The mage curses an item so that it penalizes the use of one or more Arcana.
For every five successes added to the target number of the spell, the mage specifies one Arcanum. Any mage casting a spell from any of the specified Arcana while wearing or carrying the cursed item suffers a dice penalty equal to the Mana spent during its creation.
