Finally decided to head to Skellige.
I think I'm gonna progress a little bit with the main quest before deciding to explore Skellige and mess with side quests. I'm level 20 now so I'm gonna find an armorer that can craft for me the upgraded Feline armor and I'll roll with it.
Eh, switching from the alternate outfit to the default one would make more sense. I get that she's a sorceress, but Skellige seems really cold. Bare shoulders and exposed stocking are sexy and all, but if the Skellige winters are anything like those here in Canada, you want to at least cover the skin up.
