Ichorbane

A creation of Oublivae, a powerful demon also called the Queen of Desolation, the ichorbanes' goal is to wander the planes in order to gather blood for their mistress.

An ichorbane is equipped with a large tank on their back that connects to one of its arms, which is filled with blood by means of an its probiscus. While the blood is for its mistress, it does not hesitate to use its supply to empower itself if it means gathering more blood than what it uses. It can even inject this blood directly into a foe's bloodstream, causing shock to their immune system.

Once its tank is filled, the ichorbane returns to its mistress in the 100th layer of the Abyss, known as the Barrens.
