Flaming Sphere

You create a 5-foot-diameter sphere of fire in an unoccupied space on the ground within range. It lasts for the duration. Any creature that ends its turn within 5 feet of the sphere makes a Dexterity saving throw, taking 2d6 Fire 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, rolling it along the ground. If you move the sphere into a creature's space, that creature makes the save against the sphere, and the sphere stops moving for the turn.
When you move the sphere, you can direct it over barriers up to 5 feet tall and jump it across pits up to 10 feet wide. Flammable objects that aren't being worn or carried start burning if touched by the sphere.
