Arm of Fire

You evoke an arm of pure fire from the plane of Avernus that sprouts from the shoulder.  The arm is similar in size and shape to your other, and it lasts for the duration. You can dispel it early.

You can use your action to make an unarmed attack with the arm. On a hit, the target takes 4d8 fire damage. The arm can set things on fire. The arm can be used to grab or hold things, however if it is flammable, it will combust. If you touch someone will the arm they take the burning damage.

The flaming arm sheds bright light in a 10-foot radius and dim light for an additional 10 feet.

You can use this ability once per long rest.
