A bit more tricky than the other 3 star quest. Byakuren will give herself a 100% divine shield buff whenever she doesn't have it, so you need to either dispel it every turn or just carry weapons with exorcism. Murasa will summon anchors occasionally, which are field magic that do annoying things at end of turn like healing both themselves for 25% HP (which is 4250 for Byakuren and 7000 for Murasa), but she's vulnerable to berserk. Since you have one girl who will continuously try to buff herself and another who can be hit with Berserk, I figured that Reisen is the perfect character for this job, though in the end I forgot to actually set any axe skills to Aya so she couldn't help Reisen out on that.

![Labyrinth of Touhou 2 Steam - vs Diamond Knight
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.
