IWD1 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.

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’ as a damage type will result the game to crash if the damage kills the target.

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 -> Dexterity = 'Statistic Modifier' value
2 Percentage Modifier -> Dexterity = (Dexterity * 'Statistic Modifier' value) / 100
3 Cat's Grace Spell ('Statistic Modifier' should be set to 0)

Info: This effect will cancel out the slow opcode.

#17 (0x11) HP: Current HP Modifier Variants: BG2 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: 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.
Info: If ‘Statistic Modifier’ and the Dice values are both non-zero, the total HP change is: ‘Statistic Modifier’ + Dice value.
Note: 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: 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.

2 Percentage Modifier -> Intelligence = (Intelligence * 'Statistic Modifier' value) / 100

'Statistic Modifier' can be positive or negative.

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 -> affected creature makes the first attack with +4
1 Improved Invisibility -> affected creature stays invisible after attack
2 Toggle Invisibility -> affected creature invisibility state toggles when executing an action
Note: ‘Improved Invisibility’ does not provide saving throw bonuses.
Note: ‘Improved Invisibility’ lingers after the duration is spent and works permanently if used as a ‘While Equipped’ effect.

#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

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

#22 (0x16) Stat: Cumulative Luck Bonus 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. 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: BG2
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.

  • 1 ⟶ Flat Value Modifier: Morale = 'Statistic Modifier' value
  • 2 ⟶ Percentage Modifier: Morale = (Morale * 'Statistic Modifier' value) / 100

Statistic Modifier can be positive or negative.

At least in EEs, known values for Mode are:
  • 0 ⟶ BG2 mode – It's hardcoded to fill the following values:
    • Statistic Modifier = 10
    • Type = 1
    • m_done = 1 (internal field that immediately removes the effect from creature, no matter duration)
    • In addition, it checks if the creature is berserking, and if it is, it returns without doing anything.
  • 1 ⟶ BG1 mode – Default (functions as expected)
Note: Any Morale-based effect (i.e. Panic) may be added or removed by this effect.

#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)

  • 0 ⟶ Cumulative Modifier: Save = Save + 'Statistic Modifier' value
  • 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.
Bug: Since at least version 2.5, Type = 3 modifies instantly SAVEVSWANDS instead of SAVEVSDEATH.
As a result, saving throws for effects in the same effect stack and after this opcode are not processed as expected.
Effects proceeded after the stack are treated normaly like Type = 0.

Statistic Modifier can be positive or negative.

The effect modifies SAVEVSSPELL.
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), bard song 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. If it is set, also spell state PRONE will be set. Otherwise the creature will be moved to the backlist and become untargettable by most scripts.

This opcode sets the STATE_SLEEPING and STATE_HELPLESS flag bits.

Note: In case of Timing Modes 1/4/7 the bits cannot be removed in-game.
Moreover, the STATE_SLEEPING works as the Wake on Hit option. It’s just not usable because of the unremovable STATE_HELPLESS.
Note: Immunity to this opcode does not prevent unconsciousness from stunning damage done by normal fists.

#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 IWD2 PST PSTEE BG2
Parameter #1: Colour
Parameter #2: Type
Description:
Displays the sparkle effect specified by the 'Type' field, in the colour specified by the 'Colour' field.
Known values for 'Colour' are:
0 Crash
1 No effect / Black
2 White / White -> Blue
3 Purple -> White / Purple -> White

13 Crash
Known values for 'Type' are:
1 Sparkle Puff
2 No effect?
3 Sparkle Shower

#42 (0x2A) Spell: Wizard Spell Slots Modifier Variants: BG1
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
    • The amount of spell slots is doubled for the level specified by the Slot Amount Modifier value and all levels below
  • BIT0 ⟶ Level 1
  • BIT1 ⟶ Level 2
  • BIT2 ⟶ Level 3
  • BIT3 ⟶ Level 4
  • BIT4 ⟶ Level 5
  • BIT5 ⟶ Level 6
  • BIT6 ⟶ Level 7
  • BIT7 ⟶ Level 8
  • BIT8 ⟶ Level 9
  • BIT9 ⟶ Double spells
    • The amount of spell slots is doubled exclusively for the level specified by Slot Amount Modifier

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: IWD2 PST 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:

1 Flat Value Modifier -> Strength = 'Statistic Modifier' value
2 Percentage Modifier -> Strength = (Strength * 'Statistic Modifier' value) / 100
3 Strength Spell ('Statistic Modifier' should be set to 0)

Negative values for 'Statistic Modifier' act as follows for the 'Type' modes:
0 Strength = Strength - 'Statistic Modifier' value
1 Strength = 25
2 Strength = 25

#45 (0x2D) State: Stun Variants: BG1
Parameter #1: Irrelevant
Parameter #2: Type
Description:
Stuns the targeted creature(s) in the style specified by the 'Type' field.

#47 (0x2F) Cure: Invisibility
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Removes the invisibility effect from the targeted creature(s) if they don't have STATE_NONDETECTION set. Also removes STATE_INVISIBLE and STATE_IMPROVEDINVISIBILITY.
This effect ignores durations attributed to it.
Important: Both parameters should be 0 (zero).

#48 (0x30) Cure: Silence (Vocalize)
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:

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

Negative values for 'Statistic Modifier' act as follows for the 'Type' modes:
0 Wisdom = Wisdom - 'Statistic Modifier' value
1 Wisdom = 25
2 Wisdom = 25

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

#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: BG2 BG1
Parameter #1: Percent Chance

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. For a 'Spell Level' of 512, the amount of spell slots is doubled for the level(s) specified by the 'Slot Amount Modifier' field. The target creature(s) must have at least 1 slot at the selected level to have their slot count changed. If the resultant slot count is negative, the creature is given 12 slots.

'Statistic Modifier' can be positive or negative.

#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: PST BG1
Parameter #1: Fade speed
Parameter #2: Type
Description:
Fades the targeted creature(s) in or out. The 'Fade speed' field controls how fast it happens.

#67 (0x43) Summon: Creature Summoning Variants: IWD2 PST
Parameter #1: Irrelevant
Parameter #2: Mode
Description:
Summons a creature, with position and EA based on the Mode field. The Resource key should be set to the filename of the creature to summon.
Known values for Mode are:
Mode Position EA
0, 1 effect align with target creature
3 target creature align with target creature
4 target creature CRE file
5 effect align against target creature
2, else effect CRE file
Info: Mode details:
  • Position:
    • 3, 4 ⟶ summon at target creature's position
    • else ⟶ summon at effect position
  • EA:
    • 0, 1, 3 ⟶ align with target creature:
      • target creature EA ≤ GOODCUTOFF (30) ⟶ summon as ALLY (4)
      • target creature EA ≥ EVILCUTOFF (200) ⟶ summon as ENEMY (255)
      • else ⟶ summon as CRE file
    • 5 ⟶ align against target:
      • target creature EA ≤ GOODCUTOFF (30) ⟶ summon as ENEMY (255)
      • target creature EA ≥ EVILCUTOFF (200) ⟶ summon as ALLY (4)
      • else ⟶ summon as CRE file
Bug: Mode = 5 fails to make creatures summoned as ALLY (4) controllable. This is fixed upon reload.
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) Damage Mod Variants: BG1
Parameter #1: Damage Modifier
Parameter #2: Type
Description:
Inflicts a percentage extra damage (set by the 'Damage Modifier' parameter) of the type specified by the 'Type' parameter.
Known values for 'Type' are:
0 Standard
1 Fire
2 Cold
3 Electricity
4 Acid
5 Magic
6 Poison
7 Slashing
8 Piercing
9 Crushing
10 Missile
Note: ‘Type’ 0 causes a flat damage increase, rather than a percentage.

#74 (0x4A) State: Blindness Variants: BG1
Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
Applies the blindness effect to the targeted creature(s). This sets VISUALRANGE to 2, sets STATE_BLIND to true and incurs a cummulative 10 point base THAC0 penalty (4 on EE games, plus a cumulative 4 point base AC penalty. All of that is unverified in PST). Maintains its own portrait icon Blind.
Important:
  • Timing Modes 1/4/7 will permanently set the creature's STATE_BLIND flag, leaving no removable effect.
  • Related: the -4 penalty to AC and THAC0 are apparently tied to the effect, not STATE_BLIND.
    • So for instance you will not be able to 100% cure a creature affected by CLERIC_NATURE_BEAUTY — "sppr704.spl" (it applies opcode #74 with timing_mode=1).
      • As a workaround, you might want to stick with a limited timing_mode and set duration to a very high random value.
Note: In the EE’s, the -4 penalties it applies are not cumulative.

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.

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 ⟶ Party Reputation = 'Statistic Modifier' value, cannot lower reputation below 100, will raise reputation to 100 if already less (only in EEs)

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.
Important: The Magical Weapon Slot does not allow Item Abilities.
Warning: The resource field should not be empty, or the game will crash (not consistently, but it happens).
Info: The dispel bit of opcode #111 has no bearing on the item it creates. Its only function comes up when the opcode #111 effect is delayed — the effect can be dispelled before it triggers (see also undispellable and opcode #58).

#112 (0x70) Item: Remove Item Variants: BGEE
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

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

  • 8 ⟶ Cursed
  • 9 ⟶ Non-Cursed
  • 10 ⟶ Cold Iron
  • 11 ⟶ Non Cold Iron
Info: Keep in mind that:
  • 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.
  • 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)".

  • 2 ⟶ Non-stacking Percentage Modifier: Movement = (Movement * 'Statistic Modifier' value) / 100
  • 5 ⟶ Multiplicative Stacking Percentage Modifier: Movement = (Movement * 'Statistic Modifier' value) / 100 (EE only)
Note: BG1 does not support the cumulative modifier and will behave as if in flat modifier mode.
Info: A couple of examples about Multiplicative Stacking Percentage Modifier:
  • 50% * 50% = 25%
  • 150% * 150% = 225%

When used in SPL/ITM files, known value for Mode are:
When used in external EFF files, known value for Mode are:
The Type field sets which 2DA file to pick the creatures to summon from. The 2da files are monsumX and anisumX, where X = 'Type' + 1. 0–4 are allied , 5–9 are hostile. The specific 2da files used are:
  • 0 ⟶ MONSUM01: Monster Summon 1
  • 1 ⟶ MONSUM02: Monster Summon 2
  • 2 ⟶ MONSUM03: Monster Summon 3
  • 3 ⟶ ANISUM01: Animal Summon 1

Important: Timing Mode 1 will set STATE_CONFUSED without leaving behind a removable effect.
Info: STATE_CONFUSED specs:

#129 (0x81) State: Aid Variants: PST
Parameter #1: Statistic Modifier
Parameter #2: Irrelevant
Description:
Applies a bless effect to the targeted creature(s).
In particular:
  • Grants a bonus/penalty to all Saving Throws equal to Statistic Modifier.
  • Grants a bonus/penalty to Current and Maximum Hit Points equal to 'Statistic Modifier'd8.
  • Grants a bonus/penalty to base THAC0 equal to Statistic Modifier.
  • Grants a bonus/penalty to base weapon damage equal to Statistic Modifier.
  • Saving throws, THAC0, and Damage modifiers read only the first byte of Statistic Modifier for their value, the last 3 bytes are ignored.
  • HP modifier uses the whole 4 bytes of Statistic Modifier.
  • HP modifier is always positive (negative values become zero), but because Max HP itself is not bounded, it can overflow into negative amounts (Max HP is 32767).
  • When used in external EFFs, Parameter2 controls the exact amount of HP gained.
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.
Testing in the original BG2 shows that if this opcode is used on an item with “while equipped” duration, it becomes “permanent” when the item is equiped. Meaning that one can equip/unequip the item multiple times to give more and more eg. maximum hitpoints.

  • The oldest non-equipped effect will override newer non-equipped effects.
Note: Modifier only reads the first byte for its value, the last 3 bytes are ignored.

#146 (0x92) Spell: Cast Spell (at Creature) Variants: IWD2 PST
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 at specified level (0 for caster level), non-interruptible
  • 1 ⟶ Cast Instantly at caster level
  • 2 ⟶ Cast Instantly at specified level (EE-only)
Important:
  • When this opcode gets reflected using Type=1, the spell specified by the resource key is cast at the target's Casting Level, not the caster's.
  • When this opcode gets reflected (opcode #197, opcode #198, opcode #199, opcode #202, opcode #203 and opcode #207) using Type=2, the spell specified by the resource key is cast at the specified Casting Level, and it will also affect the original target (as if it wasn't reflected).
Note:
  • When Type=2, effects in the resource will also bypass Magic Resistance, of every target, as if the caster targeted themselves, regardless of who they target with the spell or this effect.
    • 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.

Description:

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.

Parameter #2: Undefined

  • This effect removes the creature from the player's party (if they were in it).
  • The effect will keep the creature out of the party and any other Area for its duration, but does not re-instate the creature once it expires.
  • They can still be recovered through script actions once the effect expires.
Important: Both parameters should be 0 (zero).

#170 (0xAA) Graphics: Play Damage Animation Variants: PST
Parameter #1: Irrelevant
Parameter #2: Animation
Description:
Plays the damage animation specified by the Animation field.
It just plays a visual effect, like a far more limited version of opcode #215, and is always instantaneous.
Known values for Animation are:
  • 0 ⟶ Blood (behind)
    • (EEs) Doesn't display any animation.
  • 1 ⟶ "BLOODS.BAM" Blood (small)
  • 2 ⟶ "BLOODM.BAM" Blood (medium)
  • 3 ⟶ "BLOODL.BAM" Blood (large)
  • 4 ⟶ "SPFIRIMP.BAM" Fire 1
  • 5 ⟶ "SPFIRIMP.BAM" Fire 2
  • 6 ⟶ "SPFIRIMP.BAM" Fire 2
  • 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.

#171 (0xAB) Spell: Give Ability Variants: PST

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:

#182 (0xB6) Item: Apply Effect Item Variants: BGEE
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 EFF file specified by the resource key to the targeted creature(s) when an ITM of the item type specified by the Type field is equipped.
Important: EFF files applied by this opcode bypass / ignore opcode #101.
Note:
  • Ammo (i.e., Arrows, Bullets and Bolts) does not work well with this opcode
    • The Ammo Slots (SLOT_AMMO, SLOT_AMMO1, SLOT_AMMO2, SLOT_AMMO3) 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
        • Having said that, this opcode currently allows detecting a launcher using its automated ammo (such as Shortbow of Gesen)
  • The offhand (SLOT_SHIELD) has the same issue — even when disabled, it's detected by this opcode as equipped
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: PST BG2
Parameter #1: Value
Parameter #2: Irrelevant
Description:
This effect stores a local variable, specified by the 'variable' field. This effect can only be used in an external effect (ie. an eff file).
Note: At minimum in later engines, this opcode can also store other values. Check the doc for BG2.

#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: BG2 BGEE 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
Note: This effect changes the casting level stat, but has no actual affect in-game IWD1

Parameter #1: Irrelevant
Parameter #2: Irrelevant
Description:
This opcode has no effect.

#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) Empty: Variants: IWD2 PST BG2
Parameter #1: Irrelevant
Parameter #2: Irrelevant

#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.
