Amulet of the Archwizard

These light‚ gold medallions on silver chains were worn under the clothes of an archwizard. Each stamped with the coat-of-arms of a particular city (so people thought it was nothing more than a status symbol). The amulet acted as an amulet of proof against detection and location. It allowed the wearer to teleport without error to any area of the city with the utterance of a command word. Individual archwizards placed additional incantations on these amulets to suit their personal tastes and paranoia, such as a removable clasp that could be tossed aside just before the arcanist teleported away that activated like a delayed blast fireball.
