The way of the Bloody Knuckle is an unorthodox and brutal fighting style that often lacks the formal teachings or trainings of other monk paths. These monks rely on fast, decisive strikes and sure-footed evasion to dispatch foes efficiently and brutally. Warriors that follow this path often lack the traditions and formality of typical monks, instead unlocking their ki through self-determination and supernatural fighting instinct.

Old One-Two

Also at 3rd level, you learn to string unarmed strikes into devastating knockout combos. During your turn when you land two unarmed strikes in a row against a creature, you can
choose one of the following effects to impose on the creature:
The next attack against the target this round has +2 to hit
The target is deafened until the start of your next turn
The target is pushed 5 feet back if they are at most one
size larger than you
The target takes extra damage equal to your proficiency
bonus

Unstoppable Athlete

When you choose this path at 3rd level, you reach a level of physical fitness and raw strength unseen in most monks. You gain proficiency in the Athletics skill. Additionally, you may add your Wisdom modifier to Strength ability checks and saving throws.

Bob and Weave

By 6th level, your experience getting into scraps and brawls has taught you how to deftly avoid enemy attacks and then exploit their openness with brutal counterattacks. After a creature misses you with an attack, you can use your reaction to spend 1 ki point and immediately make a single unarmed attack against them. If this attack hits, it deals an additional Martial Arts die of damage.

Down But Never Out

By 11th level, you've become well accustomed to shaking off physical punishment and knockout blows. At the end of your turn, if you are stunned or unconscious you can spend 2 ki points to end the condition and gain temporary hit points equal to your monk level. If you have 0 hit points at the end of your turn, you can heal for 1 hit point. After you use this feature, your turn ends.
The cost of using this feature increases by 1 ki points each time you use it before completing a long rest, after which it resets to costing 2 points.

Unending Blows

At 17th level, your speed and aggression is unmatched, allowing you to throw out a constant stream of blows. If both of your hands are free, when you use flurry of blows you can make three unarmed strikes instead of two. Additionally, when using your Bob and Weave feature you can spend 1 additional ki point to make an additional unarmed attack as part of the same reaction.
