Combustion

You snap your fingers to unleash a short ranged blast of flame that burns your enemies.  Make a Melee spell attack against the target.  On a hit the target takes 1d10 fire damage. A flammable object hit by this spell ignites if it isn't being worn or carried.

This spell's damage increases by 1d10 when you reach 5th level (2d10), 11th level (3d10), and 17th level (4d10).
