I have Linnea C0 and I am building her with my Noelle C4. I will pull Colombina and would like to C6 Noelle. In the meantime what are my 2 best last slots? I have C1 Aino, C2 Xingqiu, and C5 Illuga.
Mona is my only other viable hydro but she is on my Mualani team. I also have C1 Kachina but I am assuming she is worse than my other options.
Thank you!
