Divine Arrow Fuga

The user must first conjure strong flames in either hand and then compress these flames together, whilst continuing to conjure more into the inferno. Once enough pressure is reached, the flames are shaped into a blazing arrow that is then fired at ludicrous speeds. Each creature in a 5-foot-radius Sphere centered on that point makes a Dexterity saving throw, taking 7d12 Fire damage on a failed save or half the damage on a successful one.

Flammable objects in the area that aren’t being worn or carried start burning.

Using a Higher-Level Spell Slot. The damage increases by 1d6 for each spell slot level above 3.
