Books (Polarities Mod)

Books are a new class of tool sold by the Ghostwriter for 5. Each is (usually) themed around a specific boss and are only sold upon its defeat, providing an infinite buff themed around that boss when used. Only one buff from a book can be active at a time unless the Reading Glasses or Spectral Lenses are equipped, which allow two or three simultaneously, respectively (except for the Strange Obituary, which does not count as a book buff for these purposes). Additionally, some books' titles reference various well-known real-life novels and book series, which are noted on their individual pages. All books are of the rarity and sell for 1.

Books can also be placed in the world as furniture items; two can be placed in the same tile, allowing them to be used as decoration.
