Damage resistance

From NWNWiki

Creatures with damage resistance are able to ignore damage of a specific type up to a specified amount. Unlike damage reduction, damage resistance cannot be overcome with weapons with a higher enhancement bonus. Like damage reduction, the amount of damage resisted is listed as a value and a damage type, such as "fire 20/-". This means that the first 20 points of fire damage dealt to the character is ignored entirely.

In the special case of a weapon that deals more than one kind of physical damage, the lower of the resistances for those physical damage types is used. (Prior to version 1.69, the higher was used.)

[edit] Stacking

For the most part, damage resistance does not stack. For each damage type, only the highest resistance granted by a spell or (equipped) item is used. However, damage resistance from feats (resist energy and epic energy resistance) does stack with — and is applied before — other sources of damage resistance, even though the feats do not stack with each other.
