Thinking back to my platinum run for Birth By Sleep and remembered my proudest moment in gaming:
I'm pretty sure that somewhere on my laptop or wherever is a Proud Mode savefile I had of the PSP NA release with him beaten with Terra. (Mind you, this was pre-FM, so the rope attack was practically insta-death)
I don't think I'd ever have the patience to pull that off again.
Yeah, at least for bosses w/ EXP Zero. It doesn't affect regular mob fights, but Rhythm Mixer, D-Link finishers, Ignite Warp, etc. make that a non issue.
