Ball lightning

You manifest an orb of crackling electricity in your palm and throw it at any single creature you can see within range. Make a ranged spell attack against the target. On a hit, the creature takes 1d6 lightning damage and has disadvantage on its next attack roll.

This spell's damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
