Platinum already and I'm still in the third dungeon... and I'm liking it a lot.
Also... I just got one of those "special" personae that live inside chests. Are they useful for something?
As Shouta said they are useful for fusions, and one of them is (I think) mandatory for the coop that ask for specific persona creation.
I though I was screwed when failed to capture one, but you can also find them in mementos. Not in chests, but directly as a still diamond-shaped shadow.
