Overview

How to Play
Use Skill to deploy Overtone at the start of combat. Overtone increases all allies' Break Effect by 50%+. Use Ultimate before your Break DPS enters their burst window. Keep Overtone active at all times — refresh with Skill when it expires.
Optimal Rotation
Ruan Mei Skill (Overtone) → Ruan Mei Ultimate (team buff) → Firefly enters Sam → Break weakness for Super Break → refresh Overtone → repeat. Ruan Mei should act before your Break DPS every cycle.
