Above or below each frontier dungeon will be the quantity of keys we have in our stock. Tap the dungeon and it will ask if you want to use one key to unlock it. This is where our keys should be stored. NOT THE BOOK OF SOULS! Seems it should be an easy thing to do, really. They already have the graphics for each dungeon. Put 'em all on their own cosmos/time rift type of screen, transfer our key inventory their and tie them to their respective dungeon and be done with it. The problem with our keys overflowing our BOS inventory solved.
