Violate Spell
( Book of Vile Darkness, p. 50)[Metamagic]
The character can transform one of his spells into an evil spell, and the wounds the spell inflicts are tainted with the foulest evil.
Prerequisite
Any evil alignment,
Required for
Touch of Hate (PG) ,
Benefit
This feat adds the evil descriptor to a spell. Furthermore, if the spell deals damage, half of the damage dealt is vile damage. For example, a violated lightning bolt cast by an 8th-level wizard deals 8d6 points of damage: 4d6 points of electricity damage and 4d6 points of vile electricity damage (but creatures immune to electricity take no damage). A violated spell uses up a spell slot one level higher than the spell's actual level.
Special
A character may take this feat multiple times, choosing a different spell each time.
