Sparking Shot

You imbue a piece of ammunition or weapon with crackling electricity. When you make an attack with the piece of ammunition or weapon, it creates arcs of lightning from the attack’s target. The target and two creatures of your choice within 15 feet must make a Dexterity saving throw, taking 3d12 lightning damage on a failure or half as much on a success. If the attack hits, the target automatically fails this saving throw.

The piece of ammunition or weapon then reverts to normal.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d12 for each slot level above 3rd.
