The scariest part about these books is that they AREN'T REAL BOOKS AT ALL! They're self-published!
— Spellbooks publicity blurb
The Unfilled Fancy Spellbook is an unlockable item given to players who earn the achievement Hat Out of Hell. It is an empty spellbook with no pages that requires Spellbook Pages in order to be filled. Spellbook pages can be found in haunted Halloween gifts and by earning the achievement The Mann-tastic Four. When three pages have been inserted into the book, it is replaced with the Fancy Spellbook.
