"Wraiths are even feared by us demons. They are a strange form of undead and are almost impossible to kill except by way of soul magic. Wraiths are able to make any part of their body corporeal at any given time. This means even the fingertips can be corporeal while the rest of the body is untouchable. They are a more evolved form of ghosts that can not physically harm you, but they can drain your energy. If you get into a group with both and do not know how to kill them, then you are basically asking to die." Diablo explained.
