Cinder Cloud

You create a 20' whirling cloud of smoke, ash, and burning cinders. The cloud spreads around corners and is heavily obscuring; visibility inside the cloud is 5'. Any creature in the area of effect takes 2d6 fire damage per round and must make a successful Constitution saving throw or become blinded for 1d3 rounds. The cloud remains for the duration or until you use an action to dispel it. A strong wind of at least 10 MPH will disperse the cloud.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage increases by 2d6 for each slot level above 2nd.
