Path of the Psycho

A psychopath is always advanced in his ways, in a sense. He will literally kill all.

Blood Bath

At level 3, whenever you kill a creature you enter Bloodlust for 3 turns. While in Bloodlust you gain a +10 to damage rolls and a -5 to attack rolls, also you heal for 1/3 the damage you deal. This becomes your new Rage option.

Fuel the Bloodlust

Beginning at 6th level, whenever you kill something in combat, your bloodlust lasts 6 more turns.

Strip the Flesh

At level 10, you can use your bonus action to rip a chunk of flesh from someone's neck. This requires a clash of strength checks. If you succeed, the target takes 1d12 Bleeding damage until the end of combat. If this drops the enemy to 0 Hitpoints, they fall unconscious. They will bleed out after 3 more turns if an ally doesn't use their action to heal them, requiring a medicine check with a DC of whatever you rolled, with your modifier, when rolling the strength clash to rip the chunk of flesh out.

If you fail the check, the target takes a single 1d6 of damage, one time.

 

Taste the Pain

At level 14, While in Bloodlust you gain resistance to Piercing, Slashing and Bludgeoning damage from non-magical weapons. You now have infinite Bloodlust after entering combat.
Starting at level 14, your Bloodlust lasts indefinitely until you exit combat. This starts when first rolling initiative. Also, at level 14 you lose your negative attack roll modifier.
