Curse of Strahd
Tome of Strahd
The Tome of Strahd is an ancient book documenting Strahd's transformation as well as numerous details of Barovia. It grants a +2 Intelligence bonus to any creature that attunes to it. Further, a creature may use the book to learn something about Barovia, effectively gaining a +5 on a check to identify a piece of Barovian lore. The book is terribly organized and difficult to read, however, so this use takes 5 minutes.
