(Blue Archive) Vol. 3 Ch 24, No Noa, Azusa, Iroha. Lvl 38.

Thanks to @jugglenaut1955, I could finally beat it (though it was very close).

This strategy is NOT patched, I just did it with this same team and strategy and cleared it fine (lvl 39). Some tips to know:
- Leave 3 Justina followers alive to prevent more from spawning, as soon as one dies, restart. That is the whole point of the strategy.
- It makes your life way easier if you upgrade Tsubaki's bag to T4, you can use your expert permits from the shop to get the materials. Once I did this, I cleared it immediately.
- I used Chinatsu instead of Hanae. Not really for any particular reason, I just happened to have Chinatsu more built and I cleared it.
Good luck c:

You don't know the absolute confusion i have when I thought we're supposed to lose

[BorisTheShashlikKing]

THANK YOU
I was pulling my hair out trying to beat the bastard. I tried your strat at a lower level but it just didn’t work. I levelled up to 39 and this strat works beautifully.
Thank you so much. I couldn’t have done it without your strat

[SeniorSteveeeeee]

thank you very much just finished the mission I'm jumping in joy rn

[Guinyus]

Holy shit it worked, thank you!
I can finally go back to reading the story

[bog]

Just finished the mission, the strat still works, thank you very much.

[obi-wankenobi]

THANK YOU! finally beat this damned level

[kaktusgoreng]

This actually works. Thanks!
I think the key is to place tsuvaki not too near Hiero. as She will attack the nearest Justina follower

[OuroborosTheInvincible]

I'm at my wits end, nothing I do works, it might be time to throw in the towel for this game.

[neckrokan]

as of may 5th 2024 it works! thank you so much dude!!

[SHADOWFRENZY]

Cheers, Tsubaki died right before the boss but this saved me a good amount of time.

[cwoofy]

TYSM SO MUCH BRO, i replaced yuuka and asuna with hanako (swimsuit) and azusa and i managed to beat the boss

[gordo]

Thanks, i love you it still works just took a few tries

I remember stumbling across this boss fight and i still get nightmares from it, i was so invested in the story and hit this wall, at the time i was level 43 and i used your units and lost about 10 times until i had a miracle, i used kotori's skill on the far left side of the area and it caused the whole unit to only focus on hieronymus while the smaller enemies were missing their shots so i ended up spamming both serina and hanae then serika and finally completed it with 3 seconds to spare, overall i hate it because unlike the end game you can borrow students from your friends, but with this one you're stuck with having to grind materials and level up for your unit even though the past fights gave you pre set units that were already over leveled beyond the recommended level.

(Sorry for the rant but this boss fight is infuriating)

[abejuelaallennahmarieo.]

Ohh myyy GOOOOD THAT WAS ALOT OF TRIAL AN ERROR.... I COMPLETED IT USING UR TEAM ...thanksss🎉🎉

Currently at lvl 42, with several attempts which result in failure. I will try again and again, using yours and many other guides to climb this seemingly insurmountable wall. At least this tells me it's not a wallet issue, but a skill issue. I can take comfort knowing improving is a matter of patience rather than income.

Did a little testing, and for anyone who can't get the Justinas to stop spawning, it works for me, but there appears to be more conditions to it than just leaving 3 of them alive. They consistently stop spawning for me as long as I stop damaging them completely before some point however, so if your tank is attacking the Justinas instead of Hieronymous, try moving the tank closer to Hiero so she attacks it instead.
(There is more stuff going on under the hood here though, so I'm unsure what the exact conditions actually are. I can leave 3 alive and it's enough, but if I leave 4 and kill the 4th one later, it'll spawn another wave. Similarly, I can do some random short damage to the Justinas using an EX for example, and as long as I don't kill them it's fine, so, I dunno. But leaving them alone early enough seems rather consistent so I'll leave it at that for my part.)

[truejohnsmith]

Thanks!
I changed Hanae with Fuuka and still worked!

[jayden-d]

Attempted to do it with a variation of this team (All level 39)
Serina (3*) Ayane (3*) Azusa (4*) Shiroko (5* + 1* Weapon and lvl 20 Affection) Tsubaki (2*) Yuuka (3*)
Tsubaki died almost instantly, but somehow my underbuilt Yuuka managed to survive for the entire run on her own. Shiroko and Azusa kept targetting the Justina followers, causing them to continuously respawn, but somehow my healing managed to keep Yuuka alive long enough for me to occasionally use Shiroko or Azusa's skill on the boss. Despite completely messing up the strategy I still managed to defeat the boss with Yuuka dying in the last 5 seconds. First try :D (I have no idea how that worked)
