This gaunt creature is humanoid in shape, except for two long, writhing, pale tentacles that sprout from beneath its arms. Although its features are somewhat goblinoid in appearance, wicked talons cap its long, spindly fingers, and its wide maw opens to reveal many sharp teeth, including six 6-inch-long fangs. Its hairless, gray-skinned body is covered in oozing sores that weep a pale white fluid.

A truly repulsive creature, the bonedrinker hunts to feed on the bones of its victims. Terrible undead created in a horrid ritual reminiscent of mummy creation, bonedrinkers wander the dark places of the world, seeking new creatures to feed upon. Hobgoblin wizards originally developed the ritual to create these monstrosities, using the fallen corpses of goblin and bugbear warriors to create the first lesser bonedrinkers and bonedrinkers. The tradition of using bugbears and goblins became habit, and nearly all bonedrinkers previously lived as one of these two goblinoid races. In theory, other humanoid creatures could be converted into bonedrinkers, but this would require twisting and adapting the original ritual.

Bonedrinkers resemble ghasts in many ways, leading those who catch only fleeting glimpses of the creatures to erroneously pass on exactly that description. If it weren't for the two tentacles that grow beneath their arms and the six horribly long fangs in their mouths, the description might even fit.

A bonedrinker's body is covered in weeping sores, the result of its constant need to feed. The longer one goes without liquefying and draining a creature's bones, the more sores appear. This has no effect on the creature's abilities, but a bonedrinker certainly grows more reckless and desperate the hungrier it becomes.

Bonedrinkers prey on any creature with a skeletal structure. They care nothing for vermin, elementals, constructs, or any other creature lacking their favorite food. Many other carnivores similarly eat bones, but not in the same way that a bonedrinker does. Bonedrinkers secrete a strange chemical in their saliva that breaks down bones into a viscous liquid.

As the bones liquefy, the bonedrinker slurps them up through wounds it inflicts with its bite. In essence, a bonedrinker is to bones what a vampire is to blood.

A bonedrinker stands about 7 feet tall and weighs roughly 225 pounds. Created from a bugbear, it superficially resembles the goblinoid from which it was created.

Bonedrinkers speak the languages they knew in life, typically Goblin, and that of their creators, typically Goblin and Common.
