A
NetHack potion of minor utility. Any
nymph has a good chance of carrying one, and they will sometimes try to
steal them from you. This
potion is really only useful if
blessed, in which case you will know the appearance and location of all objects on the level and in your
inventory. This is primarily useful if you are
blind, or if you are starving and looking for
food.
The uncursed potion just finds all objects on the level. The cursed version does the same thing, but mimics will appear as objects.
Throwing the potion at a monster or inhaling the vapors has no effect whatsoever.
