This spell is a more potent version of Red Ward and Black Ward. When cast it suppresses the flows of both Red and Black magic in a specified area. All Mages in that area find that their Magic Saves are decreased by 10 for the duration of this spell. The only Mage immune to this effect is the Casting Mage. The area of effect is normally 3 times the Mage’s Level in strides and the duration a number of combat turns equal to the Casting Mage’s Level.
