Elemental damage

Elemental damage usually is caused by spells or as bonus damage from weapons on top of their physical damage. The game implements damage types connected to the four major elemental planes plus one of the four para-elemental ones:
*acid – connected to the Elemental Plane of Earth;
*cold – connected to the Elemental Plane of Water;
*electricity – connected to the Elemental Plane of Air;
*fire – connected to the Elemental Plane of Fire;
*poison - connected to the Para-elemental Plane of Ooze.
A creature may be resistant or even vulnerable to one or more of these. It should be noted that Magical damage behaves the same, but is not listed here since it is not elemental. It should also be noted that Poison damage is really not treated as an elemental damage by the game engine in any consistent way. For instance, the 7th Level arcane spell Protection From The Elements excludes poison damage, and the 8th level arcane spell Protection From Energy also does not add poison damage as an "energy type". For most intents and purposes, Poison Damage is a stand-alone damage type in the game. Disease effects that deal damage, use Poison Damage as the type.
In the original game, elemental hits could interrupt spellcasting even with 100% or more resistance (immunity). This has been changed in the Enhanced Editions.http://blog.beamdog.com/2018/08/updates-to-infinity-engine.html
