Oh yeah, that reminds me...
I haven't modified my whaleship helper team for a long time. A lvl 100 Kerria should up the power a bit.
EDIT:
On a different note, that scene1 stage really takes a long time to clear.
I'm one/two fully ampied girls away from a full rainbow team and I still needed to juggle the squads a bit to get a good chance to clear the map.
