Zap!

This spell creates an electrical discharge that begins as a single stroke commencing from your fingertips. Unlike lightning bolt, Arc strikes one object or creature initially, then arcs to other targets. The bolt deals 1d8 points of electricity damage per caster level (maximum 10d8) to the primary target. After it strikes, lightning can arc to a number of secondary targets equal to your caster level (maximum 10). The secondary bolts each strike one target and deal half as much damage as the primary one did (rounded down). Each target can attempt a Reflex saving throw for half damage. You choose secondary targets as you like, they are hit one after the other but they must all be within 9m of the target that was hit before them, and no target can be struck more than once. You can choose to affect fewer secondary targets than the maximum.
