Whether you’re a seasoned player or a newcomer, understanding this God Book can elevate your gameplay, especially in PvP and magic-focused scenarios. This comprehensive guide dives into everything you need to know about the Book of Darkness, from acquisition to its practical uses, ensuring you maximize its potential.
The Book of Darkness is a God Book aligned with Zaros, one of the most enigmatic deities in OSRS lore.

Key Features of the Book of Darkness
- Zaros Alignment: Reflects the lore of the forgotten god, adding a unique flavor to your gear.
- Prayer Bonus: Provides +5 Prayer, ideal for prolonged combat sessions.
- Preaching Ability: Allows players to perform ceremonies like blessings and last rites, though these are purely cosmetic.
- PvP Utility: Offers decent magic defense for its low cost, making it a staple for budget builds.
How to Obtain the Book of Darkness
Getting your hands on the Book of Darkness involves a few steps, but it’s straightforward once you know the process. Here’s a breakdown to guide you through.
Step 1: Complete Horror from the Deep
The journey begins with the Horror from the Deep quest. This quest is essential as it unlocks access to God Books via Jossik at the Lighthouse. You’ll need:
Once completed, speak to Jossik, who offers a Damaged Book. You can choose the Book of Darkness (Zaros) for 5,000 coins.
Step 2: Collecting Ancient Pages
The Damaged Book is incomplete without its four Ancient pages. These can be obtained in two ways:
- Treasure Trails: Clue scrolls (hard or elite) may reward Ancient pages.
- Grand Exchange: Purchase individual pages or a Book of Darkness page set for convenience.
As of recent market trends, filling the book costs around 660,410 coins for individual pages or 708,299 coins for the set, though prices fluctuate.
Step 3: Reclaiming Lost Books
If you lose your Book of Darkness, don’t panic. Jossik will replace it for free, including any pages already added. Alternatively, Perdu charges 14,000 coins for a replacement if you prefer not to travel to the Lighthouse.
Stats and Bonuses
The Book of Darkness isn’t just a cosmetic item; it offers practical bonuses that make it viable in various scenarios. Below is a detailed look at its stats.
Combat Bonuses
Stat | Bonus |

Defence (Stab) | +10 |
Defence (Slash) | +10 |
Defence (Crush) | +10 |
Defence (Magic) | +10 |

Practical Uses in Gameplay
The Book of Darkness shines in specific niches, particularly for players who prioritize affordability and versatility. Here’s how it fits into OSRS gameplay.
PvP Scenarios
In player-versus-player combat, the Book of Darkness is a budget-friendly option. Its magic defense and prayer bonus make it ideal for:
- Pure Accounts: 1 Defence pures benefit from its bonuses without sacrificing combat levels.
- Deep Wilderness: Since it’s reclaimable for free, it’s low-risk for high-stakes fights.
- Hybrid Setups: Pairs well with magic-based gear for hybrid PvP builds.
PvM Applications
While not a top-tier choice for high-end PvM, the Book of Darkness has its place:
- Low-Level Bossing: Useful for early-game bosses like Barrows or Giant Mole.
- Prayer Conservation: The +5 Prayer bonus extends prayer point duration, handy for Slayer tasks.
Cosmetic and Roleplay Value
Beyond stats, the Book of Darkness offers unique preaching options, letting you recite Zarosian phrases like “Power to the Great Lord!” These are purely for fun but add depth for roleplayers or those who enjoy OSRS’s lore.
Tips for Maximizing Value
To get the most out of your Book of Darkness, consider these strategies to enhance its utility and save resources.
Cost-Effective Acquisition
Save coins by:
- Completing clue scrolls yourself to avoid Grand Exchange costs.
- Buying the page set during market dips, as prices can vary significantly.
- Using the Grand Exchange clerk’s “Sets” option to convert pages for easier storage.
Ornament Kit for Aesthetics
The Book of Darkness (or) variant, created with a Shattered Relics variety ornament kit, adds a visual flair without changing stats. It’s reversible, so you can experiment without losing the kit. This is perfect for players who want to stand out at the Grand Exchange or in PvP lobbies.
Pairing with Gear
Optimize your setup by combining the Book of Darkness with:
- Ancient Staff: Enhances the Zarosian theme and boosts magic accuracy.
- Mystic Robes: Affordable magic gear that complements its defensive bonuses.
- God Capes: A Mage Arena cape adds magic attack, rounding out your build.
When to Upgrade
While the Book of Darkness is excellent for budget builds, consider upgrading to a Mage’s Book or Arcane Spirit Shield for endgame content like Theatre of Blood or high-level PvP. These offer superior bonuses but come with a heftier price tag.
The Book of Darkness is a versatile and accessible item that holds its own in OSRS’s competitive landscape. Whether you’re diving into PvP, tackling early-game bosses, or simply embracing Zaros’s lore, this God Book offers a blend of utility and charm.
