|Notes||Wrigglers resemble maggots, with a hard shell encasing the head. If any part of the body is separated from the rest, pieces grow a new body and head. If the head is destroyed, the creature dies. They burrow into living flesh using a rigid proboscis, which releases a mild anaesthetic oil, preventing most potential hosts from notic- ing the attack (Stealth check). If one point of damage is done, they enter the body to first burrow inward and then toward a kidney to nest at a rate of one hit location per day, inflicting a damage of one per location. They can be cut out of limbs with a successful Medicine check and simple tools. In the head, torso, or abdomen, complicated surgery is required to remove them. Their preferred entry point is the eye, but any location will do.
