Air Shield

When you use this technique as an action, you bend the air within 20ft of you and create a dome of air up to 20ft in diameter centered on you. The dome doesn't run out of breathable air. Ranged attacks that would pass through the dome are made at a disadvantage however on a hit, they suffer -2 to their total damage roll. Any creature can enter or leave the dome at any point. When you use this technique as a reaction, you send out a 20ft dome of air outward originating at your position. Any ranged attack made against you or anyone within 20ft of you at the moment of you using this automatically doesn't hit. Every level above Practiced, the diameter of the dome increases by 5ft.

*Can be used as an action or a reaction
