This spell may only affect the caster. Its effects last for 1 hour per level of the caster. If slain during this time, the Necromancer's spirit is released and may try to inhabit the body of any other living creature during the next 2D4 combat rounds. The caster's invisible spirit has a M of 6 and must begin from the character's dead body. The spirit must touch a host creature in order to inhabit it. The host is allowed to make a test against WP and, if successful, the spirit may not inhabit that body. If the test is failed, the Necromancer inhabits the body of the victim until either it is slain or the Necromancer's spirit is driven out by magical means. The victim's psyche is not destroyed, but is suppressed by the possessing Necromancer. The spellcaster does not gain access to the thoughts, memories, and knowledge of the victim, and if the Necromancer is ever driven out of the body, the victim regains full control.
The Necromancer's wandering spirit cannot be harmed by any physical or magical attacks, though it cannot enter any magical Zone that keeps out Ethereal Undead. If the Necromancer's spirit fails to find a new body within 2D4 rounds, it is blown to the winds and destroyed.
As a spirit, the Necromancer has no magical or physical powers at all. Having acquired a new body, the Necromancer's Ld, Int, Cl, and WP characteristics are regained, as are all skills and magical powers (including magic points). But all other characteristics are now those of the host creature.
