The next thing to do on Diablo 3 is a short quest called The Black Soulstone when you by D3 account. After you’ve returned to the Desolate Sands, you will have to start searching for a passageway leading to the last portal. It’s best to explore the northern part of the location while moving close to the edges of the map. Find out more about this quest in the article below!
The Black Soulstone Quest for Diablo 3 Account Holders
This will begin automatically after you’ve finished the previous quest. Thread the Ancient Path until you find yourself in the Desolate Sands. This is actually a very large area compared to most, and will take you some time to explore and find the two dungeons you are looking for. As such, this is a good location to farm some loot and gold for your D3 account. Once you find the Cave of the Betrayer, enter it and fight through the levels until you find the Blood of Zoltun Kulle. Next, exit the cave and search the Desolate Sands again for the Vault of the Assassin. Explore the vault and locate the next Blood of Zoltun Kulle. Both dungeons are very simple, no boss fights and no events that will heavily slow you down.
To the Terminus for Diablo 3 Account Holders
Now that you have the Bloods in your possession, search the perimeter of the Desolate Sands until you find a small square zone off the edge of the map. You will find the Archives of Zoltun Kulle here, and the quest will update, telling you to go to the Terminus. Simply click on the Archives to enter the next zone. After the conversation plays, head deeper into the Archives and at some point you will reach a red raised platform. Here you will have another conversation and be given the choice of entering one of the next areas. It does not matter which you choose first as you will have to do both, anyway.
To the Unknown Depths and the Storm Halls for Diablo 3 Account Holders
The area to the left is the Unknown Depths. Crawl through the dungeon, defeating hostiles on the way and picking up useful items until you reach the end of the area. You will see a ring with dark red runes spinning around a central pedestal. Destroy the arcane locks to exit the area. The second area is the Storm Halls. Kill all foes blocking your path until you reach the end, where you will have to destroy the arcane locks again, and then exit back to the Terminus.
To the Realm of Shadow for Diablo 3 Account Holders
Once you return to the Terminus, venture to the center (the northeastern platform) and enter the Realm of Shadow. Once inside, you must find Zoltun Kulle’s body. This new area is pretty much the same as the previous dungeons, save for the gaseous haze over the entire area. Much like the original Diablo dungeon crawls, hack-and-slash your way to the end of the area and reach a blue glowing circle, wherein the body of Zoltun Kulle resides. Click on it to obtain the body. This will update the quest.
To the Soulstone Chamber for Diablo 3 Account Holders
There will be a boss battle ahead, so make sure you are prepared. Stack up on items, sell some if you’re almost overloaded, and buy some gear on your D3 account if you need to. Return to the Terminus, where Leah will be waiting for you. Speak with her to play the cutscene. Afterwards, walk to the center of the Terminus and enter the portal to the Soulstone Chamber.
Defeating Zoltun Kulle for Diablo 3 Account Holders
Zoltun will have large constructs that aide him throughout the battle. You can either focus on taking them out first, or if you can tank the minimal damage they cause, then ignore them so you can concentrate on Zoltun. The boss fight against Z
oltun isn’t actually that complex. He uses regular fireball attacks which he throws at his target. He also occasionally uses a bubble that absorbs any damage, plus a lightning bolt attack that radiates out from his body. Once he is defeated, move in and claim the Black Soulstone, and then take it back to Adria at the Hidden Camp to complete the quest on your Diablo 3 account.
