Sweet Science

(Meant to be used with it's own class, not a monk. I think it could still be fun, though.) Arrows rain down around her as she runs towards the hobgoblins. Desperate to close the distance, the half-orc fights through the sting of a dozen cuts to reach her foes. The pain only makes her stronger. As she descends on the hobgoblins she swings wildly, knocking hobgoblins to their feet and sending the rest scattering before her. He braces himself for the impact as the orc rushes him. Then the orc makes a mistake, telegraphing its next move, and that’s all the opening the human needs. He ducks beneath the orc’s wide swing then raises both hands high above his head and brings them down on the orc’s back, throwing the brute to the ground. The dwarf smiles broadly and chuckles as the petty noble raises his hand to strike him for the impudent remark. Quick as a flash the dwarf shatters the bottle in his hand against the bar and puts it between himself and the noble. The noble flinches, stumbles backward, and runs away as the dwarf turns back to the bar to order another round. Wherever they come from, pugilists live a rough and tumble life that leaves them full of determination and reckless from overconfidence or desperation. In a fight they can channel this strength of character to dig deep and fight off foes in greater strength of numbers, arms, and armor than anyone else would think possible.

Cross Counter

Starting when you choose this tradition at 3rd level, you can block the brunt of an attack and launch one of your own in the same fluid motion. You can use your reaction and spend 2 ki points to reduce the damage of a melee weapon attack made against you by 1d10 + your Dex modifier + your monk level. If you reduce the damage to 0, you can make an unarmed strike or monk weapon attack against a creature within range as part of the same reaction.

One, Two, Three, Floor

At 6th level, when you use your bonus action to use the Flurry of Blows, and both attacks are successful, you can immediately spend 1 ki point to make an additional attack with an unarmed strike as part of that bonus action. If you hit with this additional attack you deal no damage and the creature is knocked prone.

Float Like a Butterfly, Sting Like a Bee

At 11th level, when you reduce damage from an attack to 0 and successfully hit an enemy creature using your Cross Counter feature you regain 1 ki point.

Knock Out

At 17th level, when you hit with an unarmed strike or monk weapon you can spend 1 or more ki points to try to knock out the opponent instead of dealing damage. Roll 3d12 + 1d12 for every ki point spent after the first + your monk level; if the total is equal to or greater than the creature’s remaining hit points, it is unconscious for 10 minutes.
