You can convert any spell into an attack.
Prerequisites: Arcane spellcaster, caster level 10th.
Benefit: As a standard action, you can sacrifice a prepared spell or unused spell slot of 1st level or higher and transform it into a ray, targeting any foe within 30 feet as a ranged touch attack. This attack deals 2d6 points of damage plus an additional 1d6 points of damage for every level of the spell or spell slot you sacrificed. 0-level spells may not be sacrificed in this manner.
This is a supernatural ability.
