If a spell is cast, the opposing player can make one attempt to dispel it. The player takes as many dispel dice as he wishes from the army's dispel pool, rolls them and adds their results, obtaining a dispel result. He then compares the dispel result with the casting result rolled by the caster's power dice.

If the dispel result is equal to or higher than the caster's score, the spell is dispelled - it is not cast and has no effect.

If the dispel result is lower than the caster's casting result, the spell is said to have been cast successfully. Measure the range to the target and resolve the effects of the spell if in range.

For example, if the caster used four dice and got a result of 20, the dispelling player must score 20 or more on his dispel dice to dispel the spell.

Note that even an army that does not include any Wizards can still attempt to dispel an enemy spell. representing its natural magical resistance.

As dispel dice are rolled, they are expended just like power dice, reducing the player's ability to dispel further spells.

Some magic items may allow a Wizard a second dispel attempt, or a re-roll, but these are exceptions and in normal circumstances only one attempt can be made to dispel a spell. In addition, the result can be increased further by the use of magic items. Any number of magic items can be combined to boost the score, but the player must declare that he is using any magic items before he makes the dispel dice roll. It is not permitted to roll the dice and then decide to use a magic item retrospectively. Many of these magic items can only be used a limited number of times, so it is important to be clear about whether you are using them or not, before rolling the dice.
