Black Cat Oil is empowered by the infamous Black Cat Bone: the magic bone of European Origin, that has spread all over the world. A gruesome rite, codified by grimoires: to procure a lucky black cat bone, the magician should boil a black cat alive at midnight, sloughing its flesh from the bone, and placing each bone in the cheek while sitting in front of a mirror. The bone that caused the vision to go dark would be the lucky bone, which would give one the power to become invisible, gain mastery over animals, or become very lucky in gambling. The oil, containing a Magic Black Cat Bone, is used to anoint to charms for gambling. It can be anointed to Black Cat Figure Candles to bring luck, or can be used to go unseen. Anointed to the door of a business, it can help draw clients.
