Ash Storm

Until the spell ends, choking ash and burning embers roar in a 20-foot-tall cylinder with a 40-foot radius centered on a point you choose within range. The area is heavily obscured, and exposed flames in the area are fanned.

Any fire in the area doubles in height, and any fire damage taken in the area increases by half the rolled die, rounding down. For example, a fireball cast at 3rd Level in the ash storms area will do 12d6 fire damage.

The air in the area is filled with thick ash and burning embers, making it difficult to see. When a creature enters the spell's area for the first time on a turn or starts its turn there, it must make a Constitution saving throw. On a failed save, it is blinded.
