Unholy Shrouds

These shrouds look like ordinary funerary wrappings for dead bodies and are often decorated with symbols and icons representing the dead rising. If a dead body is wrapped in the shrouds, and the command word spoken, it returns as an undead creature.
The kind of undead it returns as is determined by the type of shrouds - lesser shrouds animate the corpse as a ghast, while greater shrouds turn the body into a wraith. The undead creature is not under anyone's control when it rises, though it may be commanded or controlled by the normal means.
Wrapping a body takes 10 minutes. The magic of the shrouds is usable once only, after which the wrappings turn to dust.
