Cannonball

Using air propel yourself forward toward a location. When you use this technique, you charge forward to a location of your choosing that is within a distance equal to your remaining walking speed. If there is a creature in your path, they must make a Wisdom Saving Throw (if they’re an airbender) or a Dexterity Saving Throw (if they aren’t). On a fail, they take 4d10 bludgeoning damage and are pushed back 20ft. On a success, they take half as much damage and are pushed back 10ft. If the creature collides with an object, they further take 1d8 bludgeoning damage per 10ft traveled. You take the position of the creature you push back. At Trained level, you can travel +10ft in addition to your remaining walking speed. At Mastered level, the damage increases by 3d10 and you can travel +10ft in addition to your remaining walking speed.
