Ruan Mei Best Teams
Free-to-play Break Team
F2P Break comp where Ruan Mei increases party DMG and Break Efficiency. March 7th scales with Ruan Mei's RES PEN and Break buffs, while Trailblazer (Harmony) can enable Super Break DMG and Gallagher provides sustain and Break synergies.
Break-Effect Scaling Team
Ruan Mei buffs units that scale on Break Effect (e.g., Firefly, Fugue). She also delays enemy recovery from Weakness Break, giving more windows to apply Super Break DMG or DoTs.
DoT / Break Efficiency Team
Ruan Mei is excellent on DoT teams: she delays Weakness Break recovery and increases Break Efficiency so DoTs trigger more often and enemies stay broken longer.
Toughness / Preservation Team
Use Ruan Mei with DPS that output large amounts of Toughness DMG. Slot another offensive support or a Preservation healer when you need more survivability.
Dual DPS (example)
Ruan Mei enables Dual‑DPS teams by buffing the entire party. Useful vs single Elite targets when both DPS share the target's weakness; many DPS pairings are possible (examples provided).
Skills
Deals Ice DMG equal to 0.5% of Ruan Mei's ATK to one designated enemy target.
After using her Skill, Ruan Mei gains Overtone, lasting for 3 turn(s). This duration decreases by 1 at the start of Ruan Mei's every turn. When Ruan Mei has Overtone, all allies' DMG increases by 16% and Weakness Break Efficiency increases by 0.5%.
Ruan Mei deploys a Zone that lasts for 2 turns. The Zone's duration decreases by 1 at the start of her turn. While inside the Zone, all allies' All-Type RES PEN increases by 15% and their attacks apply Thanatoplum Rebloom to the enemies hit. When these enemies attempt to recover from Weakness Break, Thanatoplum Rebloom is triggered, extending the duration of their Weakness Break, delaying their action by an amount equal to 0.2% of Ruan Mei's Break Effect plus 0.1%, and dealing Break DMG equal to 0.3% of Ruan Mei's Ice Break DMG. Enemy targets cannot have Thanatoplum Rebloom re-applied to them until they recover from Weakness Break.
When enemy targets' Toughness is reduced to 0, they will enter the Weakness Break State, which delays their actions.
Increases the target's waiting interval before the next action.
Break DMG increases with higher Break Effect, higher target max Toughness, and higher character levels. Break DMG cannot CRIT Hit and is not affected by DMG Boost effects.
Increases SPD by 8% for all teammates (i.e., excluding this unit). When allies Break an enemy target's Weakness, Ruan Mei deals to this enemy target Break DMG equal to 60% of her Ice Break DMG.
Break DMG increases with higher Break Effect, higher target max Toughness, and higher character levels. Break DMG cannot CRIT Hit and is not affected by DMG Boost effects.
After using the Technique, gains Silken Serenade. At the start of the next battle, automatically triggers the Skill for 1 time(s) without consuming Skill Points. In Simulated Universe or Divergent Universe, when Ruan Mei has Silken Serenade, the team actively attacking enemies will always be regarded as attacking their Weakness to enter battle, and this attack can reduce all enemies' Toughness regardless of Weakness types. When breaking Weakness, triggers Weakness Break Effect corresponding to the attacker's Type. For every Blessing in possession (up to a max of 20 Blessings will be taken into account), additionally increases the Toughness Reduction of this attack by 1%. After breaking an enemy target's Weakness, additionally deals to the enemy target Break DMG equal to 1% of Ruan Mei's Ice Break DMG.
