6th stage cleared today.
Oh my god I had such a hellstorm of swears I wanted to unleash against Yuyuko & Youmu so badly.
Youmu was half the problem. Didn't help when she decided to use some manner of special attack and wipe random not Alice people. Damaging her was a slight issue too since only Patchy (at first) and Sakuya could inflict any decent amount of damage.
Then, Yuyuko....insta death shenanigans, RES debuff, regenerating like 50-100 HP at the end of every turn, and dodging like she was some kind of major DBZ villain. Need I say more?
...Oh yeah, her final screw you move. Real LOVELY kick in the pants that is.
Failed like 4-5 times (Including Yuyuko hax death killing Alice like one round before she would have used her final attack and me falling to said final attack the next turn).
Spoiler'ing my strategy changeup for those that want to figure out this fight on their own...and because it's words words and more words.
Spoiler:
After that, strategy change. Put Marisa into the party in place of Patchy since she had cheap and effective single target fire attacks to abuse.
This is where my strategy started to come together. Alice would hopefully soak up most of Youmu's attacks, Sakuya just attacked with a dagger (Reassigned her skill points so she could maximize a dagger's usefulness), and Sanae buffed/healed.
Byakuren and Marisa were absolutely critical to this approach working correctly. Byakuren buffed herself with Hyper Trigger, then hit Youmu with Unresist on her next turn, then Starfire spam after that. Starfire didn't have a problem debuffing her MDEF, that's for sure.
Marisa spammed Hellfire on Youmu for ~350-400 dmg and slowly rising from there on.
Once Youmu fell, Byakuren Unresist'd Yuyuko, then smacked her with Starfire to debuff her MDEF. This is where the MDEF buff makes a difference. Even when I was using Patchy's Summer Flare on failed attempts, it turned it from a paltry 15-20 dmg, if that, to a whopping 400 or so damage.
For Marisa on my last couple of attempts, this turned her into a machine of destruction. Passion Blaze could easily do 800-900 dmg to Yuyuko if she had a MATK buff.
From here, I just needed Alice to spam London Dolls to protect someone once the final attack triggered. Wouldn't take long for that to happen with the damage Marisa was doing after debuffing her MDEF, that's for sure.
In case of emergency, Mokou as my Commander could revive a random singular downed character 3 times.
On my winning attempt, Youmu never used some manner of spellcard to own half my party for once....thank god.
Yuyuko didn't take too long to bring down afterwards.
Final attack...Sakuya survived it as I was planning to have happen...and oh what Sanae survived too how did that happen? Whatever, I'll take it.
7th stage is opened, final party member acquired. I think I have an idea who my 7th stage boss will be...I think :ohdear:.
