Brawler

When the brawler enters a fight, they need no sword or knife to defeat their enemies. They always carry with them the weapons the gods blessed all men with: fists. Calloused, hardened, and brutal, the brawler’s fists split flesh, shatter bone, and pulverize organs with blinding speed and devastating accuracy. At the same time, the brawler learns the simple truth of combat: you must accept blows if you wish to deliver them. The brawler learns to laugh at pain, accepting a hit to earn a chance to land the knockout punch.

Pugilist

At 3rd level, you are always considered armed with a melee weapon. Your unarmed attacks deal 1d8 points of damage plus your choice of Strength or Dexterity modifier. This damage increases to d10 at 10th level and d12 at 18th.

In addition, when you make an unarmed opportunity attack against a provoking target, you deal an additional +1d4 points of damage.

Hammer Fist

At 7th level, whenever you deal a critical hit with your unarmed attack, the target also must make a Constitution saving throw with a DC equal to 8 + your proficiency bonus + your Strength bonus or fall prone.

In addition, your unarmed strikes count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Knockout Punch

At 10th level, you can attempt to deliver a knockout punch on an attack action. This punch strikes the opponent so hard it could possibly knock them unconscious. The target must make a Constitution save equal to 8 + your proficiency bonus and Strength bonus or become unconscious until they can make a successful save. You cannot knock out a target of larger size than yourself. You can attempt this ability once per short rest, but you gain an additional use at 15th and again at 18th level.

Hand to Hand Mastery

At 15th level, add half your proficiency bonus as bonus damage to all unarmed attacks. In addition, your unarmed attacks deal critical hits on a roll of 19 and 20.

Stonejaw

At 18th level, you gain resistance to all bludgeoning damage, including magical weapons attacks.
