Acheron is rated S+ on MoC and A on Pure Fiction (According to Prydwen)

I like how theirs 4 cold and 1 innocent

she's a solid unit for moc I can say the best unit a f2p can have even without lightcone she's just massive yeah and I agree with pf positioning there are other characters in the future that'll help to solidify her place in S maybe for PF

is that with or without signature lightcone?

I was actually expecting her to be lower tier because it sounded like she needed investment into e2, s1, or new event nihility characters to really get going.
