Skill Damage

Normally applies to skill damage of the user after any synergy bonus, and melee attack damage. Character screen displays +% Skill Damage being applied to ranged attack damage as well, but this is not actually the case. Applies to damage when applied and missiles when created: if there is a delay between skill usage and damage or missile creation, switching weapons or other equipment to apply more +% Skill Damage may result in more damage. Does not apply to pets summoned by the user (including sentry Traps), with the exception of Hydra. When using two weapons +% Skill Damage of both is applied to skill damage, or attack damage of either weapon when using a melee attack.
