This article is about the non-boss ranger. For the boss ranger of the same name, see Bone Dragon (Boss). For the necromancer of the same name, see Bone Dragon (Necromancer).
Bone Dragons are undead creatures and as such take double damage from holy skills and weapons. Also, even though undead, they are also fleshy creatures and thus can suffer from Bleeding or be Poisoned. Standing adjacent to ordinary Bone Dragons will cause players to become Diseased; Bone Dragon bosses do not seem to possess this property.
