Completed using Noa, Valentines Aglovale, Cagliostro, Io, and backline Halluel&Malluel. Noa getting knocked out is intentional. Tormentor unnecessary. Expand to read more.
Surprisingly, I haven't seen anyone else upload this Io cannon method or at least found it from searching terms relevant to the raid and character names. It's quite effective and works even in pubs if you end up having to carry the raid.
Grand Cagliostro's Pinnacle of Geometry is a cute and funny skill that lets you completely stop everything in the game including Gopherwood Ark which would otherwise devastate this human nuke setup. With this skill - and also being a skill that you can refresh with Kirin - you can just cheese all the end game bosses with the Io light skill damage setup.
Aglovale is essentially required for this, making it rather inaccessible to most players. On top of being able to fire off five skills in one turn, his nuke damage and debuffs are significant for this raid.
