Dreary Sky

You create a 10-foot-radius cloud of dark fog centered on a point within range. The sphere spreads around corners, and its area is heavily obscured.

When any enemy stands beneath the fog they will suddenly feel incredibly sad. All effected enemies will have disadvantage on any CHA, DEX, or STR checks/saving throws till the fog is removed or if they move out from underneath the cloud  

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the radius of the fog increases by 10 feet for each slot level above 1st.
