Best Ruan Mei teams
Teams that want Ruan Mei
Quantum · Remembrance
Castorice
Castorice pays HP for her memosprite, so the line-up pairs a healer who profits from that with two Harmony units that raise the memosprite’s own damage.
Physical · Break
Boothill
A single-target Break carry: one Harmony unit raises Break damage, one implants the Weakness he needs, and the sustain is the one that also breaks.
Imaginary · Break
Rappa
Break damage across a whole wave rather than one target, so both Harmony slots go to Break amplification and the sustain adds Break of its own.
Fire · Erudition
Himeko • Nova
Her Talent hands every ally an Assist Skill that calls her Starblazer, so the other three slots are chosen for how often they take a turn.
Fire · Break
Firefly
Three Break supports and no sustain, trading safety for faster Weakness Break: Ruan Mei and The Dahlia raise Break efficiency, Fugue implants the Weakness. Run in 5.0% of clears across the four endgame modes in 4.6.
Physical · Erudition
Argenti
His 180-energy Ultimate is the whole kit, so every other slot is chosen for how much Energy it returns rather than how much damage it adds.
Fire · Break
Himeko
Himeko follows up whenever an enemy is Broken, which turns the standard-warp Erudition unit into a Break team’s damage dealer at no pull cost.
Physical · Break
Boothill
Three Break supports and no sustain for a single-target breaker: Fugue implants the Weakness, Ruan Mei and The Dahlia raise Break efficiency. Run in 0.1% of clears across the four endgame modes in 4.6.
Fire · Break
Himeko
Himeko gains Charge each time an enemy is Broken and follows up at full Charge, so three Break supports turn her Charge over faster. No sustain.
Ice · Destruction
Misha
Supports whose Skills cost Skill Points, each one a hit added to Misha’s next Ultimate: Bronya lets him act again, Ruan Mei buffs. Fu Xuan takes part of the damage for the team.
Physical · Break
Sushang
Sword Stance is guaranteed on a Weakness Broken target and her SPD rises whenever an enemy breaks, so the team breaks for her: Ruan Mei raises Break efficiency, Gallagher breaks and heals, Hanya returns Skill Points.
Quantum · Break
Xueyi
Her Ultimate ignores Weakness Type and hits up to 60% harder the more Toughness it removes. Ruan Mei raises Break efficiency, Bronya gives her another action, Fu Xuan takes part of the damage.
Physical · Destruction
Trailblazer (Destruction)
Bronya’s Skill gives the Trailblazer another action with 66% more DMG and Ruan Mei buffs; Luocha heals without needing a turn spent on it.
Ice · Destruction
Jingliu
Jingliu consumes allies’ HP when she attacks in Spectral Transmigration, so Huohuo’s healing carries the team. Sunday advances her and Ruan Mei buffs.
Lightning · Remembrance
Aglaea
A Remembrance carry whose memosprite takes the turns, with two Harmony units feeding it action advance and a healer covering the HP it costs.
Physical · Destruction
Phainon
A Destruction carry who wants raw multipliers rather than a mechanic, so the two support slots are whichever Harmony units buff hardest and the last is a healer.
Imaginary · HP scaling
Mydei
Mydei spends his own HP to attack, which turns a healer from a safety net into the thing that keeps the rotation running.
Ice · Remembrance
Evernight
Evernight and her memosprite both scale on Max HP and both pay HP to hit harder, so the healer is load-bearing and the buffs go to memosprite CRIT DMG.
Fire · Break
Firefly
Fugue implants the Weakness and The Dahlia’s Zone adds 50% Weakness Break Efficiency for the whole team. Lingsha heals and breaks. Run in 8.1% of clears across the four endgame modes in 4.6.
Lightning · Erudition
Jing Yuan
His Lightning-Lord attacks on its own turn and its damage scales with stacks, so the team is built to give him turns rather than multipliers.
Ice · Destruction
Jingliu
Jingliu drains her allies’ HP to enter her enhanced state, so the healer slot is not optional and the debuffer is there to cover her single-target ceiling.
Imaginary · Destruction
Dan Heng • Imbibitor Lunae
He spends three Skill Points on one enhanced Basic ATK, which means the other three slots have to generate Skill Points rather than consume them.
Wind · HP scaling
Blade
Blade needs to lose HP to hit hardest and needs to survive doing it, so the team carries both a healer and a shielder rather than a second buffer.
Quantum · Erudition
Qingque
A 4-star carry whose enhanced Basic ATK eats Skill Points and whose damage is a dice roll. It is the cheapest full team on this page, and the least consistent.
Physical · Break
Boothill
Fugue implants the Weakness and The Dahlia raises Break efficiency; Gallagher heals and his Besotted adds 12% Break DMG taken.
Quantum · Break
Xueyi
Xueyi gains Karma from every teammate’s Toughness damage and follows up at 8 stacks. The Harmony Trailblazer raises Break, Yukong’s Basic ATK doubles its Toughness Reduction, Gallagher heals.
Imaginary · Destruction
Dan Heng • Imbibitor Lunae
Yukong is an Imaginary Harmony unit whose Skill adds 80% ATK and whose Ultimate adds CRIT to all allies. Sparkle restores Skill Points, Luocha heals.
