Kind of a stupid fight, really. The Wandering Sin she drops on turn 1 can be kind of nasty, and Spirit Decomposition is an automatic kill unless your slot 1 tank has 200 DTH resist, but her other "normal" attacks aren't that interesting. Then at 90% she will concentrate for Last Judgement, which doesn't just empty her ATB but also switches up her stats; sending her DEF/MND through the roofs while tanking her SPD, so you can barely hurt her (unless you have Kaguya) and are forced to sit through an eternity until she finishes charging her big nasty nuke to.... kill one character. She'll then proceed to do that several more time as her HP drops from any retaliatory attacks (her DEF/MND drops down again after Last Judgement), and the whole thing ends up feeling like a series of DBZ episodes. Oh well, at least it's not even remotely challenging as a fight.

Im not gonna make a video of every single [character]s Shadow - Abyss fights because they generally arent that interesting and except for the first few, Ill be steamrollering through most of them with level advantage to keep up long streaks. I will make videos for the unique bosses in Infinity Corridor, though.
Diamond Knight is the first unique boss in IC and shows up at 30F. It has a few physical attacks to throw around but except for the first turn, most of the time it just opts to toss a Scourge for overkill damage. If it has a debuff itll do an auto ATK buff as well; this doesnt take up a turn but DOES count as a turn so if it uses that on turn 1 it will probably throw a scourge right afterwards, at which point you mostly dont care about the ATK buff any more because its not going to make Scourge kill its target any deader. So I just tossed a SPD debuff at it and went on a damage race; it has really high defenses but low HP and vulnerable to SIL/HVY, and is weak to NTR or MYS, so a universally usable way to deal with this thing is to inflict HVY and use Iron Mountain Charge on it. Since I have Alice with her 40% defense ignore though, tossing SIL and using Hourai Doll seemed much more effective.
