i suggest a simple check box for the mystery box chests when doing the new streaking feature for solo dungeons that way if u have keys u can use them for chests if not or don't want to spend them u can turn it off to keep it fair make a bonus cost for using it and/or extra time taken and u still miss the tomb's and monster hideouts so there's still reason to do the dungeons manually

just a simple idea that might help a lot ty fr your time
