Arc

A bolt of lightning bursts from you to a creature within range. On a hit, you deal 1d6 damage if the total damage of the rolled dice is an odd number the bolt then automatically arcs from one creature to another within 10 feet. Make a new damage roll against the new target, which could cause the bolt to leap again. on a critical hit the bolt jumps to another target regardless of the rolled damage total. A creature can be targeted only once by each casting of this spell.

Damage increased by 1d6 when you reach 5th level (2d6), 11th level (3d6) and 17th level (4d6).
