In a row, no. In total, yes. I want to max out Clarte's shadow, all of the weapons, and at least 1 of each armor. Probably 2. So around 700 runs of the dungeon. And the point is to save time. A difference of 10 seconds in every run adds up to nearly 2 hours.
Tsubame AS has, by far, bar none, THE highest turn 1 DPS that I can see until Suzette's Awakened manifest comes out.
I don't have Melody, and even if I did she doubles up on Clarte and Tsubame doubles up on Strawboy so her nuke is only 800%.
I don't have Yukino either, so I can't even say whether her nuke is a nuke turn 1 or if it requires setup.
Ciel+Shannon AS can work together as turn 1 nukes that might have enough damage to kill the boss, but they require 3 debuffs to be set beforehand. That means either swapping Necoco to Morgana to Masukunda, and losing out on the crit buff, or getting lucky with Luna Cestus on Tsubame EVERY SINGLE RUN.
So no, I'm not going to be using anybody other than Tsubame to oneshot the boss, because she is the best character who can do so.
Felmina AS can oneshot all of the trash mobs with her priority move with the exception of Turis Gula, but with the Crafted Scratch and some Grasta shuffling I might be able to make her oneshot them as well.
If I still can't get her to oneshot everything then I'll try some normal attack setups, Myunfa AS treatises please start dropping
and if none of those work I guess I'll bite the bullet, get a Falcon grasta, and just have Tiramisu wipe everything with priority.
