Elemental, Blood

A swirling, bubbling, ambulatory glob of blood the size of a hogshead cask lurches forward. Native to a lake of churning blood from another dimension, blood elementals aren’t typical elementals.

Blood mages seem able to retain tiny blood elementals as familiars or guardians of some kind, though the exact nature of their bond is a mystery they guard jealously. Many small sects of blood cultists seem to learn the secret, leading some savants to believe that this knowledge is freely shared by priests of a blood cult.

Drawn to Life
A blood elemental is drawn to movement and absorbs whatever living creatures it finds, increasing its size and power in the process. Though feeding is not necessary to sustain themselves, blood elementals, over time, will shrink unless they consume living creatures. However, their need for prey is relatively slight—once a week to maintain their size.

Blood Summoning
Offerings of blood and blood magic spells draw blood elementals from their transdimensional homes, with the proper ritual. They also sometimes follow in the wake of certain demons and devils, devouring entire bodies in a matter of hours.

When a blood elemental feeds, it first removes all liquids, then liquefies and consumes the remaining flesh, and finally sucks out the marrow, leaving behind only dry, reddish bones.

Elemental Nature
The blood elemental doesn’t require air, food, drink, or sleep.
