Ever since her appearance in Genshin Impact Dragonspine, Rosaria has been quite popular in the community. Both Dragonspine and her cold persona are well-suited for her Cryo Vision. The Sister's dark past is likely the reason for this demeanor, where as a child, Rosaria was trained by bandits, people who use her to steal and deceive. Later on, this skill comes in handy when Varka allows Rosaria to redeem herself.
