My thoughts/story on fighting Eientei for the third time:
Funny... thing to mention... last year and I wanted to keep quiet about this but, I somehow bypassed Kaguya's nuke phase on my 3rd playthrough of LoT due to Suwako getting a PAR off on Kaguya, after I killed Eirin during the Eientei fight, which saved me when I killed Eirin with a strategy I call "HELP ME Eirin" which involves poisoning/paring Reisen then poisoning Erin. Then proceeded to pepper Eirin, Kaguya, and Reisen with nukes but, here's the thing don't use poison on Kaguya just keep hitting her with single targeting or nukes spells until you feel she's gonna go down along with Eirin THEN poison her but, keep Reisen locked with Suwako's PAR or anyone who can Par and reapply the poison too if it wears off as long as you can although a few hits on them helps too but, don't kill Reisen during the commotion. Also, love the fact that Tenshi and Meiling were tanking while it gave me time to pull out Ran to buff anyone or have Sanae to come in and buff/heal along with Reimu, while sometimes Aya or Sakuya used their speed buffs. Yuugi, Patchouli, and Nitori go to town on Kaguya.
I had Komachi in reserve to just let her soak in the buffs my Ran was throwing out until Kaguya was gone, which was during my first and second playthroughs I usually knockout Kaguya but, on my third playthrough... I was shocked I took out Eirin with my idea. Then I used my buffed up Yuugi to Knockout Kaguya who used focus which was during I think by the time Erin healed Reisen for the who knows how many time, but, it didn't help so I used Suwako's Iron Rings to stop Kaguya which managed to land PAR status on her by some miracle, then switched her with Yuugi to use Irremoveable Shackles, but it wasn't enough even though Eirin died after healing who had Kaguya took damage from my nukes and poisons so, fearing for the worse I tried to prepare myself but, then a miracle happened she used Swallow's Cowrie Shell instead of Hourai Barrage.
My comment was "HOLY CRAP it's a miracle!" which gave me a chance to switch in Patchouli who already was buffed and finished her off with Silent Selene, from then on I just had to deal with near death experiences from Reisen's attacks and her Mind Stormie which made my Komachi so, happy that I just killed Reisen with Scythe that Chooses Death.
TLDR version: "Sometimes, it's good to balance out your party with the essential stuff if you want to kill annoyances. Namely the Eientei crew although I love them to death... THEY ARE ANNOYING TO FIGHT." :V
I just felt like telling my story, of managing to do something achievable although maybe some people already did it too. :ohdear:
