Thanks guys for the tips. Guess I will pick one of my rainbows for the maxing - feeding 100 ampies x3 times (HP/ATK/DEF) - god dam, how many golds this gonna cost? LOL, okay I will do it. Either Lycoris Shrine Maiden, Victoria June Bride, or Ionocidium. Feels like I need to flip a 3-sided coin...

I just got 300 delicious rainbow coins so...I dunno. I don't have a rainbow counter girl yet. I was doing those ultimate missions lately, thus why the question, I can do up to maybe ~650-700k on those depending on RNG luck, but struggle on anything higher. Was thinking of Dusty Christmas ver. for 1st turn 1.65x, crit. pwnage ownage, but Safforn now looking not bad too, she is truly all purpose. And I will keep Phoenix chan in mind, I def. want her, but probably not 'till much later in the future.
