I've been able to win as Ryoma. It's not difficult, but random crits and the two retainer's poison skills helped out a lot. I went and took out Camilla first, not that big of an issue. Then camped and waited for Elise, Sakura, Takumi, and Leo. Kagero got taken out at some point. ( Odin's BS vengeance ) from there, Hinoka and Xander weren't too much of an issue. I baited out Setsuna and then took out Hinoka. Azama attacked but didn't kill. Then it was easy pickings with Xander. Took out Peri first ( sting shuriken ) and then Xander, and finally Laslow. I guess a bit of luck is required, but it wasn't too bad. I'll try others tonight. Good luck everyone! I need these items for my lunatic classic run ( accidentally deleted my file when I was on chapter 20 of revelation grinding supports ugh )
