Think I'm near the end of Persona 3 FES myself (just the main part; I've no plans to dive into "The Answer" straight away). It's become a little tedious, and I've started playing it between other games, but now I feel compelled to wrap it up.
[quote name='jello44']I'm wondering if this has happened to anyone else who has played Digital Devil Saga 2.
Alright, so I'm on the last boss, the very last part of him, nearly

ing dead. He did what is probably his "ultimate" move. While this is happening, all this garbled text appeared on the top part of the screen and afterwards, total party wipe. I was pretty pissed off because it was the second time it happened during the same battle, but it didn't nearly do as much damage the first time. I'm 99% positive that I had all buffs/debuffs off, so I don't think that was it.
Needless to say, I'm pretty miffed, nearly done with this

ing game, especially after all the frustration of the previous

ing boss, who seemed to be harder than the final boss.[/QUOTE]
That final boss took me a few attempts-- not nearly as many as the previous boss you mentioned. I think I ended up going back to grind for one of my characters to get Debilitate; I didn't have it at the time, and it was really useful for DDS1's final boss.
