Ash Cloud

You spew embers from your mouth, creating a 5-foot-radius sphere of choking ash centered on yourself. The sphere spreads around corners, and its area is Heavily Obscured. The ash causes spells cast with a verbal component to be at a Disadvantage, as it makes it hard to breathe, and attempting to speak becomes difficult without coughing. It lasts for the duration or until a wind of moderate or greater speed (at least 5 miles per hours) disperses it.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the radius of the ash increases by an additional 5 feet. Add an additional 5 feet for every 2 spell levels added after 3rd.
