Ball Lightning

You cause 5 balls of lightning to spring into existence. These spheres orbit around you for the duration at a distance of about 5 feet, shedding dim light at a radius of 10 feet around you.

As a bonus action on each of your subsequent turns, you can cause one of the spheres to dissipate into a lightning bolt, dealing 2d10 lightning damage to a creature of your choice that you can see within range. In addition, when you are targeted by a melee attack, you may cause one of the balls to strike the attacker (no reaction required), imposing disadvantage on the attack, and dealing 3d10 lightning damage if they miss. When all of the orbs have disappeared, the spell ends.
