Library Of Ruina

So, first and foremost, this battle is near impossible to complete on Xbox. I believe I attempted over 25 times and it crashed every time. I eventually found a laptop that ran the game like molasses, but it didn't crash. So I would strongly recommend doing this battle on Windows (as the game is play anywhere thank gouda)

As such, I needed a strat that was painfully reliable so I could do it 25 times. And a kind human on Reddit posted one, to which I repost here in the hopes it helps you. Also, I'm kind of writing this on memory, so it won't be 1000% word precise.

Round One: Binah's team. Binah has +3 slash power, 2 from bamboo kim, 1 from the regular source. The other 4 are all rabbits with all ranged pages of 1 & 2 cost and the "first turn you get +" power stat boosts along with the Ranged Attack +1 you get from the jester early on. Your goal round one is to shoot Philip very very dead. The remainder of your time is used to shoot Greta to death. If you succeed in killing them both and have anything left, just sit back and get murdered.

Round Two: Geburah's team, Geburah is the Red Mist with Myo's Pro, Lone Fixer, and HP/stagger gain from the sweepers. The other 4 I had as the 3 Udjat's and Nikolai, and I used the "When emotions go up, gain 15 or 20% stagger or hp" add-ons and the original reverberation protection of 1-2 damage along w/Boris's Grit. The ancillary librarians are just stuffed with bad cards that clash a lot, as your goal is to lose as many clashes as possible. We're doing the climb to mountain of corpses for Geburah. Her deck is basically 2x each of the 2 drops she has access to, 2 Knuckles (the 2 drop that has a counter card & draws) and one of Focus cards that raises her strength by 3 next scene. On your last emotion, choose the one that makes you immune to stagger damage. That's functionally the whole ballgame. Kill the puppeteer first in Act 2 and kill Pluto first in Act 3 and make sure you block Tanya's "you can't heal" move.

This worked about 9-10 times in a row in between crashes, so it feels really solid. I was running on a series X so your attempts on a One or Series S may go smoother? That wouldn't make any sense, but what does these days.

Just wanted to throw up a solution as a warning that this fight crashes a lot. It uses a lot of animations that overload the game. I had to redo this fight 3 times before it didn’t crash. It supposedly works better on Windows but I didn’t try.

I’m not great at writing out strategies but basically I used Myongest Geb with sayos 2 draw passive on 3 characters, lots of health/mind maulers, and some of the new page passives. Once I found the right combination this fight was a cinch for Gebs floor… but it took some tinkering as usual. Don’t give up and keep playing around. All phases the enemies power up immensely through the fight and you’re objective is to solo out the deadliest enemies before it gets too late, as well as providing damage control as best as possible to stop the enemies from buffing up too much, or providing too many status effects.

There’s a claws of savagery stealth strat that’s supposedly perma invincibility but I didn’t play around with it because I didn’t have the Now Die card. If you’re interested:
There’s also a solo Gebura video using this strategy that explains it better. Anyways here’s what I did

I recommend for the first phase Tanking and killing Phillip before he uses mass attack while light regen clashing Bremens buffs. U need to kill Phillip ASAP. My order was Phillip - Bremen - Eileen - Greta. Once Geb is powered up she slashed these guys into oblivion. Make sure to cancel Gretas 11-15 dice whenever she uses it as that destroys the rest of her dice attacks on that die.

Phase 2 I prioritize Tanya as she gets a massive buff if she’s last alive. Use the strings from the puppet on Tanyas beat down. I used the puppets ~30 attack to take care of my second Red String character. This phase is very easy.

If you reach phase 3 without crashing I would kill Pluto first. He spawns an add otherwise and they’re all deadly so I just chose to get rid of him first as Argalia is impossible to kill until last. The next character (Elena I think?) is deadly. She killed most of my team and I barely got through with Gebs floor but remember there’s 5 floors. Try to finish most of phase 3 with Gebura but either way you’ll probably have enough backup to take care of things
