Where these rankings come fromThe weapon order, gear sets and Potential verdicts on this tab are prydwen.gg’s, measured in play and condensed to a sentence each. Relative damage figures are ratios against the bottom of each ranking, not absolute numbers, and each one holds only for the Potential and team its row states. Everything else (base stats, skill text, material totals) is read from the game’s own data.

Weapons

Gear

Eternal Xiranite gear set | Arknights: Endfield
CoreEternal Xiranite

Eternal Xiranite is the standard pick for supports who can trigger its team buff, and Ardelia's Susceptibility from her Battle Skill activates it, though not consistently enough on its own for full uptime.

3PC3-piece set effect: Wearer's HP +1000. After the wearer applies Amp, Protected, Susceptibility, or Weakened, other teammates gain DMG Dealt +16% for 15s. This effect cannot stack.

    Dolly Paradise

    Adds a notable flat amount to the Susceptibility from Ardelia's Battle Skill, a solid supportive upgrade for any team and one of her most impactful potentials.

    In game

    Battle skill Dolly Rush improved: Consuming Corrosion now applies Physical Susceptibility and Arts Susceptibility with effects +8%.

  • P5

    Volcanic Steam

    Cuts Ardelia's combo cooldown by 2 seconds, boosts its damage, and extends Corrosion from 7 to 11 seconds, though the extra duration matters less in fights where every combo gets used right away.

    In game

    Combo skill Eruption Column improved: Length of cooldown -2s; DMG multiplier is increased to 1.2 times the original; duration of Corrosion applied +4s.

Every Potential Ardelia has, in full, is on the Kit tab. This is only which of them are worth the pulls.

Teams

Mi Fu team

Physical · Vulnerable and CrushPlays Supporter · HP treatment

Mi Fu groups and Crushes in the same rotation, so Physical finally has an answer to multi-enemy stages without giving up its burst. Chen Qianyu builds the Vulnerable stacks fast enough that the squad rarely waits on them, and the fourth slot flexes between Pogranichnik’s SP and Ardelia’s healing depending on what the stage needs.

  4. Ardelia, Nature Supporter operator | Arknights: EndfieldArdelia, this operatorSupporter · HP treatment

Laevatain team

Heat · CombustionPlays Supporter · HP treatment

Combustion needs a non-Heat infliction already on the target, so Wulfgard or Camille does the stacking while Laevatain triggers it. Her four Melting Flame stacks take time to build, which is the gap newer Heat carries have started to close.

Estella team

Cryo/Physical · Solidification into ShatterPlays Supporter · HP treatment

Solidify from Alesh gets Shattered by a Crush from Estella or Endministrator for Physical damage neither Cryo nor Physical paid for alone. It is a speedrunning niche rather than a generalist pick: most stages end before the squad needs its full rotation.

Da Pan team

Physical · Lift into CrushPlays Supporter · HP treatment

Da Pan carries both halves of the Physical loop, Lift to stack Vulnerable and Crush to spend it, which is rare enough at 5-star to build a squad around. Chen Qianyu doubles the stacking rate, and the last two slots flex between SP and healing depending on the stage.

Every slot here comes from the standard pool or the story, so it is the squad a new account can actually field. Endministrator Crushes what Chen Qianyu Lifts, and Pogranichnik’s Breach spends whatever is left before the stacks reset.

Rossi team

Arts · Ultimate burstStands in for Gilberta

Rossi’s Ultimate alone kills most enemies, so this build stacks Arts Reactions ahead of it rather than leaning on her Physical side. Perlica’s Electric and Tangtang’s Cryo both feed the burst, and the fourth slot is whichever buffer gets the most out of the one cast that matters.

Ardelia FAQ

What attribute is Ardelia?
Ardelia is a 6-star Nature operator of the Supporter class, from Rhodes Island, wielding a Arts Unit, released in version 1.0.
What stat does Ardelia scale on?
Ardelia's skills multiply ATK. That is read from the scaling rows on the Battle Skill and Ultimate, not from the skill description, so it reflects what the game actually multiplies rather than what the text mentions.
What is the best weapon for Ardelia?
Dreams of the Starry Beach is the closest fit on the data: it is a 6-star Arts Unit with 495 base ATK at level 90, and its skills act on ATK. Hypernova Auto is the best 4-star alternative.
Which gear set should Ardelia use?
Eternal Xiranite. Its 3-piece effect is: 3-piece set effect: Wearer's HP +1000. After the wearer applies Amp, Protected, Susceptibility, or Weakened, other teammates gain DMG Dealt +16% for 15s. This effect cannot stack. The 3-piece effect is the only set bonus a gear set has, and it needs three matching pieces; an operator equips four in all (Armor, Gloves and two Kits), so the fourth is free for an off-set piece.
How much does it cost to max Ardelia's skills?
Taking one combat skill from level 1 to 12 costs 172,200 T-Creds and 21× False Aggela among other materials. The Materials tab lists every item per level.
What does Ardelia P1 do?
Dolly Paradise: Battle skill Dolly Rush improved: Consuming Corrosion now applies Physical Susceptibility and Arts Susceptibility with effects +8%.
