Path of the Fist

For some barbarians, rage is a means to an end – the end of your fist. The Path of the Fist  is a path of untrammeled fury, slick with blood on your knuckles. As you enter a rage, you thrive in battle, heedless of your own health or well-being.

Unarmed Fighting

You gain the Fighting Initiate feat specific to Unarmed Fighting.  In gaining this feat, you forgo the use of proficiency on any Melee Weapon attacks. 

Combination Swings

Starting when you choose this path at 3rd level, you can focus on combination strikes when you rage. If you do so, for the duration of your rage you can make a single uarmed strike as a bonus action on each of your turns after this one.

The Zone

Beginning at 6th level, you can’t be charmed or frightened while raging. If you are charmed or frightened when you enter your rage, the effect is suspended for the duration of the rage.

Haymaker

Beginning at 10th level, you can use your action to put your entire body into a single unarmed strike.  Make an unarmed attack roll against a creature within melee distance and if it connects, the target must succeed on a DC 16 Constitution Saving throw, becoming stunned if they fail the save.  The damage for this unarmed strike is 2d8 + your Strength modifier.

You can use this feature a number of times equal to your Proficiency modifier and regain charges on a long rest

Counter

Starting at 14th level, when you take damage from a creature that is within 5 feet of you, you can use your reaction to make an unarmed attack against that creature.
