Enlightenment

From Wikihack

Enlightenment is a brief, one-time-only indication of a number of normally hidden character attributes, such as Luck, alignment record, and resistances to elemental attacks such as fire. When you get an enlightenment, "you feel self-knowledgeable" and these attributes are displayed; when you dismiss the window, "the feeling subsides" and the list cannot be displayed a second time.

Enlightenment can be triggered in these ways:

• quaffing a potion of enlightenment
• zapping a wand of enlightenment
• invoking The Eyes of the Overworld
• drinking from a fountain (one in 30 chance)
• in wizard or explore mode, pressing control-X
• answering yes to "Do you want to see your attributes?" when the game ends; in this case, the messages are in the past tense
