When
quaffed, a
potion of
enlightenment will allow you to see your
attributes in exactly the same manner they are revealed when you
die (except this time, the phrase "You are dead." will be absent). This
potion is especially useful to figure out if you can safely
pray.
A blessed potion of enlightenment also confers 1 point of Intelligence. The cursed version has no effect and abuses your Wisdom ("You have an uneasy feeling"). No effect if thrown or if the vapor is inhaled.
