Black Blood[edit]

The child's back splits wide open, pouring a black fluid down and around him. The bandits are confused. Did the kid cut himself?

Before they can react, the blood, black as night, flows out under and pierces them, hardening into heavy black spires topped with their twitching bodies. As they breathe their last, the blood recedes like a tide, slithering back up into the child from whence it came. The child grins a deranged smile up at the night.

Class Summary[edit]

Black blood is a synthetically made and weaponized bodily fluid that coexists with the blood cells in the body. This virus of sorts grants immense resistance and strength. It, however, forces your character to lose sanity when in combat or dealing with intense situations. Black Blood was originally created by a witch known for her immense power and horrible ways to force her son into becoming an all-powerful creature. Based on the anime Soul Eater, the most notable character possessing Black Blood, Crona, was consumed by the madness from a combination of their blood itself, an experiment, and the torture endured from their mother.


Creating a Black Blood[edit]

When making a black blood, consider the following questions for your character: How did they come along this cursed power? Were they experiments, maybe? Are they in hardship with this consuming power? Do they let themselves go nuts or struggle and fight with themselves as they exist with it? Do they maybe even have a dual personality? Those with black blood can be assumed to have very odd and gruesome histories that make their personalities all the more unique and interesting. Keep that in mind during character construction.

Quick Build

You can make a black blood quickly by following these suggestions. First, Constitution should be your highest ability score, followed by Strength or Dexterity. When creating a black blood, you must remember to keep your buff abilities ready or active because you will be dealing damage to yourself as well as the enemy targets quite often.

On failure, they take 3d4 acid damage. You may use this feature twice, regaining use upon finishing a short rest.

Infused Weapon[edit]
