Way of the Bone Breaker

Monks who take the Path of the Bone Breaker are usually physically powerful warriors who have taken on additional training on how to break the bones of those who foolishly oppose them. A skilled Bone Breaker can cave in an opponent's skull, break an opponent's sword arm, and even drive an opponent's shattered ribs into their lungs. To a Bone Breaker, there are few things more satisfying than hearing and feeling the loud crack of bones breaking beneath the power of their grappling arms and strikes.

Iron Body

Having grown up a target of brutal bullies, many of your bones have been broken and have healed stronger. Your flesh bears a multitude of battle scars. Your hardened bones and toughened flesh make it much harder to hurt you. You've also learned to add your body weight to your strikes and grappling techniques..

Bone Breaker Technique

Skull Fracture

When you strike an opponent with a critical hit, or deal damage  greater than half the target's current HP, you cause a Skull Fracture. All of the target's actions are at disadvantage. If you strike this target with another Skull Fracture, the target must make a Death Saving Throw or be knocked unconscious.

 

Broken Ribs

When you strike an opponent with a critical hit, or deal damage greater than half the target's current HP, you break the target's ribs. All physical actions are at disadvantage. Target can make one less attack per round. Subsequent bludgeoning attacks deal an additional die of piercing unarmed damage as you drive the shattered bone fragments deeper into the target's body.

Bone Breaking Grappler

Broken Arm

When you  hit  with a critical hit or deal more than half the target's current HP, trap the sword or shield arm between your arms and break it. You also have the target grappled and can manipulate the broken limb with the weapon or shield trapped in place against the target on future attacks. When you do so,  you have advantage on your attacks and add an additional base unarmed die of damage to your unarmed attack damage. If the target attempts to use the broken limb, the unset bone tears through the arm, dealing your base unarmed damage to the target.

Broken Leg

When you hit with a critical hit or deal more than half the target's current HP, you break the target's leg. Grants advantage to attackers. Has disadvantage to attacks. Target is unable to take any actions that require the use of both legs. If chooses to move more than 5 feet, the unset Bone tears through the leg dealing your unarmed base damage to the target.

Improved Knockdown

Whenever you strike with an unarmed attack, or deal damage to a grappled target, Target must make an acrobatics or athletics check or fall prone. DC = the damage dealt + 1/2 your Character level.

Body Manipulation

At 15th level all opponents adjacent to you are considered grappled by you, gaining disadvantage to attacks and skills while granting advantage to those who attack them. Once per round you may use your reaction to redirect an opponent's melee attack to another target adjacent to you. You are never considered grappled unless the attacker has this ability.

Piercing Blows

Your unarmed damage ignores the resistances of all non legendary creatures.
