Hello. Started the game upon release and played for about a month kind of started playing other things and stopped. I bought a whole bunch of medals when I started various 4 and 5*. How do I check if I have any good ones?

 

Thanks

Your most necessary medals will be stuff like Vivi, KH II Aerith, DiZ, Namine, KH II Kairi, Alice, or Pooh & Piglet. Less useful but still good are KH Aerith, Phil, and White Rabbit. After that, it's just a question of which medals are most efficient at dealing damage, but until you get very far in the game, even the farmable medals will be able to help you.
