Special Traits

  • All Around Vision. A bonesucker can see in all directions at once and cannot be surprised.
  • Magic Weapons. The bonesucker’s weapon attacks are magical.


  • Multiattack. The bonesucker makes four melee attacks.
  • Tentacles. Melee Weapon Attack: +6 to hit, reach 10 ft., one target. Hit: 14 (4d4 + 4) bludgeoning damage. The target is grappled (escape DC 14) if the bonesucker isn’t already grappling a creature, and the target is restrained until the grapple ends.
  • Liquefy Bones. If the bonesucker is grappling a creature at the start of its turn, it can feed on the creature. The grappled creature’s Strength score is reduced by 1d4. The target dies if this reduces its Strength score to zero. Otherwise, the reduction lasts until the target finishes a long rest or lesser restoration or better is used on the target.


This bizarre creature resembles a fleshy tree trunk. Atop its main body protrudes a mass of writhing tentacles that constantly ooze and drip a brownish-yellow fluid. Beneath these is a ring of black, unblinking eyes.

A bonesucker is a bizarre creature that stalks the darkness dank caves and remote wastelands. The body is encased in a thick, rubbery sheath of flesh and muscle that makes the bonesucker highly resistant to injury. The bonesucker moves through the use of five thick tentacles at its base.

Bonesuckers consume only the bones of an opponent by grabbing it and piercing its flesh with hollow tentacles. The tentacles inject digestive enzymes into the bones, which break down and are sucked up as a pasty meal for the bonesucker. The process is horrifyingly painful for victims. Experienced adventurers always know they are nearing the hunting grounds of a bonesucker, because the creature leaves the boneless carcasses of its meals lying where it finished them.

Bonesuckers stand about 10 feet tall.

A bonesucker attacks with its tentacles. Initially, the tentacles appear to be only a foot or two in length, but the bonesucker can extend them to a length of approximately 10 feet. It can attack with up to four of its eight tentacles in a single round.

A bonesucker’s natural weapons are treated as magic weapons for the purpose of overcoming resistances and immunities.
