Immunities

Intro

The listing here is mainly for enemy AI scripters who wish to see which immunities they may have to take into account. The two big tables at the end are a selection based on an extract of the game's files (kindly generated by FSR using the Near Infinity code base). Since they were mostly automatically generated, they should be pretty complete. I've narrowed the extraction down to immunities relevant to enemy AI scripting, meaning immunities that can be used by the party or their summons. Should you be interested in the original (unformatted) extraction (for party AI scripting or just for the sake of overcompleteness), you may find it here (right-click to download).

Using this listing, it should be reasonably easy to find out which items or spells can counter your critters' powers. Immunities can be bestowed by spells, activated abilities of items, permanent abilities of equipped items or be possessed by certain creatures naturally. The file type lists the source of the immunity; creature, item or spell.

Note that many spells are not normally detectable by scripts. Scripters are advised to install one of the many versions of Detectable Spells.

An example of how to use this listing:
Suppose you wish to script a mage using Maze in a manner befitting of his 18 Intelligence. Looking at the Immunity to effect table we can tell that the various rage abilities provide immunity to the Maze effect, and also that the Aerial Servant summon is innately immune to it.

Looking down the Immunity to spell table we can tell that Mordenkainen's Swords are immune to the Maze spell specifically, and also that activating the Greenstone Amulet, drinking a Potion of Clarity, wielding the Psion's Blade +5 or Chaotic Commands will make one immune.

Since an intelligent mage should be aware of at least some of these immunities, you can use various combinations of Race(), CheckStat(), StateCheck() and HasItemEquiped() checks to filter out immune creatures when looking for a suitable target to cast Maze on.

A note about "immortal" creatures:
Creatures with one of the MINHP flag items cannot be killed through normal means. However, almost all of those creatures are vulnerable to Mind Flayer "brain drain". Use Shapechange (or Limited Wish) if you plan to kill immortals. Warning: this may ruin some quests or plots; be sure you know what you are doing.
