Undead: Immune to effects such as sleep, charm, or fear.

Eyeless Sight: 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.

Nightmare Vision: Dreams a nightmare version of reality around it, allowing unfailing movement towards the living.

Magical Sleep: Whenever the dormayvoo lands a blow of its fist, the victim must save vs. Petrify or fall into a magical sleep. Heroes of all levels may be affected by this magic, except those of elvish blood are immune. Those unlucky enough to fall under the effect fall down as if dead. In fact, the victims appear indistinguishable from the dead. 1d4 rounds later, they rise up as a dormayvoo themselves. Strong fighters wearing armor can be especially hard on their former companions. But these victims are not lost forever. The spell is a curse that may be removed by a Magic-user or Cleric, after which the unfortunate victim is restored to their former life.
