Path of the Brawler

A true barbarian fights not with his blades and hammers but with his own two hands and a whole lot of grit. Path of the Frenzied Brawler is a path that barbarians can take to harness the power of their fists and the untapped power within themselves.

Fists of Fury

Beginning at 3rd level you gain proficiency with unarmed strikes and fist weapons. Your unarmed strikes can be done using either Dexterity or Strength.  Your damage die for your unarmed strikes is a D8

At 10th level your unarmed strike damage die is a d10.

At 18th level your unarmed strike damage die is a d12.

The Ole One-Two

Beginning at 3rd level whenever you make an unarmed strike or fist weapon attack action you can use your bonus action to make an extra attack using an unarmed strike or fist weapon attack that had no damage bonuses to it.

Bob and Weave

Beginning at 6th level, you can use your reaction to expend a use of a hit-die in order to impose disadvantage on a melee attack made against you. If the attack then misses you, you can retaliate with an unarmed strike or fist weapon attack.

Focused Rage

Beginning at 10th level, whenever you go into a rage you instead go into a Focused Rage. While enraged, the character ignores any damage thresholds of objects he or she strikes. Attacks while enraged reduce armor class of your target by an amount equal to your strength bonus. Also, double your Strength bonus for the purposes of any Strength check made to break an object (including bursting bindings, such as ropes or manacles) or escape a grapple.

At 14th level you gain resistance against bludgeoning, slashing and piercing damage from non magical attacks when in a Focused Rage.

Knockout Punch

Beginning at 14th level, you can call for a non-lethal knockout attack using an unarmed strike or fist weapon.  When the attack hits roll damage, then roll half your level rounded up in d12s. If the roll is equal to the target's remaining HP the target is then rendered unconscious.  If the creature cannot be knocked unconscious it is instead stunned and knocked prone. You can use this feature once per short or long rest.

At 18th level you can use it twice per short or long rest.
