Constrict (Ex)

As a swift action, a shambling mound can transfer a target grappled by its slam into its coils and crush their body. This deals 1d8+11B damage to the grabbed target, who must also make a DC 14 Fortitude save or lose 1d4 rounds of holding their breath to avoid suffocating.

Electrical Fortitude (Ex)

Whenever the shambling mound is subjected to electrical damage, it takes no damage and regains a number of hit points equal to the lightning damage. Every 5 points of electrical damage that would be dealt to the shambling mound, provides 1 round of haste (as the spell) for the shambling mound.

Mound (Ex)

When it’s not in danger, the shambling mound spends 1 minute settling into a pile that looks like a lump of loose vegetation. While it is in this form, creatures must actively search and succeed at a DC 24 Perception check (DC 29 in forests or swamps) to detect the shambling mound’s true nature.


Environment forest or marshes
Organization solitary

Shambling mounds are a type of plant creature that dwell in forests and swamps. They appear to be moving, vaguely man-shaped mounds of rotting vegetation, standing 9 feet tall and weighing about 3,500 pounds (350 bulk). Shambling mounds feed off of the decaying flesh and blood of living creatures they have engulfed and crushed within their own bodies.
