Juggernaut barbarians are siege engines in their own right, able to stand their ground and move their foes into positions of weakness. While raging, they make any battlefield their domain, shoving foes over mountainsides and destroying even the strongest structures with their attacks.
Source: Tal'Dorei Campaign Setting
Starting when you choose this path at 3rd level, your rage instills you with the strength to batter around your foes, making any battlefield your domain. Once per turn while raging, when you damage a creature with a melee attack, you can force the target to make a Strength saving throw (DC 8 + your proficiency bonus + your Strength modifier). On a failure, you push the target 5 feet away from you, and you can choose to immediately move 5 feet into the target’s previous position.
You harness your fury to anchor your feet to the earth, shrugging off the blows of those who wish to topple you. Upon choosing this path at 3rd level, you cannot be knocked prone while raging unless you become unconscious.
Beginning at 6th level, you can muster destructive force with your assault, shaking the core of even the strongest structures. All of your melee attacks gain the siege property (your attacks deal double damage to objects and structures). Your melee attacks against creatures of the construct type deal an additional 1d8 weapon damage.
Upon reaching 10th level, you wade into armies of foes, great swings of your weapon striking any who threaten you. When you make a weapon attack while raging, you can make another attack as a bonus action with the same weapon against a different creature that is within 5 feet of the original target and within range of your weapon.
Starting at 14th level, you can choose to become unstoppable when you enter a rage. If you do so, for the duration of the rage your speed cannot be reduced, and you are immune to the frightened, paralyzed, and stunned conditions. If you are frightened, paralyzed, or stunned, you can still take your bonus action to enter your rage and suspend the effects for the duration of the rage. When your rage ends, you suffer one level of exhaustion.
