Ball Lightning

A 5-foot-diameter sphere of lightning and electricity manifests and releases from your hands. It appears in an unoccupied space of your choice within range and lasts for the duration. Any creature that starts its turn or comes within 5 feet of the sphere must make a Dexterity saving throw. The creature takes 2d6 lightning damage on a failed save, or half as much damage on a successful one.

As a bonus action, you can move the sphere up to 30 feet in any direction.

It sheds bright light in a 20-foot radius and dim light for an additional 20 feet.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 1d6 for each slot level above 2nd.
