So I'm on new game plus and I'm trying to get my compendium/collection of personas to 100% because I'm a completionist. Does anyone have any tips for fusing personas/how not to waste all your money on buying them so you can fuse more personas. I also don't want to fill my stock with personas I'll likely never use. Any advice is appreciated, also if anyone knows fun things to do on a second play-through/things I should do on a second play-through that would help.
