Bludgeoning is a physical damage type caused by smashing an opponent with a heavy, flat or rounded surface. This type of damage can be mitigated with bludgeoning damage immunity, bludgeoning damage resistance, or general damage reduction. It is often a favored damage type of undead hunters, as skeletal undead (e.g. skeletons) tend to have 50% immunity to other physical damage types, but not to bludgeoning damage. The following spells cause bludgeoning damage: bombardment, ice storm, earthquake, Evard's black tentacles, and drown.
