Incendiary Cloud
A cloud of burning embers, smoke, and roiling flame appears within range. The cloud heavily obscures its area, spreading around corners and through cracks. When the cloud appears and a creature is in it, when a creature enters the cloud for the first time on a turn, or when a creature ends its turn within the cloud it makes a Dexterity saving throw , taking 10d8 fire damage on a failed save, or half as much on a successful one.
The cloud can be dispelled by a wind of at least 10 miles per hour. After it is cast, the cloud moves 10 feet away from you in a direction that you choose at the start of each of your turns.
