Fog Cloud

From Player's Handbook, page 243.

Description
1st-level conjuration


 * Casting Time: 1 action
 * Range: 120 feet
 * Components: V, S
 * Duration: Concentration, up to 1 hour

You create a 20-foot-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 10 miles per hour) 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 20 feet for each slot level above 1st.
