The enemies are very strong, and your decision-making has to be top-notch. You can find this quest in a book at the Blighted Village in the Whispering Depths.
This is the Search the Cellar guide:
- Search the Cellar Location
- To find the quest go to the Blighted Village at X: 25 Y:400.
- Interact with the well to go to the Whispering Depths.
- Once inside go to X: -496 Y: 366.

- Use the Dark Amethyst to unlock it, and finish your interaction.
There will be a boss of sorts in the Whispering Depths, you can choose to sneak here or defeat her. It’s the Phase Spider Matriarch and it gives you the Prisoner’s Robe if eliminated. If you choose to endure this quest, good luck!
