Just what the title says, motherfucker.
In no order:
FFT: Velius. IMO, there’s just no way to prepare for this fight. It’s just a matter of happening to position your team just right and hope to god he doesn’t cast Cyclops more than once. I’ve played through the game 3 times, and each time I was stuck on this fight for a good week or two. Elmdor is second, only because trying to steal the Genji assortment from him is nigh impossible.
FFIV: Zeromus. I remember the guide calling for a certain recommended level, I ended up being a good 10 levels or so past it, to the point where Rosa was going just before him, so I managed to stay healed, and even then I just barely squeaked by. I must’ve played the game off and on grinding levels for 6 months or so before I finally managed to beat him.
Breath of Fire III: Teepo Dragon Form. I don’t remember why, but I had a tough time with this one. Also, when those two horse dudes get together into megahorse, I was stuck on that one for a while as well.
Xenogears: Metatron? It’s been a long time, but I think he had a fuel draining skill or something.
Lost Odyssey: The first two fucking boss fights in the game. It shows a complete difficulty imbalance when the first two boss fights in the game are way harder than the last one. I was stuck on the Bogomoray for several days.
MGS3: The Boss. If I had the snow camo and I could figure out the CQC (never did figure it out lol) it may have been easier, but it took about 3 hours before I managed to stun her to “death.” Runner up: The bee guy.
MGS: The Hin-D
MGS4: Raging Raven. I was stuck on this for a good few days too.
Heh, a lot of these have been so long, I don’t remember the details. My memory sucks.
