Have the Diablo Immortal Hidden Lair locations been eluding you? If you’ve been playing Blizzard’s mobile RPG game for any length of time, you’ve probably become very familiar with one particular notification: ‘A Hidden Lair has opened in this zone’. Their locations may not be immediately apparent, but don’t be tempted to ignore them. Regardless of what Diablo Immortal class you are, they are well worth investigating for the upgrades they can provide.
If you’ve been tripped up by Diablo Immortal Hidden Lairs, much like a lot of new players to this free-to-play loot bonanza, this guide is what you need. We’ve got the details on what Hidden Lairs are, what they look like, and all their locations.
What are Hidden Lairs in Diablo Immortal?
Diablo Immortal Hidden Lairs are mini-dungeons that can be completed quickly, easily, and solo if you prefer. Not only are they a decent source of XP and legendary items for leveling up, they’re also a fantastic way to acquire normal Diablo Immortal gems without opening your wallet. The only trouble is that Hidden Lairs are, well, hidden. Don’t expect a map marker or signposting of any kind; the only way to find them is to hunt them down yourself.
If this weren’t elusive enough, there are a few additional caveats to how Hidden Lairs work. Once one has opened, you’ve only got 10 minutes to find the Hidden Lair before it moves to another location. They operate on a ‘first come, first served’ basis – if someone else enters a Hidden Lair then it will no longer be accessible to you. You can work this in your favour by keeping an eye on Diablo Immortal’s party finder when one opens. If someone in your group enters the lair, you’ll all receive a prompt to battle through it together. There’s strength in numbers when it comes to both finding and fighting through a Hidden Lair, so cut down on the competition by grouping up.
Where to find Diablo Immortal Hidden Lair locations
Thankfully, Hidden Lair locations aren’t entirely random. Each zone contains several spawn points, though they’re scattered across the map and their numbers vary wildly depending on the zone. Hidden Lairs all look the same in each area, so once you know what to look for in each zone you’ll be able to pick them out of the environment with ease.
Here are what Hidden Lairs look like when you’re in each area:
- Ashwold Cemetery: Mausoleum
- Dark Wood: Tunnel
- Shassar Sea: Well
- Library of Zoltun Kulle: Well
- Bilefen: Cave
- Mount Zavain: Cave
- Frozen Tundra: Altar
- Realm of Damnation: Altar
The entrance will glow blue or yellow once you’re in the vicinity, and a marker will be added to your minimap. We’ve compiled all the Hidden Lair locations, explained what they look like in every zone, and marked them on every map, so you can be sure to know where to look once the notification pops up.

Diablo Immortal Hidden Lair rewards
Regardless of how many floors a Hidden Lair has, it’ll conclude in a fight against a Diablo Immortal Lair Guardian. This mini-boss is an Elite Monster that will drop a Rank 1 normal gem of any random colour.

Once the Lair Guardian is slain, there’s a chance a portal will spawn, granting you access to an additional floor complete with its own Lair Guardian. It also comes equipped with a Blacksmith, so you can salvage items and free up any additional inventory space required before continuing onwards. Once you’ve cleared everything, interact with the portal that will spawn nearby to exit the Hidden Lair.
General Diablo Immortal Hidden Lair tips
Diablo Immortal Hidden Lairs can provide you with ample rewards once you clear them, but there’s a couple of things you can be doing to make the most of your time fighting through them
- Don’t neglect the bonus XP received from Massacre Kills. Hidden Lairs are typically one continuous narrow corridor, so work this to your advantage by pulling a large group of enemies at once and killing them simultaneously to net that bonus.
- While we would recommend prioritising Hidden Lairs when they become available, there is a limit to the amount of gems you can receive from them per day. The hidden cap appears to max out at around two or three Hidden Lairs per day, so once you start seeing a decline in the rewards you receive it’s wise to abandon pursuit of them until tomorrow.
- There’s no set time limit when you’re in a Hidden Lair, so take care to complete all the secondary objectives within the lair before engaging the Lair Guardian. These objectives generally involve interacting with objects or defeating a specific group of enemies, so you don’t have to go too far out of your way to complete them.
Once you have all the Diablo Immortal Hidden Lair locations memorised, tracking them down and clearing them of loot will become second nature – and the gems you’ll acquire will allow you to fight through them faster than ever.
