Cloak of Undeath

The creature touched gains an aura which causes undead to see it as one of their own and ignore it, as long as it takes no actions to harm them. Skeletons and zombies and other such mindless undead are automatically affected. Other types of undead are allowed to make an Intelligence saving throw the first time they notice a creature protected by this spell. If successful, they see through the shroud and may act normally. When a creature protected by this spell harms an undead creature, the creature harmed is no longer fooled, and all other undead creatures who witness the act are allowed to immediately roll a new saving throw to end the effect for them.
