There are currently 5 main types of damage, they are Physical, Fire, Cold, Lightning, and Chaos. Fire, Cold, and Lightning are collectively known as Elemental Damage. Damage reduction only affects physical damage. The other four damage types each have their own resistance value (e.g. "Fire resistance") which is viewable in the character sheet. Resistances reduce damage taken, and are normally capped at 75%. However, there are passives and items that can increase your maximum resistances to allow for values higher than 75%.
If a passive does not specify whether it affects weapon or spell damage, it will affect both.
This page focuses on damage being dealt by the player. For information on how the elements affect you, see Status Ailments and Resistances. For information on skills that deal non-physical damage, see the Chaos, Cold, Fire, and Lightning keywords.
Main Damage Types
- Main article: Physical damage
Physical Damage is usually dealt by weapons (melee or ranged) but can also come from some spells, like Glacial Cascade, Bear Trap, Ethereal Knives and Shockwave Totem. Most sources of life leech and mana leech only apply to physical attack damage when determining how much life or mana is gained. Many passive attack skills only increase physical damage, especially those which apply to a specific weapon type.
