Blistering Disk

Raising your hand you awaken the sleeping essence of fire in the ashes you hold, bring to life a blistering flame and molding it, spinning the fire in a wide condensed wheel of flames. Directing it at a creature or object within range you can hurl the spinning disk of condensed fire. Make a ranged spell attack against the target. On a hit, the target and any others within a five feet radius of them takes 1d8 fire damage. Any targets hit with this attack must make a dexterity saving throw or be inflicted with a magical burn for 1 minute, dealing 1d4 fire damage at the end of each of it's turns. A flammable object hit by this spell ignites if it isn't being worn or carried.

This spell's damage increases by 1d8 when you reach 5th level (2d8)(2d4 magic burn), 10th level (3d8)(3d4 magic burn), and 15th level (4d8)(4d4 magic burn), and 20th level (5d8)(5d4 magic burn).
