Path of the Pursuer

Someone somewhere has brought about judgment, and after festering inside you, your rage has finnally boiled over with a singular purpose Vengeance.

This is a single target barbarian sub class focused on chasing down and killing a specific creature that has wronged you and become the object of your rage.

Focused Rage

Starting when you choose this path at 3rd level, you can focus down a target when you enter your rage. The target must be within 30 feet of you when you enter your rage and it remains your target for 10 minutes, until your rage ends, until you fall unconscious or until the creature dies. You cannot nominate another target until you enter another rage.

While your are focused on your target, you gain advantage on attack rolls you make against that creature each turn, and you know the distance and in what direction that creature is from you, however you have disadvantage against any other target on the battlefield until your target is dead.

Relentless Pursuit

Beginning at 6th level if the target of your rage is in sight and further than 5 feet away you may use a bonus action to move your speed towards your target. This movement provokes attack of opportunity, but may not be hindered by difficult terrain or magical slowness.

Additionally, if your target is in sight and further that 5 feet away and you are grappled by a creature other than your target you may use your bonus action to attempt to escape the grapple.

Fortified Mind

At 10th level you fortify your mind in the pursuit of your target.
You gain advantage on wisdom saving throws made against spells that attempt to charm you or mind control you.

As well as this, whilst raging, whenever you succeed on a Wisdom saving throw due to a creature casting a spell against you, that creature suffers Psychic damage equal to twice your rage damage bonus.

Ain't Got Time to Bleed

Starting at 14th level, your need for vengance surpasses your bodies mortal limits. While you’re raging, having 0 hit points doesn’t knock you unconscious if your target is still alive and in sight. You still must make death saving throws, and you suffer the normal effects of taking damage while at 0 hit points. However, if you would die due to failing death saving throws, you don’t die until your rage ends, and you die then only if you still have 0 hit points.
