Ball Lightning

You point at one creature you can see within range, and a ball of electrical energy is released towards said creature. The target must succeed on a Dexterity saving throw or take 1d8 lightning damage. If the target is missing any of its hit points, it instead takes 1d12 lightning damage.

The spell’s damage increases by one die when you reach 5th level (2d8 or 2d12), 11th level (3d8 or 3d12), and 17th level (4d8 or 4d12).
