According to an old recipe found at the Musee de la Sorcellerie in Blancafort, France, a lucky bracelet to improve your fortune at games of chance can be made as follows:
An eel that died for lack of water
Gall of a bull killed by fierce dogs
A hanged man's rope
A fern picked on Midsummer's Eve
A raven feather
Your own blood.
Put the gall into the eel skin with a drachme of vulture blood.
Tie the eel skin with hanged man's rope and leave in warm dung for 15 days.
Dry in an oven heated with fern, then make a bracelet of it, writing the letters HYTV on it in your own blood using a raven's feather.
With this bracelet on your arm, fortune will always smile on you.
