I am posting links to youtube videos for guides that I have used for myself to help me get through these. Please go over these so you have an idea how to do these fights as some of these are really hard to learn.

Thanks for sharing the videos, I never played a Final Fantasy game before, but I saw all the Final Fantasy movies. My most favorite is the Final Fantasy VII: Advent Children, it is a sequel to Final Fantasy VII. Maybe one day I will download and play one of the Final Fantasy game on my PC, but that's only before I finish my gacha life online and prodigy from cool math games. I really like these games and I don't want to play other game until I finish these.
