A spellbook of magic mapping allows you to learn the magic mapping spell, which reveals the entire map (although it does not fully reveal the contents of rooms). It is the special spell for archeologists.
Strategy
The spell will reveal all of the level's walls (but not its rooms) and corridors, as well as the exit stair. It is most popular for making it easier to traverse Gehennom's vast mazes. When combined with teleport and teleport control, magic mapping allows you to traverse whole levels in seconds (cast, teleport to exit stair, leave). Although useful on its own, it becomes even more useful when combined with any one of the following spells:
- Detect monsters, which allows you to head directly for, or avoid, certain enemies.
- Detect unseen, which reveals traps on the level, making traversing it even less dangerous.
- Detect treasure and Detect food, which add another layer of detail to your view.
- Teleportation and teleport control, which allows you to zip to the exit stair almost simultaneously, or anywhere else you want to go.
When ascending after acquiring the Amulet, it can be used to pick up map facets that you missed on your first round through.
