Path of the Titan

Some barbarians channel their fury into a bloody frenzy or a zealous wrath. Others unleash theirs like a beast from a cage, or a force of nature. You are none of them. Whether taught by a giant, a powerful warlord, or simply developed through years of combat, you found a new way to channel your savagery.

You hone your rage. Transform it into a shield of pure determination and might. You don't bend, you don't kneel, you don't fall. You are not just a warrior. You are a walking bastion. An army of one. A living weapon. You are a Titan.

Unbound

At 3rd level, you gain the following effects:

When you enter a rage, you grow in size as if under the enlarge effect of the enlarge/reduce spell. This effect is not a spell and does not use concentration. While under its effects, the enlarge/reduce spell has no effect on you. Additionally, your Rage damage bonus is doubled.

Unbreakable

At 6th level, your skin hardens to a stone-like durability. When you enter a rage, you get a bonus to your AC equal to your rage damage bonus, and temporary hit points equal to 1d12 + half your barbarian level, rounded down. Additionally, you gain resistance to bludgeoning, piercing, and slashing damage from nonmagical attacks, even while not in a rage.

Unyielding

At 10th level, you gain the ability to ignore exhaustion. Whenever you are about to gain a level of exhaustion, you can make a Constitution saving throw with the DC equal to 10 + half your barbarian level (rounded down). If you succeed, you don't gain a level of exhaustion. You can't use this ability again until you finish a short or long rest.

Unstoppable

At 14th level, you become the embodiment of physical might. Once per turn, whenever you hit a creature with a melee weapon while raging, you can cause this attack to deal the maximum amount of damage. You take the highest possible rolls on every damage die you roll for this attack. You can use this ability a number of times equal to your Strength modifier. You regain all expended uses of this feature after finishing a long rest.
