The horrible creature walking into view is a mass of free-roaming intestines, flaccid organs, and a few odd rib bones. Dragging behind it like a dead weight is a lolling, maggot-ridden humanoid head.

A skulking cyst is disgorged from the rotting corpse of a living creature, born of a necrotic cyst that eventually kills its host (see the necrotic cyst spell,).

A skulking cyst prefers shadows and dark corners, only revealing the horror of its form when it strikes lone victims from hiding. Though often cloaked in the detritus of a previous victim, the skulking cyst's true "heart" is a 1-foot-diameter spherical sac that contains fluid and semisolid necrotic flesh, which slowly undulates as if in a mockery of breath.

A skulking cyst does not speak, but it understands Common and the languages its fleshy carapace originally spoke in life.
