Jesus Christ. The floor 145 (I think it is?) boss is hard. I've fought them a good 4 times now and can't come up with a way to beat them. Hmmm.
Maybe I should level up so I can get better Persona. Not that that matters, because they nullify your Zio immunity. Maybe I should charm them or something so they can't nullify my immunity. The heat wave attack isn't so bad, it's the goddamn thunder attacks that make the battle hard, because they buff up their magic attacks before using them. I guess the whole thunder immunity thing wouldn't matter if I had a Persona or party member who had Dekunda...
Anyways, I tried the 5 Persona fusion...DAISOUJOU!

I can't make him yet because I'm not level 53 but...awesome!
