Path of the Grizzled Knuckle

A Barbarian of the Grizzled Knuckle has become so in touch with their primal energy that they no longer need to rely on the material world to effectively channel their Rage. These units of primal martial power can use their fists, legs, skull, or other body part of their choosing to deliver Unarmed Strikes with deadly force.

Barbarians who follow the Path of the Grizzled Knuckle learn the true potential of using their body as a weapon rather than a puny stick or sharp block of steel. Being able to use their Constitution to power their strikes makes them hardy, headstrong individuals who rarely back down from an opportunity to test their might. 

 

Level 3: Primal Pounding

You can add your Constitution modifier to the damage of your damaging Unarmed Strikes. Your Shoves deal your Constitution modifier in Bludgeoning damage to the target. You also deal Bludgeoning damage equal to your Constitution modifier at the start of every turn where you are grappling a creature.

Level 3: Double the Fall

Once per Short or Long Rest, when you use a Reckless Attack, you can add the target's Constitution modifier twice to the damage of an Unarmed Strike. This effect stacks with Primal Pounding.

Level 6: Forceful Blow

While Raging, your damaging Unarmed Strikes deal 1d12 extra damage. This can be either the damage type of the Unarmed Strike or Force damage.

Level 10: Primal Uppercut

You can use Double the Fall twice per Short Rest. Additionally, while Raging, your damaging Unarmed Strikes also gain the effect of the Shove Unarmed Strike (you choose to push the target or make it fall prone when they fail the saving throw).

Level 14: Reverberating Smash

While Raging, as an Action, you slam the ground with such ferocity that a 60 foot Line of concentrated Rage blasts forward. All targets within the Line must succeed a Constitution saving throw with a DC of 8 plus your Proficiency Bonus plus your Strength modifier. On a failed save, they are knocked Prone and take 6d12 Thunder damage. They stay standing and take half as much damage on a success. You can't use this feature again until you finish a Long Rest.
