Path of Blood

The blood gods are not truly gods, but rather strong  entities that found their strength in the blood of other creatures. The blood of any creature holds part of their being and power, and the flowing of blood means an flowing of power. With this flow the blood gods gained in strength till they were powerful enough to imbue others with gifts. To increase their power they enlist others by enticing them with promises of strength, if they are willing to keep the blood flowing.

The blood gods generally have 3 types of servants; the bloodlust driven barbarians to serve as their main force, chosen by them from the most brutal of warriors; bloodthirsty cutthroats to serve as their assassins to take out specific threats, chosen from the most deadliest rogues; and blood cultists to show their power and entice more to become their servants, chosen from those without power that will go to any length to gain the blood gods patronage.

Having proven yourself a deadly warrior, willing to bleed and kill on the battlefield, the blood gods have come to you to offer you more strength to defeat your enemies. Their power comes with a price paid in blood, but this is a price you are more than willing to pay.

Blood of self

If you take slashing or piercing damage while raging, you can choose to not resist it (taking full damage).  The next time you deal damage while raging, you deal extra damage equal to half the damage you took. You cannot stack damage, only that last instance of full damage counts.

Blood of Others

If you reduce a creature to zero HP, you can choose to gain a number of temporary hit points equal to the damage you last attack did. 

Blood Rituals

You can preform a scacrificing ritual by carving runes into a creature and letting it bleed to death. This will take 10 minutes and you need a weapon that deals slashing or piercing damage and a creature that is unconscious or incapacitated. The ritual is painfull and the DM decides how the creature reacts (it can scream or try to get away or even attack). After the ritual is completed, you gain 1 of the following benifits:

- 1 extra Rage before your next long rest.

- You heal yourself or a ally within 10ft for 50 hit points.

- You get three moments where you can choose to deal maximal or minimal damage.

- You can ask for the location of a creature or person that the sacrificed creature has met. You get a short glimps of this creature or person at its current location and learn where this location is to within a mile.  Within 24 hours of the ritual, you can take 1 minute moments to concentrate to relearn the current location to within a mile, but you don't get a glimps by doing so.

You can only get each benifit once per long rest.

Blood Runes

As an action, you can use the blood of a creature you've killed to draw a rune on yourself. When you do you choose one of the following benifits:

- Choose 3 skills, you gain a +5 bonus to skill check with those skills. You loose all other bonusses and modifiers to your other skills except negative bonusses. 

- You gain a +2 bonus to your AC, but all your saving throws get -2.

- You gain a +2 bonus to your saving throws, but your AC gets -2.

- Your vision is unaffected by dim light or darkness (even magical), but you have disadvantage on all attack rolls and skill checks.

These benifits last until you finish a long rest and can not be discarded before that. You can only have one rune benifit at a time and aplying a new rune requires the blood of a creature that has not been used to draw a rune yet.
