Stealspell

By means of this incantation, any single spell-caster chosen by the caster must save vs. spell at -1 or suffer the theft of any one memorized spell or spell-like ability use from his or her mind. The stolen spell is determined randomly; the identity of the stolen spell is not revealed by its theft. If no spell is available, the stealspell is wasted.

The stolen spell is transferred at the end of the round in which the stealspell is cast. A spell in the process of being cast cannot be stolen. The magic of the stealspell works in spite of all known shielding spells, save antimagic shell.

A stolen spell can be cast immediately by the user of this spell, or held in mind up to 24 hours. The casting can be made without understanding or sufficient level to cast the stolen spell. Any spell cast in this fashion is cast as if by the being from whom the spell was stolen.

While the spell itself has no material components, any material components required by the stolen spell and carried by the original owner are expended at the time the spell is stolen.

This powerful magical spell is rarely known beyond the circles of the Witches of Rasheman, and how it came into the hands of Shoon is unknown.
