Barghest

A mix between spirit and demon. They act in many different ways be it, as familiars to witches and warlocks, typically helping them gather their more… human centric materials, guides to prevent harm to travelers, dark omens, or as a wild animal, killing those who cross into its territory at night. They are incorporeal, meaning most weapons do nothing to them and simply phase through them. The best way to kill a harmful Barghest is to bring them into a bright light, produced either by a strong fire or a wide beam LED flashlight. They possess unnatural speed, strength, night vision and can detect nearby light. Barghest are also now as black dogs.
