wisdom Modifier Variants: IWD1 PST
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Wisdom = Wisdom + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: Wisdom = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Wisdom = (Wisdom * 'Statistic Modifier' value) / 100

Statistic Modifier can be positive or negative.

The effect modifies WIS.
Info: All games but EEs:
  • With a Timing Modes of Permanent or Delayed, if Type is 0 and Statistic Modifier is positive, the statistic will alter and remain shown in white text, and a message 'Wisdom raised permanently' will be shown.
  • With a Timing Modes of Permanent or Delayed, if Type is 1 or 2, or Statistic Modifier is negative, the statistic will alter and remain shown in white text, though no message is shown.
  • With all other Timing Modes, the statistic will alter and be shown in red text.
On EEs:
  • There's no feedback message about stat being raised permanently in the EE's – it must be done separately with opcode #139.
  • The opcode itself provides no coloring anymore (it's been externalized through "UI.menu")
    • An effective value > base value ⟶ green.
    • An effective value < base value ⟶ red.
    • An effective value = base value ⟶ white/default.
Important: With Timing Modes 1/4/7, the creature's base Wisdom is altered, leaving behind no removable effect.
Info: Final values are capped to the bound range (0,25) in game (40 in IWD2).

#53 (0x35) Graphics: Animation Change Variants: IWD1 IWD2 PST
Parameter #1: Animation ID
Parameter #2: Type
Description:
Alters the animation of the targeted creature(s) to the animation specified by the Animation ID field, in the style specified by the Type field.
Known values for Animation ID are: (from ANIMATE.IDS – in decimal)
Known values for Type are:
  • 0 ⟶ Change target's animation to Animation ID (Low Priority)
  • 1 ⟶ Change target's animation to Source's Base Animation (Low Priority)
    • Normally used targeting oneself to reassert their base animation over previous op53,p2=0 effects.
  • 2 ⟶ Change target's animation to Animation ID (High Priority)
    • Has priority over other op53 effects using either p2=0 or p2=1, regardless of stacking order.
Important: Applied with Timing Modes 1/4/7, sets the creature's base animation, leaving no removable effect.

#54 (0x36) Stat: THAC0 Modifier Variants: IWD2
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: THAC0 = THAC0 + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: THAC0 = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: THAC0 = (THAC0 * 'Statistic Modifier' value) / 100
Note: This effect adjusts the base stat, rather than modified THAC0.

#55 (0x37) Death: Kill Creature Type Variants: PST
Parameter #1: IDS Entry
Parameter #2: IDS File
Description:
Kills the targeted creature(s) with HD less than those specified by the Dice values, if the target(s) match the IDS mask.

Parameter #1: Level
Parameter #2: Type
Description:
Dispels magic from the targeted creature(s) (excepting magical weapons eg. Spirtual Hammer). Depending on the value of the 'Type' field, the 'Level' field can be used to set the level of the effect.
Known values for 'Type' are:
  • 0 ⟶ Always dispel
  • 1 ⟶ Use Caster Level
  • 2 ⟶ Use 'Level' field

With 'Type' of 1 or 2, the base chance of successfully dispelling is 50%. This chance is modified by the relative levels of the dispeller to the caster. Each level below gives a -10% chance, each level above gives a +5% chance. There is always a 1% chance of success or failure.

#59 (0x3B) Stat: Stealth Modifier
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Stealth = Stealth + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: Stealth = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Stealth = (Stealth * 'Statistic Modifier' value) / 100
Note: In BG2 and EEs, this effect alters the Move Silently skill.
Important: Timing Modes 1/4/7 permanently alter the creature's Move Silently score, leaving no removable effect.
Note: (EE only) When Type = 0 and Timing Mode = 9, it modifies MOVESILENTLYMTPBONUS. The final value for this stat is multiplied by its percentage entry in THIEFSCL.2DA, capped to the range [0,255], before being included in the creature’s Move Silently score.

#60 (0x3C) Stat: Miscast Magic Variants: IWD1 BG1
Parameter #1: Percent Chance
Parameter #2: Type
Description:
The targeted creature(s) will fail to cast the type of spell specified by the Type field, Percent Chance percent of the time.
Known values for Type are:
  • 0 ⟶ Mage Spells
  • 1 ⟶ Cleric Spells
  • 2 ⟶ Innate Abilities
  • 3 ⟶ Mage Spells
  • 4 ⟶ Cleric Spells
  • 5 ⟶ Innate Abilities
This opcode increments SPELLFAILUREMAGE, SPELLFAILUREPRIEST and SPELL_FAILURE_INNATE, each of which is capped 0 – 100.

Type values of 0,1 or 2 display a message – "Spell Failed: casting failure" (on EE games, this string is specified by STRREF_FEEDBACK_SPELLFAILED_CASTFAILURE)

Type values of 3,4 or 5 display a message – "Spell failed due to dead magic" (on EE games, this string is specified by STRREF_FEEDBACK_SPELLFAILED_CASTFAILUREDEAD)
Note:
  • This opcode is cumulative with itself and the Deafness effect.
  • Spells with Ignore Dead/Wild Magic ignore the spell failure chance from this effect (regardless of using the Dead Magic mode).

#61 (0x3D) Crash Variants: BGEE IWD2
Parameter #1: Undefined
Parameter #2: Undefined
Description:
Warning: This effect crashes the game.
Note: This effect has previously been referenced as Alchemy.

#62 (0x3E) Spell: Priest Spell Slots Modifier Variants: IWD1
Parameter #1: Slot Amount Modifier
Parameter #2: Spell Level
Description:
Alters the number of priest spell slots available to the targeted creature(s), as specified by the Slot Amount Modifier field, at the level specified by the Spell Level field.
Known values for Spell Level are:
  • 0 ⟶ Double spells
  • 1 ⟶ Level 1
  • 2 ⟶ Level 2
  • 4 ⟶ Level 3
  • 8 ⟶ Level 4
  • 16 ⟶ Level 5
  • 32 ⟶ Level 6
  • 64 ⟶ Level 7

For a Spell Level of 0, the amount of spell slots is doubled for the level specified by the Slot Amount Modifier value and all levels below. The target creature(s) must have at least 1 slot at the selected level to have their slot count changed.

Negative slots start at 65535 (-1), and go from there. Even though the spellbook has room to display only 12 slots at once, the slots are still there and usable.

Slot Amount Modifier can be positive or negative.
Note:
  • If the number of current spell slots is 1:
    • applying a -1 modifier will result in zero current slots and prevent further applications of this opcode from altering spell slots (until this effect terminates or is removed, or the base amount changes).
    • applying a -2 modifier instead would bypass zero and result in 65535 (-1). Then applying a +1 modifier would result in zero current slots and a repeat of the above.
  • Regardless of whether the value can be altered, the effect is still attached to the creature, rather than being discarded entirely. They can still take effect should the creature's base spell slots be altered (such as from leveling up).
  • Applying multiple effects in increments of -1 will insure that spell slots do not go below zero (and thus will not wrap around to maximum).

#63 (0x3F) State: Infravision
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Gives the targeted creature(s) infravision and sets STATE_INFRAVISION.
Important: Both parameters should be 0 (zero).
Info: STATE_INFRAVISION specs:
While a creature with Infravision is currently selected,
  • all visible creatures with body heat that are currently in a "shadowed" part of the area receive a "warm" (red-shifted) overlay
  • body heat is determined by a creature's animation (INI file) using detected_by_infravision=1, or by opcode #342 (p1=1 & p2=1)
  • "shadowed" is determined by each area's Light Map "AR####LM.BMP"
    • Some areas have a separate Light Map for "nighttime" hours, "AR####LN.BMP"

#64 (0x40) State: Remove Infravision
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Removes infravision from the targeted creature(s).
This effect ignores durations attributed to it.
Note: This will not remove racial infravision.
Important: Both parameters should be 0 (zero).

#65 (0x41) Overlay: Blur
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Applies the blur effect to the targeted creature(s) and sets STATE_BLUR. Graphical displacement is affected by movement rate.
Important: Both parameters should be 0 (zero).
Note:
  • STATE_BLUR will maintain the effects of this opcode, once this opcode expires, but only until you save & reload.
  • If you set STATE_BLUR on a CRE file, it won't do anything by itself.
  • If you later apply opcode #65 to the creature, once it expires, the blur visual will remain until you save & reload, but will no longer update based on your movement rate (it will remain stuck at whatever it was when the opcode expired).

#66 (0x42) Graphics: Transparency Fade Variants: IWD1 PST
Parameter #1: Fade Amount
Parameter #2: Visual Effect
Description:
Fades the targeted creature(s) by the value in the amount specified by the Fade Amount field in the style specified by the Visual Effect field.
Known values for Fade Amount are:
  • 1 ⟶ Fully visible
  • ...
  • 255 ⟶ Almost invisible

Known values for Visual Effect are:
  • 0 ⟶ Draw instantly

  • 2 ⟶ Fade out


This effect sets TRANSLUCENT to Fade Amount.

#67 (0x43) Summon: Creature Summoning Variants: IWD2 PST
Parameter #1: Unknown
Parameter #2: Control
Description:
Summons a creature, with EA set to the Control field. The Resource key should be set to the filename of the creature to summon.
Known values for Control are:
  • 0 ⟶ Match target (hostile if no target)
  • 1 ⟶ Match target (hostile if no target)
  • 2 ⟶ As creature file
  • 3 ⟶ Match target (hostile if no target)
  • 4 ⟶ As creature file
  • 5 ⟶ Hostile to target
  • 6 ⟶ As creature file
  • 8 ⟶ As creature file
  • 255 ⟶ As creature file
Note:
  • Control values 0 and 1 are identical, 4 and 6 are identical, 3 and 5 are each unique, all other values are identical with each other.
  • Control values 3, 4, 5, and 6 summon the creature at the location of the effect target. All other values summon the creature at the location of the ability target.
Info:
  • (EE only) Resource 2 (external EFFs): Animation VVC/BAM file to be played at the summoned creature's location.
    Default is a hardcoded VVC using "SPBOOM.BAM" and palette #65. This is generally used as the "portal" animation.
  • (EE only) Resource 3 (external EFFs): Animation VVC/BAM file to be played at the location of the ability target.
  • Applies an opcode #271 to the summoned creature based on the duration of the Resource 2 (not exact). Creature will not appear/spawn until this animation finishes.
  • Applies a delayed opcode #215 with resource = "SPGFLSH1" to the summoned creature, delayed duration = 5 ticks less than the opcode #271.
  • Applies a delayed opcode #68 to the summoned creature based on effect duration (unless permanent).
  • When summoned, any temporary changes (such as from equipped items) to the creature's gender are made permanent.

#68 (0x44) Summon: Unsummon Creature
Parameter #1: Text Notification
Parameter #2: Irrelevant
Description:
Unsummons a creature, with feedback controlled by Text Notification.
Known values for Text Notification are:
  • 0 ⟶ No text notification
  • 1 ⟶ Show text notification
Note: At least in BG2 and EEs, the Resource key should be set to the filename of the animation to play when unsummoning the creature, and defaults to "SPGFLSH1" if left empty.
Note:
  • Has no effect on Party Members.
  • Moves the targeted creature(s) to area ".ARE" (a non-existant area). This deletes non-global creatures from the game.
  • Global creatures can still be recovered through scripts actions, such as MoveGlobalObject().

#69 (0x45) Protection: From Detection (Non-Detection)
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Applies the non-detection effect to the targeted creature(s), setting STATE_NONDETECTION while active. This effect is negated by opcode #70. While in the non-detection state, the creature is immune to opcode #47 and opcode #116, though they are affected by effects that remove illusionary protections by school or secondary type.
Important: Timing Modes 1/4/7 will permanently set the creature's STATE_NONDETECTION flag, leaving no removable effect. This flag is not cleared on death.

#70 (0x46) Cure: Non-Detection Variants: IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Removes opcode #69 and the STATE_NONDETECTION flag from the targeted creature(s).
This effect ignores durations attributed to it.

#71 (0x47) IDS: Sex Change
Parameter #1: Gender Modifier
Parameter #2: Type
Description:
Alters the gender of the targetted creature(s) to the value specified by the Gender Modifier field, in the style specified by the Type value.
Known values for Type are:
  • 0 ⟶ Reverse Gender
  • 1 ⟶ Flat Value Modifier: Gender = 'Statistic Modifier' value (values from GENDER.IDS)


The effect modifies SEX_CHANGED.
Note:
  • Reverse Gender also switches the second BIT of the lower BYTE of the creature's animation, which (for PC races), will switch between their male/female animations (0x60000x6010).
  • Other races can be setup this way, but do not occupy the necessary animation slots by default.
    For instance, VAMPIRE is 0x7F12, VAMPIRE_FEMALE is 0x7F22 (Male should be 0x7F02 and female 0x7F12 for it to work).

#72 (0x48) IDS: Set IDS State Variants: BG1 IWD2 PST
Parameter #1: IDS Entry
Parameter #2: IDS File
Description:
Alters the IDS state of the targeted creature(s) specified by the IDS File field, to the value specified by the IDS Entry field.
Known values for IDS File are:
Important:
  • Only reliable timing mode is Timing Mode 1 (all others are bugged and can convert to this timing mode under various circumstances).
  • Timing Modes 1/4/7 will permanently set the creature(s) IDS value, leaving no removable effect.

#73 (0x49) Stat: Extra Damage Modifier Variants: IWD1
Parameter #1: Statistic Modifier
Parameter #2: Modifier Type
Description:
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field. The effect is an additive modifier, like adding +10 damage.

Parameter #1: Spell Level
Parameter #2: Irrelevant
Description:
Gives the targeted creature(s) protection from effects (opcodes) whose Power attribute is equal to Spell Level (range: 0 – 9).
Info:
  • Each application of this opcode only protects against its specified Spell Level, not "up to" it.
  • Each effect in a spell/item is checked separately by this opcode.
  • CAN block effects of Secondary Type MagicAttack.
  • CAN block EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode can deflect effects through AoE projectiles.
  • CANNOT block non-hostile effects from self.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Deflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is deflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#103 (0x67) Text: Change Name
Parameter #1: String Reference
Parameter #2: Irrelevant

Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Reputation = Reputation + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: Reputation = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Reputation = (Reputation * 'Statistic Modifier' value) / 100
  • 3 ⟶ Increment Party Reputation by 10 * 'Statistic Modifier', cannot lower reputation below 100, will raise reputation to 100 if already less (only in EEs)
  • 4 ⟶ Reset Party Reputation to 100 (only in EEs)
The effect modifies REPUTATION.

#111 (0x6F) Item: Create Magical Weapon
Parameter #1: Amount
Parameter #2: Irrelevant
Description:
Creates the item specified by the resource key. The number of items created is controlled by the Amount field. The item is created in the Magical Weapon Slot.

#112 (0x70) Item: Remove Item
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Removes a single instance (or stack) of the item specified by the resource key from the targeted creature(s). Items in container items (e.g. Bags of Holding) will not be removed. If a creature has multiple instances of the item, the one in the lowest slot number (see SLOTS.IDS) is removed. "EFF_M02" is hard-coded to play when an item is removed. This effect should be used to remove equipped items (use opcode #123 for inventory items).

#113 (0x71) Empty: Variants: BG1
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
This opcode has no effect.
Note: It is still processed, so it will still interact with Spell Turning/Deflection/etc… just like any other effect.

Parameter #2: Irrelevant
Description:
Removes invisibility from the targeted creature(s). Also removes STATE_INVISIBLE and STATE_IMPROVEDINVISIBILITY.
This effect ignores durations attributed to it.
Important: Both parameters should be 0 (zero).
Info:
  • The only difference between this opcode and opcode #47 is their index – you can block one with opcode #101 without blocking the other. That's it.
  • Both remove the same effects/STATEs, both are blocked by opcode #69.
  • They might have been intended for identical function, different uses, similar to opcodes #5/#241 (Charm), but it never happened.
  • Opcode #116 is used extensively because the original BG1 used it, and didn't use opcode #47 at all.

#117 (0x75) Spell Effect: Reveal Area Variants: IWD2
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Reveals the current area.
Note: It does not remove the fog of war.

#118 (0x76) Empty: Variants: BG1
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
This opcode has no effect.
Note: It is still processed, so it will still interact with Spell Turning/Deflection/etc… just like any other effect.

#119 (0x77) Spell Effect: Mirror Image Variants: IWD1
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Applies the Mirror Image effect to the targeted creature(s). The number of images is dicated by the level of the caster.
The exact formula is 'Parameter1' = 2 + ('Caster Level of the spell containing op119' / 3).
Info:
  • A Wizard spell with op119 will use the caster's Wizard Casting Level.
  • A Priest spell with op119 will use the caster's Priest Casting Level.
  • An Innate spell with op119 will use the caster's Innate Casting Level.
Note: A side note about non-spellcaster classes:

A Mirror Image scroll used by a Thief with HLA Use Any Item will use the level 10 duration, but the level 1 Image count.
The scroll casts the spell at level 10, but the opcode checks the caster’s Wizard Caster Level (which for a Thief is 1).

#120 (0x78) Protection: from Weapons
Parameter #1: Enchantment
Parameter #2: Type
Description:
Gives the targeted creature(s) immunity to weapons as specified by the Type field. The Enchantment field is used if Type is set to 0.

  • Protected weapons will still trigger HitBy(), but will not interact with Mirror Image or Stone skins.
  • Blocks weapon damage, on-hit effects of the weapon, opcode #248 and opcode #249, regardless of the effects target.
  • Does NOT block effects from opcode #341 or opcode #361 from triggering.
  • Area-effect projectiles (f.i. Arrow of Detonation) only check for Weapon Immunity on the attacked target, and use that result for all caught within their area of effect.

#121 (0x79) Empty:
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
This opcode has no effect. Sometimes known as "Graphics: (Visual Animation Effect)".

  • Creature is NOT helpless – they still require an attack roll to be hit.
  • Creature is unselectable, Inventory is disabled.

Parameter #1: Irrelevant
Parameter #2: Type
Description:
Polymorphs the targeted creature(s) into the creature specified by the resource key, in the style specified by the Type field.
Known values for Type are:
  • 0 ⟶ Gain Resistances/statistics (spell-casting disabled)
  • 1 ⟶ Appearance only

This effect sets POLYMORPHED to 1 but only if Type=0.

If the resource key is empty, other Polymorph effects are removed, allowing for removal of permanent effects.

  • It will also remove any item in Magical Weapon Slot, whether or not it was supplying a Polymorph effect.

Bug: At least on EE games, this opcode is bugged when you shapechange between two different non-natural forms. In particular:
  • All your equipment will be considered as "unequipped" (in particular, you will lose passive bonuses/maluses granted by your Rings, Amulet, Helmet and the like).
Note: When Type is 0, this opcode sets Strength, Dexterity, Resistances (excluding Poison and Magic Damage), Base AC, Specific AC (Crushing/Slashing/Piercing/Missile), and Base APR.
Note: When the resource key is empty, and it subsequently clears other Polymorph effects, Type is used just like param#1 of opcode #337.
As a result, it will clear all Polymorph effects if Type = "-1", else it will only clear Polymorph effects that have a param#2 that matches.
Note: These two values are not functional (changing them does nothing), but they do get set on the effect.
Warning: The creature you’re polymorphing into cannot have STATE_SLEEPING, STATE_FROZEN_DEATH, STATE_STONE_DEATH, STATE_FLAME_DEATH, or STATE_DEAD set in its CRE file, or the game will crash.

Parameter #2: Irrelevant
Description:
Applies the chant effect to the targeted creature(s).
This opcode has the same effects as opcode #22, but maintains its own separate STATE.
This opcode modifies LUCK.

This opcode works as the reverse of Chant (positive values decrease Luck, negative values increase Luck).
Note:
  • While this opcode is "Non-Cumulative" (it sets values rather than increment), what it really does is stack in reverse standard order.
  • The base STATE set on the CRE file will override any effect applied to them (defaulting to a value of zero).
  • The oldest equipped effect will override newer equipped effects, and any equipped effect will override a non-equipped effect.
  • The oldest non-equipped effect will override newer non-equipped effects.
Note: Statistic Modifier only reads the first byte for its value, the last 3 bytes are ignored.

    • Setting the Ignore Center bit in the subspell's projectile will force its effects to check Magic Resistance on every target, even if the caster did target themselves. Though as its primary function is to cause the projectile to ignore the caster (not "center"), it still won't affect them if it's area-effect.
Note: If the target is a container, the Type parameter is ignored and treated as 0.
Info: See opcode #326 for some peculiarities of projectile behaviour for Type=2.

#147 (0x93) Spell: Learn Spell Variants: IWD2 PST BG1
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
The targeted creature(s) tries to learn the spell specified by the resource key.
Learning is successful when 1D100 <= the INT-dependent LEARN_SPELL value in INTMOD.2DA.

Note:

#148 (0x94) Spell: Cast Spell (at Point)
Parameter #1: Casting Level
Parameter #2: Type
Description:
Casts the spell specified by the resource key, at the level specified by the Casting Level field, in the style specified by the Type field. A Casting Level of 0 casts at the level of the casting creature.
Known values for Type are:
  • 0 ⟶ Normal Casting
  • 1 ⟶ Cast Instantly (ignore Casting Level)
Note: This opcode does not work if the target is a container in non-ee versions.
Info: This opcode should generally target Self. In particular:
  • The projectile of the subspell will originate from the target(s) of opcode #148.
  • If the SPL/ITM with opcode #148 targets a location, and doesn't have an area-effect projectile, there will be no target to cast on.
  • If the SPL/ITM with opcode #148 has an area-effect projectile, the spell in opcode #148 would be cast once for every valid target.
  • If this opcode uses the Cast Instantly option, then the target, not the caster, would cast the spell in opcode #148.

#149 (0x95) (Identify)
Parameter #1: Undefined
Parameter #2: Undefined
Description:
The use of this effect is unknown, and effect of its parameters are undefined.

  • 3 ⟶ No effect on targeted creature – New creature (specified by the resource key) is spawned at target's location
Note: Experience is given as normal for a kill (the party still has to be the one applying the effect to earn experience).

#152 (0x98) Spell Effect: Play Movie Variants: BG1 IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Plays the movie specified by the resource key.

#170 (0xAA) Graphics: Play Damage Animation Variants: PST
Parameter #1: Irrelevant
Parameter #2: Animation
Description:

  • 7 ⟶ "SPSHKIMP.BAM" Electricity 1
  • 8 ⟶ "SPSHKIMP.BAM" Electricity 2
  • 9 ⟶ "SPSHKIMP.BAM" Electricity 3
Info: On EE games:
  • For Animation=4/5/6 and Animation=7/8/9, this opcode actually pulls the animation from DMGTYPES.2DA, each playing both ANIMATION1 (those listed above) and ANIMATION2, for FIRE and ELECTRICITY, respectively. Does not play the SOUND associated with them though.
    • ANIMATION1 is the initial animation, ANIMATION2 is the lingering animation.
  • BGEE/BG2EE use the default * (hardcoded) entries for all damage types, but they can be overridden by setting entries in DMGTYPES.2DA, as IWDEE does.
  • The animations for Animation=1/2/3 are not pulled from DMGTYPES.2DA, they're most likely fully hardcoded.

#175 (0xAF) State: Hold Variants: BG1 IWD2 IWD1
Parameter #1: IDS Entry
Parameter #2: IDS File
Description:
Applies a yellow fade in graphic effect to the targeted creature(s), and shows the 'Held' icon, if the targeted creature(s) match the value specified by the IDS Entry field, in the specified IDS File. The affected creature becomes immobile and its AI scripts stop running.
Known values for IDS File are:
This effect sets HELD to 1. It also sets the STATE_HELPLESS flag.
Note: At least in EEs, this opcode automatically displays string STRREF_EFFECT_HOLD in the combat log. It even overrides the entries in EFFTEXT.2DA.

#176 (0xB0) Stat: Movement Modifier (II)
Parameter #1: Statistic Modifier
Parameter #2: Type
Description:
(As opcode #126, but unaffected by Free Action).
Applies the modifier value specified by the Statistic Modifier field in the style specified by the Type field.
The engine allows values for Statistic Modifier from 0 (immobile) to 255 (instantaneous), though behaviour is only consistent in the range 0 – 30.
Known values for Type are:
  • 0 ⟶ Cumulative Modifier: Movement = Movement + 'Statistic Modifier' value
  • 1 ⟶ Flat Value Modifier: Movement = 'Statistic Modifier' value
  • 2 ⟶ Non-stacking Percentage Modifier: Movement = (Movement * 'Statistic Modifier' value) / 100
  • 5 ⟶ Multiplicative Stacking Percentage Modifier: Movement = (Movement * 'Statistic Modifier' value) / 100 (EE only)
Warning: PST: This effect doesn’t exist and always crashes the game.
Info: A couple of examples about Multiplicative Stacking Percentage Modifier:
  • 50% * 50% = 25%
  • 150% * 150% = 225%

#177 (0xB1) Use EFF File
Parameter #1: IDS Entry
Parameter #2: IDS File
Description:
Applies the eff file specified by the resource key to the targeted creature(s), if the targeted creature(s) match the value specified by the IDS Entry field, in the specified IDS File.
NB. When using an eff to alter thac0/dmg bonus, set param1 = 0, and param2 = 2.
Known values for IDS File are:
Warning: This effect causes a crash if used by a container
PST: This effect doesn’t exist and always crashes the game.
IWD2: there was a note to not use this effect in older IESDP.

#178 (0xB2) Spell Effect: THAC0 vs. Creature Type Modifier Variants: PST BG1
Parameter #1: IDS Entry
Parameter #2: IDS File
Special: Statistic Modifier
Description:
Alters the targeted creature(s) THAC0 against the creature type specified by the IDS Entry field in the specified IDS File.
The actual modifier value is placed in the Parameter3 field in an external effect.
Known values for IDS File are:
Note:
  • It will affect all attacks, not just the weapon it's on, which would be incorrect when dual-wielding.
  • Multiple opcode #178 effects only allow additional targeting, they do not stack their THAC0 bonus.
Note: This opcode uses a reverse stacking order: the “oldest” effect with matching IDS values for the target is used, not the most recent, and equipped effects take priority over non-equipped effects.

#179 (0xB3) Spell Effect: Damage vs. Creature Type Modifier Variants: PST BG1
Parameter #1: IDS Entry
Parameter #2: IDS File
Special: Statistic Modifier
Description:
Alters the targeted creature(s) damage against the creature type specified by the IDS Entry field in the specified IDS File. The actual modifier value is placed in the Parameter3 field in an external EFF – dice values are ignored.
Known values for IDS File are:
Note:
  • It will affect all attacks, not just the weapon it's on, which would be incorrect when dual-wielding.
  • For two-handed/ranged weapons, it can be ideal if a base weapon damage bonus is desired.
  • Damage is multiplied by critical hits (and maybe backstabs).
  • Multiple opcode #179 effects only allow additional targeting, they do not stack their damage bonus.
Note: This opcode uses a reverse stacking order: the “oldest” effect with matching IDS values for the target is used, not the most recent, and equipped effects take priority over non-equipped effects.

#180 (0xB4) Item: Can't Use Item Variants: IWD2 PST
Parameter #1: String Reference
Parameter #2: Undefined
Description:
The targeted creatures(s) cannot use the item specified by the resource key. The strref specified by the String Reference field is displayed when an attempt to use the item is made.

#181 (0xB5) Item: Can't Use Itemtype Variants: BG1 BGEE IWD1 IWD2 PST
Parameter #1: String Reference
Parameter #2: Type
Description:
The targeted creature(s) cannot use the item type specified by the 'Type' field. The strref specified by the 'String Reference' field is displayed when at attempt to use such an item is made.
Important: This effect only works with 'Type' set to 0.

#182 (0xB6) Item: Apply Effect Item
Parameter #1: Unknown
Parameter #2: Unknown
Description:
Applies an effect when the specified item is equipped.
Warning: This effect has never been seen to work.
Warning: PST: This effect doesn’t exist and always crashes the game.

#183 (0xB7) Item: Apply Effect Itemtype Variants: IWD2 PST
Parameter #1: Undetermined
Parameter #2: Type
Description:
Applies the effect specified by the resource key to the targeted creature(s) when an item of the item type specified by the Type field is equipped.
Note: Ammo (i.e., Arrows, Bullets and Bolts) does not work well with this opcode. The Ammo Slots are always “Equipped”, even when they are not in use. In other words: they trigger opcode #183 just by being in a quiver slot, regardless of whether the correct launcher is equipped or even active.
The offhand has the same issue – even when disabled, it’s detected by this opcode as equipped.
Having said that, this opcode currently allows detecting a launcher using its automated ammo (such as Shortbow of Gesen).
Warning: This effect has never been seen to work. This is not true for EE games.

#184 (0xB8) Graphics: Passwall (Don't Jump)
Parameter #1: Undefined
Parameter #2: Jump
Description:
Allows creatures to be placed in impassable areas, based on the value of the Jump field.
Known values for Jump are:
  • 0 ⟶ Do Jump from impassable areas
  • 1+ ⟶ Don't Jump from impassable areas
Warning: PST: This effect doesn’t exist and always crashes the game.
IWD2: Don’t use.

#185 (0xB9) State: Hold (II) Variants: BG1 IWD2 PST
Parameter #1: IDS Entry
Parameter #2: IDS File
Description:
Applies a yellow fade in graphic effect to the targeted creature(s), and shows the 'Held' icon, if the targeted creature(s) match the value specified by the IDS Entry field, in the specified IDS File. The affected creature becomes immobile and its AI scripts stop running.
This effect is not removed by opcode #162.
Known values for IDS File are:
This effect sets HELD to 1. It also sets the STATE_HELPLESS flag.
Note: At least in EEs, this opcode automatically displays string STRREF_EFFECT_HOLD in the combat log. It even overrides the entries in EFFTEXT.2DA.

#186 (0xBA) Script: MoveToArea Variants: PST
Parameter #1: Delay
Parameter #2: Orientation
Description:
Marks the targetted creature(s) as travelling to the area specified by the resource key. The creature appears in the specified area after a delay (specified by the Delay field), with the orientation specified by the Orientation field.
In particular:
  • Global Creatures ignore the delay.
  • If the creature is already in the specified area, it will ignore the delay.
  • Non-global creatures currently in a different area than specified will use the delay.
  • Delay is measured in 130 seconds, (½ tick), 600 = 20 seconds.
  • On non-EE games, the creature appears at the point specified by the Target Point fields (external EFF files only).
    • On EE games, target(s) appear at Caster's Coordinates in new area (it does not seem to be possible to override through EFFs).
  • Creature is moved to the new area (instantly) and flagged Moving Between Areas until their delay expires (if it's used). It won't be active until the delay expires (it's hidden, cannot be affected by Area-effect, doesn't occupy space). It can still be targeted by the various Everyone targeting modes in the new area while it's still inactive, but similar to maze/imprisonment, effects won't trigger (including poison and similar) on them until they become active.
Warning: IWD2: there was a note to not use this effect in older IESDP.
There is some confusion whether the Target (bg1, iwds) or the Caster point field is used.
Important: Avoid saving during the delay (can lead to lost NPCs or crashes if you load while NPC's are still in transition).

#187 (0xBB) Script: Store Local Variable Variants: BG1 PST
Parameter #1: Value
Parameter #2: Irrelevant
Description:
This effect sets the variable specified by the Variable Name field to the value specified by the Value field.
Important: This effect can only be used in an external effect (CRE/EFF file).
Info: This effect is always instantaneous (local variables are stored internally, not as effects, while the game is running). All local variables for a CRE are stored as opcode #187 effects on that CRE whenever the game is saved, which will trigger as soon as the game is loaded.

#188 (0xBC) Spell Effect: Aura Cleansing Variants: PST
Parameter #1: Irrelevant
Parameter #2: Stat Value
Description:
While ON, the creature displays string STRREF_FEEDBACK_AURA_CLEANSED (EE games only) whenever they begin to cast a spell before their aura would normally clear (i.e. more than once/round). Does NOT affect item usage, only spellcasting.
Set the Stat Value field to any non-zero value if you want no time needed between spells.

The effect modifies AURACLEANSING to Stat Value.
Note: The Stat Value parameter can take any value. If you set it to 0, you will disable the effect (for its duration).

#189 (0xBD) Stat: Casting Time Modifier Variants: BG1 PST
Parameter #1: Speed Modifier
Parameter #2: Type
Description:
Alters the Casting Time of spells by the value specified by the Speed Modifier field. This effect is cummulative.
This effect sets MENTALSPEED to Speed Modifier. Known value for Type are:
  • 0 ⟶ Increment by Speed Modifier
    • Positive values decrease the casting time, negative values increase the casting time.
  • 1 ⟶ Set casting time of every spell to Speed Modifier
    • Negative values set casting time to 0
  • 2 ⟶ Set casting time of spells with casting time higher than Speed Modifier to Speed Modifier
    • Other spells are unaffected.
Note: Type=2 was tested only for BGEE and might not work on non-EE.

#190 (0xBE) Stat: Attack Speed Factor Variants: PST
Parameter #1: Speed Modifier
Parameter #2: Irrelevant
Description:
Alters the weapon's attack speed by the value specified by the Speed Modifier field. This effect is not cumulative. Attack speed ranges from 0 (good) to 10 (bad). This effect acts as a bonus, so a high Speed Modifier is good.
This effect sets PHYSICALSPEED to Speed Modifier.

#191 (0xBF) Spell: Casting Level Modifier Variants: BGEE IWD1 PST
Parameter #1: Modifier
Parameter #2: Type
Description:
Applies the value specified by the 'Modifier' field as a bonus to casting spell levels, of a type specified by the 'Type' field.
Known values for 'Type' are:
0 Mage
1 Cleric

This effect modifies stats #79 (CASTINGLEVELBONUSMAGE) or #80 (CASTINGLEVELBONUSCLERIC) depending on param #2.
Note: This effect changes the casting level stat, but has no actual affect in-game.

#192 (0xC0) Spell Effect: Find Familiar Variants: IWD1 PST
Parameter #1: Irrelevant
Parameter #2: Upgrade Marker
Description:
Applies opcode #195, opcode #196, and opcode #268 to the summoned familiar.
The Familiar summoned is based on the alignment of the Protagonist and values stored in the GAM file (non-EE games) or FAMILIAR.2DA (EE games).
On non-EE games, the Upgrade Marker field is used internally to indicate the familiar has received the ToB upgrades.
  • On EE games, if there is an Upgrade Marker, it isn't on opcode #192 (needs researching...).

On non-EE games, default creatures for familiars are:
  • Lawful Good ⟶ Pseudo Dragon (FAMPSD)
  • Lawful Neutral ⟶ Ferret (FAMFER)
  • Lawful Evil ⟶ Imp (FAMIMP)
  • Neutral Good ⟶ Pseudo Dragon (FAMPSD)
  • True Neutral ⟶ Rabbit (FAMRAB)
  • Neutral Evil ⟶ Dust Mephit (FAMDUST)
  • Chaotic Good ⟶ Fairy Dragon (FAMFAIR)
  • Chaotic Neutral ⟶ Cat (FAMCAT)
  • Chaotic Evil ⟶ Quasit (FAMQUAS)
Info: The familiars (CRE) available are locked in once a new game begins (any changes to FAMILIAR.2DA must occur before starting a new game).
Info: Max HP boost for summoning a familiar (and eventually loss when it dies) is ½ the familiar’s Max HP (including any CON bonus) at the time of summoning.
Note: The familiar restriction to <CHARNAME> is game-specific. IWDEE has no such restriction, but still only allows a single character to have a familiar at a time. It’s unclear if it’s a specific flag in the GAM file or if it’s engine-side.

#193 (0xC1) Spell Effect: Invisible Detection by Script Variants: IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Stat Value
Description:
Allows invisible creatures to be attacked (via scripts) and makes it possible to target improved invisible creatures with spells.

The effect modifies SEEINVISIBLE to Stat Value.
Note: The Stat Value parameter can take any value. If you set it to 0, you will disable the effect (for its duration).

#194 (0xC2) Ignore Dialog Pause Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Stat Value
Description:
Allows the targeted creature(s) to carry on their actions during dialogs which pause action.

The effect modifies IGNOREDIALOGPAUSE to Stat Value.
Note: The Stat Value parameter can take any value. If you set it to 0, you will disable the effect (for its duration).

#195 (0xC3) Spell Effect: Death Dependent Constitution Loss (Familiar Bond) Variants: IWD1 PST
Parameter #1: Max HP Modifier
Parameter #2: Unused
Parameter #3: Master ID (owner)
Description:
When this creature dies, the following is applied to Master ID:
  • Floats Text String STRREF_GUI_MIXED_FAMILIARDIED.
  • Opcode #10: Statistic Modifier = -1, Type = 0, Timing Mode 1.
  • Opcode #18: Statistic Modifier = Max HP Modifier, Type = 0, Timing Mode 1.
    • Opcode #192 sets Max HP Modifier to -½ the familiar's Max HP
  • Opcode #12: Damage Amount = 'this creature's Max HP', Type = MAGIC, Timing Mode 1, Save Type = Bypass Mirror Image.
    • Normally, Maximum HP of Master ID is lowered by Max HP Modifier, and Current HP is lowered by twice Max HP Modifier (since Max Hp Modifier = ½ familiar's Max HP).
      It won't be if the familiar's Max HP is increased (or decreased) permanently after it is summoned (temporary changes to Max HP will be removed by death before it deals damage, and so they won't affect the amount).
      Permanent changes to the familiar's Constitution, enough to alter the bonus HP it grants, will have similar results.
Known values for Master ID are:
  • -1 ⟶ Not Party Member
  • 0 ⟶ Player1
  • 1 ⟶ Player2
  • 2 ⟶ Player3
  • 3 ⟶ Player4
  • 4 ⟶ Player5
  • 5 ⟶ Player6
Important: Needs Timing Mode 9, otherwise it will be removed (by death) before it fully triggers.
Note: Parameter2 is possibly intended to be Damage Type. It uses the same format as opcode #12 (opcode #192 sets it to 0x400000 – MAGIC), but changing it has no effect.

#196 (0xC4) Spell Effect: Familiar Block Variants: IWD1 PST
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
If this effect is found on any creature in the GAM file, the engine will block summoning of more familiars.
Important: The effect should be set with a Timing Mode of 9.

#197 (0xC5) Spell: Bounce (by Impact Projectile) Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Impact Projectile
Description:
The targeted creature(s) will reflect effects whose Projectile is equal to the one specified by the Impact Projectile field back to the attacker.

V1 effects inherit their Projectile from the Extended Header (SPL / ITM), V2 effects specify it manually.

Values for Impact Projectile are taken from PROJECTL.IDS.

Important:
  • Area-Effect projectiles only impact through their explosion and/or secondary projectiles, so they are what must be specified in Impact Projectile.
  • Opcode #333, opcode #326 and opcode #146*p2=2 are NOT properly reflected by this opcode – the spell specified by their resource key will affect the original target (as if it wasn't reflected).
Info:
  • CANNOT reflect effects of Secondary Type MagicAttack.
  • CAN reflect EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode can reflect effects through AoE projectiles.
  • CANNOT reflect effects from self.
  • Maintains animation SPTURNI2 on the target, can be suppressed by opcode #291.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Reflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is reflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#198 (0xC6) Spell: Bounce (by Opcode) Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Opcode
Description:
The targeted creature(s) will reflect effects containing the opcode specified by the Opcode field.
Warning: This can cause a crash if two creatures end up reflecting to each other.
Important: Opcode #333, opcode #326 and opcode #146*p2=2 are NOT properly reflected by this opcode – the spell specified by their resource key will affect the original target (as if it wasn't reflected).
Info:
  • CANNOT reflect effects of Secondary Type MagicAttack.
  • CAN reflect EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode can reflect effects through AoE projectiles.
  • CANNOT block effects from self.
  • Maintains portrait icon Spell Deflection on the target (this is likely a bug).
  • Maintains animation SPTURNI2 on the target, can be suppressed by opcode #291.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Reflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is reflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#199 (0xC7) Spell: Bounce (by Power Level) Variants: IWD1 IWD2 PST
Parameter #1: Power Level
Parameter #2: Irrelevant
Description:
The targeted creature(s) will reflect effects whose Power attribute is equal to the one specified by the Power Level field (range: 0 – 9).
Important: Opcode #333, opcode #326 and opcode #146*p2=2 are NOT properly reflected by this opcode – the spell specified by their resource key will affect the original target (as if it wasn't reflected).
Info:
  • CANNOT block effects of Secondary Type MagicAttack.
  • CANNOT block EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode cannot reflect effects through AoE projectiles.
  • CANNOT block effects from self.
  • Maintains portrait icon Spell Deflection on the target (this is likely a bug).
Note: EFF files delivered by opcode #177/opcode #283 will interact with Reflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is reflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#200 (0xC8) Spell: Bounce (by Power level, decrementing) Variants: IWD1 IWD2 PST
Parameter #1: Total Amount
Parameter #2: Power Level
Description:
The targeted creature(s) will reflect a number of effects (specified by the Total Amount field) whose Power attribute is equal to the one specified by the Power Level field (range: 0 – 9).

The Power level of the first effect to trigger any instance of this opcode's reflection will determine how much this opcode's Total Amount is decremented. Every instance of this opcode on the creature will be decremented by this amount.

  • Example – Minor Spell Turning applies opcode #200 4 times, with parameter2 = (1, 2, 3, and 4), and parameter1 based on caster level. If any of them trigger, all of them will be decremented by the same amount. It doesn't matter that they come from the same spell. If you cast both Spell Turning and Minor Spell Turning, all instances of opcode #200 from both spells would be decremented, even if the spell(effect) triggering it was level 5–9 (above what Minor Spell Turning can reflect).

On EE games, resource field ⟶ Spell cast when this effect self-terminates, default = Parent + "B".

Important: As of EE v2.6, spells can no longer be "chained" back and forth by reflection.

If Caster and Target are both affected by this opcode, the spell from Caster will reflect off Target, but not reflect back off Caster. Previously, whoever had more reflection charges would end up victorious, now the initial target always ends up victorious.
Info:
  • CANNOT block effects of Secondary Type MagicAttack.
  • CANNOT block EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode cannot reflect effects through AoE projectiles.
  • CANNOT block effects from self.
  • Maintains portrait icon Spell Turning on the target.
  • Maintains animation SPTURNI2 on the target, can be suppressed by opcode #291.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Reflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is reflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#201 (0xC9) Spell: Immunity (by Power Level, decrementing) Variants: IWD1 IWD2 PST
Parameter #1: Total Amount
Parameter #2: Power Level
Description:
The targeted creature(s) will absorb a number of effects (specified by the Total Amount field) whose Power attribute is equal to the one specified by the Power Level field (range: 0 – 9).

The Power level of the first effect to trigger any instance of this opcode's deflection will determine how much this opcode's Total Amount is decremented. Every instance of this opcode on the creature will be decremented by this amount.

On EE games, resource field ⟶ Spell cast when this effect self-terminates, default = Parent + "B".

Info:
  • CANNOT block effects of Secondary Type MagicAttack.
  • CANNOT block EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode cannot deflect effects through AoE projectiles.
  • CANNOT block effects from self.
  • Maintains portrait icon Spell Deflection on the target.
  • Maintains animation SPMAGGLO on the target, can be suppressed by opcode #291.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Deflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is deflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#202 (0xCA) Spell: Bounce (by School) Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: School
Description:
The targeted creature(s) will turn effects from the school specified by the School field.

V1 effects inherit their Primary Type (School) from the Header(SPL) / Extended Header(ITM), V2 effects specify it manually.

Known values for School are:
  • 0 ⟶ NONE
  • 1 ⟶ ABJURATION
  • 2 ⟶ CONJURATION
  • 3 ⟶ DIVINATION
  • 4 ⟶ ENCHANTMENT
  • 5 ⟶ ILLUSION
  • 6 ⟶ EVOCATION
  • 7 ⟶ NECROMANCY
  • 8 ⟶ ALTERATION
  • 9 ⟶ GENERALIST
  • 10 ⟶ WILDMAGE
Important: Opcode #333, opcode #326 and opcode #146*p2=2 are NOT properly reflected by this opcode – the spell specified by their resource key will affect the original target (as if it wasn't reflected).
Info:
  • CANNOT reflect effects of Secondary Type MagicAttack.
  • CAN reflect EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode can reflect effects through AoE projectiles.
  • CANNOT reflect effects from self.
  • Maintains portrait icon Spell Deflection on the target (this is likely a bug).
  • Maintains animation SPTURNI2 on the target, can be suppressed by opcode #291.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Reflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is reflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#203 (0xCB) Spell: Bounce (by Secondary Type) Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Secondary Type
Description:
The targeted creature(s) will turn effects with a secondary type matching that specified by the Secondary Type field.

V1 effects inherit their Secondary Type from the Header(SPL) / Extended Header(ITM), V2 effects specify it manually.

Known values for Secondary Type are:
  • 0 ⟶ NONE
  • 1 ⟶ SPELLPROTECTIONS
  • 2 ⟶ SPECIFICPROTECTIONS
  • 3 ⟶ ILLUSIONARYPROTECTIONS
  • 4 ⟶ MAGICATTACK
  • 5 ⟶ DIVINATIONATTACK

  • 9 ⟶ BATTLEGROUND
  • 10 ⟶ OFFENSIVEDAMAGE
  • 11 ⟶ DISABLING
  • 12 ⟶ COMBINATION
  • 13 ⟶ NON-COMBAT
Important: Opcode #333, opcode #326 and opcode #146*p2=2 are NOT properly reflected by this opcode – the spell specified by their resource key will affect the original target (as if it wasn't reflected).
Info:
  • CANNOT reflect effects of Secondary Type MagicAttack.

Note: EFF files delivered by opcode #177/opcode #283 will interact with Reflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is reflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#204 (0xCC) Spell: Protection (by School) Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: School
Description:
Gives the targeted creature(s) immunity to effects from the school specified by the School field.

V1 effects inherit their Primary Type (School) from the Header(SPL) / Extended Header(ITM), V2 effects specify it manually.

Known values for School are:
  • 0 ⟶ NONE
  • 1 ⟶ ABJURATION
  • 2 ⟶ CONJURATION
  • 3 ⟶ DIVINATION
  • 4 ⟶ ENCHANTMENT
  • 5 ⟶ ILLUSION
  • 6 ⟶ EVOCATION
  • 7 ⟶ NECROMANCY

Info:
  • CANNOT block effects of Secondary Type MagicAttack.
  • CAN block EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode can deflect effects through AoE projectiles.
  • CANNOT block effects from self.
  • Maintains animation SPMAGGLO on the target, can be suppressed by opcode #291.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Deflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is deflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#205 (0xCD) Spell: Protection (by Secondary Type) Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Secondary Type
Description:
Gives the targeted creature(s) immunity to effects from the secondary type specified by the Secondary Type field.

V1 effects inherit their Secondary Type from the Header(SPL) / Extended Header(ITM), V2 effects specify it manually.

Known values for Secondary Type are:
  • 0 ⟶ NONE

  • CANNOT block effects from self.
  • Maintains animation SPMAGGLO on the target, can be suppressed by opcode #291.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Deflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is deflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#206 (0xCE) Spell: Protection from Spell Variants: IWD1 PST
Parameter #1: String Reference
Parameter #2: Irrelevant
Description:
Gives the targeted creature(s) immunity from the spell specified in the resource key. The strref specified by the String Reference field is displayed when the spell is absorbed.
Info: At least in EEs, this opcode can block EFF files too.
In order to do so, both the Resource field of opcode #206 and the Parent Resource field of the EFF file must be the same string (max. 8 character long); moreover, you must set the Resource Type field of the EFF file to Spell.

#207 (0xCF) Spell: Bounce (by Resource) Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
The targeted creature(s) will reflect the SPL file specified by the resource key.
Important: Opcode #333, opcode #326 and opcode #146*p2=2 are NOT properly reflected by this opcode – the spell specified by their resource key will affect the original target (as if it wasn't reflected).
Info:
  • Similar to opcode #206, this can only reflect EFF files if their Parent Type is set to Spell.
  • CANNOT reflect effects of Secondary Type MagicAttack.
  • CAN reflect EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode can reflect effects through AoE projectiles.
  • CANNOT reflect effects from self.
  • Maintains portrait icon Spell Deflection on the target (this is likely a bug).
  • Maintains animation SPTURNI2 on the target, can be suppressed by opcode #291.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Reflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is reflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#208 (0xD0) HP: Minimum Limit Variants: PST
Parameter #1: Minimum Value
Parameter #2: Irrelevant
Description:
The targeted creature(s) HP value will not drop below the value specified by the Minimum Value field.
This effect sets MINHITPOINTS to Minimum Value.
Note:
  • Minimum Value values 65536 to 98303 will set an only allowed hit point value (HP can't be higher or lower), each representing 'Minimum Value' value - 65536, so 0 to 32767.
  • Values 32768 to 65535 do this as well, but all result in negative HP amounts, so not usable, as they will result in the same bugged non-death as opcode #17 reducing HP to 0.
  • All values higher than 98303 just repeat loop over from -32768 to 32767.
  • Any positive value will also grant the creature immunity to directly applied opcode #13 effects. Those applied indirectly will still kill the creature, notably by opcodes #55, #134, #151, #209, and #238.

#209 (0xD1) Death: Kill 60HP Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Instantly kills the targeted creature(s), if the targeted creature(s) has less than 60 HP.
More specifically, it functions by applying opcode #13 (Death Type = 4 // Normal Death).
Note: Immunity to opcode #13 is not sufficient to block this effect unless it’s granted through 7EYES.2DA.

#210 (0xD2) Spell Effect: Stun 90HP Variants: IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Applies the stun effect to the targeted creature(s), if the targeted creature(s) has less than 90 HP.
The duration of the effect is:
  • 1 to 29 HP ⟶ stunned for 4d4 rounds
  • 30 to 59 HP ⟶ stunned for 2d4 rounds
  • 60 to 89 HP ⟶ stunned for 1d4 rounds
More specifically, it functions by applying opcode #45.
Note: Immunity to opcode #45 is sufficient to block the stun effect, but without immunity to opcode #210 it will still generate an erroneous ~Stunned~ string display.

#211 (0xD3) Spell Effect: Imprisonment Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Applies the imprisonment effect to the targeted creature(s).
The field at 0xcc can be used to prevent death related effects (e.g. removal from party) running on the targetted creature(s) – not verified on EE games (it is very likely that this was replaced by giving Maze a specified duration option).

Aside from kicking from the party, or granting experience for a kill, the targeted creature(s) is suspended from the area:
  • They can not be targeted by Area-Effect projectiles, only with effect targets Party or Everyone or similar.
  • They are not detectable by any script triggers, though they may still be targeted with actions directly by scriptname or partyslot.
  • Excluding Opcodes #211/#212/#213:
    • All other effects on the creature are suppressed until this effect is removed.
  • Excluding opcode #212:
    • Delayed effects that would trigger will be further delayed until this effect is removed.
    • Effects that would expire will not expire until this effect is removed.

#212 (0xD4) Protection: Freedom Variants: IWD1 IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Applies the freedom effect to the targeted creature(s).
Removes Imprisonment and Maze, and EFF files using those opcodes.

#213 (0xD5) Spell Effect: Maze Variants: IWD1 IWD2
Parameter #1: Type
Parameter #2: Irrelevant
Special: Icon
Description:
Applies the maze effect to the targeted creature(s).

Suspends the creature in the same manner as Imprisonment, disabling Inventory and removing all active Portrait Icons (except its own), but without kicking or granting exp. It actually removes itself with a delayed opcode #212 effect (that it also applies), not by expiring. Blocking the opcode #212 effect will prevent maze from ending.


Known values for Type are:
  • 0 ⟶ Use intelligence based duration (via INTMOD.2DA)

  • 10 ⟶ WILDMAGE

On EE games, resource field ⟶ Spell cast when this effect self-terminates, default = Parent + "B".

Info:
  • CANNOT block effects of Secondary Type MagicAttack.
  • CAN block EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode can deflect effects through AoE projectiles.
  • CANNOT block effects from self.
  • Maintains portrait icon Spell Shield on the target.
  • Maintains animation SPMAGGLO on the target, can be suppressed by opcode #291.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Deflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is deflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#224 (0xE0) Cure: Level Drain (Restoration) Variants: IWD1 IWD2

Parameter #1: Total Amount
Parameter #2: Secondary Type
Description:
The targeted creature(s) will absorb a number of effects (specified by the Total Amount field) whose Secondary Type is equal to the one specified by the Secondary Type field.

V1 effects inherit their Secondary Type from the Header(SPL) / Extended Header(ITM), V2 effects specify it manually.

The Power level of the first effect to trigger any instance of this opcode's deflection will determine how much this opcode's Total Amount is decremented. Every instance of this opcode on the creature will be decremented by this amount.

Known values for Secondary Type are:
  • 0 ⟶ NONE

If the opcode #177/opcode #283 effect is deflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#227 (0xE3) Spell: Bounce (by School, decrementing) Variants: IWD1 IWD2
Parameter #1: Total Amount
Parameter #2: School
Description:
The targeted creature(s) will reflect a number of effects (specified by the Total Amount field) whose Primary Type (School) is equal to the one specified by the School field.

V1 effects inherit their Primary Type (School) from the Header(SPL) / Extended Header(ITM), V2 effects specify it manually.

The Power level of the first effect to trigger any instance of this opcode's reflection will determine how much this opcode's Total Amount is decremented. Every instance of this opcode on the creature will be decremented by this amount.

Known values for School are:
  • 0 ⟶ NONE
  • 1 ⟶ ABJURATION
  • 2 ⟶ CONJURATION
  • 3 ⟶ DIVINATION
  • 4 ⟶ ENCHANTMENT
  • 5 ⟶ ILLUSION
  • 6 ⟶ EVOCATION
  • 7 ⟶ NECROMANCY
  • 8 ⟶ ALTERATION
  • 9 ⟶ GENERALIST
  • 10 ⟶ WILDMAGE

On EE games, resource field ⟶ Spell cast when this effect self-terminates, default = Parent + "B".

Important: As of EE v2.6, spells can no longer be "chained" back and forth by reflection.

If Caster and Target are both affected by this opcode, the spell from Caster will reflect off Target, but not reflect back off Caster. Previously, whoever had more reflection charges would end up victorious, now the initial target always ends up victorious.
Info:
  • CANNOT reflect effects of Secondary Type MagicAttack.
  • CAN reflect EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode can reflect effects through AoE projectiles.
  • CANNOT reflect effects from self.
  • Maintains portrait icon Spell Deflection on the target (this is likely a bug).
  • Maintains animation SPTURNI2 on the target, can be suppressed by opcode #291.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Reflection separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is reflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#228 (0xE4) Spell: Bounce (by Secondary Type, decrementing) Variants: IWD1 IWD2
Parameter #1: Total Amount
Parameter #2: Secondary Type
Description:
The targeted creature(s) will reflect a number of effects (specified by the Total Amount field) whose Secondary Type is equal to the one specified by the Secondary Type field.

If the opcode #177/opcode #283 effect is reflected, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

#231 (0xE7) Spell Effect: Time Stop Variants: IWD1
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Applies the time stop effect.
The timestop effect lasts half as long as the Duration specified for the effect.

In particular:
  • All creatures not immune to Time Stop will be rendered uncontrollable, can be hit automatically by attacks as if they were HELPLESS (but do not actually have STATE_HELPLESS set), and their frequency-based effects will not trigger (poison/regeneration), but their duration will run.
  • Projectiles are suspended mid-flight until the Time Stop ends, at which point they will resume normal function.
  • Area Effect projectiles are suppressed until the Time Stop ends, at which point they will resume normal function, though their duration will run during the Time Stop.
  • Projectiles that hit "instantly" (#0 and #1 for spells/items) are unaffected by Time Stop, which includes all melee weapons.
Important: Both parameters should be 0 (zero).
Note: Only one creature may have a Time Stop effect running at a time, applying a Time Stop effect during another will override the previous. The caster is always immune to their own Time Stop effect, they do not require opcode #310, unless their own Time Stop is at risk of being overridden.

Info:
  • Every STAT from 89 to 134 is a weapon proficiency, even the weapon styles.
  • Every one of those STATs can be set as a weapon's proficiency and it will use that stat's value for proficiency bonuses.
    • This includes STATs like CLERIC_ARMOR_OF_FAITH*, even though they're used for an alternative purpose.
      • The only thing stopping them from showing up during chargen/level-up proficiency selection is their entries (or lack there of) in WEAPPROF.2DA. A NAME_REF column of 4294967296 (-1) is hardcoded to hide the proficiency during chargen/level-up. Aside from that it just needs a non-zero maximum for the current class/kit.
Bug: In EE games, Type 99 – PROFICIENCYHALBERD currently cannot use the Increment option without crashing.
Important: In EE games, the Special field must currently be 0, due to an incomplete (bugged) feature added by Beamdog (it wasn't used before anyway, so there was no point in it not being 0).
Note: The Proficiency Modifier effect cannot increment or decrement proficiency points, it can only SET them.

This is however not true for EEs, where param#2 ('Type') is split into two word subfields. By setting the second (high) one to 1 (Increment), it’s possible to increment/decrement the proficiency points of the targeted creature(s) by the value specified by the Amount parameter.

#234 (0xEA) Spell Effect: Contingency Creation Variants: BGEE IWD1 IWD2
Parameter #1: Maximum Level Usable
Parameter #2: Amount/Type
Description:
Creates a contingency.
The 'Maximum Level' field indicates the maximum spell level that can be used in the contingency. The 'Amount/Type' field indicates the number of spells that can be used in the contingency, and the type of the contingency.
Known values for the 'Amount/Type' field are:
First word: Amount (1-3)
Second word:
0 Chain Contingency
1 Contingency
2 Broken Sequencer
Note: This opcode only works from party-members.

#235 (0xEB) Spell Effect: Wing Buffet Variants: IWD1
Parameter #1: Speed
Parameter #2: Direction
Description:
Applies the wing buffet effect centred on the casting creature(s), buffeting the targeted creature(s) at the speed specified by the Speed field, in the direction specified by the Direction field. Speed ranges from 0 to 255.
Known values for Direction are:
  • 0/1 ⟶ Away from the destination point (specified in EFF file)
  • 2 ⟶ Away from the source
  • 3 ⟶ Towards the destination point (specified in EFF file)
  • 4 ⟶ Towards source
Note: If used on creatures with the “pass-wall” effect applied, creatures can cross points marked as light obstacles on the search map.
In EEs, this effect can push creatures through closed (and locked) doors (this does not require the “pass-wall” effect).
Note: Direction options 1 and 3 “can” be overriden in external EFF files, but default to the ability target/location.
Note: Some animations are immune to this effect.

#236 (0xEC) Spell Effect: Image Projection Variants: IWD1 IWD2
Parameter #1: Undetermined
Parameter #2: Type
Description:
Creates an image (duplicate) of the caster, in the style specified by the Type field.
In particular:
  • The Image inherits any/only effects attached to the creature using Timing Mode 9.
  • The Image has duplicates of all of the targeted creature(s) items that are flagged with DROPPABLE and not flagged with NONDROPABLE.
  • All items on the Image are flagged with NONDROPABLE, so an image created by another image will have no items.
  • If the targeted creature(s) is not a party memeber, saving is disabled so long as the image exists.

Known values for Type are:
  • 0 ⟶ Clone – Image created with the targeted creature(s) Current Hit Points and the following (in order)
    • All AI scripts and Dialogues are set to "" (empty string, i.e. they will be cleared).
    • Script Name (Death Variable) set to "COPY".
    • Opcode #68 based on effect duration.
    • The creature is not immediately controllable, but will become controllable (if allied) after saving & reloading.
  • 1 ⟶ Mislead – Image created with the targeted creature(s) Maximum Hit Points and the following (in order)
    • Allegiance set to ALLY, NEUTRAL, or ENEMY, depending on target allegiance.
    • Gender set to ILLUSIONARY.
    • All AI scripts and Dialogues are set to "" (empty string, i.e. they will be cleared).
    • If the clone's allegiance is not ALLY, Class Script is set to 'Original Class Script' + 'M'. The script has to already exist (as a separate BCS file).
      • And the Class Script is only set if it wasn't originally null/empty – it will never be just "M".
      • If Original Class Script is 8 characters long, the last letter will be replaced with "M".
      • If you look in BG2EE, you will see these files:
        • MAGE18A.BCS -> MAGE18AM.BCS
        • MAGE18B.BCS -> MAGE18BM.BCS
        • MAGE18C.BCS -> MAGE18CM.BCS
        • MAGE18D.BCS -> MAGE18DM.BCS
        The caster uses the first one, their Mislead clone uses the second one.
    • Script Name (Death Variable) set to "COPY".
    • Opcode #68 based on effect duration.
    • Opcode #237*p2=1: Puppet Stats, Mislead

    • Opcode #144*p2=12: Disable Button (Quick Item 3)
    • Opcode #144*p2=13: Disable Button (Special Ability)
    • Applies "MISLEAD.SPL"
  • 2 ⟶ Project Image – Image is created with the targeted creature(s) Current Hit Points and the following (in order)
    • Allegiance set to ALLY, NEUTRAL, or ENEMY, depending on target allegiance.
    • Gender set to ILLUSIONARY.
    • All AI scripts and Dialogues are set to "" (empty string, i.e. they will be cleared).

  • 3 ⟶ Simulacrum – Image is created with the targeted creature(s) Current Hit Points and the following (in order)
    • Allegiance set to ALLY, NEUTRAL, or ENEMY, depending on target allegiance.
    • Gender set to ILLUSIONARY.
    • All AI scripts and Dialogues are set to "" (empty string, i.e. they will be cleared).
    • Script Name (Death Variable) set to "COPY".
    • Opcode #68 based on effect duration.
    • Opcode #216 (amount should be 60% of character level, but doesn't compute dual-classes correctly).
    • Opcode #237*p2=3: Puppet Stats, Simulacrum
    • Applies "SIMULACR.SPL"
  • 4+ ⟶ As 0
Note: Keep in mind that if the caster is equipped with an irremovable item (e.g., Edwin’s Amulet), then its images will not inherit any bonuses/maluses from that specific item.

#237 (0xED) Spell Effect: Puppet ID Variants: IWD1 IWD2
Parameter #1: Master ID
Parameter #2: Image Type
Description:
This effect stores information for images created by opcode #236.

#241 (0xF1) Charm: Control Creature Variants: IWD1
Parameter #1: Creature ID
Parameter #2: Charm Type
Description:
As opcode #5.

#242 (0xF2) Cure: Confusion Variants: BGEE IWD1 IWD2

This effect sets BERSERKSTAGE2 to Constant Value. It also sets the STATE_BERSERK flag.
Important: The Constant Value parameter should be non-zero.
Note: At least in EEs, the only difference between opcodes #3 and #247, is that opcode #247 will not force the creature(s) to use melee weapons, and is not removed by opcode #4 (Cure Berserk).

#248 (0xF8) Item: Set Melee Effect Variants: IWD1 IWD2
Parameter #1: Irrelevant
Parameter #2: Fist only
Description:
Sets the effect specified by the resource key as a melee effect.
The specified effect will be applied to the target of each successful melee attack.
The resource key references a .EFF not a .SPL.

The String Reference field should match opcode #253 StrRef to be removed. Opcode #254 needs to be cast on exact coordinates as opcode #253.

Important: This effect works in SoA but not ToB. Works fine in EE's.

#255 (0xFF) Item: Create Inventory Item (days) Variants: IWD1
Parameter #1: Charges
Parameter #2: Irrelevant
Description:
Creates the item specified by the resource key. The number of items created is controlled by the Charges field. The number of secondary charge is determined by Parameter3. The number of tertiary charges is determined by Parameter4 (external EFFs). The item is created in the Inventory, and has the can not steal bit set.
Note: The difference from opcode #122 is that when used in an external EFF, the duration (from the calling file) is specified in days.

#256 (0x100) Spell: Spell Sequencer Active Variants: BGEE IWD1
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
This effect stores the spell resources for an active spell sequencer. The three spell resources are stored in the resource key, VVC field, and eff 3rd parameter.

The spell which contains the Spell Sequencer Activation effect must have the same filename, suffixed with the D character.
eg:
Spell Sequencer Creation filename = SPSS101
Spell Sequencer Activation filename = SPSS101D

#259 (0x103) Protection: Spell Trap (by Power Level, decrementing) Variants: IWD1 IWD2
Parameter #1: Total Amount
Parameter #2: Power Level
Description:
Applies the spell-trap effect to the targeted creature(s), absorbing a number of effects as specified by the Total Amount field, of the level specified by the Power Level field, and recalling previously cast spells.

The Power level of the first effect to trigger any instance of this opcode's trap will determine how much this opcode's Total Amount is decremented. Every instance of this opcode on the creature will be decremented by this amount.

On EE games, resource field ⟶ Spell cast when this effect self-terminates, default = Parent + "B".

Info:
  • CANNOT trap effects of Secondary Type MagicAttack.
  • CANNOT trap EFF files with resist_dispel = BIT2.
    • Keep in mind that this BIT is automatically set on any effect delivered by an Area-Effect (Explosion) projectile, so this opcode cannot trap effects through AoE projectiles.
  • CANNOT trap effects from self.
  • Maintains portrait icon Spell Trap on the target.
  • Maintains animation SPMAGGLO on the target, can be suppressed by opcode #291.
  • When it traps an effect, it applies opcode #261 to the target.
    • Parameter1 is the Power level of the trapped effect, Parameter2 is always 0|Wizard.
Note: EFF files delivered by opcode #177/opcode #283 will interact with Trapping separately from the opcode #177/opcode #283 effect that applies them, and only if that opcode #177/opcode #283 effect already got through. If the opcode #177/opcode #283 effect is trapped, then the values in the EFF file won’t matter. Most vanilla EFF files have these fields set to empty/zero to avoid interacting with this opcode.

Info:
  • On non-EE games, this effect does not have proper bounds checking. It can therefore be used in unintended ways. For example scripting state 13 equals with the NO_CIRCLE attribute (stat=169), and scripting state 1139 ties to PICKPOCKET (stat=29).
  • EEs have proper bounds checking for this opcode, can only modify stats #156 – #200, except SUMMON_DISABLE_ACTION, not all values are a straight "subtract 156 from their stat".
    • For best results, it should only be used for stats #156 – #165, as all others have dedicated opcodes and hardcoded effects.

The targeted creature(s) will still run scripts when off-screen and out of combat.

The effect modifies PREVENT_AI_SLOWDOWN to Stat Value.

  • However, creatures without this opcode attached will run scripts at a considerably slower rate (about ⅓ or ¼ rate).
  • Moreover, it looks like off-screen creatures move only at halved speed (which might be true for other actions as well). With this opcode creatures seem to move and act at the same speed as on-screen.

Known values for Type are:
  • 0 ⟶ Set Local (to Value)
  • 1 ⟶ Increment Local (by Value)
Info:
  • Since the resource key can only be 8 characters long maximum, you can not set a variable with this Effect that has a name longer than this amount.
    • You can use the Resource 2 field of external EFF files for an additional 8 characters of variable name.
      • You can use the Resource 3 field of external EFF files for an additional 8 characters of variable name.
        • As a result, it cannot modify variables more than 24 characters long.

#312 (0x138) Crash Variants: BGEE
Parameter #1: Undefined
Parameter #2: Undefined
Description:
This effect crashes the game.

#313 (0x139) High-Level Ability Denotation
Parameter #1: Undetermined
Parameter #2: Undetermined
Description:
This effect denotes that the high level ability specified by the resource key has been gained. Used for pre-requisites/count limits.
Info: Automatically applied by the engine when selecting HLAs, but can be manually applied for the same effect.

#314 (0x13A) Spell: Golem Stoneskin
Parameter #1: Amount
Parameter #2: Irrelevant
Description:
Gives the targeted creature(s) a number of protections from physical attacks, as specified by the Amount field.
This opcode maintains STONESKINSGOLEM to the amount of skins left.
Warning: Do not use this effect in conjunction with the Juggernaut Golem Manual as it will corrupt the use of that item.
In particular, the Juggernaut Golem "TOMEGOL4.CRE" is scripted by "TOMEGOL4.BCS" to Kill() itself if its Summoner and no Party Members have STONESKINSGOLEM set to a non-zero value.

#315 (0x13B) Graphics: Animation Removal
Parameter #1: Irrelevant
Parameter #2: Stat Value
Description:
This effect will remove the animation of the targeted creature(s).

The effect modifies STAT #201 to Stat Value.
Note: The Stat Value parameter can take any value. If you set it to 0, you will disable the effect (for its duration).

#316 (0x13C) Spell: Magical Rest
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
This effect will refresh spells and remove any fatigue.

#317 (0x13D) State: Haste 2
Parameter #1: Irrelevant
Parameter #2: Type
Description:
This effect is functionally identical to opcode #16. The only difference between the two is that some ITMs/SPLs/abilities will specifically block/remove opcode #16 but not opcode #317 (e.g., Monks are immune to opcode #16 but not opcode #317).

#318 (0x13E) Stat: Set Stat (TobEx) Variants: BGEE
Parameter #1: Statistic Modifier
Parameter #2: Stat Opcode (low word) / Type (high word)
Description:
Applies the modifier value specified by the 'Statistic Modifier' field in the style specified by the 'Type' field to the opcode specified by the 'Stat Opcode' field.
Known values for 'Type' are:
0 Cumulative Modifier -> Value = Value + 'Statistic Modifier' value
1 Flat Value Modifier -> Value = 'Statistic Modifier' value
2 Percentage Modifier -> Value = (Value * 'Statistic Modifier' value) / 100
3 Multiplicative Modifier -> Value = Value * 'Statistic Modifier' value
4 Divisive Modifier -> Value = Value / 'Statistic Modifier' value
5 Modulus Modifier -> Value = Value % 'Statistic Modifier' value
6 Logical AND Modifier -> Value = Value && 'Statistic Modifier' value
7 Logical OR Modifier -> Value = Value || 'Statistic Modifier' value
8 Bitwise AND Modifier -> Value = Value & 'Statistic Modifier' value
9 Bitwise OR Modifier -> Value = Value | 'Statistic Modifier' value
10 Inverse Modifier -> Value = !Value

You cannot set any stats with opcode < 387 with this effect. New stats 202-400 are reserved for new hard-coded stats.
Important: ONLY available if TobEx is installed!
