Double Firebolt

You get to launch firebolt but there's two. On a hit, the target takes 2d10 fire damage. A flammable object hit by this spell ignites if it isn't being worn or carried.

This spell's damage increases by 2d10 when you reach 5th level (4d10), additional 4d10 11th level (8d10), and additional 4d10 17th level (12d10).
