Special Traits

• Amorphous. Gluttony can move through a space as narrow as 1 inch wide without squeezing.
• Legendary Resistance (3/day). If Gluttony fails a saving throw, it can choose to succeed instead.
• Magic Resistance. Gluttony has advantage on saving throws against spells and other magical effects.
• Magical Weapons. Gluttony’s weapon attacks are magical.

Actions

• Multiattack. Gluttony makes two bite attacks or one spit attack.
• Bite. Melee Weapon Attack: +13 to hit, reach 10 ft., one target. Hit: 37 (7d8 + 6) piercing damage.
• Spit Slime. Ranged Weapon Attack: +13 to hit, range 30/80 ft., one target. Hit: 15 (2d8 + 6) bludgeoning damage plus 36 (8d8) acid damage.
• Create Cubes (1/day). If there is space to do so, the demon can create 1d4 gelatinous cubes out of its body. The new oozes will obey the demon’s commands and are destroyed if it dies.
• Engulf. The demon moves up to its speed. While doing so, it can enter Large or smaller creatures’ spaces. Whenever the cube enters a creature’s space, the creature must make a DC 17 Dexterity saving throw. On a successful save, the creature can choose to be pushed 10 feet back or the side of the demon. A creature that chooses not to be pushed suffers the consequences of a failed saving throw. On a failed save, the demon enters the creature’s space, and the creature takes 21 (6d6) acid damage and is engulfed. The engulfed creature can’t breathe, is restrained, and takes 35 (10d6) acid damage at the start of each of the demon’s turns. When the demon moves, the engulfed creature moves with it. An engulfed creature can try to escape by taking an action to make a DC 17 Strength check. On a success, the creature escapes and enters a space of its choice within 5 feet of the demon.

About

Under the cover of night, a massive ooze slides inside a manor and engulfs the occupants. When the elite guards enter the building in the morning, is has been scrubbed clean. None of the inhabitants survived the night. Gluttony is an enormous demon that devours as much as it can.

Beast Feast. This hideous creature will feast on food, livestock, and even humanoids. It continuously consumes organic matter as it moves through the world. Although it’s not that intelligent, the demon is rather wise.

Fiendish Friends. Unbelievably, some evil nobles will invite Gluttony to their banquets. They make a bargain with the demon, feeding it in return for favors. If anyone complains about the presence of the hideous monster, they will be escorted out of the feast or added to the menu.

Urban Sprawl. Gluttony can lay waste to entire urban settlements. Buildings and other structures remain in place, but it consumes all living creatures.
