May be cast on an enemy unit within 24" of the caster and may be cast into close combat. If successfully cast, the owner of the unit must reveal to the caster all the magic items in the unit. The caster then chooses one of them to be nullified for the rest of the battle. The spell itself does not remain in play, but the effect lasts for the remainder of the battle.

Vaul's Unmaking can drain the magic from Dwarf rune items. Note that all the runes on an individual item will be drained by the spell, not just one.

If the unit has no magic items then the spell has no effect.
