Path of the Demon Guardian

These barbarians appear slow and cumbersome. Don’t let that fool you -- they possess the strength of a giant and an indomitable will. It takes incredible fortitude to be the guardians of your people. You must defend them at all costs and put their needs above your own. This has never been an issue for those who follow the path of the Demon Guardian. The greatclub is an unreasonable weapon; clumsy, dangerous... unless you possess the strength of a demon and an unbreakable will

Demonic Strength

Your size is large. Starting when you choose this path at 3rd level, you roll 3 dice when making strength checks or saving throws while raging, as opposed to 2.

Crashing Thunder

Beginning at 6th level, while raging you can use your bonus action to move up to 40 feet in one direction, moving at least 10 feet. You can attempt to move through the space of creatures that are no more than one size larger than you, forcing them to make a strength saving throw with a DC equal to 8 + your CON modifier + your proficiency bonus. If the creature succeeds, you are stopped and the creature can make an opportunity attack against you. If the creature fails, they are knocked prone and get no opportunity attack.

Unstoppable Attacks

Starting at 10th level, while raging you can choose to make one attack on your action instead of two. Attacking in this way adds 10 to both the hit roll and to the damage roll for the attack. An attack you choose to make unstoppable can not also be made reckless.

Demon's Embrace

Starting at 14th level, you can grapple a creature while raging to entrap them in a deadly embrace. The creature takes 1d6 + your STR modifier in bludgeoning damage, and you heal for half the damage dealt. For every 10 HP you are currently missing, add 1d6 to the damage of Demon's Embrace. The grapple then ends. You can use this ability a number of times equal to your proficiency bonus.
