How the kit works
Start with Tinkling Jade when available. It deals Glacio DMG, applies Glacio Chafe and sends Suisui into Drizzle Stance. If you start in Zephyr Stance instead, use Unraveled Spring and Vernal Screen to build Cloud Breath. At the maximum of 120, Vernal Screen becomes Awakening Spring. Cast it to enter Drizzle Stance and apply Glacio Chafe.
In Drizzle Stance, Lambent Gold lets attacks build Floral Epistle, up to 600. The fourth Basic Attack applies Glacio Chafe. A successful Parting Mist dodge restores 102 Floral Epistle, and casting the Drizzle Stance Skill while Suisui is active restores 100. The stance ends after 15 seconds and clears the resource.
Cast Song of Thoroughfare to deploy Ceaseless Landscape for 30 seconds, then switch with Rippling Waters. The Outro gives the team 25% All DMG Amplification for 30 seconds. If the field is active, Suisui enters Roaming Transcendent and performs Plume Steps according to the Floral Epistle spent. Each step heals nearby active teammates in the field, grants interruption resistance and applies Glacio Chafe.
Build and why
Song of Feathered Trace is the first set to consider: its two-piece bonus gives 10% Energy Regen, which suits Suisui's Outro scaling. Moonlit Clouds has the same listed two-piece bonus. A five-piece Rejuvenating Glow setup is another option; its listed two-piece bonus gives 10% Healing Bonus. The five-piece effects are not provided here, so compare these options with that limit in mind.
Firstlight's Herald is the top weapon choice. It gives 12% Max HP and restores 8 Concerto Energy when Suisui casts her Liberation, once every 20 seconds. Applying Glacio Chafe and healing while she is on field can activate its 20% team ATK bonus; her next Outro can grant both weapon effects for 6 seconds.
Stellar Symphony is another option with 12% HP and the same Liberation-based Concerto Energy restoration. Its team ATK bonus requires a Resonance Skill that heals. Variation is a four-star alternative that restores 8 Concerto Energy when casting Resonance Skill, once every 20 seconds.
For stats, consider Energy Regen and Max HP. With at least 400 Floral Epistle consumed, Energy Regen above 200% increases the damage of an active teammate with Reflecting Shadows inside Ceaseless Landscape during Roaming Transcendent, up to 12%. At 600, Energy Regen also scales a conditional ATK bonus for a later incoming teammate.
Leveling priority
A suggested order is Song of Thoroughfare, Vernal Screen, Lambent Gold, Tinkling Jade, then Unraveled Spring. This puts the field and the route into Drizzle Stance ahead of the regular attacks. The supplied data does not give level-by-level scaling, so treat the order as a way to organize upgrades rather than a measured damage ranking.
For maximum ascension, gather 170,000 Shell Credit, 4 LF Autopuppet Kernel, 12 MF Autopuppet Kernel, 12 HF Autopuppet Kernel, 4 FF Autopuppet Kernel, 46 Solidarity's Loneflame and 60 Flowborne Dream.
For all skills, gather 2,030,000 Shell Credit, 25 LF Autopuppet Kernel, 28 MF Autopuppet Kernel, 40 HF Autopuppet Kernel, 57 FF Autopuppet Kernel, 26 Skyward Glazed Heart, 25 Spliced String, 28 Broken String, 55 Solidified String and 67 Melodic String.
Resonance Chain nodes worth it
For a support-focused suggestion, consider Clouds Pour Like Molten Gold (Sequence 2) first. It gives nearby teammates in Ceaseless Landscape 50% Crit. DMG for 30 seconds after the listed status actions. The bonus is disabled while the active Resonator is outside the field.
Sparse Curtains Invite Evening Glow (Sequence 3) is worth considering for a faster setup. After the Drizzle Stance Skill, it lets Suisui use the fourth Basic Attack, which consumes Kingfisher to restore 20 Concerto Energy and 350 Floral Epistle. Kingfisher can be consumed once every 25 seconds.
Mountains Washed Into Paintings (Sequence 1) is another support option: it lets Undulating Mist grant its ATK increase after inflicting Negative Status or dealing its damage, and extends Reflecting Shadows from the third Plume Step. The fourth Resonance Chain node increases two sources of healing. The fifth and sixth focus on Suisui's own damage, so they are reasonable to skip if you only want her support.
Teams
The field also raises the stack limit for several statuses when a teammate inflicts them or deals their corresponding status damage. This includes Electro Flare, which raises the limits for both Electro Flare and Electro Rage. Suisui's Outro amplification applies to the team regardless of element.
Common mistakes
Do not switch out as soon as you enter Drizzle Stance if you want its higher thresholds. At 200 Floral Epistle you can unlock the first Plume Step, at 400 the second and at 600 the third, provided Ceaseless Landscape is active. Switching at 600 also unlocks the conditions for Undulating Mist.
Do not let the 15-second stance expire with Floral Epistle stored: leaving it clears the resource. Cast the Liberation before the Outro if you want Roaming Transcendent. Switching Suisui back in stops her Transcendent Dance, and the state ends if Ceaseless Landscape is no longer active.
Do not count on every heal occurring immediately. Enrichment is consumed by an incoming Resonator and also grants Spring's Birth, which heals periodically when that Resonator is not at full HP. Its trigger has a 25-second limit. Keep the active teammate inside Ceaseless Landscape when using its field-dependent bonuses.
