Way of the Wind

Starting when you choose this tradition at 3rd level, you can move the air around you. As a bonus action you may move any object or creature within 20 feet of you 5 feet to an unoccupied space for as long as the object or creature you move is large or smaller. This movement does provoke attacks of opportunity.
Additionally you may cast gust of wind as an action by spending 1 ki point. You don't need any components if you cast gust of wind in this way.

Stride of the Wind

At 6th level, your movements are like the wind. The step of the wind ki feature no longer costs any ki points.

Airbending Mastery

Beginning at 11th level, you have mastered bending the air around you. As an action you can spend a ki point to push a creature or an object of a large size or smaller within 30 feet of you 60 feet in a straight line if it fails a strength saving throw. If it succeeds the strength saving throw the creature is only pushed back 30 feet. If this movement is stopped or blocked by another creature or object, both objects or creatures are dealt 1d6 bludgeoning damage per 5 feet of remaining movement.

Additionally you may cast Wind Wall by spending a ki point without needing any of the components.

Eye of the Storm

At 17th level, you control the winds around you, hindering the movement of your foes. All creatures except those you designate as allies that start their turn within 30 feet of you have their movement halved.
