Compression When a shredskin successfully Squeezes, it moves through the tight space at full speed. Narrow confines are not difficult terrain for a shredskin.

Control Body [>] Requirements The shredskin is in the same space as a Medium or Small humanoid-shaped corpse; Effect The shredskin wraps itself around the corpse as a new skin and takes control of the host body. While controlling a host, the shredskin uses the host's Speed but its own attacks, and it loses its Grab and Enshroud abilities. Attacks that target the shredskin while it controls a body deal half of the damage to the shredskin and half of the damage to the host body. Attacks that target an area deal damage to both the shredskin and host body normally. The shredskin can release the host body as a free action at the start of its turn. If the host is destroyed, the shredskin automatically releases the body and is flat-footed for 1 round. A Medium corpse typically has 15 Hit Points, while a Small corpse typically has 10 Hit Points. Creatures can notice that a corpse is controlled by a shredskin by succeeding at a Perception check against the shredskin's Deception DC (typically 18).

Enshroud [>] (attack, incapacitation) Requirements The shredskin is restraining a creature; Effect The shredskin wraps itself around the restrained creature like a shirt, seizing control. The shredskin rolls an Athletics check against the creature's Fortitude DC. On a success, the creature becomes restrained until it Escapes and the shredskin can control the creature as described in Control Body. At the start of each of its turns, the shredskin can attempt to Constrict the enshrouded creature as a free action. An enshrouded creature can attempt a DC 16 Escape check to break free (DC 18 if the shredskin critically succeeded its Athletics check to Enshroud).
