Blood Rager

Coming originally from fanatic abbysal cultists who traded the blood of enemies for strength and power. They will often capture as many as they can to trade them to gain powers full of blood draining rituals most prefer death to being captured by blood ragers. Any crazed cultist can drink blood and deal with dark powers but most are not Blood Ragers for they are the rare few that initiated the deal and the idea. Most are those that have made a deal with a higher power to trade blood and others vitalities for power while others have inherited it from family members who made the deal and the demons seeing it as their job to continue the deal. Given a thirst for blood and hunger for flesh by their dark patron they will kill any who fight and sacrifice the rest.

Blood Drink

When you reach level 3, you can make a bite attack while in a rage (1d4 + str mod unless you have a bite attack from another source) as an attack action once per turn you gain temporary hit points equal to your con mod that last while you are enraged and fade when your rage ends it also ends if you are charmed/stunned/frightened while you have any temporary hitpoints (this can be stacked up to 10 times) any creature that has no flesh and blood gives no temp HP (i.e. Skeletons, Elementals, most constructs)

Abyssal Pact
