Homebrew Blood fiend Species Details
Bloodfiends have two main origins, the older of which being those who received blood in a "certain mansion." These Bloodfiends have adopted an intense hierarchy based on the degree of separation from their original progenitor. Despite not being related in the traditional sense, they refer to each other with familial terms. More specifically, those who were turned by the original progenitor have each distinguished their "Children" and "descendants" as their own Family. Each Family has settled into a different Nest and taken it as their territory, and "culled their kin" until they were able to live quiet lives. However.
Bloodfiends are nearly identical to ordinary people most of the time. The most obvious indicator is the black and red patterned crystalline growths that can appear during combat, usually on one half of the face. All Bloodfiends have red eyes; however, red eyes are not a surefire indicator of a Bloodfiend, as the color can be produced or modified. Additionally, people may not be consciously aware that they are Bloodfiends: Bloodfiend behavior may only emerge at night when they are sleeping, or under more specific conditions.
Bloodfiends are additionally defined by a persistent desire for blood. Although Bloodfiends only require a minimal amount of blood for survival, the mental state of most Bloodfiends relies heavily on a steady source of freshly-drawn human blood, with even the most strong-willed of them becoming more on edge, if not going outright insane over long periods of abstinence. Abstinence also appears to cause general weakness and withering. Notably, certain Bloodfiends, are able to mostly or completely negate the effects of abstinence, likely as a result of fixating on a "purpose" to live for.
Most Bloodfiends also have an irrational fear of water, though those of an high enough generation have the ability to overcome this phobia.
Blood fiend Traits

Bloodfiends have a large degree of control over blood, being able to shape it into weapons, armor, or even architecture by crystallization, as well as being able to draw it directly to themselves from their Bloodbags and Kindred. While most Bloodfiends seen use physical gestures to wield their blood-based powers, whether by necessity or as a simple flourish, shows that, at the very least, Bloodfiends of an early enough generation are able to do so while barely moving a finger.

Languages
Your character knows at least three languages: Common plus two languages you roll or choose from the Standard Languages table. Knowledge of a language means your character can communicate in it, read it, and write it. Your class and other features might also give you languages.
The Standard Languages table lists languages that are widespread on D&D worlds. Every player character knows Common, which originated in the planar metropolis of Sigil, the hub of the multiverse. The other standard languages originated with the first members of the most prominent species in the worlds of D&D and have since spread widely.
