Strategy

The spell of detect unseen can be 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. However, for most NetHack players a wand of secret door detection will not be hard to find, and each one carries many charges. Some foodless atheist players cast this spell to detect traps they cannot acquire resistances to.
