The Tablet is a general term used to describe the original pages of the Book of Prophecy. These pages come in blue, gold, and green. In most cases, blue are recipes for various item codes, gold are instant level ups to your health and mana, and green are puzzle item codes. To open a puzzle item code from a green tablet, you must click the picture on the other page from the book and complete the puzzle. The first I achieved was the Ice Wings.
