291.) The Biographicon

This book contains a running account of the current reader's life, written in the style of a pop biography. Close examination of the text will occasionally reveal salient facts and details that there should be no way of knowing; foreshadowing of the future, instant answers to NP-hard logic problems, details of what the villain is doing and thinking right now even though they have a mind blank up, et cetera. It doesn't reveal these on demand, only insofar as they are salient to the overarching story of the character's life, and it doesn't write itself past the present time (in the reader's personal timeline, in cases where it makes a difference).

In games and editions where all artifacts carry subtle curses, excess reliance on he book's hints may lead to a feedback loop where the book's holder is compelled to spend every minute of spare time narcissistically reading and rereading the book and take 1d2 charisma damage per day until they either succeed at a willpower save (DC 19) or the book is taken from them forcibly. During this time the book itself will criticize them for obsessing over it in the sentences covering those days.

The existence of this item could be used by the DM as a means to reveal lore that there would otherwise be no good way to introduce and/or to get the party past puzzles and quandries that they are stuck on.
