Shredskin

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

Constrict — 1d4+4 bludgeoning damage, DC 16 Fortitude Constrict

Control Body — 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 Off-Guard 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 a Perception check against the shredskin's Deception DC.

Enshroud — On a success, the creature becomes Restrained and the shredskin can take control of the creature as if using Control Body. At the start of its turn, the shredskin can automatically Constrict the enshrouded creature as a free action. An enshrouded creature can attempt a check to break free ( if the shredskin critically succeeded its Athletics check to Enshroud).
