Shulgurk

Shulgurk can speak with spiders, with the same effects and limitations as speak with animals.

Shulgurk has imprecise tremorsense to detect the vibrations of creatures touching any webbing in areas A12–A15.

Shulgurk attempts to embed a toothy sphincter at the end of a leather hose attached to his infernal machine in the flesh of a living creature that's also within 10 feet of the infernal machine. The torturer makes an infernal machine hose Strike against the Restrained creature, with a hit successfully attaching the hose to the creature, that's thereafter Off-Guard and susceptible to Exsanguinate Subject until the hose is detached.

Safely removing an attached sanguine hose from a living subject requires spending an action to attempt a DC 16 Crafting or DC 16 Medicine check, or a DC 20 Athletics check (these DCs increase by 4 (DC 20 Crafting, DC 20 Medicine, DC 24 Athletics) if the Strike to attach the hose was a critical hit), with the following results.

Critical Success The hose detaches without additional damage to the subject.

Success The hose detaches from the subject fairly cleanly, but the toothy sphincter at its end manages to take a chunk of flesh as a souvenir, dealing 1d4 piercing damage to the subject.

Failure The hose separates from the skin with a sickening "plop" and a spurt of fresh blood. The subject takes 1d4 piercing plus 1d6 persistent bleed damage

Critical Failure As failure, but the subject also becomes Drained 1.

Shulgurk changes into his hybrid form, spider form, or human form. The above statistics assume he's in his hybrid form. While in human form, he can't use his fangs attack and loses his climb speed. While in spider form, he can't use weapons.

The monster changes its shape indefinitely. It can use this action again to return to its natural shape or adopt a new shape. Unless otherwise noted, a monster cannot use Change Shape to appear as a specific individual. Using Change Shape counts as creating a disguise for the Impersonate use of Deception. The monster's transformation automatically defeats Perception DCs to determine whether the creature is a member of the ancestry or creature type into which it transformed, and it gains a +4 status bonus to its Deception DC to prevent others from seeing through its disguise. Change Shape abilities specify what shapes the monster can adopt. The monster doesn't gain any special abilities of the new shape, only its physical form. For example, in each shape, it replaces its normal Speeds and Strikes, and might potentially change its senses or size. Any changes are listed in its stat block.

By spending several minutes, Shulgurk can produce silk to craft items made of webbing or cloth. He can produce enough silk in a day to craft a single garment.
