Path of the Unbreakable

You start to become the unstoppable object that you have wished to be, and gain abilities as such.

Rage-fueled Fists

Starting when you choose this path at 3rd level, You can roll a d4 in place of the normal damage of your unarmed strikes. When you Rage, your unarmed strikes deal an additional 1d4 damage.
Starting at 6th level, your unarmed strikes count as magical for the purpose of overcoming resistance and immunity to nonmagical attacks and damage.

Extreme Fortress

Starting when you go down this path at 3rd level, you may enter a guard state as an action. In this guard state you may not use movement or attack, but any damage you may take will be reduced by your constitution modifier + your current Rage Damage Bonus. You may exit this guard by using an attack action and replacing one attack with bringing down your guard. If you guard while in empowered rage you may move at half of your movement.

Empowered Rage

Beginning at 6th level, you may bolster the ferocity of your rage further. While you are raging, you may use a bonus action to empower your rage. While in empowered rage, damage you take is reduced by half your total Rage Damage Bonus (rounded down), and your melee weapon attacks gain an addition damage bonus equal to half of your Rage Damage (rounded down). Your unarmed strikes also deal an additional 1d4 damage while you are in Empowered Rage.

Unwavering Stance

When you reach level 10 in this subclass, while you are in combat, for every turn that you do not use movement and get hit, you gain a bonus to your next attack roll and the damage it deals. This bonus is equal to your current Rage Damage Bonus the moment you got hit.

Barrier’s Rush

Starting at 14th level, when you or a teammate within 10 feet of you is targeted for an attack, you may use your reaction to rush in front of them and take the blow instead.
