Arc

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

This spell’s damage increases by 1d6 when you reach 5th level (1d6), 11th level (3d6), and 17th level (4d6).
