concentration, 1 hour/mana

As an action, you create a sphere twice as big as normal of fog centered on a point within 20 meters. 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 15 kilometers per hour) disperses it. Creatures in the area are wet while within the fog and remain wet until the end of their turn that they leave the area.
