Ranged Damage

Ranged Damage is the form of damage dealt by long ranged weapons. Ranged Damage increases as  Agility increases, and is the preferred form of damage for the Hunter and Bard.

Ranged Damage is a subset of  Physical Damage, therefore Ranged Damage caused by basic attacks benefits from  Life Steal and  Mana Steal. Ranged Damage is countered by  Armor, which in turn is countered by  Armor Penetration.
