Thread: Oni-Possessed Swordswoman Guide

I believe the silvers have the same chance of dropping on any stage so the best is low sortie costs that still have 2 silvers, but you also have to factor in what you need.

I'd say Chaos on the Frontline Chance for Giovanni and Elaine, as an added bonus you can get Demon Crystals there too. You also have a higher chance to get Momiji, but you already said you didn't care about her.
