How to Build Ruan Mei in HSR

Ruan Mei is a five-star support character who follows the Path of Harmony and has an Ice element. Her kit revolves around increasing the team’s Weakness Break Efficiency and delaying the action of Weakness Broken enemies.

• Light Cone: Past Self in Mirror
  • Alternative: Memories of the Past, Carve the Moon, Weave the Clouds, But the Battle Isn’t Over, Dance! Dance! Dance!, or Meshing Cogs
• Relics: Thief of Shooting Meteor
  • Body: HP% or DEF%
  • Feet: SPD
• Planar Ornaments: Penacony, Land of the Dreams
  • Planar Sphere: HP% or DEF%
  • Link Rope: Energy Regen Rate or Break Effect
• Eidolons: E1
• Trace Priority: Ultimate > Skill > Talent > Basic Attack

The best Light Cone for Ruan Mei is her signature Light Cone, Past Self in Mirror, which can increase her Break Effect by 60 percent. After unleashing her Ultimate, this item will also boost all allies’ DMG by 24 percent for three turns. Not only that but at the start of each wave, all party members will regenerate 10 Energy.

For Relic, you should equip the Thief of Shooting Meteor set on Ruan Mei to increase her Break Effect by 16 percent. When she inflicts Weakness Break on an enemy, she will also regenerate three Energy, allowing her to unleash her Ultimate faster.

You can equip the Penacony, Land of the Dreams set on Ruan Mei to get more Energy Regen Rate. This Planar Ornaments set is especially useful if you are running an Ice DPS, like Jingliu, since it provides a DMG buff for allies with the same element.

The best Eidolon to unlock is Ruan Mei’s E1, Neuronic Embroidery. When her Ultimate is in effect, the DMG dealt by all allies will ignore 20 percent of the target’s DEF, increasing your total damage output.

When upgrading her Traces, you should prioritize Ruan Mei’s Ultimate and Skill to maximize her buffs potential. Afterward, you can level up her Talent so you can boost her SPD buff and Ice Break DMG. I don’t really recommend upgrading her Basic Attack since she is meant to be a support unit.
