A bright streak flashes from your pointing finger to a point you choose within range and then blossoms with a low roar into an explosion of flame. Each creature in a 20-foot-radius sphere centered on that point must make a Dexterity saving throw. A target takes 8d6 + your spellcasting ability modifier fire damage on a failed save, or half as much damage on a successful one.
At higher levels: Damage increases by 1d6 per spell slot level above 3rd.
