I have no cryo DPS, and her charged shot is ridiculously OP.
Well I have Qiqi, but I can't throw crit rate or crit damage as a main stat on her circlet.
Her burst - along with her charged shot (at level 2), also help apply cryo really easily for Klee to then go boom boom with melt.
She could also work super well with Venti's burst against large but bulky enemies, notably pyro slimes, which I really struggle against. As well as those stupid electro fatui, against who Qiqi is my only option if they put their shield on - and well, Qiqi's skill is not super good for that.
Finally, I don't know yet if I'm going with the Wanderer's Troupe set or the Blizzard Strayer set, but if I stick to Wanderer, I already have a decent enough set... The only problem is that at the moment, this is what is on my Jean while I farm for some more Viridescent Venerer artifacts (which is far from being my priority right now; my priority is getting the materials to up Ganyu as well as Klee's artifacts).
Basically this is what my level 70+ characters would be used as really
(right now Xiangling is my main DPS... maybe I'll keep her that way to be honest)
