Zamorak's Book of Chaos detail

Zamorak's Book of Chaos, formerly the Unholy book, is a book held in the pocket slot. For information on how to acquire a god book, see the god books article. Zamorak's Book of Chaos must be made using all four torn Zamorak pages which can be purchased from other players, obtained from treasure trails or by cremating a vyrewatch. With Zamorak's Book of Chaos, a player can preach and perform ceremonies, such as blessing, last rites, and wedding rites by operating it. Also, if a player's Prayer level is 50 or higher, they can bless Unholy symbols with Zamorak's Book of Chaos by expending 40 Prayer points for each symbol.

Lost books of chaos can be reclaimed by speaking to Jossik at the lighthouse, or from a player-owned house bookcase, complete with all pages that have been added, for 100,000 coins. However, the book will lose all its remaining charges, requiring the player to add additional pages in order to activate the passive effect.

After completion of One Piercing Note, if the book has all four pages, it can be used to create an illuminated book of chaos and unlock the god book off-hand override. This requires 60 Crafting and 60 Prayer, and grants 10,000 Prayer and 10,000 Crafting experience (for the first time only). The book of chaos is not consumed in the process.

Filling Zamorak's Book of Chaos with all pages currently costs 332,028 coins.

The book of chaos can be activated like scrimshaw to provide a passive combat effect. The book can be recharged with any Zamorak page, giving 45 minutes of active time per page. This is shared, unchanged, with the illuminated book.

The passive has a 5% chance per hit to activate. When it activates, a dark explosion hits the target and the surrounding targets in a 3x3 area for 150-250% damage (split over all targets) (PvP: 50-150%). Based on K'ril Tsutsaroth's 'YARRR' attack.


The following text is transcluded from Transcript:Zamorak's Book of Chaos.
Wedding Ceremony

  • May your union not be harmonious, but may your conflicts make you stronger, in Zamorak's name, now two are one.
Last Rites

  • The weak deserve to die, so the strong may flourish. This is the creed of Zamorak.

  • May you reject all safe paths, and embrace all challenges. Zamorak bring you strength.

  • As Zamorak seized the power of godhood, so should you seize all power within your grasp, find strength in the chaos of Zamorak!
