The Dormayvoo appears as a humanoid zombie with no signs of decay. In poor light, it may be mistaken for a living being, but its face is slack and the eyes remain closed. It dreams a nightmare version of reality around it, allowing unfailing movement towards the living on which it will direct tireless blows from its fists. Being undead, it is immune to effects such as sleep, charm, or fear. With eyes always shut, it cannot be blinded, and it never sees holy symbols from which to be Turned by a Cleric. It can be destroyed by a high-level Cleric.
