Suspend Magic

Area; Resisted by subject spells 
Temporarily nullify all other spells within the area. It has no effect on enchanted items. Certain powerful spells are also unaffected – specifically, those which can only be removed by Remove Curse. Each spell resists separately. 
Suspend Magic is not selective; the caster can choose the shape of the area within the boundaries he pays energy for (as with all Area spells), but may not exclude objects within the affected area. The caster need not know the spell(s) being suspended. To suspend a specific spell without affecting others, use Suspend Spell.
