Mask Magic

When cast, this odd spell goes into suspended animation, awaiting the trigger that will set it off. That trigger is anyone attempting to detect magic whether magically or psionically. When someone does so, mask magic covers up whatever magic the caster has in use (including itself) with a false veneer of psionic strength (PSPs) being expended. In effect, it creates a belief within the person detecting magic that he finds none. If that person can also detect psionics in use, the spell provides them with the false information that psionic energy is being used.

The spell lasts for 5 rounds after first being set in motion, regardless of how many people test the area for magic. If not used within 12 hours of being cast, the spell fades away. This is a favorite of arena mages and other wizards who must practice their craft openly. The material component for the spell is a tiny piece of mirror or a shiny, reflective rock.
