In Diablo II, its chance to hit is reduced by defense (unlike other spells), and several monster types, especially in later difficulties, have Physical immunity or resistance. However, it is a full-fledged resistance in Diablo III. While other types of skills/attacks of elemental damage are commonly reduced or nullified by Elemental resistance or immunity, Physical resistance was introduced in Diablo II, but it is rarely shown, and it is not noted on the character sheet. Some skills, hero and monster alike, deal physical damage and may also do another type of elemental damage.
Necromancers, in turn, use the powers of Blood and Bone to deal Physical damage. In addition, Demon Hunters, who use the power of shadow itself, also deal Physical damage when they unleash hatred of the pure darkness. Bleed effects use Physical damage type as well. If damage type of a weapon or skill is not specified, it is most likely Physical. Any melee blow or kinetic missile will count as Physical. All the hero classes and almost all monster types have a physical damage attack as their default attack. Physical damage is the most common type of damage, associated with white, red or black colors.
