Bloodthorn vines, also known as vampire vines[4] or vampire thorns,[3] were a species of predatory vine found in the Realms.[1][2][3][4]


These tough, wiry plants had[2] smooth trunks that varied in brown to yellowish tones[4] and on average grew to heights of 10 feet (3 meters).[3] They had vines that were light green in color,[3] yet looked desiccated, and were covered in leaves as well as[2] sharp, hollow thorns.[1][2][3][4] Their leaves were pointed, had two-lobes,[4] and were pale in color. But once a bloodthorn fed, their leaves took on the same color as a victim's blood.[1]

On average their vines grew to lengths of 7​ to ​12 feet (2.1​ to ​3.7 meters),[4] while their thorns were typically 3 feet (0.91 meters) in length. Bright red berries also grew continually on these plants. They were juicy, yet bitter, and produced a fragrant odor that appealed to most creatures[2]


These plants were capable of a limited degree of movement.[1][3] In addition, a few scholars believed that extreme cold could immobilize these plants and that electricity could cause them to grow.[3]


Whenever a living creature came close to them a bloodthorn would lash out with as many of its tendrils as possible, grappling the creature and jabbing it with its thorns in an effort to extract blood.[1][2][3][4] However, they typically ignored scavengers and allowed them to remove the carcasses of their victims.[2]


Following the Spellplague, the inhabitants of the city of New Sharandar grew bloodthorns on their defensive wall, the Living Abatis.[5]


After a good feeding of three or more human-sized victims, a bloodthorn would reproduce by shooting out seed thorns away from itself. Such thorns typically flew around 10​ to ​20 feet (3​ to ​6.1 meters) away from their parent.[3]


These plants were a sanguivorous species, subsisting entirely on the blood of living creatures.[2][4]


Bloodthorns were generally known to grow in thick, briar-like patches in deserts and plains. They were native to the Outer Planes, but could sometimes be found transplanted on Prime Material plane.[2]

In northwest Faerûn, bloodthorn grew in the heavy woods of Cormanthor, Daggerdale, and Shadowdale. Particularly the Border Forest, Spiderhaunt Wood, and the Vale of Lost Voices.[6] In west Faerûn, bloodthorns grew in the Forest of Tethir and the Forest of Mir.[7] And beyond Faerûn, they grew in the jungles of Chult.[8]

Beyond the Prime Material, bloodthorns grew in the barren wastelands of the Abyss, Carceri, Outlands, Pandemonium,[2] and Baator.[9] In the Abyss, they were particularly known to be found on the 1st[10] and the 248th layer.[11] They also grew in the fiendish plane of Fury's Heart.[12]


Dryads and vine horrors were known to sometimes cultivate this plant to use as a guardian. And stirges were known to lair near them in hopes of preying on their ensnared victims.[1]

On the plane of Baator, bloodthorns were often consumed by grazing herds of stench kine.[9]


Alchemists and wizards could often find uses for the hollow thorns of these plants.[3]


Bloodthorns could be summoned by means of the spell summon nature's ally IV.[2]



  1. In Monstrous Compendium Annual Volume Two these creatures are labeled as being carnivores. However, this contradicts their description as blood suckers.
