A '''scroll of amnesia''' is a type of [[scroll]] that appears in ''[[NetHack]]''.

==Description==
Reading a scroll of amnesia subjects the character to [[amnesia]] and causes them to forget several pieces of knowledge, with the exact effects dependent on the scroll's [[beatitude]] and whether or not they were [[confused]].{{refsrc|src/read.c|896|nethack=3.6.7|comment=<code>forget(howmuch)</code>}} This [[abuse]]s [[wisdom]] and will [[auto-identify]] the scroll after knowledge loss is applied.{{refsrc|src/read.c|1583|nethack=3.6.7}}

===Level maps===
The character forgets the map of the current level along with any related [[annotation]]s and [[overview]] information, including knowledge of their [[punishment]] status, as well as known [[trap]]s on the level except [[hole]]s (which become visible once in the character's line of sight) and any trap the character is currently stuck in.{{refsrc|src/read.c|796|nethack=3.6.7|comment=<code>forgetmap(howmuch)</code>}}{{refsrc|src/read.c|815|nethack=3.6.7|comment=forget overview and annotation data}}{{refsrc|src/read.c|899|nethack=3.6.7}}{{refsrc|src/read.c|902|nethack=3.6.7|comment=call to <code>forget_map(howmuch)</code> from <code>forget(howmuch)</code>}}{{refsrc|src/read.c|1585|nethack=3.6.7|name="allmap"|comment=<code>ALL_MAP</code> set only if not confused}}{{refsrc|src/read.c|902|nethack=3.6.7|comment=<code>forget_traps()</code>}} If the scroll is non-cursed and was read while confused, the character forgets only {{frac|6|7}} of the current map.{{refsrc|src/read.c|807|nethack=3.6.7|comment=<code>forget(howmuch)</code>}}<ref name="allmap"/>

The character also has a {{frac|3}} chance (33%) of forgetting known level maps for other visited levels, which uses the equation {{sfrac|(count * [[rn2]](25)) + 50|100}} where "count" is the number of known maps.{{refsrc|src/read.c|835|nethack=3.6.7}} Sokoban maps are not forgotten in any of the above cases since they are always automapped, and each Sokoban map visited adds 2 to "percent" in the aforementioned equation.{{refsrc|src/read.c|801|nethack=3.6.7}}{{refsrc|src/read.c|863|nethack=3.6.7}}

=== Objects ===

There is a {{frac|1|3}} chance that you forget 1% to 25% of your object discoveries. This includes formal identifications, any [[Name#.23naming a class of items|class names]] you have given, and any pre-discoveries that you started with by virtue of your [[role]] or your [[race]].

You do not forget the names of any [[Name#.23naming individual items|individually named]] objects.

=== Spells ===
If the scroll is non-blessed, anywhere between 1 and all of the character's known [[spell]]s have their "turns remaining" counter set to zero.

If you are confused, NetHack rolls the base number twice and takes the higher result. If you pass a [[luck]] check, instead of forgetting the base number of spells, you forget a random number of spells between 1 and the base number.

=== Attributes ===
Your [[wisdom]] is abused once for reading the scroll and once again for each spell forgotten.

== Messages ==
{{message|Thinking of Maud you forget everything else.}}
{{message|Who was that [[Maud]] person anyway?|You read a scroll of amnesia.}}
{{message|As your mind turns inward on itself, you forget everything else.|You, a character named Maud, read a scroll of amnesia. [[TDTTOE]].}}
{{message|Your mind releases itself from mundane concerns.|You read a scroll of amnesia while [[hallucinating]].}}

== Identification ==

Scrolls of amnesia auto-identify when read. The auto-identification happens after all the forgetting effects.

Monsters will not read them.

== Strategy ==

Scrolls of amnesia are useless, making them a perfect candidate for [[blanking]]. Because the effects of reading it are so problematic, it is best to ensure that an unidentified scroll is not amnesia before reading it. If [[price identification]] reveals a scroll's base price as 200zm, you should avoid reading it unless scrolls of amnesia are already identified.

The names of individually named objects are never forgotten, so you can use these for amnesia-proof [[notetaking]].

== History ==

Forgetting only one spell is a [[Bugs in NetHack 3.4.3|bug in NetHack 3.4.3]]. The intended behavior is to forget between 1 and all of your spells starting at the bottom of your [[spellcasting]] menu. If you are confused, the number of forgotten spells is supposed to be +1 on top of that (limited to all of them of course).

Prior to [[NetHack 3.6.0]], this scroll could be used to manage which [[spellbook]]s you get [[gift]]ed. Before reading the scroll, use {{kbd|+}} to sort the [[spellcasting]] menu so that forgotten spells or spells you want a book for appear last. [[Prayer#Favors and gifts|Altar farming]] will then be more likely select these spellbooks over ones still present.

Another use could be to avoid blanking spellbooks—you can read them arbitrarily often provided you do not already have the spell in your [[spellcasting]] menu. NetHack 3.6.1 only removes memory of the spell but does not take it away from the list.
