Arcane Bolt [Incantation]

Your bond with magic itself allows you to channel bolts of arcane energy.

Prerequisite: Knowledge (arcana) 4 ranks, ability to cast 1st-level arcane spells.

Benefit: You can channel bolts of arcane energy. You must make a DC 5 channeling check. If the channeling check succeeds, you may attack one opponent within 30 feet with a ranged touch attack that deals 1d6 points of damage.

Special: For every 3 points by which you increase the DC, the arcane bolt deals an additional 1d6 points of damage.
