Notes[ | ]
- As Jacob and Esau / Tainted Lazarus, it's not possible to cycle between three books to give both characters the transformation's effect. Each character needs to pick up three different books, meaning six books in total.
- Unlike 20/20, the damage of doubled tears is not reduced. Each of the doubled tear shots does full damage.
Trivia[ | ]
- A bookworm is a person who's devoted to reading, especially books.
- Book of Virtues is the only passive item to contribute to the transformation.
- Bookworm can be very easily attained by going into a Library.
