==When Used==

{{useitem|
text=You have no idea what this thing is for.}}

*''From inventory, after consultation:''
{{useitem|
text=Following The Oracle's advice, you treat the plus sign as a book, and read it. It describes, in great detail, a place called the Dungeons of Doom. The first chapter teaches you that the Enormous Greater-Than Sign is actually the stairway leading to these dungeons, and the rest of the book teaches you how to recognize the items and monsters contained within its halls.

After you're done reading the book, it vanishes in a puff of obsolescence.

You dig through your inventory and identify all of the crap you already picked up down there:
{{acquire|item=small box|num=some}}
{{acquire|item=large box|num=some}}
{{acquire|item=magic whistle|num=some}}
{{acquire|item=baby killer bee|num=some}}
{{acquire|item=royal jelly|num=some}}
{{acquire|item=mind flayer corpse|num=some}}
{{acquire|item=cornuthaum|num=some}}
{{acquire|item=vorpal blade|num=some}}
{{acquire|item=pile of gold coins|num=some}}
{{acquire|item=ring of aggravate monster|num=some}}}}

==Notes==
*Grants access to [[The Dungeons of Doom]].
*The items given are converted from the items sourced from [[the Enormous Greater-Than Sign]].
*The conversion into new items is done according to some random function; a Percent-Sign that drops from a lowercase a will not automatically turn into royal jelly, for example.
*Items from [[the Enormous Greater-Than Sign]] not in main inventory (Display Case, Hagnk's, Closet) are ''not'' converted – according to a bug report response, this is intended behavior to let players amass a collection of unconverted items if they so wish.

==References==
*In ''[[wikipedia:NetHack|NetHack]]'', a plus sign represents a spellbook (or a closed door).
*In the use text, "a puff of obsolescence" alludes to the message received in ''NetHack'' after using a throne, namely "The throne vanishes in a puff of logic", which refers in turn to ''[[wikipedia:The Hitchhiker's Guide to the Galaxy|The Hitchhiker's Guide to the Galaxy]]''.
