|Name||secret door detection|
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.
Identification of this wand is very easy. It is non-directional; you are not asked for a direction in which to zap it. This property is only shared with the wands of light, enlightenment, create monster, and wishing, all of which have very obvious effects when zapped.
Wands comprise 4% of all randomly-generated items in the main dungeon, 6% in containers, 5% on the Rogue level, and 8% in Gehennom. There is a 5% chance that a randomly-generated wand will be a wand of secret door detection.
