So, there’s a delve quest to use the Unbreakable Iron Idol, giving this ability to Brann, I couldn’t complete the quest so I abandoned it. However, when I re-entered a Delve, it caused the item to show up in my bag as “Already Known” and I can’t delete it, it’s just there, taking up bag space. I put it in my bank.
Anyways, hope that’s detailed enough.
- this seems to have been resolved, happy delving!
