Seal of Destruction [THE EMPIRE]

One use only. 
Once activated this seal can drain the knowledge of one spell from the mind of an enemy Wizard
The seal has the same effect as a Dispel scroll. In addition, roll a D6. On a result of 4+ the spell is removed from the caster's mind and he can no longer cast it. Spells cast from a Bound item will only be removed on the result of a 6.
