A
bizarre NetHack tool that would be entirely
useless except that you can
apply it once per turn at no
time cost; that is, it doesn't count as your
action for that turn. Applying it more than once per turn will cost you one turn per use. The stethoscope will sometimes
probe adjacent monsters, showing their
hit point totals, etc, and will also find
secret passages. A
cursed stethoscope has a 50% chance of just hearing your own
heartbeat. The whole thing is pretty
sketchy -- I'd keep your
distance from a
NetHack player who regularly uses a stethoscope.
Applying a stethoscope produces some funny messages in certain situations:
Applying to a corpse, when hallucinating:
"You hear a voice say, "It's dead, Jim."
Applying to a statue:
"The grid bug seems to be in excellent health for a statue."
Trying to apply it to an invalid location:
"You hear a faint typing noise."
