Here is the normal behavior of the “A Strange Key” quest:
- Player gets the “strange key” as a random drop from cultists or from Direni.
- Player uses it to enter the Depraved Sanctuary.
- Upon entering, player gets exp and the quest completes.
However, if you a have a strange key from a previous difficulty in your inventory, you are able to enter the Depraved Sanctuary without triggering the quest nor the quest reward.
I had a strange key from Elite, which I didn’t use, then I entered the Depraved Sanctuary on Ultimate and didn’t get exp. A little bit further, two keys dropped from enemies inside the sanctuary and upon picking one up, I got the quest completion immediately.
Very very minor bug, but I just found it very amusing to have keys drop when I was already inside the dungeon. ![]()
