Guide
How the kit works
If Yinlin enters with her Intro Skill, Raging Storm deals Electro DMG over a large area and applies Sinner's Mark. Hits from Zapstring's Dance and Thundering Wrath also apply the mark. The Liberation deals Electro DMG over a large area.
Cast Magnetic Roar to enter Execution Mode. Basic Attack hits and Dodge Counters can then trigger Electromagnetic Blast, which attacks every target with Sinner's Mark. You can trigger it up to four times. Use Resonance Skill again for Lightning Execution before switching or waiting too long, or it goes on cooldown.
These attacks build Judgment Points. At 100 points, Heavy Attack becomes Chameleon Cipher. Use it on marked enemies to replace Sinner's Mark with Punishment Mark for 18 seconds. When a marked enemy takes damage, Judgment Strike attacks all enemies with Punishment Mark. It deals Electro DMG as Resonance Skill DMG and can trigger once per second.
Switch to the next Resonator with Strategist when available. It amplifies their Electro DMG by 20% and Resonance Liberation DMG by 25% for 14 seconds, or until they switch out.
Build and why
Moonlit Clouds is the first set choice in the guide evidence. Its listed two-piece effect gives 10% Energy Regen. Empyrean Anthem is another option: the game recommends five pieces, and its listed two-piece effect also gives 10% Energy Regen. Void Thunder is a third choice, with 10% Electro DMG from two pieces. The supplied data does not describe the five-piece effects.
Stringmaster is the first weapon choice. It gives 12% Attribute DMG Bonus and gains ATK stacks from Resonance Skill DMG, which includes Judgment Strike. It also gives the wielder another 12% ATK while off the field.
Rime-Draped Sprouts ranks next. It gives ATK and can grant off-field Basic Attack DMG Bonus after its stacks are consumed by an Outro Skill. That bonus does not match Judgment Strike's Resonance Skill DMG type. Lethean Elegy follows, offering Resonance Skill DMG Bonus after Echo Skill DMG. Cosmic Ripples and Augment are other options if you have neither of those weapons.
Leveling priority
A suggested skill order is Chameleon Cipher, Magnetic Roar, then Thundering Wrath. The Forte covers Judgment Strike, while the Skill includes Magnetic Roar and Lightning Execution. Level Zapstring's Dance and Raging Storm afterward.
For maximum ascension, you need 170,000 Shell Credit, 4 LF Whisperin Core, 12 MF Whisperin Core, 12 HF Whisperin Core, 4 FF Whisperin Core, 46 Group Abomination Tacet Core and 60 Coriolus.
To max all skills, you need another 2,030,000 Shell Credit, 25 LF Whisperin Core, 28 MF Whisperin Core, 40 HF Whisperin Core, 57 FF Whisperin Core, 26 Dreamless Feather, 25 Lento Helix, 28 Adagio Helix, 55 Andante Helix and 67 Presto Helix.
Resonance Chain nodes worth it
For a suggested Resonance Chain priority, start with Ensnarled by Rapport (sequence 2). Each Electromagnetic Blast hit recovers 5 extra Judgment Points and 5 Resonance Energy. Unyielding Verdict (sequence 3) is another useful option: it increases Judgment Strike's DMG multiplier by 55%.
Morality's Crossroads (sequence 1) is worth considering for 70% more DMG on Magnetic Roar and Lightning Execution. Steadfast Conviction (sequence 4) gives the whole team 20% ATK for 12 seconds when Judgment Strike hits.
Resounding Will (sequence 5) adds 100% extra Thundering Wrath DMG against targets with either mark. Pursuit of Justice (sequence 6) lets Basic Attack hits trigger up to four Furious Thunder attacks within 30 seconds after the Liberation. Each deals Electro DMG equal to 419.59% of Yinlin's ATK and counts as Resonance Skill DMG. You can leave the later nodes aside if the earlier effects are what you want.
Teams
A teammate who deals Electro DMG can use the Electro amplification from Strategist. A character whose damage includes Resonance Liberation DMG can also use its other bonus. Xiangli Yao is an Electro teammate named in the guide evidence; Calcharo is another option.
Punishment Mark works with a teammate of any element: have that character damage marked enemies to trigger Judgment Strike. Jinhsi is a Spectro teammate named in the evidence, though the Electro DMG amplification does not increase Spectro DMG. Verina is another named teammate; choose the remaining slot around the support your team needs.
Common mistakes
Do not switch out with only Sinner's Mark on enemies: it disappears when Yinlin leaves the field. Fill Judgment Points and use Chameleon Cipher on marked targets first, so Punishment Mark can stay active for its duration.
Do not forget the second cast of Magnetic Roar. Lightning Execution gains 10% damage against targets with Sinner's Mark through Deadly Focus, which also gives Yinlin 10% ATK for 4 seconds when triggered.
Watch the outgoing switch too. Strategist (outro) ends early if its recipient switches out, so send in the character you want to benefit from it. When comparing sets, do not assume an unlisted five-piece effect from the two-piece bonus.
