  • Book and quill & written book
    • Editable Books – Book and quill, crafted using a book, feather, and ink sac
      • When a book and quill is made, it can be right-clicked to open a screen that allows you to type the book.
      • Pressing “Done" will save whatever was typed and allow you to edit the book again later, yet will not “sign" it.
      • When “signing" a book, it will allow you to choose a title up to 16 characters long and disable editing of the book, the Book and Quill then becomes a written book, with the icon changing along with the label
