Desiccate

Dessicate
Prerequisites: none
When this character dies, rather than decomposing normally, the character simply loses his body water becoming a withered up mummy that only suffers such damage as caused his demise. This withered up corpse survives for hundreds of years more or less intact, allowing Raise Dead to be cast without difficulty. Also those casting Animate Dead can create a Zombie rather than having to settle for a Skeleton.
The spell was rumored to have been created by the wizard Ashen Aurgobath who opened Zombie Tavern in 1660.
