Maotd: Yeah guess you're right. I usually rely on broken dodge mechanics to win, but with 5 turn limit, I always draw and then time runs out. That's amazing your gold/rainbow team can get the job done in 5 turns, I really underestimated counters. I don't have enough members atm to build decent team, maybe in near future. At this point, I'm just happy that rewards are random.

wbread: If girl's personal earrings, then you need the crystal things in pic below, do aqua stages to collect them.

You need 9 white crystals for rainbow upgrade. Can't remember amount needed for gold, maybe 9...? Not sure
