You create three arcs of lightning striking targets in range. You can direct them at one target or several. Make a ranged spell attack for each arc. On a hit, a target takes 1d12 lightning damage. If three or more arcs hit a single target, it must make a Constitution saving throw or become shocked, stunning it until the start of its next turn.

At Higher Levels : When you cast this spell using a spell slot of 3rd level or higher, you create one additional arc for each slot level above 2nd.
