Blazing Dive

Superheated air collects under you, buoying you high into the sky before you plummet back down in a fiery comet. You Fly 15 feet straight up into the air, then Fly in a straight line to an empty space of your choice on the ground within 60 feet. You land with a fiery explosion, shaking the ground beneath, dealing 6d4 Bludgeoning damage and 6d6 Fire damage to all creatures in a 15-foot emanation and knocking them Prone.
Affected creatures can attempt a Strength saving throw to avoid being Prone and a Dexterity saving throw to avoid the damage, taking only half as much on a successful one.

Using a Higher-Level Spell Slot. The damage increases by 1d4 bludgeoning and 1d6 fire for each spell slot level above 5.
