Ruan Mei GUIDE

Understand Ruan Mei

Useful when…

  • Increase allied damage and Toughness reduction while Overtone is active.
  • Increase teammate SPD and deal Ice Break damage when allies break Weakness.
  • Extend Weakness Break and delay enemies through Thanatoplum Rebloom.

Skill, SPD, and Break effects

Using String Sings Slow Swirls grants Overtone for three turns, with duration reduced at the start of Ruan Mei's turns. At the listed level-one values, Overtone increases all allies' damage by 16% and Weakness Break Efficiency by 50%. Her Talent increases SPD by 8% for teammates other than Ruan Mei and deals Ice Break damage when allies break an enemy's Weakness. These percentages are level-one values. [hsr-1303:ability:1; hsr-1303:ability:3]

Ultimate field and Rebloom

Her Ultimate creates a Zone lasting two turns, with duration reduced at the start of her turns. While it is active, allies gain All-Type RES PEN and their attacks apply Thanatoplum Rebloom to enemies hit. When an affected enemy attempts to recover from Weakness Break, Rebloom triggers, extends the Break, delays the enemy based on Ruan Mei's Break Effect plus a flat value, and deals Ice Break damage. The listed level-one All-Type RES PEN is 15%. Rebloom cannot be reapplied to that enemy until it recovers from Weakness Break. [hsr-1303:ability:2]

Technique and trace tracks

Her Technique grants Silken Serenade, which automatically triggers her Skill once at the start of the next battle without consuming Skill Points. In Simulated Universe or Divergent Universe, while Silken Serenade is active, the team can reduce Toughness regardless of Weakness Type when actively attacking enemies; the attack's Toughness reduction increases with Blessings up to the listed cap. Her listed trace tracks include Skill, Ultimate, Talent, and Break, SPD, and DEF bonus traces. [hsr-1303:ability:5; hsr-1303:upgrades]

Duration and conditions

Overtone and the Ultimate Zone lose duration at the start of Ruan Mei's turns. Thanatoplum Rebloom triggers when an affected enemy attempts to recover from Weakness Break, and cannot be reapplied before that enemy recovers. The Technique's Weakness-independent Toughness reduction is specified for Simulated Universe or Divergent Universe. [hsr-1303:ability:1; hsr-1303:ability:2; hsr-1303:ability:5]

Limitations and tradeoffs

  • Overtone and the Ultimate Zone lose duration at the start of Ruan Mei's turns.
  • Thanatoplum Rebloom requires an enemy to attempt recovery from Weakness Break before it triggers.

Common mistakes to avoid

  • Treating listed level-one percentages as fixed at every trace level.
  • Assuming Thanatoplum Rebloom triggers immediately on every Weakness Break.
  • Applying the Technique's Weakness-independent Toughness reduction outside Simulated Universe or Divergent Universe.
