Path of the Unbridled Fury

Barbarians who the Path of the Unbridled Fury are driven for the promise of sheer violence. It matters not what weapon you place in their hands, a barbarian of the Path of Unbridled Fury will find a way to cause maximum destruction with it.

You may not reduce your AC below 1.

Unstoppable Onslaught

Beginning at 6th level, you can continue the onslaught of your enemies when one falls. When you reduce a creature to 0 hit points while raging, you may choose to spend one of your unspent hit dice. When you do, you may move an additional 5 ft. and may make one additional melee weapon attack.

At 18th level the additional movement speed is increase by 5 ft. (for a total of 10 ft.).

If this point is occupied by a creature the creature is shoved 5 ft. away from you to an unoccupied space. At the end of your movement all creatures within 15 ft. of you must succeed on a dexterity saving throw (DC equal to 8 + your proficiency bonus + your Strength modifier) or take damage equal to a roll of your weapons attack damage. On a success creatures take half damage.
