Destructive flame

A bright beam shines down onto a point within range. A wall of fire then blossoms outwards from the beam of light. Each creature in a 30-foot-radius, 10 foot tall Cylinder centered on that point makes a Dexterity saving throw, taking 5d6 Fire damage and 5d6 Force damage on a failed save or half as much damage on a successful one.

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

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