Path of the Rageborn

Born from the fiendish plane known as the Iron Wastes, the rageborn are creatures that embody unadulterated wrath.  The great demon prince, Kostchtchie, fills the ranks of his demonic army with these fiends to create one of the most dangerous fighting forces in the Abyss.  Barbarians that channel this path draw influence from these avatars of unbridled rage and relinquish their control over their rage.  They embrace the wildness of their ire and give into the recklessness of its drive.  This immersion turns these warriors into hellish savages on the battlefield and inspires their compatriots to engage in the brutality.

Savage Revelry

Lash Out

Beginning at 10th level, you strike at the nearest threat whenever something tries to stop you.  Whenever a creature tries to Grapple you or you are forced to making a saving throw to avoid being restrained, knocked prone, or shoved, you can use your reaction to make melee weapon attack against a creature within 5 feet of your location.  This attack can be made recklessly. 
    Additionally, any opportunity attacks that you make can now be made recklessly.

Aggressive Proliferation

Starting at 14th level, whenever you hit a creature with a reckless attack, friendly creatures that can see you can use their reaction to make a melee weapon attack creature within their reach.  The attack is made with advantage.
    Additionally, your brutal blows leave an injured foe off-balance and exposed.  Whenever you critically hit a Large or smaller creature, it is knocked prone and suffers vulnerability to the next damaging melee attack that it receives.
