You create a 10-foot-radius sphere of shadow centered on you. The sphere spreads around corners, and its area is heavily obscured. It lasts for the duration or until a wind of moderate or greater speed (at least 10 miles per hour) disperses it. You are fully aware of the position of each creature in the shadow mist. You can use a bonus action to teleport in the shadowy mist on each of your subsequent turn.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the radius of the fog increases by 10 feet every 2 slot level above 5st.
