Voltaic Arch

Lightning forms in one of your arms before you launch it against one creature you can see in range. Make a ranged spell attack against that creature. On a hit, the target takes 1d6 lightning damage.

If any other creature is within 5 feet of the target and you can see it, you can choose to bounce the lightning once into that creature as part of casting this spell, forming an electric arch. Make a new ranged spell attack against the new creature. On a hit, the second target takes 1d6 lightning damage.

This spell's damages increases by 1d6 for the first and second target when you reach 5th level (2d6, 2d6) and 17th level(3d6, 3d6). Additionally, at 11th level, the number of targets you can bounce the arch increases to 2, making 3 the number of targets. The new target must be within 5 feet of one of the first two targets.
