The Great C (Labyrinth of Touhou 2 Steam)
Before anyone gets the wrong idea: no I did not beat the Great C at Challenge Level in 5 minutes, the footage has been sped up. If you want to see the full unedited version of this fight, here's the link: https://youtu.be/ceRPxI1rMmc
Anyway, this boss sucks. The boss' main gimmick is that you have to deal with and kill all 5 Cookies at the same time. If you don't kill them at the same time, the survivors will use their turn to make sure any empty slots get filled again and you don't want that since these bastards have about 3M HP. The concept of this fight isn't actually that bad on paper, but then 3peso went ahead and gave each Cookie the ability to use Black Universe whenever it feels like it, turning this fight into RNG garbage.
My strategy was as follows:
-Kill the original Cookie after it spawns the other Cookies. Despite how it looks, the original Cookie actually has LESS health than the ones it spawns. I don't like to fight around that middle cookie, so I just have Nitori remove it ASAP, and I REALLY HATE using Nitori, so that should say something about this boss. (Note: you can actually kill the Cookie before it spawns anything. Other people have done videos on that specific strategy)
-Inflict debuffs with Hina, SIL with Reisen and, most importantly, PSN with Mystia. I went with Mystia instead of Wriggle purely because of Instant Attack.
-Have Yuuka maintain the PSN effect with her Beauty of Nature move (which can increase the effect of existing ailments). While it's tempting to use Extra Attack, it's extremely risky because sometimes PSN doesn't proc, and it can be safer to use Flower Shot with Yuuka to even out the HP levels (and if you have Extra Attack on, you might accidentally kill the boss because the game decided that now is the best time to proc it 6 times in a row)
-When PSN eventually wears off, (try and) reapply it with Mystia. This is so much easier said than done. If you manage to do it, see teh step above.
-Get all the Cookies to low enough HP and finish off with Boosted Yuuka (or Nitori, in case Yuuka is dead at this point, which is very possible)
The strategy is very simple, but I cannot stress enough how RNG heavy this fight is. Even if you had the resources to max out a character's MND and DRK and MYS affinity, Black Universe (which reduces your HP to 1) and C Falling From the Sky (a piercing AOE unique to this boss) will finish off most characters anyway.
While I was able to make it out of this fight with a full party, that was just some insanely good luck. Like, I did not replay this fight until I got a win with a full party; this was my first win (and it was my only win, because you could not make me redo this fight at Challenge Level). I didn't even NOTICE that I'd got through this fight without casualties until I uploaded this video. This boss fight is nasty, and it's easily a contender for "worst designed boss in LOT2" IMO.
