Aerial Strike

You conjure a vortex of roaring flame that climbs towards the sky at a point within range. Each creature in a 5-foot-radius, 120-foot-high Cylinder centered on a point within range makes a Dexterity saving throw, taking 2d12 Fire damage and 2d12 Bludgeoning damage on a failed save or half as much damage on a successful one. If a flying creature fails this save, it loses its flying speed and falls until it either hits the ground or uses all of its movement and an action to stop falling.

Using a Higher-Level Spell Slot. The Fire damage or Bludgeoning damage increase by 1d12 for each spell slot level above 3.
