This is the first Phantom type enemy you face. At first it will teleport away from you, to the other side of the room. Do not try to follow it. Stay in one place and let the Ghost come to you. When you can strike it, use an Edged weapon to deal the most damage.
[view·edit·purge]A ghost is the soul or spirit of a deceased person or animal that can appear, in visible form or other manifestation, to the living. Ghosts are generally described as solitary essences that haunt particular locations, objects, or people they were associated with in life, though stories of phantom armies, ghost trains, phantom ships, and even ghost animals have also been recounted.
