Peace of Wee Jas

This spell, a traditional part of funeral services for the clergy of Wee Jas and those who pay for it, grants the soul of the departed a certain amount of protection from disturbance. Any remains consecrated by this spell are immune to the effects of fourth-level and lesser spells that would animate or otherwise disturb the eternal rest of the departed, including Skeletal Servant and animate dead. Speak With Dead is likewise prevented unless cast by a servant of a deity of the dead (either Wee Jas or Nerull - The Reaper). It also guarantees the soul will not rise as a ghoul, ghast, wight, wraith, shadow, or other lesser undead (those with 6 HD or less), regardless of the method of death. It is no protection against the possibility of the deceased rising as a more powerful undead, particularly a ghost, vampire, or mummy.
The material component is a thin silver chain laid across the bare chest of the corpse (the chain is customarily bound around the body before it is dressed). If the chain is removed after the spell is cast, the spirit gains a saving throw vs. magic (as the soul's former class and level) to determine if the spell continues unbroken.
This spell has no effect if cast on a living being, or an already risen spirit or corpse.
