Path of the Bloodletter

The path of a Bloodletter is one few dare to traverse, few come back after giving into the bloodlust. Bloodletters are an never ending duet of fury and bloodshed, the splattering of blood is music to their ears, the song only ending when either they, or their enemies, have fallen. Bloodletters specialize in running headfirst into battle dealing deadly blows and gaining tenacity through the death of foes.

Blood Frenzy

Starting when you choose this path at 3rd level, on a successful attack action you gain an additional effect while raging. If wielding an off-hand weapon you may make an attack roll for free using your off-hand weapon or/otherwise gain an additional weapon damage die. Does not apply on bonus actions or reactions.

Unstoppable Rage

Beginning at 6th level you may Dash as a bonus action. While raging you aren't affected by difficult terrain, magical or non-magical, and can’t be charmed or frightened. If you are charmed or frightened you may enter a rage to end its effect.

Tenacious Bloodlust

Starting at 10th level, when a creature within 10ft of you gets reduced to 0 hit points while raging, you gain temporary hit points equal to your Constitution modifier + your Barbarian level (minimum of 10). When your rage ends you lose all temporary hit points gained from this effect.

Unrelenting Fury

Beginning at 14th level, while raging you've learned to harness your fury into a deathblow. On your turn you may use your action to guarantee a critical hit. If this attack kills the target all hostile creatures that can see must succeed a Wisdom saving throw (DC equals to 8 + your proficiency bonus + Rage Damage) otherwise they are frightened. At the end of each of the frightened creatures turns, it must succeed on the same Wisdom saving throw or remain frightened. On a successful save, the condition ends for that creature.

Once you use this feature, you are unable to use it again until you finish a short or long rest.
