Combo Bolt

You send a shocking lightning bolt which bounces over to the next closest enemy, up to a maximum of 4 targets. For each target, make a ranged spell attack roll. You have a +2 attack bonus if none of the targets are resistant or immune to lightning damage. On a hit, the target takes 3d6 lightning damage. On a miss, the bolt fails and it does not bounce over to the next target.

At higher levels, the bolt deals 1d6+1 more lightning damage and gains 1 additional target for each slot above 2nd level.
