Blood and Sand Diablo III Guide
Last update: 11 May 2016
The only way to begin this new quest is to talk to Zoltun Kulle's ghost in the Hidden Camp. Leah will be helping you during this mission, however you'll also be carrying Kulle's head with you.
Enter the Ancient Waterway in Dahlgur Oasis
Return to the Dahlgur Oasis and travel close to the edges of the map until you locate a passageway to the next location. Choose a narrow path and follow it until you come across a closed door. Zoltun Kulle will open the door for you.
Western flow control level pulled
Eastern flow control level pulled
Open the entrance to the Waterlogged Passage
Enter the Ancient Waterway. Talk to the Emperor Hakan II and then choose the passageway leading to the Western Channel.
Watch out for Electric Eel's here, because they'll be attacking you in groups. You may also encounter Noxious Guardians, Carrion Bats (they inflict lightning damage), the Accursed (they explode when they die) and more common creatures like skeletons.
As for the location itself, it's a network of corridors. Continue exploring it until you locate a passageway to Western Flow Control Room.
You should find a lever upon entering the new area and you must interact with it, completing one of the objectives. Notice that the game has unlocked a passageway to the Eastern Channel.
Start exploring the sewers again. The opponents here are the same as in the previous channel and once again your objective is to locate an exit. Go to the Eastern Flow Control Room, pull the lever and use a newly unlocked passageway. The game will open an entrance to the Ancient Waterway.
Enter the Waterlogged Passage from the Ancient Waterway
All you have to do is to use the newly opened passageway.
Kill the Betrayed
Enter the Waterlogged Passage. Head forward to encounter a "Talking Barrel" and a group of Betrayed. You must kill them all.
Break the Talking Barrel
Once you've dealt with the monsters destroy the barrel to find out that a man was trapped inside.
Talk to Covetous Shen
Initiate a conversation with the Covetous Shen. He will ask you for help in retrieving an item and he'll also join your team.
Find the Crucible in the Hidden Aqueducts
Continue moving forward until you've reached an exit from this location.
You may begin exploring the Hidden Aqueduct and it shouldn't come a surprise that you'll encounter similar monsters to the ones from the canals.
Kill Gavin the Thief
Continue exploring the aqueduct until you've located the Crucible. This object is being guarded by Gavin the Thief and killing him shouldn't be a problem, because he doesn't have a lot of life points and his attacks aren't that strong.
Pick up the Crucible
Pick up the Crucible after you've dealt with the boss. Covetous Shen wants a word with you and he'll tell you that he is a jeweler and from now he will be offering his services to you close to your personal chest in the Hidden Camp.
Go to the Ancient Path
Resume your journey and keep heading forward until you've located a passageway to the Ancient Path. Leah will leave you here and return to the Hidden Camp.
Get the Blood of Zoltun Kulle from the Cave of the Betrayer
Get the Blood of Zoltun Kulle from the Vault of the Assassin
The Ancient Path is a small location, however you will find a new waypoint here. Locate a passageway to the Desolate Sands. This area on the other hand is much bigger and you'll encounter various monsters here, including Lacuni Slashers, Lacuni Stalkers, Gore Harriers, Vile Swarms, Desert Hornets (they can deploy poisoned projectiles), Rockworms (they like to suddenly emerge from the ground) and plenty of others you're already familiar with.
Your current objective is to explore two areas. Start off by finding an entrance to Cave of the Betrayer Level 1.
You will be fighting monsters that you already know, however some of them may be more powerful and resistant to your attacks. Watch out for spiders and rockworms and focus on locating a passageway to Cave of the Betrayer Level 2.
The second level is a large area and you'll be dealing with the same creatures. Find Zoltun Kulle's blood, pick it up and return to the surface (Desolate Sands).
Another area you must find is the Vault of the Assassin. It doesn't have a typical entrance, because you must interact with a portal. Wait to be transported to a new location.
The vault is huge and it's filled with monsters. Don't forget about destroying Guardian Towers in order to prevent more hostiles from joining the battles. As for the monsters, aside from the skeletons and other common creatures you'll also encounter Blazing Guardians and their specialty is to throw fireballs.
You'll find Zoltun Kulle's blood probably somewhere on the edges of the map. Pick it up and return to the portal to end this quest.
