Damage shield

Damage shield refers to damage that is inflicted on an enemy after striking a player in melee. Damage shields are a special type of reactive effects.

Damage shields trigger off every melee attack and are not limited by a cooldown; hence, they are more potent against fast-attacking enemies. The damage inflicted is not considered spell damage and thus is not capable of triggering spell hit procs. Furthermore, damage shields do not share the combat log mechanic with spells; instead, they use a dedicated mechanic.
