The spellbook of finger, in Slash'EM Extended and SlashTHEM, teaches the finger spell. This level 2 divination spell, not to be confused with finger of death, has the same effect as a wand of probing, revealing a target monster's status and inventory, as well as buried items and the contents of statues and containers. There are a few significant differences, however:

  • "Finger" will not reveal the identity of invisible creatures.
  • Casting "finger" on peaceful creatures may anger them (tame creatures are safe).
  • The spell may wake up creatures that are asleep.

Despite these shortcomings, the spell can be a reasonable substitute for the wand of probing or stethoscope, whenever checking up on your pets or examining non-sleeping hostile monsters from a distance. Unlike the wand of probing, it can be used indefinitely, as long as you have no restrictions on spellcasting and have sufficient energy. The stethoscope can also be used indefinitely, but does not reveal inventory, can only be used on adjacent monsters, and, in Slash'EM Extended, has a 1% chance of breaking whenever it is used.

This spell comes originally from NetHack: The Next Generation.
