Ruan Mei HSR 2.3 Skills Kit Guide

If you’re wondering why everyone’s hyped about Ruan Mei in Honkai Star Rail 2.3, let us break it down for you–her kit is straight-up cracked.

She’s basically what happens when Asta and Tingyun have a genius baby who also moonlights as the ultimate Weakness Break queen.

Basic Attack: Threading Fragrance

Ruan Mei’s Basic Attack is pretty simple.

She deals Ice Damage equal to 130% of her Attack to a single enemy. Nothing fancy here, but hey, free chip damage is free chip damage.

Skill: String Sings Slow Swirls

Now here’s where she starts flexing her Harmony powers. When Ruan Mei uses her Skill:

She gains Overtone for 3 turns.
While Overtone is active:
- All allies’ damage increases by 40%.
- Weakness Break Efficiency increases by 50%.

Ultimate: Petals to Stream, Repose in Dream

Ready for the real OP part?

Her Ultimate creates a field for 2 turns (based on her turns).
While this field is up:
- All allies gain +24% RES Penetration for every damage type.
- If an enemy gets Weakness Broken, their action is delayed by 15% + an extra 10%, AND they take an additional 180% of Ruan Mei’s Ice Break Damage.

Your enemies are frozen in place while your team beats them down mercilessly.

Talent: Somatotypical Helix

This Talent is freaking good:

Gives all allies (except herself) +11% Speed.
Whenever allies break an enemy’s weakness, the enemy takes extra damage equal to 150% of Ruan Mei’s Ice Break Damage.

That Speed buff alone can push your team’s cycle efficiency through the roof, letting you spam Skills and Ultimates like there’s no tomorrow.

Technique: Silken Serenade

Ruan Mei’s Technique is amazing for Simulated Universe runs or opening boss fights:

Activating it grants her Silken Serenade state.
Her Skill auto-triggers for 1 turn without using Skill Points at battle start.
In Simulated Universe, any attack from your team will count as hitting enemy weakness, making Weakness Breaks easier than ever. Also, you get massive toughness damage reduction based on the Blessings owned.

Ruan Mei’s Rotation

To keep her buffs flowing: kill → 2x Basic Attacks → repeat.

Drop her Ultimate right before you’re about to crack an enemy’s shield.

Honkai Star Rail 2.3 Ruan Mei Guide: Best Build

Alright, let’s kit her out properly, from relics, Light Cones, Planar Ornaments, and her best stats.

Best Light Cones for Ruan Mei

First things first, her Light Cone. Here are your top choices:

Past Self in Mirror (Signature)
- Grants 24% DMG bonus on Ultimate (meh for Break teams but decent overall).
- Teamwide Energy regen each wave + 1 Skill Point per Ultimate is huge for SP-hungry comps.
Memories of the Past (4-star)
- Adds Break Effect while giving extra Energy Regen, enabling smoother 3-turn Ultimate rotations.
Meshing Cogs (3-star)
- Generates Energy on each hit taken. Great budget option if you’re struggling with Ultimate uptime.
Dance! Dance! Dance!
- For teams needing extra action advances, especially if Ruan Mei can ult every 2-3 actions.

Best Relic Sets for Ruan Mei

Relic Set	Effect
4pc Thief of Shooting Meteor	Boosts Break Effect and regenerates Energy with every Weakness Break, her absolute BiS.
4pc Messenger Traversing Hackerspace	Gives your team +12% Speed, ideal if you’re aiming for tighter rotation cycles.

If you run Break Effect-focused teams (which you should with Ruan Mei), Thief of Shooting Meteor is a no-brainer.

But if you’re leaning more toward team Speed synergy, Messenger Traversing Hackerspace is also solid.

Best Planar Ornaments

Ornament Set	Effect
2pc Talia: Kingdom of Banditry	Increases Break Effect for even cooler Break Damage.
2pc Pan-Cosmic Commercial Enterprise	Boosts Effect Hit Rate and ATK, helping with consistency and a slight DPS bump.

Best Main Stats & Sub Stats

Here’s your stat priority cheat sheet:

Body: HP% or DEF%
Feet: Speed (always go Speed to reach key breakpoints)
Sphere: HP% or DEF%
Rope: Energy Regen Rate > Break Effect.

Sub Stats Priority: Break Effect (up to ~180%) > Speed (to hit breakpoints) > HP% = DEF% > Effect RES (aim for 30% with Broken Keel if needed).
