This spell was recently developed by the church of Azuth in response to the creation of a mage-killing horror known as a magedoom by the powerful wizards of the Zhentarim. (See the Ruins of Zhentil Keep boxed set for details on this monster.) Azuth only grants this special spell to high-level specialty priests and wizards who serve him well. The spell is unaffected by a magedoom's 100% magic resistance.
This spell has no effect on any creature except a magedoom. When cast on a magedoom, the magedoom must succeed at a saving throw vs. spell or be destroyed. If the saving throw is successful, the magedoom takes 10d8 points of damage. The damage may destroy the magedoom anyway.
The material components for this spell are a holy symbol of Azuth, which is not consumed in the casting, and a magical item, which is consumed in the casting. Unique items, artifacts, and relics (as adjudicated by the DM) cannot be used as components of this spell.
Notes: Granted by the god Azuth of the Forgotten Realms setting.
