Is there such thing as good luck?

Although there are a few spells used to bring good luck it is more common to make and/or carry a talisman or amulet for the purpose.

Amulets are usually items such as jewelery or something already made that have been magically charged to bring a desired effect in this case, good luck. A lucky penny, a rabbits foot or a piece of jade.

A talisman is something constructed, carved, painted etc, using specific symbols on certain materials and magically charged using a "spell." For example a round dick of wood, carved or painted with an Egyptian scarab is very lucky.
