Air's Champion: Derecho

You summon the strength of the Air Elemental. Invoking your right as Champion of the Air you create a straight line, 240x20 feet, of wind that deals direct force damage to all creatures, including allies, who are met with the wind and the debris. The spell moves you back 15 feet and can push targets up 60 feet, for every point in your DEX modifier you remove 10 feet of affect (at +5 the target is not moved at all). All creatures must make a DEX (DC:15) and on success take half damage. This can be used while airborne, minimally affects the line of action, under the discretion of the DM.
