Arc Lightning

You create a bolt of lightning that arcs toward a target of your choice that you can see within range. The bolt then leaps from that target to an additional target within 15 feet. A target can be a creature or an object and can only be targeted once per use of this spell.

The target must make a Dexterity saving throw, taking 2d8 lightning damage on a failed save, or half as much damage on a successful one.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, you may cause the spell to leap to one additional target within 15 feet of the previous target for each slot level above 2nd.
