Seems like Sparkle is E6S5 too. My E6S1 Acheron does around 2 Mil Damage with Fu Xuan - E0S1 Sparkle - E6 Pearls Pela. (I reach with Sparkle boost about 410 Crit Damage and 99,6 Crit Rate). Is Ruan Mei really THAT strong with Acheron or how do you reach those numbers?
Full team E6S5 and I’m using both Sparkle S5 for Ruan Mei/Sparkle so my Acheron reach 600 crit dmg with full buffs, and because crit dmg was too much it just not good anymore, in this case you want to buff other stat which is PEN RES and def down and Ruan Mei have all of them on her Kit
