Ball Lightning

You summon a ball of stormy energy and hurl it at one target you can see within range. Target must make a Dexterity Saving Throw against your Spell Save DC. On a failure, the target takes 3d10 lightning damage and half damage on a success. Also on a failure, you magically teleport to an unoccupied space within 5ft. of the target. Damage increases by 1d10 per spell level above 3rd.
