Rosaria is a 4-star Cryo Polearm user from Mondstadt in Genshin Impact. She is a sister of the Church of Favonius who rarely participates in church activities and protects the city from the shadows. As a quick-swap sub-DPS or support, she excels at off-field Cryo application with her Elemental Skill, Ravaging Confession, which dashes behind enemies, and her Elemental Burst for burst damage and CRIT Rate boost to teammates. Her passive increases party movement speed at night. Though not the most devout nun, she vigilantly safeguards Mondstadt.
