Rager

Less a commentary on how primitive or base their techniques are, these berserkers instead personify the essentials of the trade: dealing death and coming back from the brink of it themselves. From a rough-and-tumble highway bandit to a sophisticated royal guard, this sort of berserker is the one most commonly encountered.

Hard to Kill

Starting at 3rd level, you tap into a ferocious sort of vitality. When you are reduced to 0 hit points or less you can immediately make a death saving throw . On a success, you instead gain a number of hit points equal to your Constitution modifier and do not lose the benefits of your rage. Once you have used this feature, you can’t use it again until you finish a short or long rest .

Enraged Focus

Also at 3rd level, your fury brings your enemies into sharp clarity. While you are raging, you gain an expertise die on your first attack each round.

Thirst for the Kill

Starting at 6th level, you find that you revel in the destruction you wreak. When you reduce a hostile creature to 0 hit points, you gain a damage bonus equal to that creature’s Hit Die to apply on your next successful weapon attack made in the next minute.

Relentless

Starting at 10th level, if a creature uses the Disengage action to leave your reach while you are raging, you can use your reaction to follow them a number of feet equal to double your Speed. You can use this feature a number of times equal to your proficiency bonus and regain all expended uses when you finish a long rest .

Pitiless Gaze

Starting at 14th level, when a creature within 5 feet of you hits you with a melee attack while you are raging, the attacker takes 1d6 psychic damage as they quail before your raw fury.
