Overview
Rosaria's burst creates a Cryo field and buffs party CRIT Rate based on her own CRIT Rate. Her skill teleports behind enemies for Cryo application. Build high CRIT Rate on Rosaria to share more with the team, aim for 100%+ CRIT Rate on Rosaria for maximum buff.
How to Play
Cast skill for Cryo application, burst for CRIT Rate buff and Cryo field. Swap off-field immediately, Rosaria's buff persists after swapping. Position skill behind enemies for backstab CRIT bonus. She works best in Physical and Freeze teams.
Optimal Rotation
Rosaria Skill, Rosaria Burst, Eula Skill/Burst, Eula on-field combo. In Freeze: Diona Shield, Rosaria Skill/Burst, Kazuha Swirl, Ayaka burst. Apply Rosaria buffs before DPS damage windows.
F2P Options
Dragonspine Spear or Favonius Lance work well. Rosaria is a 4★ from Mondstadt. C0 provides solid CRIT buffs, C6 Physical RES shred is excellent for Eula mains.
Common Mistakes
Building low CRIT Rate on Rosaria reduces the buff she shares. Using Rosaria skill from the front, backstab gives CRIT bonus. Keeping Rosaria on-field instead of swapping to DPS. Running Rosaria outside Cryo/Physical teams wastes her kit.
