Honestly this is a bit embarassing. I have beaten every single other record dungeon except this one, and I'm running into an issue with damage to Bandersnatch. I attempted a party with Braska and Montblanc who both have USBs and 450 mag. But since he's resisting everything their chain attacks are only doing 800 damage and it's an impossible fight as they'll run out of abilities. I did some research and there's very little reference to this battle, and it's been haunting me for months and I want it overwith, plus I can tell I must be missing something about magic parties. I've only been physical parties my entire play-time. May I request some assistance on how to understand the magic mechanics so I can assemble an appropriate team? It seems magic power and chain abilities alone just won't cut it.
