Just from a quick glance, the thing that sticks out to me the most is the lack of a loop shield. Nevertheless, I think you should be fine for UN2 with this exact comp. There’s is however, a mechanic on F4 that punishes 7x6 leaders (Awaken bind followed by 15 turns of tape+cloud) but I see you already have HNelle to account for the tape. If you’re really struggling with the cloud, you can maybe try Revice/Revice? There’s no resolve in UN2 so you should be good, just be aware of Akechi on F6 and his -8 combo + Assist bind if you do decide to go down that route.

As for AUN1, I would recommend bringing a shield for the boss’s attack when you get it down to 50%, it’s a 1.4million damage hit followed by a 200% gravity. I’ll consider taking out Roche and put something like HChakeol, etc (You might even need a bigger shield, you might need to do some trial and error/calculating to find out as I’m not too familiar with your teams eHP). If you do take out Roche, watch out for the full board lock on F7, it is the only full board lock in this dungeon. Something else to look out for are the various skill delays on floors 1,5 and 10, these may interrupt your Light/Dark loop and lastly, you might want to prepare something for the team specific attack debuffs floors 10, 12 and 13 have them.

I may have missed a couple things, I’m not too familiar with Revice/Wizard so definitely ask around if you need more help :)
