To dispel a spell, you must make a 'Dispel' roll. To make a Dispel roll, roll 2D6. This represents either the efforts of a Wizard to counter enemy magic, or the twists of fate that can see the Winds of Magic suddenly dissipate.
If you are attempting a Wizardly dispel, add the Wizard's Level to the result of this roll to give a 'dispel result'. If you are attempting a Fated dispel, nothing is added – the result of the Dispel roll is itself the dispel result:
If the dispel result exceeds the casting result, the spell is successfully dispelled and immediately ends.
If the dispel result is equal to or less than the casting result, the dispel attempt has failed. The spell is not dispelled.
