Anathema Spell (Feat)

Prerequisites: Spellcraft 24 ranks, Knowledge (Arcana) 24 ranks

Benefit: Instead of inflicting physical or energy damage, an anathema spell damages the spell power of a target. It inflicts a number of points of spell power damage equal to the amount of damage the spell would have normally inflicted. This damage is taken from the lowest spell levels first and works its way up. The spells lost are random and creatures without spell power (i.e., non-spellcasters) are unaffected. If the spell normally allows a saving throw, success on the throw always reduces the damage by half.

An anathema spell uses up a spell slot six levels higher than the spell's actual level.
