ARCANE BLAST [Sorcerer]

You can convert any spell into an attack.

Prerequisite: 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.

Special: This is a supernatural ability.
