Ruan Mei Best Teams

March 7th (Imaginary) F2P Break

This free-to-play team involves Ruan Mei increasing everyone's DMG and Break Efficiency. March 7th will benefit from Ruan Mei's All-Type RES PEN and Break Effect buffs while the Trailblazer can provide Super Break DMG.

Firefly Break

Ruan Mei can benefit any unit who scales on the Break Effect stat. Characters like Firefly and the Fugue can benefit from Ruan Mei's Break Effect buffs. Ruan Mei can also delay an enemy's recovery from Weakness Break, which gives more chances to deal Super Break DMG to an enemy.

Kafka DoT

Ruan Mei is an outstanding Support for DoT teams as she can delay the enemies' recovery from Break, which lets the enemy take more DoTs before recovering to attack. Ruan Mei can also increase DoTs inflicted through Weakness Break and her Break Efficiency buff can help trigger more DoTs at a faster rate.

Castorice Toughness Break

Ruan Mei is excellent when paired with DPS characters whose attacks can dish out a huge amount of Toughness DMG. You can either slot in another Support for a stronger offense or a Preservation character to keep your party alive!

Dual DPS: Castorice & Mydei
