This spell supplements the magic jar spell and
is used to allow a wizard to transfer his consciousness into specially
prepared corpses and even non-intelligent undead.
The corpses can be mindless undead and must be
prepared through a special ritual (10 minutes or so) before they
can be used. Once the spell is completed it takes the caster 1 round
to transfer his consciousness from one corpse to another or to recover
his consciousness from having a corpse destroyed.
He is able to cast verbal and somatic spells
through the corpse as if it were his own body. If a cleric attempts
to turn an inhabited corpse, it turns as a creature of the casters
hit dice. If he is turned he is forced from that body (permanently)
and stunned for 1 round, he may then inhabit another form, which
takes a 2nd round.
If the wizard is sealed against returning to
a corpse or has none left he returns to the jar or his body. Inhabited
corpses have as many hit points as the wizard.
