Ruan Mei Best Teams

Free-to-play Break Team

A free-to-play Break-focused comp where Ruan Mei increases party DMG, Break Efficiency and All‑Type RES PEN. March 7th is the Break DPS, the Trailblazer (Harmony) can enable Super Break DMG, and Gallagher provides Break-scaling sustain.

Break Effect Team (Firefly & Fugue)

Ruan Mei maximizes the value of Break-scales on allies like Firefly and Fugue by increasing Break Effect and delaying recovery from Weakness Break, creating more windows for Super Break and DoT interactions.

DoT / Break Efficiency Team (Kafka)

A DoT-centric comp where Ruan Mei's Break Efficiency and Break-delay let DoT units like Kafka and Hysilens apply more damage over time and trigger effects more reliably.

Toughness / Preservation Team (Castorice)

Works best with DPS that deal high Toughness DMG. Ruan Mei amplifies their effect with Break Efficiency and Break Effect buffs; slot preservation or additional support depending on content difficulty.

Dual DPS Example (Castorice + Mydei)

Example dual-DPS composition demonstrating Ruan Mei's ability to buff two DPS simultaneously. Useful vs elites or content where both DPS share weaknesses or toughness windows.

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 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%.
