You cause spells cast by the target of this spell to come undone as they manifest. Afflicted mages that fail an initial will save against this spell must make a successful Will save each time they cast a spell or the spell fizzles upon the castings completion. Fizzled spells are completely cancelled, have no effect, and count as being cast by the target spellcaster.
Material Component: A loosely woven weave of cloth. Toss it in the direction of the target you wish to affect. It is consumed in the casting of the spell.
