For those who might have issues with this quest and can't complete it for some reason.
I had to go to the Fungal Folly and equip the relic and then I could get the quest done by pressing the quest in the tracker.
Not speaking with Brann.It could work if you press the quest in the tracker at any point but for me it didn't work like that.
I tried so many times but for some reason it bugged out.
i had to walk back into the delve and then it gave me objective credit to turn in on the spot. nothing i did outside the delve worked. dont drop the quest. just try walking into a delve.
