Description
When cast, the spell generally has the same effect as a potion of object detection, depending on the skill level it is cast at[1] - at Basic skill or lower the spell reveals the location and item type of every object on the level and exercises wisdom. At Skilled or higher, the spell reveals the location and item type of every object on the level, and additionally reveals the appearance of every item on the ground and in your inventory, as if you had seen them yourself.
Strategy
Like the potion of object detection, the spell of detect treasure can be used to prioritize items when exploring, such as finding the Castle chest with the wand of wishing or finding vaults that are not looted yet by revealing the 2x2 square of gold contained within.
Though somewhat difficult to cast for most roles without training in divination spells, once a hero can reliably cast the spell it can become preferable to the potion of object detection: though the potion is commonplace, multiple potions are decently heavy to carry and excess ones are usually diluted into water for other purposes. Conversely, detect treasure can be cast so long as you have the energy available to, though that energy cost may be high depending on armor and failure rates, unless you have plenty energy to spare or else do not plan to expend much of it in combat.
History
The spellbook of detect treasure is introduced with all other spellbooks in NetHack 1.3d.
Messages
