way of the harmonious spirit

Way of Harmonious Spirit
Monks of the Way of Harmonious Spirit’s goal is to create an art that practitioners could use to defend themselves while also protecting their attacker from injury. Striking against an armored opponent proved ineffective, so practitioners learned that the most efficient methods for neutralizing an enemy took the form of pins, joint locks, and throws. These techniques were developed around the principle of using an attacker's energy against him, rather than directly opposing it.

Technique Over Power

Starting when you choose this tradition at 3rd level, your teachings have taught you that proper applied techniques can help you in a Grapple, throw, or knocking your opponent to the ground more than brute strength alone. You may now add your wisdom modifier to all grapple and Shove Checks and at the start of each of your turns, you can deal your martial arts die in bludgeoning damage to one creature grappled by you.

In addition, when you have an enemy grappled you may spend Ki for any of the following effects as a bonus action:

-1 Ki point: Make a shove check. If you succeed the creature is knocked prone or thrown up to 15 feet away from you. The creature takes your martial arts damage die as fall damage minimum of one die. 

-1 Ki point: The creature must succeed on a Strength saving throw or be disarmed of an object you choose. The object lands at its feet.

-1 Ki point: make another grapple check. If you succeed, the creature is restrained until the grapple ends.

Deflect Blows

At 6th level, you can manipulate your enemy’s weight and power and redirect the momentum to get them into a Grapple. You may now use your Deflect Missiles ability against melee attacks. If you would reduce a melee attack's damage to 0, instead of catching and making an attack with the weapon, you may initiate a grapple against the attacker for 1 Ki as part of the same reaction.

Harmony of Body and Soul

At 11th level, you are able to use your ki to reinforce your body or your soul. As an action, you may spend 4 ki to do one of the following effects, Body or Soul. You can end this effect as a bonus action or it automatically ends after 1 minute. You cannot use Harmony of Body and Soul again until you finish a short or long rest.

Body: You use your own ki and send it through your bones and muscles growing in size and strength. For 1 minute your size doubles in all dimensions and your weight is multiplied by eight. This growth increases your size by one category from Medium to Large, for example. If there isn't enough room, you attain the maximum possible size in the space available. You gain advantage on strength checks and strength saving throws. Your magical weapons and equipment grow to match your new size. Melee attacks deal 1d4 extra damage.

Soul: Your soul assists you in your grapple by grabbing onto the soul of your opponent. For 1 minute you have the ability to initiate a grapple against creatures that are immune to the Grapple condition. In addition, any creature grappled by you is prevented from using any method of extra dimensional movement, including teleportation or travel to a different plane of existence.

Soul Clench

At 17th level, you learn to squeeze the life out of an opponent and force your own ki inside of them, slowing and weighing down their soul. When you succeed in a Grapple check you deal damage equal to your unarmed damage against that target. In addition at the beginning of your turn you may spend 2 ki and force a creature grappled by you to make a constitution saving throw. If it fails, it suffers one level of exhaustion; if it succeeds there is no effect.
