Gelatinous Mass

A gelatinous mass is a transparent ooze composed of mindless, gelatinous matter in the shape of a cube or polyhedron typically conforming to the shape of the most common pathways. These creatures were created to act as a sanitation purpose to devour refuse and clean designated areas; however, the experiment did not work as hoped and now these oozes exist in hundreds of underground locations.
Typically, a gelatinous mass measures between 10? to ?15? feet on a side and might weigh as much as 50,000 ?pounds. The creature is completely transparent, with only a glint of its surface in the light to give away its position. The occasional random object floating in a well fed gelatinous mass’ body could also serve as a warning of its presence to dungeon delvers. It requires a Perception check (DC:17) to spot one at the range of whatever light source or sight there is. gelatinous mass’ bodies were remarkably moldable. They could flow around objects and through narrow passages, quickly returning to their shapes once enough space was available. These monsters are immune to blunt damage. They are also resistant to edge and piercing damage even from magical weapons.
Additionally, the mass takes up its entire space. Other creatures can enter the space, but a creature that does so is subjected to the mass’ engulf-attack and has disadvantage on the save against it. Creatures inside the mass can be seen but are at full cover. A creature within 5 feet of the mass can take an action to pull a creature or object out of the mass. Doing so requires a successful feat of Strength (DC:16). However, the creature making the attempt automatically suffers 2d4 points of acid damage. A mass can hold only one large creature or up to four medium or smaller creatures inside it at a time.
The gelatinous mass may strike out up to 5 ft reach with a pseudopod attack against a single creature. In addition to the blunt damage from this attack, if successfully striking then 2 additional points of alchemical damage will be delivered. However, the most frightening attack is its engulfing attack. The mass moves up to its full movement speed. While doing so, it can enter large or smaller creatures’ spaces. Whenever the mass enters a creature’s space, the creature must make an Agility check (DC:12). If successful, the creature can choose to be pushed 5 feet back or to the side of the mass. A creature that chooses not to be pushed suffers the consequences of a failed check. On a failed feat, the mass enters the creature’s space and the creature takes 2d4 points of acid damage but is also engulfed. The engulfed creature can’t breathe, is restrained, and suffers 3d4 points of acid damage at the start of each of the mass’ turns. When the mass moves, the engulfed creature moves with it. An engulfed creature can try to escape by taking an action to make feat of Strength (DC:20). On a success, the creature escapes and enters a space of its choice within 5 feet of the mass.
