Prerequisite: Mastered Air Shield

A wall of strong wind rises from the ground at a point you choose within range. You can make the wall up to 50 feet long, 15 feet high, and 1 foot thick. You can shape the wall in any way you choose so long as it makes one continuous path along the ground. The wall lasts for the duration or until strong winds disperse it. When the wall appears, each creature within its area must make a Wisdom Saving Throw (if they’re an airbender) or an Elemental Affinity Saving Throw. A creature takes 3d8 bludgeoning damage on a failed save, or half as much damage on a successful one. The strong wind keeps fog, smoke, and other gases at bay. Small or smaller flying creatures or objects can’t pass through the wall. Loose, lightweight materials brought into the wall fly upward. Arrows, bolts, knives, projectiles made of fire and air or other ordinary projectiles launched at targets behind the wall are deflected upward and automatically miss (Boulders hurled by Earthbenders or siege engines, and similar projectiles, are unaffected.). At Trained level, you can make the wall an additional 10ft longer. At Mastered level, you can make the wall either an additional 10ft longer or 4 ft thicker. If you choose to make the wall thicker, projectiles made of earth that weigh less than 180lbs also can not pass through the wall.
