ACTIONS

• Amorphous Body A shoggoth can move through a space as small as 1 foot across without squeezing.

ACTIONS

• Multiattack. The shoggoth makes three pseudopod or crushing suction attacks in any combination.
• Pseudopod. Melee Weapon Attack: +15 to hit, reach 15 ft., one target. Hit: 3d8+9 bludgeoning damage, the target is grappled (escape DC 23). A target grappled by the shoggoth’s pseudopod is restrained.
• Engulf. The shoggoth moves up to its speed, and can enter other creatures’ spaces if they are Huge or smaller. Each creature whose space the shoggoth moves into must make a Dex save (DC 18); a creature grappled by the shoggoth automatically fails. On a success, the creature is pushed as far as the shoggoth moves, or out of its path to the side. On a failure, the shoggoth engulfs the creature and can keep moving. An engulfed creature can’t breathe. It is restrained and moves with the shoggoth. An engulfed creature can escape by using an action to make a Str check (DC 23), moving to a space adjacent to the shoggoth if it succeeds.
• Crushing Suction. A creature engulfed by the shoggoth takes 6d8+9 bludgeoning damage, or half damage if it makes a Con save (DC 23).

ABOUT

A massive, iridescent heap of black protoplasm, this obscene creature forms eyes, pseudopods, and bubble-like extrusions as it pulses and moves. It mimics sounds nearby in a thin, piping myriad of voices.

Long ago shoggoths were bred from the earliest protoplasm of earthly life to serve as the mindless slaves of a mysterious ancient race. In time they gained a degree of malign intelligence and rose against their masters, destroying their civilization and laying their vast stone cities to waste. Shoggoths linger still in the crumbling ruins of their long-dead creators; they eagerly pursue and devour any organic creature unlucky or foolish enough to venture within their grasp.

Shoggoths are naturally formless and plastic, easily able to shape their bodies to a variety of purposes. They are horrifically strong, and can crush or pull apart the toughest prey with ease-in fact, they are notorious for pulling the heads off their victims.
