Luize. Because this was my first attempt, there was dialogue before preparations, so I skipped all that. Equip-wise, they weren't too different from Sara's fight. If you hit her with an element, she will counter with a buff that resist that element. If you multi-hit with elements, she'll repeatedly cast that buff in hopes to resist it more, but worry not! They don't stack. Dispel is handy for resetting those buffs. More reflect lols.
Sara. She has two field spells; one which I didn't look too into picks an element, and at the end of that turn she will use an AoE of that element while the other is just Jammer. Reflect is lol. Before this expansion came out, I did a lot of grinding. Even then I'm still missing Yukkuri Sisters and Yukkuri King shikigamis.
Pardon my platform failing and other random failing. Thankfully I got used to the other stages along the way. Figuring out how to dodge each of Nue's attack took a while too. Accidently adapting to new methods of dodging and such~ The music in this game is so good!
Monochrome Suika. If you can beat her before the boss of this stage, I recommend it. Beating her after the boss like I did makes the reward kind of pointless for this trial. I missed a spellcard and super rank block in stage 3, near the end in fact. Also there are 3 hidden pieces to a badge, one in each stage. Give them to Alice and you'll get Quick Switch that lets you swap partners without wasting your turn!
Big Suika.Took me quite some tries, but I finally beat her upon returning to town and restocking as well as getting some more cards. Relying on Menrui's F.U.V. just turns my survival luck based. And previous attempts I had trouble maintaining the 3 spirit cost whenever Suika decides to drain my spirit with her chain. I countered that with 4 Grimoires and gives me extra spirit to deal more damage with as well!
Spectre. I tried this after clearing stage 2, so I got some extra stuff like Damage Dodge and 3-card spell counter.The more small spectres you leave alive when it merges, the stronger and bigger it is!
