Air Spout

Spiral air around to propel yourself upward. When you use this technique, you create a column of air and propel yourself upward by a maximum of 30ft, remaining stationary in the air. While Air Spout is active, you can move into spaces that are occupied by creature no larger than the height of the Air Spout. Creatures that you pass over with the spout and creatures that start or end their turn within the spout must make a Wisdom Saving Throw (if they’re an airbender) or Elemental Affinity Saving Throw (if they aren’t). On a fail, they take 3d10 bludgeoning damage and on a success half as much. You can move with the spout as a bonus action. If at any point the spout is or you are attacked, you must make a concentration check. On a fail, the spout dissipates and you start to fall. For every 10ft you fall you take 1d6 bludgeoning damage. At Trained level, the diameter of the spout becomes 10ft and you can propel yourself up to 100ft. At Mastered level, you can propel yourself upward to a maximum of 300ft.
