Way of Water

Monks that fallow this way have studied the flow of water and learned how to move their bodies in such way as to avoid incoming attacks like a flowing river and strike with vicious force like a tidal wave. 

Flowing River

At 3rd level when you take the Dodge action you may spend up to 3 ki points and add the number of ki points spent multiplied by 2 to your AC until the beginning of your next turn. Additionally if an opponent misses a melee attack on you while you are taking the Dodge action you may spend your reaction to redirect the attack using their roll against their own AC. If this hits you may deal damage to the enemy equal to 1d4 (scaling with your Martial Arts die).

Rushing Wave

At 6th level when you take the Dash or Disengage action you gain an additional 10 ft of movement. Additionally when you take the Dash action and are running in a straight line towards an enemy from at least 10 feet away you may spend 1 ki point and make a melee weapon attack on the enemy and stop moving. Your remaining movement is transferred to your damage bonus equal to the amount of movement speed remaining divided by 5.

Calming Pond

At 11th level you may meditate for 10 minutes in order to gain +1 to your AC and advantage on Wisdom and Dexterity saving throws for 8 hours. You can not regain these benefits until after completing a long rest.

Crushing Ocean

At 17th level you gain the ability to deal Crushing Blows. When you land an unarmed strike you may choose to spend up to 5 ki points and deal additional damage to the target equal to 5 times the amount of ki points spent.
