Confringo (HP)

A tiny ball of fire flashes from your wand to a point you choose within range and then explodes into a fiery blast on impact. Each creature in a 10-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 fire damage on a failed save, or half as much damage on a successful one. The fire spreads around corners. It ignites flammable objects in the area that aren’t worn or carried.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d6 and the radius increases by 5 feet for each slot level above 5th.
