After the header rows (2DA V1.0, *, STATE, STRREF, 1, 2, etc...), each row represents a parameter2 value for opcode #335 starting at 0, but the file still functions without opcode #335, it does not care how the spellstate gets set, only that it is set.

• Column 0 is an arbitrary label – has no real function, can be duplicate.
• Column 1 is the spellstate that must be set to activate this row.
• Column 2 is the string reference (dialog.tlk) that will be displayed when the row triggers (for each effect it triggers on).

While the row is active (i.e., the spellstate is set), all effects it blocks will instead trigger the STRREF feedback message, and do nothing else.
Later columns list a mix of 4 possible values to represent the effects it will block:

• *: (placeholder/nothing) some 2DA files need filled columns, so empty columns use one of these.
• RESREF: file resource (SPWI605 SPWI713 SPWI912 SPPR511 SPPR734 etc...) – blocks all effects from that resource.
• integer: opcode (38 45 74 80 109 etc...) – blocks all effects of that opcode, but not those attached through opcode #177 (or opcode #283)
• integer*value: opcode + 'parameter2' value (12*0x200000) (damage – poison); value can be integer or hexadecimal format. Blocks all effects of both that opcode and parameter2 value, but not those attached through opcode #177 (or opcode #283).

In IWD:EE we have:
