Path of the Executioner

While other Barbarians become frantic and frenzied, those who follow the Path of the Executioner kill with precision, and no remorse. They know the fastest way to the other side, and that is the end of their blade. As you enter the Blademan's Rage you become a one man judge, jury, and executioner. Where none shall escape your judgement. 

Those who tread this path may work with local governments, executing guilty criminals. Others take the law into their own hands, hunting down the undead and aberrations, and all others who may bring evil to this world. The worst of them all kill without reason, using their strength to leave a trail of blood in their wake. 

Blade's Judgement

Starting when you choose this path at 3rd level, you are able to deliver the killing blow on your target with expert precision. Once on your turn, while you are raging, you may attempt to execute a target. On this turn, you may only make one attack, regardless of features like extra attack or duel wielding. When you do so, if the attack hits, it is automatically a critical hit. If the damage from the strike reduces the targets hit points to less than your Barbarian Level + your Strength modifier, the target is instantly slain and your rage ends. You may use this feature a number of times equal to your proficiency bonus, regaining all uses after a long rest. 

Sense of Finality

You know the location of any creature that is bloodied (Below half health) within 60 feet of you, unless they are behind complete cover. When moving towards a bloodied creature you ignore all difficult terrain in your way. Additionally, you gain Advantage on Wisdom (Survival) checks made to track a wounded creature.

Final Moments

When you successfully execute a creature with your Blade's Judgement feature, you can choose one creature within 60 feet that can see you as your next target. The creature must make a Wisdom Saving Throw (DC 8 + Proficiency Bonus + Your Strength Modifier), or be Stunned with a sense of dread until the end of your next turn. 

While a creature is Stunned in this way you gain your movement benefit from your Sense of Finality feature. As well as your movement speed is doubled when moving towards these Stunned creatures.

Living Guillotine

Successful executions with your Blade's Judgement feature no longer end your rage. You also gain temporary hip points equal to half of the damage dealt on the creature you successfully executed.
