Path of the Reaver

For the warrior who exalts in death, there is the Path of the Reaver. As a reaver, you gain power and adrenaline from taking on attacks head on and causing your foes to fall. You thirst for death, even becoming stronger as near it yourself.

Adrenaline

Beginning when you choose this path at 3rd level, your attacks have the potential to be absolutely devastating when you smell blood. While raging, you gain adrenaline when you bring an enemy to 0 hit points, score a critical hit against an enemy, or have a critical hit scored against you. One you have adrenaline, you cannot gain it again until you have expended it. In other words, you cannot accumulate stacks of adrenaline. When your rage ends, you lose the adrenaline.

While raging, you may expend your adrenaline as part of a melee attack roll using Strength. If you hit, you may reroll each damage die which shows its maximum possible result and add the new roll to the original total. you continue to reroll such dice until each die shows less than its maximum result, appending to the total each time.

Devour

Starting at 6th level, you can use your adrenaline as part of an attack to regain hit points equal to the damage you deal. You may use this ability 3 times, after which must finish a short or long rest to regain these uses.

Bloody Appetite

At 10th level, if you have adrenaline when your rage ends, you regain one expended use of Devour. In addition, you may use Devour without regard to your uses remaining as long as your current hit points are less than one quarter of your maximum.

Bloodfilled Rage

Beginning at 14th level, the smell of blood fuels your rage allows you to shrug off 

While you’re raging and you have adrenaline pumping through your veins you are immune to crowd control effects such as being charm, paralyze, and slow. Also, when you gain hit points from Devour you may also add your Constitution modifier to the hit points healed.
