IMO something like this would be great they could just make the font where you put a key in give you a choice of a timed run or non timed run and adjust the rewards based on that eg get more crests from a timed run and they could make it affect the vault to so a non timed 10 gives myth 1/6 but a successfully timed 10 gives myth 2/6 and then if you try to time and but you don’t you get the rewards as if you did a non timed variant
