Finding keys and opening doors in No Rest for the Wicked is a bigger challenge in the game. Several locked doors block your path and as you progress through the main story, you may find yourself on the hunt for the Water Channel key.
How to Access No Rest for the Wicked Endgame Dungeon & Sewer Bug (Water Channel Key Not Dropping)
It’s a key that you have to find during the Black Trench quest and that will allow you to progress through the story. The problem with finding the Water Channel key is that it can take time in No Rest for the Wicked, and you can also find the key before you find the door. Luckily, we’ve seen both of these things make your life a lot easier.
The Water Channel Key you seek appears in The Black Trench Dungeon, dropping from an elite enemy you encounter at this location. This is part of a quest you can complete for Of Rats and Raiders in No Rest for the Wicked.
You must defeat the elite enemy to drop the Water Channel key, and then you can proceed through the rest of the dungeon. The Black Trench area is unlocked as you progress through the story, and requires you to defeat Darak in the Orban Glades and help Rattigan escape from his cell in Sacrament to reach the sewers. It’s best to check your stats before attempting these difficult tasks.
