Through the use of this spell, the savant is able to drain and utilize the memory of a spell possessed by a spell-using creature. The savant, if aware of the spells known by the subject, can declare which spell is drained; otherwise, the most recently memorized of the subject's highest-level spells is drained. The savant cannot regain the 7th level spell slot until the stolen spell is cast or the memory is lost.
Material components are also necessary if the spell normally requires them.
Notes: Restricted to savant-clerics. (Updated from Dragon Magazine.)
