Diablo Immortal has several mini-dungeons called Hidden Lairs that you will come across while leveling your character through the main campaign. Completing a Hidden Lair will reward you with normal gems, which is something you can ignore if you are looking to level up fast to get early access to the endgame.
If you are still bent on finding and clearing these mini-dungeons though, the following guide will provide you with the locations of the Hidden Lairs in Diablo Immortal.
Diablo Immortal Hidden Lairs
The problem with Hidden Lairs is that they are hard to find. They firstly have a rare spawn rate, meaning that you cannot just head to a waypoint to always find an available Hidden Lair.
Secondly, you will be informed when a Hidden Lair has opened in your zone. However, you will then need to find its entrance through exploration. If you fail to find the entrance within 10 minutes, the Hidden Lair will disappear and will then respawn at a different location.
Fortunately, the entrances to these mini-dungeons are not that random. They have particular locations in each zone.
Below are the possible spawning locations of Hidden Lairs in each zone
Ashwood Cemetery Hidden Lair Locations
Dark Wood Hidden Lair Locations
Shassar Sea Hidden Lair Locations
Library of Zoltun Kulle Hidden Lair Locations
Bilefen Hidden Lair Locations
Mount Zavain Hidden Lair Locations
Frozen Tundra Hidden Lair Locations
Realm of Damnation Hidden Lair Locations
Hidden Lairs Objectives
Once you’ve entered a Hidden Lair either solo or with allies, you will be given simple tasks to complete that reward you with a Rank 1 normal gem. The whole point of completing Hidden Lairs is to get these normal gems. Hence, make sure to complete those tasks.
In order to complete a Hidden Lair, you will have to defeat its mini-boss at the end of the floor. When you finally kill the mini-boss, a blue portal will spawn to get you out of there.
However, there is a chance that a blue portal will spawn alongside a red portal. That red portal takes you to the second floor of the mini-dungeon. If you click on the blue portal, you will not be able to return.
The second floor will have a blacksmith at the start to help you Salvage items. The second floor will also give you another set of simple tasks as well as another mini-boss to defeat for more Rank 1 normal gems.
Hidden Lairs only have a chance to have two floors. You will never find a second red portal on the second floor.
As for your rewards, you’ll receive a chest that may contain the following Rank 1 normal gems: Aquamarine, Citrine, Ruby, Sapphire, Topaz, and Tourmaline.
Hidden Lair Rewards
Hidden Lairs offer a bunch of rewards. You get these once you defeat the mini boss of the lair, called Lair Guardian.
Every Lair Guardian is guaranteed to drop one Rank 1 normal gem for you. This is the base reward for every lain. However, you do get additional rewards sometimes as well.
There is always a chance for a portal to open up when you defeat the Lair Guardian. These portals grant you access to additional levels of the lair with their own Lair Guardians. These can then give you further gems and rewards for defeating them.
How to Clear Hidden Lairs
Here are a few helpful tips that will help you be more efficient when farming these hidden lairs and help you get the maximum you can get out of these lairs.
Focus on Massacre Kills. These hidden lairs are usually in the form of a long single path and you can kill multiple enemies at once easily here. This is a free bonus that you can get for yourself, just by pulling enemies close before you take them out.
Don’t overdo the hidden lairs. There is a limit to the number of gems you can get from these. After 3-4 gems, you will notice a decline in the rewards of the subsequent lairs that you complete. This reward cap is for every 24 hours, so consider these lairs as a part of your daily challenges rather than a single grind run.
Make sure you complete the lair in its entirety. Since these lairs are pretty small, make sure you complete the secondary objectives as well before you head on to face the Lair Guardian. These objectives are quite simple and you would rarely have to go out of your way to complete them.
