A gale of furnace-hot wind blasts downward in a 60 ft.-high, 20 ft.-radius cylinder.

When a creature moves into the spell's area for the first time on a turn or starts its turn there, that creature must succeed on a Dexterity saving throw or take 4d6 fire damage. A successful save halves the fire damage. Any creature that fails the save must also make a Strength saving throw. A creature that fails the saving throw becomes prone, and if it was in the air or flying it also takes the normal amount of falling damage it would take by falling from that height.

Creatures may attempt to stand up from prone on their turn by using an action to repeat the Strength saving throw. On a failure, they must succeed on a Constitution saving throw or gain one level of exhaustion. Any levels of exhaustion caused by this spell go away when the spell ends.

When cast at higher levels, the fire damage caused by the spell increases by 1d6.
