Path of the Pugilist

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 snarling pack she swings wildly, knocking several hobgoblins off their feet and sending the rest scattering before her. The human braces himself for the impact as the orc rushes him. Then the monster 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, forcing 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 brandishes it before the noble. The young dandy 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, either from overconfidence or desperation. In a fight they can channel this strength of character to dig deep and fight off foes with greater strength of numbers, arms, or armour than anyone else would think possible.

Fisticuffs

At 1st level, your years of fighting in back alleys and taverns have given you mastery over combat styles that use unarmed strikes and pugilist weapons, which are simple melee weapons without the two-handed property, whips, and improvised weapons. You may not use the finesse property of a weapon while using it as a pugilist weapon. You gain the following benefits:

• You can roll a d6 in place of the normal damage die of unarmed strikes, whips, improvised weapons or barbarian weapons. This die increases as you reach higher levels, at 5th level the die increases to d8s then to d10s at 11th and d12s at 17th. 
• When you make an attack with a weapon that uses your fisticuffs damage die, you can make an additional attack as a bonus action. 
• You can now grapple as a bonus action

Street Smart

Starting at 3rd level when you take this archetype, your years of carousing, shadowboxing and sparring have paid off you. You are far more street smart than the common barbarian and gain proficiency in two additional skills from the Rogue skill list as well as a musical instrument or gaming set of your choice. 

Meat Shield

Beginning at 6th level, when you have an enemy creature grappled, you gain half-cover (+2 to AC and Dexterity saving throws) against all attacks made against you by a creature you are not grappling. When a weapon attack made by a creature you are not grappling misses you, you may use your reaction to have that creature make the same attack with a new roll against an enemy creature you are grappling with advantage. This only works with attacks that make an attack roll. 

Herculean

Beginning at 10th level, your carrying capacity is doubled, and when you deal damage with a melee weapon or unarmed strike to an inanimate object that damage is doubled. Your standing jump distance is the same as your running start jump distance. You can also now move unrestricted while grappling a foe or do a dangerous charge. If your movement consists of at least 20ft and ends in a throw or shove, the contested athletics check of shove is made with advantage and on a success, the target is instead pushed 10ft and knocked prone.

Unbreakable

Starting at 14th level, you gain an advantage on Strength, Dexterity, and Constitution saving throws. Additionally, whenever you are dominated, stunned, charmed, frightened or paralysed you can use a bonus action to end the effect.
