Back to the same well again - load up on cap up and let MC's autos go to work with Korwa 1. It's even better this time around since Beaks do stuff.
There's room for Leviathan here, as Elea is worth running, anyway; packing both debuffs and damage into one character slot is helpful and she even has a meter boost for cases where MC runs out. Packing that utility into one slot offers enough space to bring Nio, who otherwise might not bee along for the ride since she doesn't have much in the way of utility.
Bringing a bunch of damage and cap up doesn't leave room in the grid for HP. Not really something noticeable, though.
The first phase is probably the hardest; it takes a while to finish ramping Korwa. It helps that letting a Unisonic get off doesn't really matter; one of the three mirror image summon calls can block the whole ougi and 30 hits is trivial to clean immediately after.
MC's lack of meter to ougi with is a complication for 75-60%. Even while holding back, it's tough to refill the FC gauge before the second Karma trigger. It's much easier to eat the first one and cancel the second. DPTing even slower might have helped, as summonless expired one turn later than it should have, too late to not have to deal with an ougi. It's not a dealbreaker here, at least, as doing 36 hits with three echo buffs is trivial.
Doing 15m damage per turn off autos is perfectly doable like this. MC really hits hard, and it'd be swell if there were some proper supplemental for the grid. The second to last turn with Nio 4 added where MC autoed for around 25m damage was quite nice.
The one limitation is that Korwa's fil availability feels a bit short. I assume it's on account of MC, but maybe better play with Elea 2/Secret Triad or even using Elea 3 on her might have fixed things.
