Those who seek the secret techniques of the air splitter often find rejection from the masters of the art and are told to find nature's master much as they did. These masters have perfected the art of using their blade to bend air in such a way that the air itself becomes a weapon enabling them to strike their foe without putting themselves in the line of fire.

The methods by which you came upon the art of air splitting are up to you, but most learn from the study of birds and how they keep themselves aloft while gliding.

Wind Strike

Beginning at 3rd level, you learn to project your attacks through the air to strike your foe. When you make a melee attack on your turn, your reach for it is 10 feet greater than normal.

Sweeping Edge

At 7th level, you have honed the technique of your wind strike to hit multiple enemies. As part of the attack action on your turn, you can expend two of your attacks to strike all creatures within a 15 foot cone making a separate attack roll for each which deal one additional damage dice.

You can use this feature a number of times equal to your Constitution modifier (minimum of once), and you regain all expended uses of it when you finish a long rest.

Momentum Strike

When you reach 10th level, your understanding of cutting through the air has gone further than just your blade. Your movement speed increases by 10 feet, additionally if you move at least 10 feet in a straight line toward a target right before making a melee weapon attack against it, you can roll one additional damage dice for that attack.

Revitalising Breath

Starting at 15th level, when you roll initiative and have no uses of Sweeping Edge remaining, you regain one use. 

Whirlwind of the Blade

Upon reaching level 18 you have become a master of bending the air around you, when you use your action surge you gain a flying speed of 60 feet for 1 minute, additionally while in this state you can make an extra attack as a bonus action.
