Liyue's star opera singer is a Normal Attack buffer. Her Burst grants the whole party the Flying Cloud Flag Formation, which adds damage based on her DEF to a limited number of Normal Attack hits. A niche support today, she still helps fast-hitting Normal Attack carries such as Clorinde, Noelle or Arlecchino.

Raise her to level 90: her buff scales on DEF, and base DEF is one of the few ways to get more of it. Use the press Skill (2 particles) rather than the hold version.

Teams

Recommended teams

Clorinde with Yun Jin

One of KQM's recommended setups: Clorinde's many fast hits use every Flag Formation stack, Fischl adds off-field Electro and Xilonen shreds RES.

Noelle Geo

Great in multi-target: Noelle's wide swings trigger the buff on every enemy, Gorou adds DEF and Furina DMG%.

Arlecchino with Yun Jin

Four elements for the full passive; Yelan enables Vaporize and Bennett buffs ATK.

Guide

How to play

How she works

  • Cliffbreaker's Banner (Burst, 60 Energy) deals AoE Geo DMG and gives every party member the Flying Cloud Flag Formation: their Normal Attack hits deal extra DMG based on Yun Jin's current DEF, for 12s or a limited number of hits (each enemy hit uses one).
  • Breaking Conventions raises that bonus by a further 2.5/5/7.5/11.5% of her DEF with 1/2/3/4 Elemental Types in the party: four-element teams get the most out of her.
  • Opening Flourish (Skill): press for a quick Geo hit and 2 particles, or hold to charge while shielded. True to Oneself unleashes the Level 2 charge instantly if she is hit at the right moment.

Rotation

  1. E (press), then Q.
  2. Swap to your Normal Attack carry and hit as fast as possible before the Flag Formation stacks run out.

Her buff is flat damage per hit, so it is worth the most on carries with many small Normal Attack hits.

Strengths

  • Flat Normal Attack DMG buff for the whole party
  • Works with any element, best in four-element teams
  • Short field time and cheap 4-star constellations
  • Her hold Skill doubles as a shield and a counter

Weaknesses

  • Limited number of buffed hits: weak with slow or few-hit carries
  • Very high Energy needs as the only Geo unit
  • Niche in the 7.1 meta (T4 on Prydwen, B on Game8)
  • Scales on DEF, which is hard to stack
