. Since the maps in D2 Resurrected are randomized, we can’t show you the exact location, but go through this whole area and you will eventually find it. The entrance itself looks like a hole leading to an underground cavern. The Underground Passage has two levels. To entrance to the Dark Wood can be found on the first level, so if you are rushing to complete this quest, you don’t have to go to the second level. So, as soon as you have found the way to Dark Wood, go there. In the Dark Wood, you will need to locate the Tree of Inifuss. Interacting with this Tree will give you the Scroll of Inifuss. You then need to take this back to Akara.
After this, return to the Stony Field and search for the Cairn Stones. You will need to touch these in the correct sequence. This sequence is on the Scroll of Inifuss, so follow its instructions. Once this is done, a portal to Tristram will open. Go through it, and you will find Deckard Cain in the middle of the destroyed town. It’s very much worth saving him, since he will then identify items for free.
