I'm exploring Teyvat for a different reason now 

Nice, I just got c6 Lynette too (was going for at least c4 on Arlecchino's banner). I use her as a sub-dps on my Wanderer team usually. I like how she distracts the enemies with her taunt so I don't need to use a shielder with Wanderer. The rotations on that team are pretty long too, so the 12 second double skill isn't too bad.

SPOILERS FOR THE FONTAINE ARCHON QUEST About Lynette: Presumably, while their mother was pregnant with them, she imagined they were cat people with the calico gene shenanigans where the traits are more likely show up on the women than the men. So then the Oceanid babies inside her took on that form. Lynette was technically a water spirit in the shape of a human catgirl, and now after Neuvillette's whole thing, she's ACTUALLY a human catgirl. But still a legitimate twin of Lyney. Who knows what this future shall hold for them.

What about TF Lynette to maximize normal uptime for the funzies?

I LOVE LYNETTE I JUST CANT PRIORITIZE HER CONS RN😭😭 but i get to live my dream through you babe
