Path of the Primal Rage

same as above

Primal Rage

Starting when you choose this path at the 3rd level when you enter your rage, the anger, regret, and pride of previous barbarians fills you. You become resistant to all damage types except psychic and radiant. 

Relentless Warrior

Beginning at 6th level, while raging you may use your bonus
action to make a single melee attack. When your rage ends
you must make a CON Save equal to 9 plus half your level
rounded up or suffer one level of exhaustion and have your
movement speed reduced by half until the exhaustion ends.

Rage Manifest

Beginning at 10th level, your rage manifests around your weapon in a design you choose. Your attacks now count as magical in order to overcome resistance to non-magical attacks. 

Rage Release

Starting at 14th level, you now crit on a 19 or 20 when rolling your D20. When you do so, roll double the normal damage die before doubling the total for the critical hit. (If normal is 1D12 roll 2D12 then double)
