Breath of Wind

Inhale and exhale pressured wind in the direction you choose. When you use this technique, you breathe out a strong gust of air. Creatures affected by this technique must make a Wisdom Saving Throw (if they’re an airbender) or a Constitution Saving Throw (if they aren’t). On a fail, affected creatures are pushed back 10ft, knocked prone and take 3d8 bludgeoning damage. On a success, they take half as much damage. If the creature collides with an object, they further take 1d8 bludgeoning damage. At Trained level, range increases by 30 ft and damage increases by 2d8. At Mastered level, the damage increases by an additional 2d8.
