Strategy

Archaeologists' high intelligence let them make good use of the Orb of Detection for portal detection. The invoke effect is not useful, since sources of invisibility are common.
If you are carrying it for its magic resistance, it is recommended to find a source of worn magic resistance before challenging the Wizard of Yendor, since he can steal it.
As a lawful artifact wish, the Orb of Detection has a more useful base type than the Magic Mirror of Merlin and provides half spell damage. However, it is much heavier.
