Where is the Underground Passage in Diablo 2: Resurrected?
In the first act of Diablo II: Resurrected, players must complete the quest The Search for Cain. To find Deckard Cain players must make their way to Tristram by using the Cairn Stones, which must be activated in a particular order. Players can discover this specific order by traveling to Dark Wood and locating the Tree of Inifuss. However, Dark Wood is only able to be accessed via an Underground Passage.
Where is the Underground Passage in Diablo 2?
The Underground Passage that leads to Dark Wood can be found in Stony Field, the same place players must later activate the Cairn Stones. The maps in Diablo II: Resurrected are randomized, so players will have to wander around Stony Field until they discover a hole in the ground marked as the Underground Passage.
The Underground Passage has two levels for players looking for a battle, but the exit to Dark Wood is on the first level, so it is not necessary for players to clear out the entire area. Once players have reached Dark Wood they can continue through the steps of The Search for Cain and eventually save the Horadrim Sage who will then identify items for the player free of charge.
