Combustion

You send a burst of flames out from your hand. Make a melee spell attack against the target. On a hit, the target takes 1d8 fire damage. A flammable object hit by this spell ignites if it isn't being worn or carried.

The spell's damage increases by 1d8 when you reach 5th level (2d8), 11th level (3d8), and 17th level (4d8).
