This is my clorinde team:

c6 chev 4pc NO
C6 fischl 4 pc GT
c0 clorinde 4 pc whimsy
C0 mavuika 4pc obsidian

Should I keep mavuika or get durin? Is the Hex buff really worth it? Or should I just get her signature. She is currently C0 right now using R4 finale of the deep. with all buffs she has around a 69/165 CV 3,200 atk.
