General: quaffing the potion can remove
intrinsics or bad conditions such as hallucination. (The potion is
badly misnamed, as is traditional in Nethack.)
Lose-able intrinsics: lycanthropy, confusion,
stun, hallucination, blindness, aggravate monsters, teleportation, telepathy,
fire resistance, cold resistance, poison resistance, invisibility, see
invisible, fast, stealth, protection.
Regardless of b/u/c status:
If you are wearing a ring of sustain ability, or
if you have no lose-able intrinsics, nothing happens:
"You feel like chuckling."
Blessed
You get the option of losing each lose-able intrinsic.
The potion is IDed.
You exercise your wisdom.
Uncursed
You lose a random lose-able instrinsic. Good
luck gives a slight tendency to remove bad conditions. Bad luck tends
to remove the better intrinsics.
You abuse your wisdom.
Cursed
You lose a random lose-able instrinsic, as above,
then all other lose-able intrinsics are checked. For luck of zero
or greater, each has a (20% - luck) chance of being lost. For negative
luck, each has a (20% - 3*luck) chance of being lost, which hits 59% for
-13 luck.
You abuse your wisdom.
Hits monster
The monster is cancelled.
Vapors
"You feel like chuckling." (not
hallucinating)
"You hear someone not chuckle."
(hallucinating)
Dipping effects
Dipping something into lose ability
cancels the item and uses up the potion.
