The Eyes of the Overworld
|( The Eyes of the Overworld|
|Base item||pair of lenses|
|Base price||2500 zm|
While wearing the Eyes, in addition to the usual effects of lenses, you are granted astral vision: the squares around you are illuminated as if lit by a lamp. The Eyes also provide magic resistance when worn; prior to version 3.6.0, the Eyes provided magic resistance when simply carried. Invoking the Eyes provides enlightenment.
Astral vision penetrates walls, doors, solid rock, and any other obstruction. Objects seen through astral vision using the farlook command are described as though you had personally handled the item (a behavior similar to a blessed potion of object detection; for example, viewing a scroll on the floor will tell you its label, not merely "a scroll," and gems discovered embedded in rock will appear with whatever type-name you may have given them.
Blindness from any source is suppressed while you are wearing the Eyes, which is somewhat analogous to Grayswandir's hallucination resistance. Astral vision does not grant its usual "vision" properties while on the Rogue level: monsters, tiles, and items are not revealed through darkness or obstructions, but the Eyes will still prevent and override blindness.

Because Nethack assumes line-of-sight is symmetrical—that is, if you have a clear line of sight to a monster, it can see you too—monsters are capable of using gaze attacks through walls and other obstructions if they are within a three-tile radius while you are wearing the Eyes. This can be lethally tragic when dealing with Medusa, or if a pesky umber hulk on the other side of an unphaseable or undiggable wall repeatedly confuses you. In such cases, it may be necessary to temporarily remove the Eyes, as astral vision becomes a liability instead of a boon.
If you are attempting the Zen conduct, do not wear this item under any circumstances, as it will instantly break the conduct. As it no longer provides a benefit when carried and the invocation effect of enlightenment is easily achieved through other means, it's best to ignore this artifact altogether to avoid the risk of accidentally wearing it.
The Eyes of the Overworld is a 1966 novel in the Dying Earth series by Jack Vance. The anti-hero Cugel, a resourceful but amoral rogue, is tasked by a wizard to obtain the titular artifact from a squalid village whose "aristocracy" wears the Eyes, which allow them to see everything around them as though it were opulent luxury - fittingly, the Eyes are depicted as literal rose-tinted contact lenses.
... and finally there is "the Eyes of the Overworld". This obscure artifact pushes the wearer's view sense into the "overworld" -- another name for a segment of the Astral Plane. Usually, there is nothing to be seen. However, the wearer is also able to look back and see the area around herself, much like looking on a map. Why anyone would want to ...
