Tome of Knowledge (ProjectE)

The Tome of Knowledge is an item added by ProjectE. The Tome of Knowledge can be consumed by a Transmutation Table or Tablet (left-clicking on the GUI's fire slot with the Tome) to allow the player to transmute all items that have EMC. If for whatever reason you would like to unlearn all of the items from the book, simply get another Tome of Knowledge (or the same one) and put it into the “Unlearn” GUI slot (left-click on the GUI’s book with a red x slot with the Tome).

Note: In later versions of ProjectE, there is no Official crafting recipe and can only be obtained in Creative or through commands.
