Fog Cloud

You create a 20ft radius sphere of fog centered on a point within range. 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 10mph) disperses it.

At Higher Levels

When you cast this spell using a spell slot of 2nd level or higher, the radius of the fog increases by 20ft for each slot level above 1st.
