Rather than focus themselves on the spiritual side of a monk's life, monks that follow this path have decided to focus on the more physical aspects of a monk's training. Grappler monks have immense control over their own bodies and have learned to manipulate their opponents' bodies in order to capitalize on specific weaknesses and pressure points. 

Physical Conditioning

When a character reaches 3rd level in this path has achieved extreme physical prowess when it comes to manipulating their own and other's bodies. The character gains proficiency in the Athletics and Acrobatics skills. 

Disabling Techniques

As a bonus action the monk may spend 1 Ki point to perform one of the following techniques against a creature they are grappling.

Arm Lock

The monk choses an arm on the creature they are grappling. The monk then performs an Athletics (STR) or Acrobatics (DEX) skill check, contested by the target's Athletics (STR) or Acrobatics (DEX). If the monk succeeds they are now grappling the creature by the chosen arm and the creature immediately drops any item held in the grappled arm.

Throw to Ground

The monk makes an Athletics (Str) skill check, contested by the target's Athletics (Str). If the monk succeeds, the target is moved to any square adjacent to the monk and is prone. 

Debilitating Strikes

 Starting at level 11 the monk may make a melee attack action and spend 1 Ki Point to perform any of the following strikes against a target they are grappling.

Groin Strike

The monk makes an Unarmed Melee attack roll versus the target. On a successful hit, the target takes damage equal to the Monk's Unarmed Strike and must succeed on a Constitution saving throw against the Monk's Ki Save DC or be Stunned for the next 1d4 rounds.

Maki Hiji Nagi (Elbow Break)

The monk must perform an Athletics (Strength) or Acrobatics (Dexterity) skill check, contested by the grappled target's Athletics (Strength) or Acrobatics (Dexterity). If the monk succeeds, the defending creature takes damage equal to the Unarmed Strike of the monk, and one of the target's arms are disabled until they rest for 10 days or receive magical healing. 

Thunderclap Strike

 The monk must succeed on a melee attack roll using Unarmed Strike against the grappled target. On a successful hit, the creature takes an amount of Thunder Damage equal to the Monk's Unarmed Strike Die, they must then succeed on a Constitution saving throw versus the Monk's Ki Save DC, or be Deafened for the next 1d6 melee rounds.

Submission

Starting at level 17 the Monk may attempt to force a target they are grappling into submission. They must succeed on an Athletics (Strength) or Acrobatics (Dexterity) skill check, contested by the target's Athletics (Strength) or Acrobatics (Dexterity). If the monk succeeds the creature is immediately Incapicated and must succeed on a Constitution Saving throw, versus the Monk's Ki Save DC, or become unconscious.

Alternatively, the Monk may expend 5 Ki Points to attempt to perform a lethal submission against the target. The monk must succeed on an Athletics (Strength) or Acrobatics (Dexterity) skill check, contested by the target's Athletics (Strength) or Acrobatics (Dexterity). If the monk succeeds, the creature must succeed on a Constitution Saving throw, if the creature has total Hit Points of 100 or lower, they immediately are killed, if they have more than 100 total Hit Points they take 10d10 bludgeoning damage. The monk must complete a long rest before using this feature again.
