Werewolf

Light the candle and let it burn for a while. When there's enough melted wax in the bottom to drown the charm in, drown the charm in the wax and say:

"By this seal,
I do reveal,
By fur,
By fangs,
By the hunter's blade
I shall shift,
I shall twist,
Under a moon no less than Full;
A wolf of all,
Running free and running wild;
A wolf! A wolf!
Ears, long fur and clawed feet,
By this wax,
Oh how it's binding,
Trap the spirit of the moon in it's coating
For if I might and if I may,
A werewolf shall I be today.
For I cannot bear to be human any longer,
On my will and On the full moon's light;
I shall be bonded to the night."

Then wear the charm to bed and when you wake up take it off only to shower/bathe. Wear it until the next night, and then take it off. Don't look at it until the night of the next full moon, and wear it once again whilst under the moon. You should shift within an hour.
