The scroll of detect magic, from GruntHack, acts as a potion of object detection - though it is restricted to detecting magical items and items with abnormal magic properties - and also detects spellcasting monsters.
An uncursed scroll of detect magic will show you the location of all magical items and items with object properties on the level, and flag any unidentified items revealed in this fashion with a "magical" prefix as though the player was a wizard. A blessed scroll will additionally identify the type of magical item and any object properties. Cursed scrolls also detect mimics mimicing objects, and will wake up any monsters detected (both spellcasters and mimics).
