Path of the Titan

Barbarians that walk the Path of the Titan learn to control their rage rather than let it be their master.  A Titan’s power comes from intense physical training, resulting in what appears to be supernatural strength and will.   Many that attempt to walk this path are destroyed by the rigors of the training that they undergo, but those that survive learn to strike with unexpected fury and control.

Titan’s Ferocity

Starting when you choose this path at 3rd level, you channel your rage to make follow-up attacks more deadly.  When using a bonus action or reaction to make an attack, your rage damage bonus is tripled.

Will of the Titan

Starting at 6th level, your training gives you unparalleled endurance in battle.  You have advantage on Constitution saving throws while you are raging.  Additionally, whenever you succeed on a Constitution saving throw,  you can use your reaction to spend one Hit Die to heal yourself. Roll the die, add your Constitution modifier, and regain a number of hit points equal to the total (minimum of 1).  

Focused Rage

Starting at 10th level, on your turn you can choose to focus your rage on a single creature.   Your damage bonus from raging is increased by 2.  You gain an extra 20 feet of movement speed which can only be used to move towards the focus of your rage.  The effect lasts until the creature dies, your rage ends, or you attack another creature.  If you deliver a killing blow to the creature during the effect, you gain temporary hit points equal to your Barbarian level.  You may use this feature only once per short or long rest. 

Stunning Blows

Starting at the 14th level, whenever you score a critical hit on an attack against an enemy of equal size or smaller to yourself, the enemy must succeed on a constitution saving throw of DC 10.  On a failed save they are stunned until the end of their next turn.  Regardless of whether the target succeeds or fails the saving throw, this effect can only occur once per round.
