Notes[edit | edit source]
- As Jacob and Esau, it's not possible to cycle between three books to give both characters the transformation's effect. Each characters needs to pick up three different books, meaning six books in total.
- Picking up a cloned book by using Diplopia or Crooked Penny will count to the transformation, meaning that it can be obtained by picking up less than three books.
Trivia[edit | edit source]
- 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.
