So after many hours of grinding, Katie, Bashira, Cloris, Bernice, and Iris are finally at 50CC30. My other units are in the 30-40 range w/o CC (except for my lv. 25 Olivie) and Prince is at lv. 85. At this point, I'm not sure whether to spend a bit more of my SCs, considering I have 40/70 that I bought yesterday left. And I want to continue the Treacherous Pirate missions. Any ideas? I might spend a bit more SCs level Leeanne up 50 and CC her if needed.

Also, how does Cuterie and Monica's drop rate boost passives work? Do I just need them in my team or do they need to be on the field for it to work?
