A wand of secret door detection detects all undiscovered secret doors, mimics, and traps in a radius of 8 squares upon zapping/engraving. It will also show the location of submerged creatures in pools. Engraving with the wand only identifies it if these things are present; otherwise it gives no message. The wand of secret door detection is most often used for finding the hidden entrance to the temple in Moloch's Sanctum. It can also be used to find the portals on the Elemental Planes.
