How the kit works
Start with Obedience of Rules when available. It puts Changli in True Sight for 12 seconds. Use Basic Attack: True Sight - Charge (skill) in the air or Basic Attack: True Sight - Conquest (skill) on the ground. Each ends True Sight and grants one Enflamement stack on hit. Both attacks count as Resonance Skill DMG.
Tripartite Flames also puts Changli in True Sight after a dash. It has two charges, with one restored every 12 seconds, and can be used in the air. Another route is the fourth ground or mid-air attack of Blazing Enlightment.
At four Enflamement stacks, use Heavy Attack: Flaming Sacrifice. It consumes the stacks, deals Fusion DMG counted as Resonance Skill DMG and reduces damage Changli takes during the cast by 40%. Radiance of Fealty deals Fusion DMG and gives her four stacks. Follow it with Flaming Sacrifice within 10 seconds to get the 25% ATK increase from Fiery Feather.
Secret Strategist gives the True Sight attacks 5% Fusion DMG Bonus per Enflamement stack. Sweeping Force gives 20% Fusion DMG Bonus and ignores 15% of the target's DEF when casting Flaming Sacrifice or Radiance of Fealty.
Build and why
Use the recommended five-piece Molten Rift set. Its listed two-piece effect gives 10% Fusion DMG, which suits Changli's attacks. Moonlit Clouds and Lingering Tunes are alternatives to consider: their two-piece effects give 10% Energy Regen and 10% ATK respectively. No five-piece effects for these sets are listed here.
Blazing Brilliance is the first weapon choice. It gives 12% ATK, and its Searing Feather stacks give 4% Resonance Skill DMG Bonus each, up to 14 stacks. Casting Resonance Skill grants five stacks. That bonus fits both the True Sight attacks and Flaming Sacrifice.
Emerald of Genesis comes next: it gives 12.8% Energy Regen and grants 6% ATK per Resonance Skill cast, up to two stacks for 10 seconds. Red Spring is another option, with 12% ATK and Basic Attack DMG bonuses. Keep in mind that Changli's True Sight attacks are counted as Resonance Skill DMG despite their Basic Attack names.
For stats, consider Fusion DMG Bonus and ATK because her kit deals Fusion DMG and Fiery Feather increases ATK. Crit. Rate and Energy Regen are also options to consider. The supplied build does not specify stat targets.
Leveling priority
A good leveling order is Flaming Sacrifice, Tripartite Flames, Radiance of Fealty, Blazing Enlightment, then Obedience of Rules. Flaming Sacrifice uses the stacks her other attacks build, while Tripartite Flames gives access to the True Sight attacks. This order is a suggestion; no game-provided skill order is listed.
For maximum ascension, collect 170,000 Shell Credit, 4 Crude Ring, 12 Basic Ring, 12 Improved Ring, 4 Tailored Ring, 46 Rage Tacet Core and 60 Pavo Plum.
To raise all skills to the maximum, the listed materials are 2,030,000 Shell Credit, 25 Crude Ring, 28 Basic Ring, 40 Improved Ring, 57 Tailored Ring, 26 Sentinel's Dagger, 25 Inert Metallic Drip, 28 Reactive Metallic Drip, 55 Polarized Metallic Drip and 67 Heterized Metallic Drip. These are separate from the ascension materials.
Resonance Chain nodes worth it
For the biggest upgrades, consider Realized Plans (sequence 6) first. It makes Tripartite Flames, Flaming Sacrifice and Radiance of Fealty ignore another 40% of the target's DEF. Sacrificed Gains (sequence 5) is another major option: it raises Flaming Sacrifice's multiplier by 50% and its damage dealt by 50%.
Pursuit of Desires (sequence 2) is worth considering for its 25% Crit. Rate increase from Enflamement, lasting eight seconds. Hidden Thoughts (sequence 1) gives Tripartite Flames and Flaming Sacrifice 10% more damage dealt and resistance to interruption.
If you stop at sequence 2, you can leave Learned Secrets (sequence 3) and Polished Words (sequence 4) for later. The former increases Radiance of Fealty damage by 80%; the latter gives the team 20% ATK for 30 seconds after Changli's Intro Skill. Neither is needed to use her base stack and True Sight mechanics.
Teams
Strategy of Duality gives the incoming Resonator 20% Fusion DMG Amplification and 25% Resonance Liberation DMG Amplification for 10 seconds, or until that Resonator switches out. Bring in the teammate you want to benefit from it and give them time to use the effect.
Brant, Lupa and Encore are Fusion teammates named in the guide evidence, so they are options to try with Changli. For a third slot, consider Verina or Shorekeeper, who are also named as teammates. Check the other characters' abilities when deciding how to divide field time; their kits are not listed here.
Common mistakes
Do not leave True Sight unused: it lasts 12 seconds and ends after the relevant attack. Make sure that attack hits if you want its Enflamement stack. Watch the two charges of Tripartite Flames, rather than expecting both to return at once.
Avoid using Radiance of Fealty while already sitting on four Enflamement stacks when you can spend them first. After the Liberation, use Flaming Sacrifice within the Fiery Feather window. Also remember that switching out the recipient of Strategy of Duality ends its amplification before the 10 seconds are up.
