Gust of Wind

A violent wind blows from you to the far end of the line. It extinguishes small non-magical fires, disperses fog and mist, blows around objects of light Bulk or less, and pushes larger objects. Large or smaller creatures in the area, and those that later move into it, must attempt a Fortitude save. On a success the creature can't move against the wind; on a failure it is knocked prone (or suffers the critical failure effect if flying); on a critical failure it is pushed 30 feet in the wind's direction, knocked prone, and takes 2d6 bludgeoning damage.
