Path of the Blood

In some occasions, somebody who has been influenced directly or indirectly by dark powers goes through a radical macabre physical mutation. Sometimes, these mutations can go out of control, creating creatures powered by blood, somewhat similar to a vampire. Part of these individuals who dedicate themselves to the art of battle and warfare often find themselves becoming a violent, bloodthirsty and mindless warrior. In the majority of cases these warriors end up dead for a variety of reasons, most of them of violent nature, but there has been cases of this beings attaining control over their bloodlust.

Fueled By Blood

Your mutations allow you to absorb fresh blood. While in Rage, when taking the Attack action you can force the targeted creature to make a Constitution Saving Throw, the DC of which equals 8 + your proficiency bonus + your Constitution modifier, if the enemy fails you absorb his blood and gain +1 to Strength or Constitution Score (your choice). Once you have obtained 2 Extra Points in total using this feature you become Blood Crazed, gaining the following benefits:

• Resistance to all damage.
• Double Rage Damage.
• Rage doesn't end until 1 minute has passed.

When you become Blood Crazed make a DC 13 Wisdom saving throw. If you fail, on your turns you automatically attack the closest most vulnerable creature, failing to discern allies from enemies, in this state you cannot be charmed nor frightened. Repeat the saving throw at the end of your turn until you succeed, regaining control over your senses. If you receive Extra Score Points after becoming Blood Crazed, you must repeat the Wisdom saving throw, the DC becomes 13 + Total Extra Score Points. The boost to the the scores disappear when your Rage ends. 

At 10th level,  when you become Blood Crazed you also roll crits on a 19-20.

Eldritch Analizer

By consuming any amount of blood, you can learn a creature's Constitution and Strength scores, gender, race and if its a spellcaster. In addition, in a range of 3000 feet, you know the approximate location of the tracked creature for 5 minutes. You can extend the duration of this feat by consuming more of the same blood. Consuming other creature's blood overwrites the focus of the tracking capabilities of the Barbarian towards the new blood.

Sanguine Energizer

As a bonus action, you can give up a Hit Die to fill a small vial of your own blood. When an ally drinks It, he heals for 1d12 + your barbarian level, if you drink It you can choose either the heal, or become Blood Crazed. If you chose to become Blood Crazed skip the initial Wisdom Saving Throw.

You can use this trait to heal a number of times equal to your proficiency bonus.

Once you used this trait to become Blood Crazed you cant use It again until you have finished a long rest.

 

Bloody Resilient

When Blood crazed, if you drop to 0 hit points  you can give up your Blood crazed status to drop to 1 hit point instead.

You can use this trait a number of times equal to your proficiency bonus.
