Let’s start our guide by first talking about the hidden or secret Library of Zoltun Kulle. The library is located in the deserts of Kehjistan and is filled with demons and traps. Players are advised to proceed with caution.

But first, you need to reach the place to discover the secrets it contains. You can access the location during the Shassar quest chain. We would recommend at least being level 35 before starting this quest. 

The Library of Zoltun Kulle is the home of many secrets in Diablo Immortal, such as the secret Chamber Zone Event and some Hidden Lairs. In our guide, we will give you a general overview of both of them.

Once you have made it to the Library of Zoltun Kulle, then the secret event will be available for you. What is great is that the event does not have a reset timer, meaning that players can do the event as many times as they want. It is great for players who are farming for certain resources in the secret locations of Diablo immortal.

But to unlock this event. Players need to complete the lengthy Zoltun Kulle story quest. The Zoltun Kulle quest includes uncovering secrets in the Library of Zoltun Kulle; therefore, if you are interested, then consider reading the Diablo Immortal Lost Pages guide and learn about Shassar & Zoltun Kulle Quests.

To complete the secret event. Players need to do some grinding and collect 5 Lost Tome Pages.

How to get Lost Tome Pages

As we said before, in order to complete the event, Players need to find the Lost Tome Pages. The only way to get the pages is by killing enemies in the library. The pages are dropped randomly. 

We would advise picking up any Lost Tome Pages you can find because you are not alone in the zone. There are other players in the zone, and pages are not exclusively available for each player. 

Once you have collected five pages, then you need to craft a Portal Tome. A Portal Tome requires 5 Lost Tome Pages. You can use the Portal Tome to access one of Kulle’s Secret Chambers.

After using the Portal Tome, one of three things will happen. Either you will summon the Fleshcraft Hydra, the Sandstone Golem, or a portal that will teleport you to a secret treasure chamber.

These Hidden Lairs in Diablo immortal are very similar to your standard mini-dungeons. You have the choice to either do these Hidden Lairs solo or with a team. These lairs are found randomly; therefore, it is never a bad thing to explore the world of Diablo immortal whenever you have some free time. Exploration is pretty much required for discovering secrets in Diablo Immortal.

These lairs are spawned randomly, and they do not have a fixed location. Exploring these Hidden Lairs rewards you with certain materials; therefore, players should always invest some extra time in exploring these lairs.

When a hidden lair becomes available to you, then you will have a limited time to access it before it moves to a second location. If you wish to complete a hidden lair with a team, then you need to form a team first before entering the lair.

There are numerous Hidden Lairs in Diablo immortal such as

Objectives and Rewards of Hidden Lairs

Most lairs have different objectives depending on the level requirements of those lairs. Most objectives are pretty straightforward. As far as main objectives go, you only need to defeat the Guardian of the lair. They are your average game bosses, and you will be rewarded with loot after defeating them.

You will also encounter secondary objectives while exploring these Hidden Lairs. If you invest extra time and complete these secondary objectives before facing the boss of the lair, then it will increase your reward for completing a hidden lair. We would recommend fully exploring these lairs first—no need to rush.

As for the rewards, completing Hidden Lairs rewards you with different materials and other useful items. Some of the reward drops of these lairs change daily; therefore, try participating in these lairs daily to get different materials.

One thing to note is that some of these Hidden Lairs also have secret sections, so keep your eyes peeled for them. You can discover these secret sections after defeating the guardian of the lair. These secret sections offer tougher enemies and better loot.
