To make yourself invisible, mix together three drops of blood from the index finger of your left hand, three drops from the ring finger of your right hand, two drops from your right nipple and two from your left one. Then mix it together with the blood from the heart of a living raven and boil it with the raven´s brain and a man´s bellyfat. Then use the ink to carve this sign on a piece of lignite and keep it in your hand.
