  • Basic Attack: Threading Fragrance (deals Ice damage equal to 50% of Ruan Mei's attack to a single enemy).
  • Skill: String Sings Slow Swirls (Ruan Mei gains Overtone, which lasts for three turns, and the duration of Overtone decreases by one at the start of each of her turns. When Overtone is active all allies' damage increases by 16% and Weakness Break Efficiency increases by 50%).
  • Ultimate: Petals to Stream, Repose in Dream (Ruan Mei deploys a field that lasts for two turns, with the duration of the field reducing by one at the start of each of her turns. While inside the field, all allies' All-Type Resistance Penetration increases by 15% and their attacks apply Thanatoplum Rebloom to the enemies hit. Thanatoplum Rebloom triggers when enemies attempt to recover from Weakness Break, extending the duration of their Weakness Break state and delaying their action by 20% of Ruan Mei's Break Effect plus 10%. Additionally, Thanatoplum Rebloom deals Break damage equal to 30% of Ruan Mei's Ice Break damage. Enemies can't have Thanatoplum Rebloom reapplied until they recover from Weakness Break).
  • Talent (passive ability): Somatotypical Helix (Increases the party's Speed by 8%, excluding Ruan Mei. When allies Break an enemy target's weakness, Ruan Mei deals Break Damage equal to 60% of her Ice Break Damage to the enemy that had Weakness Break applied).
  • Technique (overworld ability): Silken Serenade (Ruan Mei obtains Silken Serenade, which automatically triggers her Skill at the start of a battle. Triggering this effect with her Technique does not consume Skill Points. Additionally, when she has Silken Serenade active when attacking a target in the overworld of the Simulated Universe, the team's attacks in the Overworld is regarded as attacking enemies' Weaknesses, so it depletes Toughness regardless of Weakness types for all enemies. When inflicting Weakness Break in this way, a Break Effect is triggered corresponding to the Weakness Type of the attack. The Toughness Damage of this attack increases by 100% for every Blessing in possession, up to a maximum of 20 Blessings. At the same time, Break Damage is increased equal to 100% of Ruan Mei's Ice Break Damage).
  • Bonus Trace 1: Inert Respiration (Break Effect is increased by 20% for all allies).
  • Bonus Trace 2: Days Wane, Thoughts Wax (Ruan Mei regenerates five Energy at the start of her turn).
  • Bonus Trace 3: Candle Lights on Still Waters (In battle, for every 10% of Ruan Mei's Break Effect that exceeds 120%, her Skill additionally increases allies' damage by 6%, up to a maximum of 36%).
