Way of the closed hand

Folowers of this path forsake the standard spiritual teachings of a monk to instead seek raw strength 

Upon takeing sub  class  at lvl 3 you lose acsess to all ki points but gain a new ability fistacuffs 

which alows you to gain improved crit, an extra atack (when unarmed), and gain an extra 1 d6 to youre martialarts damage, you can also now add str and dex to atack roles and damage 

At lvl 6 you get breaking strike(crits on an 18 or higer and on a hit (this abilit can only successfully activate once per turn) youre target must make a con save (dc is equal to youre strength score) or suffer a broken limb rendering them unable to use it (this effect can only be healed by a spell of 4rth lvl or higher and otherwise heals naturaly in a month) this effect always occurs on a critacle hit regardless of save)

At lvl 11 you gain improved fisticuffs (you gain an additional extra atack(with unarmed blows) and Youre d6 bonus from fisticuffs goes up to a d12)

At lvl 17 master fisticuffs (youre martialarts bonus from fisticuffs goes up to 2d12 You now gain an additional extra atack (with unarmed blows) and you now crit on a 17 )  

Ps if at at a given lvl a normal monk only gets ki related abilities instead take a abilitie score improvement or feat
