Burning Arc

This spell causes an arc of flame to leap from your fingers, burning a number of enemies nearby. It deals 1d6 points of fire damage per caster level (maximum 10d6). For every additional target the discharge arcs to, reduce the number of damage dice by half (rounded down). Therefore, at 9th level, your burning arc deals 9d6 points of fire damage to the primary target, then 4d6 points of fire damage to a secondary target, then 2d6 points of fire damage to an additional target. Each target can attempt a Reflex saving throw for half damage.
