Lust Sin slowed down wins.

It actually works with Ragna and Noel also, but I feel like they don't really need it. Nu is difficult to pull off as it is, and having the above combo for her works well.

If anyone still cares about CT, I've been practicing a haida-loop against Nu which does just over 5000 damage... 3C, 22BBC, 66C, 22B, 22C, 66C, 22C, 66C, 22C, 66C, jc, j.C, 236C = ~5k The timing is a bit weird. If you are right next to Nu as you start the combo, do a 22BBC to get her a good distance away from you. If you are a bit far away, either don't 22B at all, or only press B once so she goes a bit further. The 22B afterward just has to hit Nu so she can stay on the ground, and follow up with a 22C. When you 66C, make sure she is somewhat near the ground, and then 22C. For the last part, 66C as soon as possible and 22C right after so you can 66C her in the remainder of the combo. The most I've been able to do was about 5,138 damage, I think. It's weird at first, but the timing is easy once you get it down. Because online Nus love backdashing, a well guessed 3C can bring their health down by about 70%. Once again though, unless you completely master it, it's not exactly a good idea to always go for it, as you'll most likely drop the combo. Still, bring a Nu down like that is always satisfying.
