The book of balance is a book held in place of a shield, and is the god book aligned with Guthix. It can be received as a reward from the Horror from the Deep quest. Books of balance must be made using all four torn Guthix pages which can be purchased from other players or obtained from Treasure Trails. It also allows players with a Prayer level of 50 or greater to bless holy symbols and unholy symbols, at the cost of 6 prayer points per blessing (compared to 4 points lost when using the other two main god book).
Equipping a book of balance allows the player to preach and perform ceremonies, such as blessing, last rites, and wedding rites, by operating it (none of which have any effect on the game itself, and are simply recited lines of text), costing 25% of the player’s special attack energy.
Lost books of balance can be reclaimed by speaking to Jossik, complete with all pages that have been added, for no cost. Alternatively, for those who do not wish to travel to the lighthouse, Perdu will return them to players for 12,000 coins.
Filling the Book of balance currently costs 21,364 coins when buying each page individually or 30,845 when buying the item set.
The player may perform certain ceremonies by right-clicking the book and selecting “Preach.” The following are the options that appear when preaching and what the player says upon selecting them.
