The Stained Soil locations quest is the first thing that truly stumped me in Midnight Suns. It’s not exactly an Easter Egg hunt: you’re looking for evidence of the remains of witches killed by Hiram Shaw, the cruel Reverend of Salem in the Marvel universe.

Had I unlocked enough of the Abbey locations to be able to locate the Stained Soil samples? Did I need to complete the Standing Stones puzzle? Midnight Suns doesn’t give a ton of direction.

The good news: if you’re struggling with it, there’s no hurry to complete the quest. The Abbey stuff, for the most part, runs independently from the campaign, and I was able to do a bunch of story missions even though I hadn’t made progress on finding the Stained Soil. If you need help, though, here’s a step-by-step walkthrough.
