Water Fat is one of the most intense and strategic quests on Dune: Awakening. It is part of Assassin’s Handbook quest chain, and this quest focuses on stealth, political assassination, and manipulation. You will have to sneak into a water shipper’s residence, poison his water tank, and sneak back unnoticed during this mission.

Starting the Water Fat Mission

To unlock this mission, you must complete the previous contracts in the Assassin’s Handbook series. After that, the task becomes available automatically. To begin, speak with the character Elara Tuek, who will give you instructions and the target's coordinates. After a short cutscene, she will explain the mission details.

You’ll need an ornithopter to reach the operation site — the water shipper’s estate, located south of Arrakeen. Travel is done via the Overland Map.

The estate is a large, well-fortified fortress with heavy security. Snipers patrol the rooftops and can spot you from afar. Patrol soldiers constantly move around the premises, and massive scanner reflectors control the entire area. These will automatically detect suspicious activity and trigger an alarm if you’re discovered. Once that happens, all guards go into combat mode and actively pursue the intruder.

This makes the mission extremely difficult — any mistake can ruin your plan. Choosing a safe route and syncing your movement with patrol cycles is essential.

Meeting Yargun and Choosing a Path

Key information for completing the mission comes from an NPC named Yargun. He can be found on a platform between the paths of two reflectors, out in the open. However, you can’t approach him immediately — the area is guarded by two patrolling enemies. You must eliminate them with long-range weapons before stepping out of cover.

After neutralizing the guards and speaking to Yargun, the player learns there are two ways to infiltrate the estate:

• Through the underground tunnel – A hidden cave that leads beneath the fortress. This is the safer option but requires a detour. The recommended route is to the left of Yargun’s platform, through the poppy fields, to the Underground Passage entrance.
• Through the upper level of the fortress – A risky option that involves direct combat, dodging additional scanners, and shooting guards. This route is dangerous and less reliable for stealth-based playthroughs.

Infiltrating the Estate

If you choose the underground path, stick to the shadows, avoid patrols, and use stealth abilities. Once you emerge on the fortress grounds, it’s best to circle around the building on the right, avoiding spotlights and sensors.

Use abilities like Bindu Sprint to move quickly through narrow gaps between scanners.

Poisoning the Water

After infiltrating the building, turn left — the water reservoir is located there. Interact with the object and use the poison to contaminate the water.

Once the task is done, choose your escape route — through the cave or another exit. Spotlights, snipers, and scanners remain active until the end of the mission, so move fast and avoid detection. Once you reach your ornithopter, take off — and the mission will be completed upon returning to base.
