Ashfall

A dense cloud of ash clots the air and smothers any horizontal surface within a 20-foot-radius, 20-foot-high cylinder centred on a point within range. The area becomes heavily obscured for the duration of the spell. The ash spoils any exposed drink in the area, making it unconsumable, and non-magical flames have a 50% chance of being extinguished on initiative count 1. In addition, any creature that starts its turn within the area must succeed on a Wisdom saving throw or become blinded until it uses an action to remove the ash from its eyes. A creature that is wearing sufficient eye protection automatically succeeds on this saving throw.

You may end the spell early using a bonus action.
