Chimera, Sludge

Humanoid Form. The chimera can transform to its Ooze Form or Humanoid Form as a bonus action.

Ooze Form. When in its Ooze Form, the chimera's size becomes Large and takes up its entire space. Other creatures can enter the space, but a creature that does so is subjected to the chimera's Engulf and has disadvantage on the saving throw.

Creatures inside the chimeras space can be seen but have total cover.

A creature within 5 feet of the orc can take an action to pull a creature or object out of the chimera. Doing so requires a successful DC 15 Strength check, and the creature making the attempt takes 15 acid damage.

The chimera can hold only one Large creature or up to four Medium or smaller creatures inside it at a time.

Amorphous. The chimera can move through a space as narrow as 1 inch wide without squeezing.

Multiattack. The chimera makes two pseudopod attacks.

Pseudopod. Melee Weapon Attack: +6 to hit, reach 10 ft., one creature. Hit: 14 (4d6 + 3) acid damage.

Engulf. The chimera moves up to its speed. While doing so, it can enter Large or smaller creatures' spaces. Whenever the chimera enters a creature's space, the creature must make a DC 15 Dexterity saving throw.

On a successful save, the creature can choose to be pushed 5 feet back or to the side of the chimera. A creature that chooses not to be pushed suffers the consequences of a failed saving throw.

On a failed save, the chimera enters the creature's space, and the creature takes 15 acid damage and is engulfed. The engulfed creature can't breathe, is restrained, and takes 28 (8d6) acid damage at the start of each of the chimera's turns. When the chimera moves, the engulfed creature moves with it.

An engulfed creature can try to escape by taking an action to make a DC 15 Strength check. On a success, the creature escapes and enters a space of its choice within 5 feet of the chimera.
