KH2FM FFVII - vs Challenge Mode Sephiroth (before TWTNW)

In this mod, many bosses and enemies have altered AI as a feature tied to the Challenge Mode ability. Sephiroth's AI behavior and attacks have been changed pretty drastically, even having totally new attacks and being able to cancel certain actions into others where he previously couldn't. He's about on par with the difficulty of the game's other superbosses now, whereas before he was noticeably weaker.

This fight was done on LV41 Critical Mode / Challenge Mode, before the fight with Roxas in TWTNW. Challenge Mode is an ability in this mod that allows for unlimited use of the drive gauge at the cost of heavily reduced damage done to enemies, and cannot be turned off once enabled.
