Path of the Elder Titan

The Titans once were the largest of the true giant races, standing even taller than cloud or storm giants. In the social order of giants, they were ranked highest on the Ordning, above all other giants, giant-kin, and ogres. Their strength was unmatched and those who follow in the path of the Titan try to emulate these feats. They wield mighty and powerful weapons, striking with enormous power. These barbarians are capable of near godly feats of strength and can shrug off some of the more deadly attacks. 

Will of Titans

Starting when you choose this path at 3rd level, you count as one size larger when considering your push, lift or carrying capacity.

While raging you count as one size larger when determining your push, lift, or carrying capacity so long as you maintain your rage.

While raging you may add your rage damage bonus to all strength checks and abilities. You do not loose your rage early so long as you make an attack roll or preform/maintain an athletics check to push, lift, or carry an object or maintain a grapple on a creature.

At 6th level Bludgeoning, piercing, and slashing you take from non magical weapons is reduced by a number equal to your Rage Damage bonus. While raging you can no longer be knocked prone by non magical means.

 

Siege Titan

Beginning at 6th level, you can muster destructive force with your assault. Battering even the toughest of creatures. 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. On a crit a creature of Large or smaller size must make a Strength Saving throw (DC 8 + your proficiency bonus + your Strength modifier) or be knocked back 10 feet and prone.

Enhanced Strength

At 10th level you can cast a form of enhanced ability on yourself without needing spell components or material components. Bear's Endurance: The target has advantage on Constitution checks. It also gains 2d6 temporary Hit Points, which are lost when the spell ends. Bull's Strength: The target has advantage on Strength checks, and his or her carrying Capacity doubles. Doing so does not require concentration and last for 10 minutes. Once you use this trait you cant do so again until you finish a long rest.

Titans' legacy

Finally at 14th level you become a force of nature that is unmatched in strength and endurance. At 14th level you can choose between the Titan's Might or Titan's Endurance feature during a short or long rest.

Titan's Endurance: When you enter your rage your current hit points and hit point maximum increases by an amount equal to twice your barbarian level. This increase last until the end of your rage but your current hit points do not decrease unless it is over your normal hit point maximum. Once you use this feature you can't do so again until a short or long rest.

Titan's Might: When you enter your rage, once per turn, you can take a -3 penalty to attack rolls. On a hit you can add an additional damage die to the attack.
