Downpour

You create a 20-foot-radius and 30-foot-height cylinder of heavy rain centered on a point within range. The cylinder spreads around corners, and its area is moderately obscured. Creatures within the area have disadvantage on attack rolls, and saving throws focused on sight (Perception).

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