Fog Cloud | Action

You create a 20-foot-radius sphere of fog
centered on a point within 120 feet. The sphere
spreads around corners, and its area is heavily obscured. It lasts for 1 hour or until a gust of
wind disperses it.
When you cast this spell using a spell slot of 2nd
level or higher, the radius of the fog increases by
20 feet for each slot level above 1st.
