A wave of rainclouds rolls out from a point you can see within range, covering a cylinder up to 500 ft long and 50 feet high. For the duration, light rain falls in this area, extinguishing unprotected flames, and you can cause harmless claps of thunder or flashes of lightning to emanate from the clouds. The spell ends if you dismiss it (no action required), or if a wind of moderate or greater speed (at least 10 miles per hour) disperses the clouds.
