Single use. The bearer of the Silver Mirror may use it when attempting a Wizardly dispel. If they do so, roll an extra D6 when making the Dispel roll and discard the lowest result. If a double 1 is rolled on any two of the dice rolled, the bearer is outclassed in the art and the dispel attempt fails. If the dispel attempt is successful, the spell is dispelled and the casting Wizard suffers a Strength 4 hit with an AP of -2.
