Daedric Crescent

You call upon a fiery blade into the free hand of a willing humanoid. The blade is similar in size and shape to a scimitar, and it lasts for the duration or until concentration is broken. If the person lets go of the blade, it disappears, but they can evoke the blade again as a bonus action. Those affected can use an action to make a melee spell attack with the fiery blade. On a hit, the target takes 1d8 fire damage. The flaming blade sheds bright light in a 10-foot radius and dim light for an additional 10 feet.  On the first successful attack on a creature with the magical blade, they must make a Strength save with your spell DC. If it fails, the creature is knocked prone.

At higher levels: When cast with a spell slot of 6th or higher, the fire damage increases by 1d8 for every other spell slot level above 4th. At 8th level, you can target an additional creature for a total of 2.
