How the kit works
Start with Basic Attack: Penultimate. Repeatedly press during its third hit to keep striking; stop pressing to move to the fourth hit. A long enough sequence enhances that fourth hit. You can dodge during the third hit without interrupting the combo count.
Electric DMG from skills builds Flash Connect Voltage. At 75%, Flash Connect becomes active. Voltage above that threshold increases the Damage and Daze of Basic Attack: Enchanted Moonlit Blossoms by 1% and 0.5% respectively for each extra 1% consumed. The attack consumes all Voltage and does not build it itself.
Hold the Basic Attack button in Flash Connect for up to five rush attacks followed by a Finishing Move. Release early if you need to finish sooner. The rushes reduce damage received by 40%, while the Finishing Move grants invulnerability. Triggering it just before an attack produces a Perfect Dodge.
Core Passive: Eternal Seasons gives the Finishing Move five stacks of Subjugation, plus one per rush attack. Each stack raises the target's Stun DMG Multiplier by 4%, up to 20 stacks. Normal and elite enemies receive double stacks; stacks reset when the target recovers from Stun.
Use EX Special Attack: Moonlit Begonia (Special) when you have enough Energy. It grants invulnerability and lets you go straight into the third Basic Attack hit afterward. Chain Attack: Tranquil Serenade deals 3% more skill DMG per Subjugation stack on the target.
Build and why
Use four pieces of King of the Summit for a team-oriented build. Its two-piece effect increases attack Daze by 6%. As a Stun character, Qingyi can trigger the four-piece effect with an EX Special Attack or Chain Attack, giving the squad 15% CRIT DMG for 15 seconds. At 50% CRIT Rate or more, it grants another 15%.
Four pieces of Shockstar Disco focus on Qingyi's Daze. The set gives 6% Impact and makes Basic Attacks, Dash Attacks and Dodge Counters inflict 20% more Daze to their main target. Pair either four-piece set with two pieces of Thunder Metal for 10% Electric DMG; two pieces of Shockstar Disco also fit alongside King of the Summit.
Choose CRIT Rate on disc 4, Electric DMG Bonus or Percent ATK on disc 5, and Impact on disc 6. Look for CRIT Rate and Percent ATK in substats. Impact supports her Stun role and her Additional Ability converts Impact above 120 into ATK, up to its limit.
Ice-Jade Teapot is the first weapon choice. Basic Attack hits build Impact stacks, and acquiring a stack at 15 or more gives the squad 20% DMG for 10 seconds. The Restrained is next: its stacks increase Basic Attack DMG and Daze. Hellfire Gears is another option, increasing Impact after an EX Special Attack and Energy Regen while Qingyi is off-field.
Leveling priority
Follow the game's order: Core Passive: Eternal Seasons first, then Basic Attack: Penultimate, Special Attack: Sunlit Glory, Chain Attack: Tranquil Serenade, Quick Assist: Wind Through the Pines, and Dodge: Swan Song. The passive controls Subjugation, while Basic Attacks are central to building and spending Voltage.
For maximum ascension, you need 800,000 Denny, 4 Basic Stun Certification Seal, 32 Advanced Stun Certification Seal and 30 Buster Certification Seal.
For all skills, you need 2,905,000 Denny, 25 Basic Shock Chip, 75 Advanced Shock Chip, 250 Specialized Shock Chip, 5 Hamster Cage Pass, 9 Living Drive and 60 Higher Dimensional Data: Ethereal Pursuit.
Mindscapes worth it
Minimal Effort, Maximum Impact is worth considering for stronger Stun windows. Each Subjugation stack raises the Stun DMG Multiplier by 135% of its original value, and Qingyi deals 15% more Daze to a target once her applied stacks reach the maximum.
Insulation Breakdown gives her maximum Voltage on entering combat and increases its accumulation rate by 30%. At maximum Voltage, Basic Attack: Enchanted Moonlit Blossoms reduces a hit enemy's DEF by 15% and increases Qingyi's CRIT Rate against it by 20% for 15 seconds.
Eight Meridians is another upgrade to consider: it gives that Basic Attack 100% more CRIT DMG and reduces the target's Attribute DMG RES by 20% for 15 seconds. Drink Hot Water and Youthful Spirit raise skill levels, while Stable Arc Barrier adds a shield and conditional Energy. You can skip those if you are satisfied with the base kit.
Teams
An Attack teammate activates Additional Ability: Three Verses of Farewell at Yang Pass: Qingyi's Basic Attacks deal 20% more Daze. For every point of Impact above 120, she also gains 6 ATK, up to 600. A teammate from her faction activates it too.
For the remaining slot, consider a Support such as Electric Rina or Ether Astra Yao. Qingyi's Defensive Assist: Graceful Embellishment can parry an incoming attack and deal Daze when you bring her in.
Common mistakes
Do not hold the Basic Attack button expecting Basic Attack: Enchanted Moonlit Blossoms before reaching 75% Voltage. Watch the gauge, and remember that spending Voltage above 75% increases the move's Damage and Daze.
Do not release the rush sequence early every time. Each rush adds a Subjugation stack to the Finishing Move, though an early release can help you respond to an attack. The 40% damage reduction during the rush is not invulnerability.
Do not forget the squad condition for Additional Ability: Three Verses of Farewell at Yang Pass. Without an Attack teammate or a teammate from Qingyi's faction, you miss its Basic Attack Daze bonus and Impact-to-ATK effect.
