Base Class: Barbarian
As a Crimson Rage barbarian, you feed from the pain and anguish suffered in combat to inflame your rage. The shared blood of vengeful, ancestral spirits burdens your heart with a murderous lust quenched for a brief moment when your blade bites skin.
Blood Rage
Starting at 3rd level, you can inflict a wound upon yourself as an offering to the blood god, dealing 1d12 damage to self while you are raging, as a reaction you may activate blood rage damaging your self, causing your eyes and mouth to leak blood. You choose a creature you can see within 15 feet, marking them as the target of your rage. Until your blood rage ends, you deal an extra 1d12 damage to the target whenever you hit it with a melee weapon attack. If the target drops to 0 hit points, or you attack a creature other than the target, the blood rage will end. Blood rage last for 1 minute, and counts as magical damage for the purpose of game mechanics.
You can Blood Rage an amount of times equal to half your proficiency bonus rounded up, and at level 15 you can now blood rage an amount of times equal to your proficiency bonus.
Also at 3rd level, gain one proficiency with an Intelligence, Wisdom, or Charisma Skill.
Crimson Hunger
Also at level 3, While you are raging whenever you deal melee damage to an enemy creature, you must roll a d20 that can not be affected by any outside effects, if you roll above a 10 you can siphon blood from your enemy and heal your self by 1d4. This effect can only happen once per round, and resets at the start of your next turn. (If you succeed you don't need to roll anymore on landed attack rolls.)
The self heal you receive gains an additional 1d4, at levels 5, 8th, 12th, 17th, and 20.

Bloodport
At 10th level, If you ever get hit by a critical attack, after taking the damage you may as a free action teleport up to 25 feet away from the target in any direction, as long as you can see the point you are traveling to, also if you fall to zero hit points you may activate this ability.
If you fall to zero hit points and you have blood tendrils activated you may before you teleport away, use your reaction to have your tendril attack the creature that hit you if it is within range. If you hit you deal the normal damage that the tendril deals and you get to heal your self by the amount you roll on a d20, causing you to come back to consciousness after you teleport away. If the attack by the tendril happens to kill the creature you instead drain all the blood inside the creature and heal your self for 2d20's.
This ability can be used once per day and resets after a long rest.
Blood Tendrils
At 14th level, As an action you may grow two blood tendrils from your back while your in rage mode. This ability last as long as you are in rage. While your in tendril mode you can use your bonus action to attack up to two targets at once, they must be at least 10 feet from you in any direction, and as one bonus action you may make two attack rolls at once, either both at one creature or at two different ones. The blood tendrils deal 1d8 of slashing damage + your constitution mode + your charisma mode, and if a creature is killed by a tendril your tendril drains there body of blood leaving them an empty sack, and granting you 1d10 + 2 temporary Hit points.
You can do this ability twice per long rest, and at level 20 three times for long rest.
