Fuming Potato Book

Fuming Potato Book is an item that slightly raises stats of weapon and armor pieces. It works similarly to the Hot Potato Book but is able to exceed its 10 book limit, instead being limited to 15. A Fuming Potato Book can be applied to any item, even if it has 10 Hot Potato Books on it already. However, the Fuming Potato Books can be used instead of Hot Potato Books. This information was given in a stream by YouTuber and Streamer ThirtyVirus on May 19, 2020. ThirtyVirus was given Fuming Potato Books by an admin and used them on a weapon that they had.

Usage
A Fuming Potato Book can be added to any item that Hot Potato Books can be added to, and will bypass the limit from 10 Hot Potato Books on that item, up to a limit of 15 potato books (hot and fuming potato books combined). However, a Fuming Potato Book will still gives the same stats as a Hot Potato Book, but allows you apply up to 5 Fuming Potato Books after the cap of 10 Hot Potato Books.

Trivia

 * This was first sold by the admin Jayavarmen to the YouTuber Refraction for 2 billion coins.
 * There was a bug with the Fuming Potato Book, where each book would add a +4 bonus instead of a +2 bonus and remove 2 anvil uses instead of 1. This means that the Fuming Potato Book limit was only 8 or 3 if 10 Hot Potato Books were already added.
