  • Devourer’s Starvation. The gluttongeist always knows the distance to and direction of the nearest creature or whatever else it might perceive as food. On each of its turns, it uses all its movement as necessary to move toward the nearest perceived food source.
  • Ethereal Sight. The gluttongeist can see 60 feet into the Ethereal Plane when it is on the Material Plane, and vice versa.
  • Incorporeal Slime. The gluttongeist can move through other creatures and objects as if they were difficult terrain. If it moves through a creature or object, it covers it in an ectoplasmic slime, and if it is a creature, it must roll a DC 15 constitution saving throw. On a failed saving throw, the creature is frightened until the end of its next turn, it cannot regain hit points, and its speed is reduced by 10 feet. On a success, the creature’s speed is reduced by 10 feet but it suffers no other effects. If the gluttongeist ends this move inside an object, it takes 5 (1d10) force damage and is shunted to the nearest unoccupied space.
  • Limited Telepathy. The gluttongeist can magically transmit simple messages and images to any creature within 120 feet of it that can understand a language. This form of telepathy doesn’t allow the receiving creature to telepathically respond.
  • Rampage. When the gluttongeist reduces a creature to 0 hit points with a melee attack on its turn, the gluttongeist can take a bonus action to move up to half its speed and make a Bite attack.
  • Undying Hunger. The gluttongeist does not regain Hit Dice normally. Instead, each night at sunset, it loses one Hit Die. If it reaches 6 or fewer Hit Dice, its painful hunger gives it disadvantage on Constitution and Wisdom saving throws. When the gluttongeist is reduced to 0 Hit Dice, it is permanently destroyed.


  • Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 17 (2d12 + 4) necrotic damage, and the gluttongeist magically regains hit points equal to the damage dealt. The target is also swallowed if it fulfills one of the following conditions:

    • Target is a Small or smaller object not being worn or carried
    • Target is a Small or smaller creature
    • Target is a Medium creature and the attack reduces it to less than half its hit point maximum

    A swallowed creature is blinded and restrained, has total cover against attacks and other effects outside the gluttongeist’s gullet, and takes 7 (2d6) necrotic damage at the start of each of the gluttongeist’s turns.

    The gluttongeist’s gullet can only hold one creature at a time. If the gluttongeist dies or takes 10 damage or more on a single turn from a creature inside it, any swallowed creatures or objects fall out of of the gluttongeist’s ghostly form, landing prone in the nearest unoccupied space and ending all effects of being swallowed.

    However, such a creature is covered in ectoplasmic slime, reducing its speed by 20 feet until it is cleaned off. Cleaning the slime off by hand takes 1 minute.

    Whenever the gluttongeist swallows a creature or swallows at least 5 cubic feet of other organic matier, it regains 1d4 Hit Dice if the creature or organic matier is still swallowed 1 minute later.


  • Eager Appetite. When a creature within 5 feet of the gluttongeist hits it with an attack roll or forces it to make a saving throw, the gluttongeist can make a Bite attack against that creature.


A gluttongeist is a ravenous, all-consuming spirit whose endless hunger drives it to devour every living thing it encounters. Created from greed and glutiony, it is not uncommon for the spirits of giants and ogres to become these dreadful specters after living lives of exceptional greed and glutiony. In instances where Humanoids become a gluttongeist, little to nothing remains of the original form of the deceased Humanoid.

Gluttongeists possess limited telepathic abilities, however the messages they send to others tend to be unintelligible ramblings of hunger. Unfortunately, telepathic communication remains the only way of learning the identity of the glutionous specter and learning where it came from.
