Decided to experiment with AirServer + OBS Studio and record the entire encounter. Bahamut wasn’t nearly as bad as U+ Cagnazzo (…in which I pretty much ran out of every single ability and barely scraped by with a mastery). Having literally zero Final Fantasy III synergy hurts though.
Roaming Warrior: Lenna (Princess’ Favor)
Notable Soul Breaks: Blade Beam, Air Strike, Shout, Tailwind, Sentinel’s Grimoire, Dreamstage
Two re-dos of this fight were required: The first because I had forgotten to swap out Thundaga Strike with Aerora Strike and the second because I had forgotten to equip Power Breakdown. Aside from that, it was a straightforward encounter. Bahamut hits pretty hard with both physical as well as magical damage even with full mitigation up, but it is manageable as long as you recast Wall/Shellga/etc before it completely drops off. The first half of the fight is physical AoE damage for the most part. I couldn’t fit Protectga into my party configuration but Power Breakdown mitigated enough of the damage to make it survivable. Dreamstage + Air Strike during the second half of the fight = MVP.
I probably should have equipped a damage RM over Ace Striker on Cloud since Aerora Strike was hitting pretty high with Shout, but not at the damage cap. Also, I ended up accidentally fat finger casting Tailwind instead of Shout about half-way through the fight, which cut my damage by quite a bit :3.
