A Talisman is:

• A Foci of a Church Orderly, used to store (and cast) the magic of the Order's spells (each spell is a separate skill that can be raised with Hero Points). All of the spells of a specific Order are recording in the Order's Formulary.
• A Foci of a Wizardry Adept, or Apprentice used to record and (repeatedly) cast a specific spell from one of the Grimoires the Adept is familiar with. Each Adept as a seperate skill in each of the Talisman's spells he knows.
