Ball Lightning

A 5-foot-radius sphere of floating concentrated electricity appears in an unoccupied space that you can see within range and lasts for the duration. Any creature that ends its turn within 10 feet of the sphere must make a Dexterity saving throw. The target takes 6d10 lightning damage on a failed save, or half as much damage on a successful one.

As a bonus action, you may move the ball up to 40 feet. The ball can pass through creatures of Medium size or smaller without stopping, while you can choose to ram the ball into larger creatures preventing the ball from moving any further. In either scenario, each creature must make the saving throw against the ball’s damage.

The sphere sheds bright light in a 40 foot radius and dim light for an additional 40 feet.
