Ardelia

Nature Supporter 6★ Buffer Support tier A Difficulty: Low Rhodes Island

Verdict

Versatile Nature buffer: her Combo gifts free Corrosion and her Battle Skill consumes it to stamp a 30s Physical+Arts Susceptibility that raises every element's damage. On top of that her Friendly Presence sheep heal, so she brings a multiplier and sustain at once — useful even outside Nature comps.

Teams

Ardelia appears in 9 of the 72 curated comps. They're not ranked against each other — on purpose: pick the one that looks fun to play. Open one to see the pitch and the lineup; the full guide is in the app.

Maygi — Physical (Ardelia)

Mi Fu · Chen Qianyu · Pogranichnik · Ardelia

Mid-High CC / Mobs & Elites
PhysicalCrushVulnerabilitySustain

The pure physical core with sustain. Chen Qianyu manufactures Vulnerability, Mi Fu eats it twice per cycle with her double Crush, Pog applies Breach, and Ardelia heals while leaving a very long Physical Susceptibility. The most comfortable of the three.

Zn0nym0us - Mi Fu with Ardelia and Lifeng (better than Pog)

Chen · Ardelia · Lifeng; «better result and much easier» — with a formation rule

Medium (easier than with Pog) Boss (0 energy start)
Better than PogLink into the Chen UltimateFormation order

The last team of the guide and its discovery (1.3 era): «you can substitute Pog with Lifeng — it gave me a much better result and it is much easier to use». Lifeng leaves Physical Susceptibility with his Battle Skill, his Combo gifts the Link that the Ultimate from Chen consumes, and Ardelia adds healing, her double Susceptibility and the damage buff from her Stanza in the burst. Formation rule: Lifeng goes AFTER Ardelia in the team order.

叫我棉被 - Boss (Ardelia)

Xaihi · Gilberta · Ardelia

High Boss / Single-target
CryoPremium bufferDual SusceptibilityUltimate-focused

The boss/hard-content version: Ardelia in the 4th slot instead of the applicator. Her strong buff raises total damage at the cost of less Infliction stacking and less stagger.

In the app 3-step rotation · 4 gear builds · 2 pros / 2 cons · 2 pitfalls · video walkthrough

Zn0nym0us - Yvonne without Gilberta (Perlica and Ardelia)

Perlica · Ardelia · Xaihi; 4.5/5 — high F2P damage on the 90% timing of the Combo from Perlica

High (4.5/5 from the author) Boss / Endgame (no pre-fight prep)
No GilbertaArdelia CorrosionThe 90% clockSustain

The team for whoever lacks Gilberta (1.0-1.1 era): Ardelia takes the seat with her Combo Corrosion, her Physical Susceptibility and the Ultimate healing — without fixing the SP hunger, and with an exclusion rule the author makes plain: Ardelia and Gilberta together, NO — the Vulnerability from the Combo of Gilberta stops the one from Ardelia from firing. High damage and sustain in exchange for the finest timing in the guide short of the 5/5: the Combo from Perlica gets clocked at 90% of its cooldown.

In the app 2-step rotation · 3 pros / 3 cons · 3 pitfalls · 1 matchup note · video walkthrough

Raaay丶 - NO Arcane, Gilberta or Tangtang: Xaihi · Ardelia · Alesh

Yvonne as the only limited: one base axis of 40s laps, the same lap to charge and to burst

Low (a single base axis, «easy to copy» per the author) Boss / Single-target
CryoCorrosionLow budgetNo ArcaneNo GilbertaSingle axis

Raaay丶's low-budget team for players who have Yvonne but not Arcane, Gilberta or Tangtang: Yvonne with Xaihi, Ardelia and Alesh («伊赛羊鱼»). According to the author, it is the low-budget team that best lets you feel Yvonne: SP does not stall and the cycle is short. Ardelia puts Corrosion with her Combo and consumes it with her Battle Skill, which lights the Combo from Alesh; the Ultimate from Alesh and the Combo from Xaihi put the two Cryo layers that the Battle Skill from Yvonne turns into Solidification. You learn a single base axis: the charge lap is the same one without the Ultimates from Xaihi, Yvonne and Ardelia, and the only thing that moves with the fight is Alesh's Ultimate. It also brings a short lap to cold start or get back on track, and build panels for all four.

Zn0nym0us - Rossi with Ardelia and the clean enemy

Pogranichnik · Ardelia · Gilberta; difficulty 3/5 — the circle of dirtying, cashing and cleaning

Medium (3/5 from the author; damage 3.5/5) Boss / Endgame (0 Ultimate at the start)
Clean enemyDouble SusceptibilityPog as the janitorPhysical side

The sheet that explains why Ardelia is not the second best support for Rossi (1.1 era): her Combo only triggers on a Final Strike against an enemy WITHOUT Vulnerability or Arts Infliction — exactly what Rossi needs and manufactures. The solution is Pogranichnik, «the number 1 choice for any team with Ardelia»: his Breach consumes the stacks, returns SP and leaves the enemy clean for the next cycle. 3.5/5 damage, 3/5 difficulty.

叫我棉被 - Laevatain Fire

The classic fire team, now with Link management

Mid
HeatBurstLink managementComfy SP

Laevatain is still the engine: 4 Molten stacks, Enhanced Battle Skill and Ultimate. Camille adds Heat Susceptibility, Weakness, SP refunds and the Link buff for her Enhanced Battle Skills. Antal takes the 4th slot, or Wulfgard if the cold start is very demanding.

YZ-月咒 - Laevatain Fire

Two charge rotations to fill Laevatain's Ultimate and burst: simple axis (stable) or advanced (faster)

Mid (advanced: High)
HeatBurstMoltenTwo axes (simple/advanced)Long cold start

Fire team with Laevatain as carry, Camille and Wulfgard loading Heat and Ardelia (小羊) arming the window. The plan: two identical charge rotations to fill Laevatain's Ultimate, then Ardelia consumes the Corrosion to apply Physical and Arts Susceptibility, everyone ults and you burn. YZ shows two versions: the simple axis (stable, no dupe requirements) and the advanced axis (faster startup by cancelling Wulfgard's Combo with his Ultimate to save 100 SP; needs Wulfgard at potential 5).

Maygi - Arcane · Ardelia · Liino

Arcane (WILL) · Ardelia · Liino

Low Boss / Multi-target
NatureAmpMulti-targetLong rotationSimple

Very strong and simple: Ardelia is fed 100 SP for a massive, long-duration debuff, and Liino, Will-maxed, amplifies with her Ultimate and applies the Electrification Perlica used to. The downside is that only Arcane stacks Nature Infliction, so the rotation stretches to 75 seconds; in exchange it shines against several enemies. 69K team DPS, second in the video.

Ardelia is a Rhodes Island operator assigned to Endfield Industries where she serves as an expert geologist under the framework agreement between the two companies.

Ardelia's early work centered on volcanoes, but today her research extends into Ætherside and geological disasters. She spends most of her time in the field, venturing alone into disaster sites to collect samples, analyze structures, and develop theories that have become the cornerstone of Endfield's Blight countermeasures.

Always humble and polite, she carries an inner strength that never seems to run dry. To her, happiness is simple: climbing another mountain, walking another path, hearing the voices of the world, and uncovering the hidden wonders of this planet.

And if you can become good friends with Ardelia, then Mr. Dolly is sure to like you too.
