Publication:Dread Codex 2/New Spells/Falnor's Guise of Death

As this spell is cast, a shadow of death masks the caster. He is now detected as being an undead, though he is not. There is nothing different about the caster. He looks and smells just like he normally would, but any who tries to detect undead, will reveal the caster as being an undead. This would fool a cleric, who may try to turn him, but this could never work.

Note that the caster has none of the undead traits. There is also a 50% chance that another undead of lower HD than the caster would recognize the caster as being an undead and not attack him, unless the caster threatens them, thereby provoking an attack.
