Diablo 2 Resurrected Cairn Stones and Underground Passage Location
Cairn Stones are part of a lengthy quest that pits you against another unique boss, so make sure you come prepared.
Diablo 2 Resurrected Cairn Stones are easy to find, but require many more steps to activate, including a trip through the Underground Passage dungeon.
Before you can do anything with the Cairn Stones, you’ll have to take on another unique boss and learn the secrets of the portal they guard. Fortunately, everything you need is fairly close together.
You will need to venture through the Stony Field, Underground Passage, and Dark Wood in search of the Tree and Scroll of Inifuss - here's where you need to go!
Diablo 2 Resurrected Cairn Stones | Where to find Cairn Stones and Deckard Cain
The Search for Cain quest tasks you with finding six Cairn Stones in the Stony Field, then activating them in a specific order to solve the puzzle. Getting to the Stony Field and actually activating the stones is a bit of an ordeal, though.
The road through Cold Plains splits, and one of the forks takes you to the Stony Field area. The other is where you visited the Burial Grounds earlier. Where the Cairn Stones actually end up depends on chance. Like much of Diablo 2, the Stony Field map is randomly generated, so the Cairn Stone locations may vary depending on your game.
Finding them is just the start, though. Activating them requires a small detour through the Dark Woods to find the Tree of Inifuss.
Diablo 2 Resurrected Underground Passage | Tree of Inifuss location
Also in the Stony Field, usually very close to the Cairn Stones is the Underground Passage that connects to Dark Wood. You're looking for an entrance along one of the edges of the Stony Field. So if you're lost, focus on filling in the mini-map until you can pick out what you're looking for.
Head through level 1 of the Underground Passage and deal with the (many) threats along the way. At some point on the first level, you will find the exit to the Dark Wood.
Like the Cairns themselves, the Tree location will vary from game to game once you reach the other side. Wherever it ends up, you’ll need to fight or get around the Treehead Woodfist unique boss to interact with the Tree of Inifuss.
Once that’s done, go back to Akara. Interact with the stones in a specific order, which will also vary from game to game, and a portal opens leading you to Cain — plus a bunch of additional enemies. Deal with them to finish the quest. Grab the Moldy Tome from an altar in Stony Field before you leave to start the Forgotten Tower quest as well.
Finishing both quests is a good idea before taking on Diablo 2 Resurrected’s Tools of the Trade quest with its bigger difficulty spike. You’ll need the extra boosts from leveling up, since resetting stats isn’t the easiest option.

Activision Blizzard is currently dealing with the fallout of a major lawsuit with the State of California over widespread harassment, which has so far gotten Blizzard’s president and head of HR ousted. In a statement addressing the lawsuit, CEO Bobby Kotick said those responsible will be held accountable, though many employees feel it ignored their demands.
In the wake of the lawsuit, Activision has been sued by shareholders for allegedly hiding the investigation that lead to the suit, and a number of sponsors are pulling back from Overwatch and Call of Duty Leagues. Many within the group’s various studios have formed a coalition to demand real action from company leaders.
