The scroll of amnesia is the only indisputably bad scroll (even the scroll of punishment gives you a heavy ball to use as a weapon). Reading one makes you forget things and abuses your wisdom.

Reading effects

You have a 1/3 chance of forgetting up to 25% of all known level maps and a separate 1/3 chance of forgetting up to 25% of object identities. You forget all traps on your current level (except any in which you are stuck), forget whether you are punished, and abuse your wisdom. If this causes you to forget the identity of scrolls of amnesia themselves, they are re-identified.

Additionally, the BUC status of the scroll and whether or not you are confused imposes extra effects:

Case	Effect
cursed or not confused	You forget all of the current level.
non-cursed and confused	You forget 6/7 of the current level.
non-blessed	You forget any number of spells.

N.B.: Sokoban maps are not forgotten.

Messages

Message	Reason
"Who was that Maud person anyway?"	You read a scroll of amnesia
"Thinking of Maud you forget everything else."
"As your mind turns inward on itself, you forget everything else."	You, a character named Maud, read a scroll of amnesia
"Your mind releases itself from mundane concerns."	You read a scroll of amnesia while hallucinating

Identification

Reading the scroll identifies it with devastating consequences, so you are well-advised to ID this and all other 200zm scrolls by elimination or by a scroll or spell of identification.

Monsters will not read this scroll.

Strategy

Scrolls of amnesia are a perfect candidate for blanking.

Encyclopedia entry for amnesia

                    Get thee hence, nor come again,
                    Mix not memory with doubt,
                    Pass, thou deathlike type of pain,
                    Pass and cease to move about!
                    'Tis the blot upon the brain
                    That will show itself without.
                            ...
                    For, Maud, so tender and true,
                    As long as my life endures
                    I feel I shall owe you a debt,
                    That I never can hope to pay;
                    And if ever I should forget
                    That I owe this debt to you
                    And for your sweet sake to yours;
                    O then, what then shall I say? -
                    If ever I should forget,
                    May God make me more wretched
                    Than ever I have been yet!
                            [ Maud, And Other Poems by Alfred, Lord Tennyson ]
