PST 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:

Type=0:
- Modifies ARMORCLASS.
- With Timing Modes 1/4/7, alters target's base Armor Class.
Type=1:
- Modifies ACCRUSHINGMOD.
- With Timing Modes 1/4/7, alters target's base Crushing AC.
Type=2:
- Modifies ACMISSILEMOD.
- With Timing Modes 1/4/7, alters target's base Missile AC.
Type=4:
- Modifies ACPIERCINGMOD.
- With Timing Modes 1/4/7, alters target's base Piercing AC.
Type=8:
- Modifies ACSLASHINGMOD.
- With Timing Modes 1/4/7, alters target's base Slashing AC.
Type=16:
- Modifies ARMORCLASS.
- With Timing Modes 1/4/7, alters target's base Armor Class, still subject to "only if better/lower", checked against base value, not current effective value.

#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 and sets BERSERKSTAGE2 to 1.
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.

Parameter #1: General Type
Parameter #2: Charm Type

Description:

Charms the targeted creature(s) according to value in the 'Charm Type' field, if the target is matched by the value in the 'General Type' field. Values for 'General Type' are from General.ids.

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.
- Index 4–15: Grey
- Index 16–27: Cyan
- Index 28–39: Pink
- Index 40–51: Yellow
- Index 52–63: Red
- Index 64–75: Blue
- Index 76–87: Green
  (7 groups of 12 indexes, each exclusive to one location)
- Index 88–95: (Grey + Cyan)
- Index 96–103: (Grey + Magenta)
- Index 104–111: (Grey + Yellow)
- Index 112–119: (Grey + Red)
- Index 120–127: (Grey + Blue)
- Index 128–135: (Grey + Green)
- Index 136–143: (Cyan + Magenta)

#8 (0x8) Colour: Colour Glow Solid Variants: BG1 IWD1 BG2
Parameter #1: RGB Colour
Parameter #2: Irrelevant

Description:

Set the RGB Colour parameter to the colour value you want to use with the second byte being the Red portion (0-255), the third byte the Green portion (0-255), and the fourth byte being the Blue portion (0-255).

#9 (0x9) Colour: Colour Glow Pulsate Variants: BG1 IWD1 BG2
Parameter #1: RGB Colour
Parameter #2: Pulse Speed

Description:

Set the RGB Colour parameter to the colour value you want to use with the second byte being the Red portion (0-255), the third byte the Green portion (0-255), and the fourth byte being the Blue portion (0-255) and the part specified by the third byte of the Speed parameter determining the speed of the flashing with 01 the fastest and 255 the slowest. A speed parameter of 0 does not pulsate. If the colour values are all set to 0, the glow effect only occurs if the creature is in darkness; outside at night, inside a building, or standing in shadows.

#10 (0xA) Stat: Constitution Modifier Variants: IWD1 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 -> Constitution = Constitution + 'Statistic Modifier' value
1 Flat Value Modifier -> Constitution = 'Statistic Modifier' value
2 Percentage Modifier -> Constitution = (Constitution * 'Statistic Modifier' value) / 100

'Statistic Modifier' can be positive or negative.

#11 (0xB) Cure: Poison
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

Removes opcode #25 poison effects and STATE_POISONED from the targeted creature(s).

Info: This effect ignores durations attributed to it.

Info: At least in EEs, this effect can remove opcode #177 effects targeting an EFF with opcode #25.

#12 (0xC) Damage Variants: BG2 BGEE BG1
Parameter #1: Fixed Damage
Parameter #2: Damage Type

Description:

Set the Dice Throws and Size to the random damage you wish to do to the target (if you want no random damage done, leave it at 0d0). If you wish to do fixed damage as well, or by itself, set the Fixed Damage parameter to the ammount of damage to do (if you want no fixed damage done, leave the value at 0).
If a saving throw is made, the damage values are cut in half, including Fixed Damage. To completely negate damage in the case of a successful saving throw, set the Resource Key to NEG.
The following values are valid for Damage Type:
0 is Crushing Damage
1 is Lower HP to Fixed Damage value(Ignores random damage values)
2 is Lower HP to Fixed Percent set by Fixed Damage value
4 is Lower HP by 1/3 of the effect's damage (after random damage has been rolled)
65536 is Acid Damage
131072 is Cold Damage
262144 is Electic Damage
524288 is Fire Damage

33554432 is Magic Fire Damage
67108864 is Magic Cold Damage
134217728 is Stunning Damage
The opcode uses the 'variable' field at 0x2c to determine which (if any) custom critical damage visual to play. Known values are:
0x01 - The Nameless One
0x02 - Annah
0x04 - Grace
0x08 - Nordom
0x10 - Vhailor
0x20 - Morte
0x40 - Dakkon
0x80 - Ignus

Important: Keep in mind that if a character makes a save for damage type 1 or 2 without the NEG Resource Key, the Fixed Damage will be cut in half, which will cause MORE HP loss!

Info: ‘Stunning’ damage does not stun the target. Stunning damage cannot kill a creature, creatures are reduced to 1 HP and are knocked unconscious.

#13 (0xD) Death Variants: BG1 IWD1 BG2
Parameter #1: Irrelevant
Parameter #2: Death State?

Description:

This effect will instantly kill a creature. Leave both parameters at zero for this effect to work.

Warning: DO NOT use a timing mode of Duration or Permanent for this effect, or it will crash! To use this effect without a delay, simply set the timing mode to Delay, and the time to 0.

The Death State? parameter sets whether or not the CGAMESPRITE_STATE_DEAD is applied to the target:
0 or any multiple of 4 (4,8,16,32...)-State set in target
Any other-Target simply killed.

#14 (0xE) Defrost Variants: BG1
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

Removes the frozen_death state.

#15 (0xF) Stat: Dexterity Modifier Variants: IWD1 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 -> Dexterity = Dexterity + 'Statistic Modifier' value
1 Flat Value Modifier -> Dexterity = 'Statistic Modifier' value
2 Percentage Modifier -> Dexterity = (Dexterity * 'Statistic Modifier' value) / 100

'Statistic Modifier' can be positive or negative.

#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.
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.

#20 (0x14) Invisibility (state) Variants: BG1 IWD1 IWD2 BG2
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

Leave both parameters at all zeros for this Effect to work.

Warning: This effect will not work with a timing mode of Duration or Permanent. All other timing modes function correctly.

#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: 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, ⁷⁄₁₅ths of a second).
- Luck = "-7": Worst roll possible is a 7, you will be waiting for 1 AI update (or, if you prefer, ¹⁄₁₅th 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:

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.

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:

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.

#34 (0x22) Stat: Save vs. Wands Modifier Variants: IWD2
Parameter #1: Statistic Modifier
Parameter #2: Type

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 SAVEVSPOLY.

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.

#36 (0x24) Stat: Save vs. Breath Weapons 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.

#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) Unconsciousness (Helpless) Variants: IWD2 BG1
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

Leave both parameters at all zeros for this Effect to work. If the Timing Mode is set to 'Duration' or 'Delayed With Duration' (Timing Mode 3), then the target is considered unconscious, and a special graphic effect will appear on the target(s). All other durations simply set 'helplessness'.

#41 (0x29) Graphics: Sparkle Variants: BG1 IWD1 IWD2 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. The colour field may be connected to sprkclr.2da.
Known values for 'Colour' are:
0 Crash
1 Nothing
2 White with small blue specs that alternate between white and dark blue
3 Mostly purple, changing to white towards the end of the effect
4 White sparkles that fade out
5 White sparkles that fade out, but last longer than '4'
6 White sparkles that alternate to purple at the end of the effect
7 Like six, except it seems to change faster
8 Glittering white specs
9 White and grey specs that alternate to blue at the end of the effect
10 Dark grey specs that alternate to white at the end of the effect
11 Pink specs, some changing to white at the end of the effect
12 White effects that very slowly fade out
13 Crash

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

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: BGEE
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

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 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 -> Strength = Strength + 'Statistic Modifier' value
1 Flat Value Modifier -> Strength = 'Statistic Modifier' value
2 Percentage Modifier -> Strength = (Strength * 'Statistic Modifier' value) / 100

'Statistic Modifier' can be positive or negative.

#45 (0x2D) State: Stun Variants: IWD1
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

Stuns the targeted creature(s) and sets HELD to 1. 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) Unstun Variants: BG1
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

This effect will make the target not stunned anymore. Cannot affect targets stunned by 'Set Status Effect(s)'.

Important: Leave both parameters to zero for this effect to function.

#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:

Removes the silence effect and STATE_SILENCED from the targeted creature(s).
This effect ignores durations attributed to it.

#49 (0x31) Stat: Wisdom Modifier Variants: IWD1 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 -> 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.

#50 (0x32) Character Colourglow (Timed) Variants: BG1 IWD1 IWD2 BG2
Parameter #1: RGB Colour
Parameter #2: Timing

Description:

Set the RGB Colour parameter to the colour value you want to use with the second byte being the Red portion (0-255), the third byte the Green portion (0-255), and the fourth byte being the Blue portion (0-255). The third byte of the Timing parameter determines how long the effect takes to reach fully colourization, outside of duration, after which it immediately ends. Valid values are 1-200 for this parameter, with 1 being the fastest.

#52 (0x34) Character Colourglow (Instant II) Variants: BG1 IWD1 IWD2 BG2
Parameter #1: RGB Colour
Parameter #2: Irrelevant

Description:

Set the RGB Colour parameter to the colour value you want to use with the second byte being the Red portion (0-255), the third byte the Green portion (0-255), and the fourth byte being the Blue portion (0-255).

#53 (0x35) Animation ID Modifier Variants: IWD1 IWD2 BG1
Parameter #1: Animation Set
Parameter #2: Irrelevant

Description:

This effect polymorphs the target into a specific creature animation set (i.e. you can change Vhailor into Annah, if you wished, etc). To figure out the Animate Set parameter value, do the following:
Look up the value for the Animation Set you wish to use for this effect in the RESDATA.INI file (it'll be the number in the brackets directly above it), then do the following:
If you want the animation to be falsely/'clown' coloured, add 24576
If you want the animation to be true coloured, add 57344

Warning: There are several animations that SHOULD NOT be used with this effect. They are special, and will result in a CRASH!
Iron Golem
Pillar of Skulls
Foundry Gears
Mortuary Ghost

#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) Kill Creature Type Variants: BG1
Parameter #1: Index Number
Parameter #2: IDS File

Description:

This item will kill the type of creature set by the parameters. The IDS file is the filen to get the reference number from. The Reference number is the creature type to kill.

34 True Neutral
35 Neutral Evil
49 Chaotic Good

#58 (0x3A) Cure: Dispellable Effects (Dispel Magic) Variants: BGEE
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 IWD1
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.

#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
- 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
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).

#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) Transparency Fade Variants: IWD1 BG1
Parameter #1: Fade Amount
Parameter #2: Irrelevant

Description:

Set the Fade Amount parameter to set how faded the Effect does. A 1 is fully visible and a 255 is nearly invisible.

#67 (0x43) Creature Summoning (Ally) Variants: IWD2 BG1
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

Leave both parameters at zero and the duration to 'permanent' for this effect to work. The resource key must be set to the name of the file you wish to use. Creatures summoned in this manner are in full control of the party.

Important: This effect REQUIRES a Bam file named SPBOOM in a bif or the override folder for this effect to work. Without it, the effect WILL NOT WORK.

#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) End Non-Detection Variants: IWD2 BG1
Parameter #1: Undefined
Parameter #2: Undefined

Description:

The exact definitions of these parameter and exact functions are undefined at this time.

#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 (0x6000 ⟷ 0x6010).
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) AI Identifier Modifier Variants: BG1 IWD2 BG2
Parameter #1: IDS Value
Parameter #2: Identifier Type

Description:

Set the Identifier Type to the Object Identifier you wish to alter in the given creature. The IDS Value is the value from the associated IDS file.

0 Allegiance (EA.IDS)
1 General (GENERAL.IDS)
2 Race (RACE.IDS)
3 Class (CLASS.IDS)
4 Specific (SPECIFIC.IDS)
5 Gender (GENDER.IDS)
6 Alignment (ALIGNMEN.IDS)

#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.

Note: PST treats all Type values above 1 as 1 – it does not support the percentage modifier.

#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.

#79 (0x4F) Cure: Disease
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

Removes the disease and feeblemind effects from the targeted creature(s).
This effect ignores durations attributed to it. It also unsets the feeblemind state bit.

Important: Both parameters should be 0 (zero).

#80 (0x50) State: Deafness Variants: IWD2
Parameter #1: Irrelevant
Parameter #2: Irrelevant

9 ⟶ KIT.IDS (EE only; broken at least in 2.5)

To be protected from any creature, leave IDS Entry at 0 (zero), and IDS File at 2. Protection will grant the bearer immunity from being attacked, cast a spell at, or otherwise targeted by creatures with this type.

#101 (0x65) Protection: from Opcode
Parameter #1: Irrelevant
Parameter #2: Opcode

Description:

Gives the targeted creature(s) protection from the opcode specified by the Opcode field.

#102 (0x66) Spell: Immunity (by Power Level)
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.
- V1 effects inherit their Secondary Type from the Header(SPL) / Extended Header(ITM), V2 effects specify it manually.
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.
- V1 effects inherit their non-hostile behavior from the Header(SPL) / Extended Header(ITM), V2 effects specify it manually.

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

Description:

Alters the name of the targeted creature(s) to the strref specified by the String Reference field. When used with a duration timing, after the duration, the name will be set to a blank entry.

#105 (0x69) Stat: Gold Variants: BG2
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.

0 ⟶ Cumulative Modifier: Gold = Gold + 'Statistic Modifier' value
1 ⟶ Flat Value Modifier: Gold = 'Statistic Modifier' value
2 ⟶ Percentage Modifier: Gold = (Gold * 'Statistic Modifier' value) / 100

The effect modifies party gold or GOLD for everyone else.

Note: Type=0 can only remove gold. Gold amount has a lower bound of 0.

Note: PST does not support the percentage modifier type (unknown what it actually does).

#108 (0x6C) Stat: Reputation
Parameter #1: Statistic Modifier
Parameter #2: Type

Description:

Sets the individual reputation of the targeted creature(s) to the value specified by the Statistic Modifier field in the style specified by the Type field.
This does not affect the main reputation of the Party, unless Type 3-5 are used. Though it can affect ranger/paladinhood of any target.
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)
5 ⟶ Party Reputation = (Party Reputation * 'Statistic Modifier' value) / 100, cannot lower reputation below 100, will raise reputation to 100 if already less (only in EEs)

7 Weak
8 Walk
Other values for 'Type' act as 'Run Away'

#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) Item: (Equip Weapon) Variants: BG2
Parameter #1: Undefined
Parameter #2: Undefined

Description:

The use of this effect is unknown, and effect of its parameters are undefined.

#114 (0x72) Graphics: Dither Variants: IWD1
Parameter #1: Undefined
Parameter #2: Undefined

Description:

Sets IDENTIFYMODE to 1.

Description:

Detects the alignment specified by the Alignment Mask field.
Known values for Alignment Mask are:

0 ⟶ Evil (glow Red)

#116 (0x74) State: Cure Invisibility
Parameter #1: 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: Clairvoyance Variants: BG1
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

Applies the clairvoyance effect to the targeted creature(s).

Important: Both parameters should be 0 (zero).

#118 (0x76) Detect: (Show Creatures) Variants: BG2
Parameter #1: Undefined
Parameter #2: Undefined

Description:

The use of this effect is unknown, and effect of its parameters are undefined.

Warning: This effect has never been seen to work.

#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.

7 ⟶ One-Handed
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)".

Note: It is still processed, so it will still interact with Spell Turning/Deflection/etc… just like any other effect.

#122 (0x7A) Item: Create Inventory Item Variants: BG1 IWD2
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.

Info:

(EE only) Resource 2 and Resource 3 (external EFFs): item to be created is randomly chosen from resource fields 1–3 that are not empty.
Applies a delayed opcode #123 effect to remove the item (based on specified duration)

#123 (0x7B) Item: Remove Inventory Item
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

Removes the item specified by the resource key from the targeted creature(s). This effect should be used to remove inventory items (use opcode #112 for equipped items).
In particular:

Removes all item(s) in the first slot containing the specified resource key from the targeted creature(s).
Items in container items (e.g. Bags of Holding) will not be removed.
Inventory slots are checked in numerical order from SLOTS.IDS.

#124 (0x7C) Teleport to a Given Point Variants: IWD1 BG1
Parameter #1: Irrelevant
Parameter #2: Irrelevant

Description:

Important: It is automatically successful but only works on locks that can normally be picked with the Open Locks skill.

#126 (0x7E) Walk/Run Distance Modifier Variants: BG1
Parameter #1: Distance
Parameter #2: Irrelevant

Description:

This alters how far the targets move when walking or running. The effect is somewhat random in appearance though. Set the Distance parameter to the distance you want the targets to be able to move with each step in order for this effect to work.
