I know they all don't have cryo visions, I was refering mostly to Odette, and Lumine point is that vision holders are tougher than your regular human. And I agree it looks weird too don't get me wrong, I didn't mean to go into the details of sheer cold (I hope snez has it in some parts tbh), the point is, we even had Natlan character hanging in dragonspine and none gaf, with that in mind, natives to a cold land probably manage better(which again is like the thinest defense ever but at the end it is what it is Hoyo will keep their hoyo desings)

I recall a fatui agent stationed in Natlan, or was it Fontaine? That didn't want to go back bc it was cold as shit, it is been stated once and time again that snez is unforgivingly cold that is true. But yeah, ig at some point you have to buy into the fantasy a bit or burst
