This spell effectively slays a creature from the Prime Material Plane who was brought to another plane by astral spell. The priest accomplishes this effect by magically severing the silver cord that ties him back to his home plane.
A chopping motion directed at the subject of the spell extends a scythelike blade of invisible force. If the target fails his saving throw versus death magic, the spell slices the cord and the prime dies. If the caster is able to detect invisibility or otherwise see astral objects so that he can perceive the cord, the victim's saving throw is modified by a - 2 penalty.
Notes: Rare for planar priests. Unlikely to be learned except through visiting the Outer Planes.
