Gale

A burst of wind from your own position that pushes everything outward, and hurts nothing. Mobs, players, items, arrows and boats are all caught. It never moves you and does no damage itself, though what happens when a pushed mob lands is another matter.

The radius and the push strength both equal the level, so at level X it is a ten-block sphere and the push is more of a launch than a shove. Aiming does not move it; where you stand does. Costs mana, no soul.
