Reanimated Dead

Corpses that have been brought back to a semblance of life through dark magic, reanimated dead are mindless creatures which seek extermination of the living. While slower than they were in life, these creatures possess unnatural resilience, their toughened flesh more easily endures the ordinarily bone shattering hits of maces, as well as the stab of arrows and similar weapons. Blades will cut what remains however, and bring them down. While they have lost any unique fighting styles or knowledge they possessed while living, they retain the ability to wield any weapon they were once familiar with, and may be armed.

Reanimated Skeletons
Similar to the reanimated dead, these are skeletons of creatures that haven been reanimated through dark magic. They are more nimble than their counterparts, and due to their relative lack of flesh are harder to damage by slashing or piercing attacks. They are also immune to the cold, which does little against their toughed bones. Maces will shatter them, however, reducing them to bony heaps.
