Path of The Reaver

A true Reaver has tasted the ritually prepared blood of a dragon. It is more than a state of mind. These fearsome warriors revel in death, regaining energy from the suffering of their foes.  Reavers terrorize their enemies, feast upon the souls of their slain opponents to heal their own flesh, and can unleash a blood frenzy that makes them more powerful as they come nearer to their own deaths.

The Reaver trades pain for strength in a constant balance of selfish sacrifice. At first it seems that Reavers are doing the work of their enemies, damaging themselves in gruesome fashion. But Reavers can transform their own living essence into raw damage, and then replenish that health by stealing the life from their foes. It's a dangerous gamble that counts on added strength to destroy enemies before incoming attacks or the Reavers' own abilities kill them. The closer they are to their own deaths, the more efficient they are at inflicting the same on others.

Aura of Pain

Starting at 3rd level, you emanate a aura of pain while you rage. The aura extends 10 feet from you in every direction, but not through total cover. Your aura has an effect that activates when you enter your rage and at the beginning of each of your turn that you are raging. When this effect is activated, ALL creatures in your aura take 2 psychic damage each. The damage increases when you reach certain levels in this class, increasing to 3 at 5th level, 4 at 10th level, 5 at 15th level, and 6 at 20th level. You take the same amount of damage. Your Aura of Pain can't bring you below 1 HP.

Additionally, the closer you get to your own demise, the harder you hit. While raging, for each 20 hit point missing form your maximum health you deal 1 extra damage on your next melee attack. You can deal this bonus damage only once per turn.

Devourer of Pain

At 6th level, The painful death of your enemy can mend some of your wounds allowing you to fight longer. 

While raging, if a creature hit points drop to 0 in your aura you regain 1d6 + your barbarian level in temporary Hit point. You can benefit from this healing only once per turn and those temporary hit point stay for the duration of your rage. Every Temporary hit point left are lost at the end of your rage.

 You regain 1d8 + barbarian level at 5th level, 1d10 + barbarian level  at 10th level and 1d12 + barbarian level  at 15th level

Awakening Pain

At the start of your turn, while you are raging, you can remove one of those condition that are affecting you as a bonus action. Those condition are: Charmed, frightened, paralysed and stunned.

Painful Rebirth

At 14th level, if you are using the ''relentless rage'' feature you have advantage on the CON saving throw that it allow. Then regardless of the result, you may move up to half your speed to make one melee attack.

Once you fail a CON saving throw as part of using the ''relentless rage'' feature you can't use the ''painful rebirth'' feature until you finish a short or long rest.
