The Phiomia is a passive, early-game creature that flees when threatened, so immobilize it with a bola or trap it against terrain before knocking it out. Tame it with berries while protecting it from predators, as it eats quickly during the process. Once tamed, it offers useful carrying capacity and mobility for transporting supplies, while force-feeding Stimberries produces abundant feces for composting or feeding Dung Beetles.
