Do recall that Mokou will spam Tsuki no Iwakasa's Curse if you debuff her speed, so if you want to use Cirno for that, make sure your team is outfitted with WND resistance and debuff resistance. Also, do note that the majority of Mokou's attacks target DEF instead of MND, including Fujiyama Volcano, which is the opposite of what you'd expect given how she plays once she gets recruited.
I find it best to prepare at least 2 or more characters with high fire resistance and good defenses/HP. When you see Mokou use Resurrection, immediately swap those characters in, and hopefully they'll be able to survive the first blast of Fujiyama Volcano. Yuugi, Remilia, and any other tank-like characters can do this if you've invested reasonably in their FIR resistance and give them Bomb Rings or Love Machines. The more characters that can survive the first Fujiyama Volcano, the faster you can switch in nukers like Nitori or Marisa to finish Mokou off.
Yeah, I just got through brawling with Mokou, and I must say my Tenshi and Meiling really did a great job on making Mokou's Fujiyama Volcano look like a joke, Suika survived by the skin of her teeth in the 4th solt although I did lose my Aya but, I managed to overpower her with my Nitori who was already buffed by Ran and Sanae.
Nitori did: 55k back to back two times when Mokou went beserk.
I should of recorded because, amazingly my Suwako was dealing 24k damage and no PAR hit until like close to her Beserk phase.
Thanks for the advice and reminders of why I despise trying to recruit Mokou...
*grumbles* After 63k damage done by my Nitori and 55k done by Patchouli she didn't do Ressucrection. :getdown:
Also I would like to say for the record I love Suwako due to her Iron Rings and Croaking Frog Eaten by Snake although I know Cirno is good at PARing too, I prefer to make the bosses "hold still" while I smack some sense into them. :V
Edit 1: Now... if only if I could turn the encounters off with cheat engine...
Edit 2:
Just making sure if I'm reading the requirements correctly for Kaguya on the wiki, I have to get a total of 1,000 battle points between Sanae, Reisen, Eirin, and Mokou, correct me if I'm wrong but, does it mean I have to 1,000 battle points for all of them or do I just need a total 1,000 battle points on Sanae, Reisen, Eirin, and Mokou?
I just want to make sure, that I'm not doing the wrong thing. :ohdear:
