Path of Blind Fury

"In the ruins of the destroyed houses, a figure pushed itself out of the rubble, a greataxe in hand, body built like an ogre. Despite the rocks and jagged pieces of wood, the figure looked barely scratched. It was a man, his eyes cold and his demeanor threatening. His stare locked to the hulking mass of the demon but 40 feet in front of him. It was a surprise to the surviving citizens that he was alive, even more so when the man grinned. A maniacal grin, soon followed by a furious face, closely mimicking the fiends expression. In a small time window, he closed distance with the monster, his greataxe lifted above his head. In a single, destructive blow, the man sinked his weapon through the aberration's "shoulder". To complete shockof the surrounding crowd, the creature showed fear, and terror to the man. In desperation, it bit at the man, barely managing to pierce the man's torso. The pain flowed through the barbarian, enraging him to an even heightened point. With a loud, terrifying roar, the man raised his axe once more, and the creature didn't last long after that, the sound of the axe hacking and slashing through it repeatedly until nothing was left."

Rampage

Starting when you choose this path at 3rd level, when entering a rage, you can choose to start a Rampage. During a Rampage, you roll a d20 at the start of each of your turns. If that roll is a natural 1 or 2, you will attack the closest creature (including allies and neutral creatures) to you. If no creatures are near (including allies and neutral creatures), the Rampage ends. While in a Rampage, you deal an additional damage die respective to the weapon used.

Also, if you kill a creature in a Rampage, you can use your Reaction to move half of your movement instantly, and make a single attack to a creature.

Beast

Beginning at 6th level, once you hit a creature with a melee attack, you can instantly make an attempt to grapple the target.

Monstrosity

Beginning at 10th level, when you score a critical hit on a target, you can force all creatures within 10ft (including allies, neutral creatures and the hit creature) to make a Charisma Saving throw, or else become frightened. If the critical hit kills the creature, the saving throw made has disadvantage.

Abomination

Starting at 14th level, the pain you suffer drives your power. During a Rampage, for every 20 hitpoints of damage you take allow you to deal an additional d4 damage to your next attack. The amount of dice you can stack is equal to your constitution modifier.
