I ended up feeding spare Iris to CC Iris for a CR. That will make a difference on a few maps plus take pressure off me deploying her so fast when farming gold/plat armors.

Still no healers dropped this event so can't CC Dorca yet.

I'm still in two minds whether to attempt to CR Calliope yet or not. Is there anything past War and Magic that is worth it?

I am tempted to roll the gacha (I have 5 SC - I spent the rest trying to get Jerome last week) and hope I get something better that can help but I think I'd be better off using it either to farm Phalanx 2 or power level when close enough to next level for it to matter. Or I could stop being so silly and impulsive and save up to 50.

I think overall in my case a lot of it is just be patient and keep grinding, hoping the gaps will end up filling themselves. I'm in no rush to beat Base Scramble II even if it does increase my resource farming efficiency.
