Is there a way to see how many covenant items I have turned in?
I've found three different posts asking the same or at least a similar question as you:
- GameFAQs 1
- GameFAQs 2
The last link no one mentioned that its possible or not, but in the other two, they say that they haven't found a way to check. It seems like in Dark Souls 2 there wasn't a way either.
The only covenant you can keep track of your progress is the Blades of the Darkmoon. There's a roster item that you can use to see how many Proofs of Concord Kept you've turned in. There is no similar item for the other covenants.
