Wukong

Through work and meditation, your mindfulness has created a full and constant awareness of yourself. Your ki flows through you and your weapon as if holding together its shape, and you become capable of more agile and free movements.

Level 3: Freedom of the Fighting Buddha

Your mastery of inner freedom allows you to jump/flip over enemies and strike them as well as the ability to strike with your weapon where you would normally only be able to strike with your fist.

Once per turn, when you would make and unarmed strike, you may instead make an attack with your monk weapon.

When you would take the disengage action, you may instead jump up to twice your jump distance and make a melee weapon attack (this cannot be reacted to and counts as an attack).

Level 6: Projection of the Material Form

 

By sending out some of your ki, you are able to make duplicate of yourself which will copy and action you perform.

As a Bonus Action, you may spend any number of ki points to make that many duplicates of yourself within 20 ft of your location. These duplicates have exactly your stats and equipment except for the following: These duplicates have no move speed and have hp equal to a number of martial arts die times your proficiency bonus (3d6 at level 6). The duplicates have no turn in initiative, but have individual reactions which reset on your turn. Whenever you make an attack, bonus action, or reaction, you may have any number of your duplicates do the same (you may also have any number of duplicates and yourself copy a duplicates reaction). The duplicates last for 6 seconds times your proficiency bonus (18 seconds at level 6) or until reduced to zero hp at which point they vanish without a trace.

Level 11: Empowered Weapon

Your mastery of your weapon allows you to use it in place of your own hands, and you can channel the ki flowing through it to change its size at a word. 

Any time you would make an unarmed attack, you may instead make an attack with your monk weapon.

You gain the ability to cast enlarge/reduce on your monk weapon at will without requiring material components.

Level 17: King of Nothing

You can impose your dedication to inner freedom on creatures around you, leading them to drop material belongings or suffer damage from their greedy attatchments.

As an action, all creatures of your choice within 50ft of you must succeed on a DC20 wisdom saving throw or drop all items they are holding. Creatures may choose to fail the throw. Creatures that succeed the throw take 4d8 psychic damage. You gain ki points equal to half the number of creatures that failed their save (can go over max ki points, but will go down to max after a long rest). This ability can be used once per long rest.
