Something I'm not too sure of, what are the shops used for in this game? In OFA and imas 2, you would visit them and buy outfits and accessories but it seems like in this game you get them in present drops instead. Or can you still buy outfits from the shop? I'm just sort of confused since I go to choose it and three different icons show up in a new screen and I have no idea what I'm supposed to do.
The shop is actually a tailor, sort of. The first icon lets you upgrade outfits and accessories you own with duplicates. It's alright, if you have multiples of the same item, but I've found that in many cases it's better to use over-ranked outfits and accessories anyway, even if they do take your Appeal down because they'll probably still end up increasing it by quite a bit, plus you can use the abilities they add that you may not have on other, appropriately-ranked clothing. Just be careful if you do upgrade that you don't use your better items as the material instead of the base, I don't know if it adds what has already been added to your better one to the worse one that you may accidentally use as the base.
The second icon is where you exchange five at a time per exchange of Gold, Silver, or Bronze Cards, which you earn from lives as Clear/EX Clear rewards or random drops, and an amount of money relative to the type of card for a random outfit or an accessory(I think?).
And the third icon is where you buy some types of enhancements, I guess. I'm not really familiar with them since I never bothered to try them. I'm sure they have their uses though. Seems one affects normal beats you make while using a burst, maybe it increases the points you get from them. I'm sure they're along the lines of that.
