Black Tentacle. The corpse worm manifests a single black tentacle next to itself, near a foe, out of a nearby corpse, or out of a pool of blood. (With a range of 90 feet.) When a creature enters the affected square for the first time on a turn or starts its turn there, the creature must succeed on a Dexterity saving throw or take 1 bludgeoning damage and be restrained by the tentacle for 1 turn. As soon as the spell-like ability has affected someone once it ends.
A necrotic magical insect that feeds off corpses and has a preference for the freshly slain. These creatures normally reside within planes of existence where rivers of blood are common, using such as their primary home when corpses aren’t available. In the wilds of other planes, swarms of corpse worms congregate in the bodies of massive creatures, and when the corpse is running out of room they begin to seek out new bodies to latch unto in their search for a sustainable food source. On their lonesome however they are utilized by alchemists and necromancers alike in their pursuit of understanding the ways of death.
The corpse worm appears superficially similar to an eel but with an elongated beak-like face that splits into four jaws. Closer inspection, however, reveals the insides of their jaws feature rows upon rows of prehensile teeth and that each segment of their face bares three waxy eyes similar at first glance to those of a human but invariably thicker. When exposed to blood the iris in the eyes of a corpse worm twist into an X-like structure somehow enabling them to see through blood as if clear air.
The hide of a corpse worm may come in many varied colors depending on its exact breed, purpose, or place of origin, however, most are either a pale blue-green with a darkened face or a burnt looking reddened-black. Many breeds feature specific additional features such as slashes of white along their back or even blood red bellies with pale spots down the sides.
