Most monks dedicate themselves to the art of their weapon but you have taken it one step further and treat your weapons as a simple extension of your own body.

After becoming at peace with both your soul and your weapons, you have gained new abilities. Through spending a time meditating and studying not only your weapons of choice but also your inner most self you have been able to let your ki extend out into weapons of your choice.

Ki Weapon

3rd-level Way of the Ki Weapon feature

Activation

Using a Ki point and a bonus action you can touch a weapon and cause it to fly for 10 minutes. You can move the weapon up to 50ft away from you, using your own movement on your turn. When taking the attack action you can attack using the weapon with it's own range from it's location. When attacking with a Ki Weapon instead of using STR or DEX modifiers use your WIS modifier. The weapon will have an AC equal to your wisdom score. When hit the weapon will be knocked directly away from the attack 10ft.

Attack/Defence

Using a Ki point and a bonus action you can cause all flying weapons to change mode. When in defence mode all weapons will disappear from their current position and surround you, for each weapon increasing your AC by 1. Using an additional Ki point can switch the mode to attack and the weapon(s) may move freely beginning from your location.

Sacrificial Play

6th-level Way of the Ki Weapon feature

Using a Ki point and an attack you can swap places with your weapon as long as the chosen weapon is within 60ft and line of sight. This swap does not provoke opportunities of attack. The space being swapped to must be large enough to fit your body in its' current shape, when swapping you keep your current velocity.

A Monk's Best Friend

11th-level Way of the Ki Weapon feature

An Extension of the Self

Your use of channelling Ki through weapons has grown in power through practice.

At the end of a long rest you may choose up to 3 weapons that are able to become Ki weapons without using a Ki-point as long as they are within 100ft and line of sight. There is no time limit on these weapons however you are able to take the Ki weapon properties off the weapon to be wielded as normal with the same limitations as activation.

Flurry of Blades

When taking the flurry of blows bonus action you are able to use your Ki Weapons in place of unarmed attacks. 

The Ki Maelstrom

17th-level Way of the Ki Weapon feature

In one burst of Ki you are able to rapidly attack a large area with every Ki weapon available.

Using an action and 5 Ki-points, every creature of choice in a 15ft radius around you receives an attack from every Ki weapon currently created.
Any creature of choice that enters or begins its' turn in the area of effect will receive the attacks as well.
You may move around inside the area but if you leave the effect will end immediately.
The Maelstrom lasts 30 seconds.
