i'm in your conscience
I MISSED IT OMG. That's one complaint I have about RSE. I feel like the Master Ball should be a major gift from someone important. Having it in a random room you could possibly miss is just...not nice. I understand that it was there for a reason, possibly for Maxie/Archie to use on their respective legendary, but maybe at least making that room a required room to go in would have helped. I think it's just more suited to be a gift, not something you find or don't find.
