Got a whole bunch done in today's session. Went from the start of stage 4 to finishing stage 6 just a little while ago.
Stage 4 bosses...jokes as I was predicting. Royal Flare + Fantasy Heaven alone took off close to 2000 HP from Okuu. Next attack on her took her down. This all occured on the first turn BTW.
Orin got whacked by tons of water magic and some light magic and fell on round #2 of the fight with ease.
Stage 5 boss...eh, pushover. Two rounds into the fight and the boss was down ~95% HP or so. She switched to water phase, but yeah, only 5% HP or so left doesn't mean you get to pull off your cheapo super heal (which would have been blocked by Sakuya's Killing World if it somehow got that far).
Stage 6 bosses...Byakuren didn't even get a chance to stick a Starfire onto Yuyuko.
Round #1 of the fight...Alice uses Hourai Doll to draw as many attacks as possible, Nitori uses Elemental Shells to enchant her gun with fire, Marisa spikes Youmu in the face with Hellfire, Patchouli uses Hot Spot Vulcan to boost fire damage, and Byakuren uses Hyper Trigger on herself as part 1 of the Starfire strat setup. Youmu sets up Asura Stance while Yuyu does nothing special worth noting.
Round #2...Marionette Peril to protect Marisa and Patchy, Nitori uses Purgatory Impale, Marisa uses Passion Blaze, Patchy uses Active Elemental to manipulate the land for fire, and Byakuren sticks an Unresist on Yuyuko for part 2 of the Starfire setup.
However...something amusing happened here. Peril, Active Elemental, Passion Blaze, and Unresist went off first. Youmu just did a normal attack, Yuyu tried a Curse on Alice which missed.
Nitori fired off Purgatory Impale, scoring a slayer effect on Youmu due to her weapon...and because it was a line attack, it also hit Yuyuko.
The kicker? It hit them both for close to 2000 damage
. Youmu went down hard and Yuyu lost more than half her HP in that one attack.
Round #3...Nitori fires off her Flame Chaser, Alice uses London Doll on Byakuren to prep for Resurrection Butterfly, Marisa casts Hellfire, Patchy casts Fire Crest, and Byakuren casts Starfire on Yuyu. Also, I used Mokou's Phoenix Rebirth commander spell to be doubly safe just incase Yuyu got a lucky instant death spell through.
That never happened. Sure Marisa and Patchy's moves went off first before Starfire, meaning they did no damage...but they did trigger Nitori's chaser, letting her do ~800-850 damage a hit. The 2nd triggering of her chaser dropped Yuyu...and oh dear apparently Yuyu can't fire off her final attack if she's defeated by a chaser.
I really don't want to know what would have happened if Nitori had a Weapon Bless casted on her :ohdear:.
EDIT: Okay, I was curious so I decided to pull out a backup save file before the stage 6 bosses, maxed out Byakuren's Support Magic tree, then did the same motions in Round #1 as before, except that Byakuren placed a Weapon Bless on Nitori right away.
Next turn...Nitori launched her Purgatory Impale. After Hot Spot Vulcan for a Fire Power field effect + Active Elemental to shift the land heavily in fire's favor...

.
It could go even higher I bet with a formation that boosted physical damage and/or fire effects (Formation used in that pic and my winning attempt before that was Magician's Circle). 4k+ on Yuyuko? Perhaps so if that happened.
