Advanced Builds

S
supporthealerdebuffer
Ardelia sits in the top overall tier because she compresses two jobs into one slot: a Nature-attribute debuffer who shreds enemy defenses and a healer who keeps the whole squad topped up through her Talent. Her Corrosion into Susceptibility rotation directly raises the team's damage ceiling, and the same kit spreads healing without spending extra actions, so she fits almost any composition.
endgamesupportendgameteam_buffdebuffhealingsusceptibility
This endgame support build leans into the fact that Ardelia is a force multiplier before she is a healer. Dreams of the Starry Beach amplifies Arts damage taken by the target and simultaneously boosts her healing, so every Corrosion consumed by Dolly Rush pays off twice. Eternal Xiranite supplies HP for durability along with Intellect and Will, and its rider converts any Amp, Protected, Susceptibility, or Weakened application into a flat damage increase for the rest of the team, which is exactly the debuff she applies constantly. Redeemer Armor is deliberately worn as an off-piece to trade a small amount of set value for Ultimate Gain Efficiency, because more Ultimates means more Shadows of Mr. Dolly from her Talent. The net result is a support who raises the party's damage floor while quietly keeping everyone alive.

Explanation

Dreams of the Starry Beach is the headline pick because it deepens the Arts damage enemies take on top of her Susceptibility, and it also lifts her own healing and Will.
Eternal Xiranite is chosen over a pure healing set because the HP on the set raises her survivability while the four-piece rider hands the rest of the team a damage buff whenever she applies her debuff.
Redeemer Armor replaces one set slot because its Ultimate Gain Efficiency matters more than the marginal set-bonus loss, since her Talent's healing is tied to Ultimate access.
Swap in Stanza of Memorials if the group wants a team ATK boost, Monaihe if Ultimate uptime is the bottleneck, or Fluorescent Roc as a cheaper Will-focused stand-in.

Notes

  • Eternal Xiranite turns Ardelia's Physical and Arts Susceptibility into a squad-wide damage amp for a short window after she applies it.
  • Redeemer Armor is worn as the off-slot for its Ultimate Gain Efficiency, feeding extra Ultimate casts into her heal-over-time Talent.
  • The paired Auxiliary Arms push Ultimate Gain further, so the whole set keeps her cycling debuffs and healing faster.
endgamesupportendgamehealingdamage_reductionsustain
Where the support build multiplies team damage, this variant focuses purely on keeping the squad upright. LYNX supplies a large pool of Will and Treatment Efficiency so every Shadow of Mr. Dolly collected by the controlled operator heals for noticeably more, and the set rider converts that healing into a 15% damage reduction for the recipient, escalating to 30% when the heal exceeds their maximum HP. Dreams of the Starry Beach remains the recommended weapon since it enhances her healing and still chips in extra Arts vulnerability. The tradeoff is that the mitigation rider is inconsistent: it cannot trigger on allies you are not directly controlling, and shared-healing stage effects such as Survive the Gas do not count as her giving treatment. Use this configuration when raw damage output is already covered and the team needs a safety net.

Explanation

Dreams of the Starry Beach stays the weapon of choice because its stat spread still supports healing while adding extra Arts damage taken by the enemy.
LYNX is picked over Eternal Xiranite when survival is the priority: the set stacks Will and Treatment Efficiency so each Shadow of Mr. Dolly restores much more HP.
The set rider turns her heals into mitigation, which is valuable against burst damage that raw healing cannot outpace.
Keep in mind that the mitigation is conditional; if your team spends most of the fight off-field, the extra healing still spreads to the group, just without the reduction.

Notes

  • LYNX maxes out Treatment Efficiency and adds a damage reduction rider to whoever receives her healing, which raises party survivability rather than just raw numbers.
  • If the healing exceeds the ally's maximum HP, the reduction jumps to a stronger tier, so overhealing low-HP targets is still productive.
  • The LYNX rider will not fire on allies the player is not controlling, because they cannot walk over Shadows of Mr. Dolly to be healed.
  • Stage-granted shared healing, as seen in Survive the Gas, also fails to trigger the LYNX reduction.
early gamesupportbeginnerf2phealingwill_scalingprogression
This is the budget entry point for players who have just pulled Ardelia and want her to function immediately. Because her healing is calculated from Will, the whole setup is built around stacking Will: Mordvolt Resistant supplies a big Will bonus along with Intellect, and its battery pieces add Treatment Bonus, while the set's low-HP rider increases Treatment Effect when fights get dangerous. Freedom to Proselytize continues that theme and also lets her heal an additional ally with its effect, which matters in the early game when one extra heal can carry a fight. Fluorescent Roc is listed as a cheaper alternative that still provides Will and a small Attack bump. Nothing here is fancy, but the Will stacking keeps her relevant until better weapons and LYNX or Eternal Xiranite become available.

Mordvolt ResistantHealing Boost

armor

mordvolt resistant vest t1

gloves

mordvolt resistant gloves

core 1

mordvolt resistant battery

core 2

mordvolt resistant battery

Explanation

The source text pairs the beginner setup with Freedom to Proselytize, since pumping Will is the cheapest way to make her heals meaningful before better gear is available.
Mordvolt Resistant is the accessible set that provides the Will and Intellect she wants, and the battery core slots contribute Treatment Bonus on top.
Fluorescent Roc appears in the general weapon ranking as an early-game option because it mirrors the Will-focused approach with a bit of extra Attack.
Once better gear and weapon options open up, move to a Dreams of the Starry Beach or LYNX configuration for stronger sustain.

Notes

  • Mordvolt Resistant is chosen because Ardelia's healing formula reads off Will, and the set hands out a large chunk of Will plus Intellect.
  • The set also raises Treatment Effect while she is under half HP, which is a useful safety valve during rough early fights.
  • Freedom to Proselytize adds yet more Will and lets her extend a heal to a second ally through its weapon effect.
  • Fluorescent Roc is a serviceable stand-in early on since it also supplies Will along with some Attack.

Build Insights

Ardelia is a Nature-attribute Supporter who plays as a hybrid debuffer and sustain unit rather than a pure damage dealer. Her offensive contribution comes from the Corrosion-to-Susceptibility chain: a teammate's Final Strike lets Eruption Column land Corrosion, then Dolly Rush converts it into Physical and Arts Susceptibility, amplifying everything her allies do afterwards. With Eternal Xiranite equipped she converts that same debuff into a party-wide damage aura, so she scales best next to a main damage dealer who can reliably finish enemies and eat the enlarged damage window. Defensively she blankets the field with healing via Shadows of Mr. Dolly, and picking those up with the controlled operator is the primary way the team stays alive. That makes her positioning flexible: she wants to be near the action so the Shadows spawn close to whoever needs them, but she never has to be the one carrying the damage. Because her trigger depends on the controlled operator landing a Final Strike, she works in almost any composition that has a competent on-field attacker, and the Awakening Sign-In handout means many players already own her.
Core Mechanics
  • Eruption Column (Combo Skill) only fires when the controlled operator lands a Final Strike on an enemy carrying no Vulnerability or Arts Infliction, then forces temporary Corrosion onto nearby foes.
  • Dolly Rush (Battle Skill) eats that Corrosion to stamp Physical and Arts Susceptibility on the target, which is what actually opens up the team's damage window.
  • Talent Mountainpeak Surfer recasts Dolly Rush once per activation at no cost whenever a Corroded enemy is within range.
  • Talent Friendly Presence drops Shadows of Mr. Dolly from Dolly Rush and, at a low chance, from Ultimate copies; touching one heals the controlled operator or the lowest-HP ally if they are already full.
  • Wooly Party (Ultimate) is a mobile channeling state that scatters damage-dealing Mr. Dolly copies in random directions.
Scaling
  • Her healing output is driven by Will, so anything that raises Will or Treatment Efficiency directly increases how much she restores per Shadow pickup.
  • Susceptibility strength climbs with Battle Skill investment, making that skill the one to upgrade first if you want the team's damage to grow.
  • She performs fine on a budget because the core loop is refundable through Mountainpeak Surfer, but she really takes off once her Talent levels and endgame gear are online.

Character Notes

Ardelia is a 6-star Nature-attribute Supporter who fights with an Arts Unit and serves as a combined debuffer and healer. Her identity revolves around Corrosion: her Combo Skill applies it, and her Battle Skill consumes it to inflict Physical and Arts Susceptibility on the target, widening the damage window for the rest of the squad. The same Battle Skill, boosted by her Friendly Presence Talent, scatters Shadows of Mr. Dolly that heal whoever picks them up. Because both halves of her kit are low-maintenance and her Ultimate doubles as area damage and healing, she slots comfortably into many compositions as the all-rounder who keeps the team healthy while making enemies easier to kill. She also happens to be one of the easier six-stars to acquire, since she was distributed through an event sign-in as well as headhunting banners.
Playstyle
  • Open the engagement by letting the controlled operator land a Final Strike on a clean target so Eruption Column can attach Corrosion.
  • Follow up with Dolly Rush while Corrosion is still on the enemy to trade it for Physical and Arts Susceptibility.
  • Keep an eye on the free recast from Mountainpeak Surfer; standing near a Corroded enemy lets the Battle Skill fire a second time for no cost.
  • Walk the controlled operator over the Shadows of Mr. Dolly that spawn around the battlefield to convert them into healing.
  • Save Wooly Party for moments when the team needs healing and a little extra chip damage at the same time.
  • Leave her Basic Attack at base level; her value comes from skills and the Talent-driven healing loop, not auto-attack damage.
Strengths
  • Provides two roles in one team slot, applying Physical and Arts Susceptibility while simultaneously healing allies.
  • Corrosion reduces enemy resistance against every element, which benefits allies regardless of their damage type.
  • Healing scales off Will rather than Attack, giving her a straightforward and forgiving gearing path.
  • Her Talent can top up an ally who is already at full HP by redirecting the heal to the lowest-HP teammate.
  • Ultimate doubles as area damage and a healing window, and it can also spawn extra Shadows of Mr. Dolly at a low chance.
  • Dolly Rush can be recast for free through Mountainpeak Surfer, increasing both debuff and heal output per rotation.
Weaknesses
  • Her Combo Skill is gated behind the controlled operator landing a Final Strike on an enemy that has no Vulnerability or Arts Infliction stacks.
  • The healing Shadows of Mr. Dolly must be physically picked up, so allies you are not controlling cannot benefit from them directly.
  • The LYNX damage reduction rider will not trigger on non-controlled allies, nor from stage-granted shared healing effects.
  • Basic Attack upgrades are largely wasted on her because her damage contribution is incidental.
  • Her damage windows depend heavily on a teammate setting up the Final Strike, making her less effective in a passive or low-activity squad.

Team Guide

f2pf2pbeginnerlow_investmentcorrosion_team
Ardelia covers the sustain slot while doubling as a debuffer for Endministrator, the team's main damage source. Akekuri and Chen Qianyu fill the support slots, refunding SP and stacking Vulnerability so the carry can keep bursting. Ardelia's Combo Skill plants Corrosion on the target, and her Battle Skill then eats it to apply Physical and Arts Susceptibility, so even a modestly invested roster hits noticeably harder. It is an easy, cheap core that works in almost any fight.

Endministrator

Explanation

Ardelia works as both sustain and support, so she can be dropped into nearly any roster to keep allies alive while raising their damage output.
Cycling her Combo Skill into Battle Skill applies Corrosion and then strips enemy resistance with Physical and Arts Susceptibility.
Akekuri refills SP so the loop restarts quickly, while Chen Qianyu's Combo Skill adds a Vulnerability stack for the DPS to consume.

Strengths

  • Very low investment requirement; only Ardelia is a headline unit and the rest are easily obtainable.
  • Debuffs amplify both Physical and Arts damage, so the team is not locked into one damage type.
  • Strong self-sustain between Ardelia's healing sheep and Akekuri's SP refunds.

Weaknesses

  • Peak damage is lower than dedicated element-focused compositions.
  • Loses value if the rotation is mistimed and Corrosion or Vulnerability stacks fall off.

Rotation

  1. 1Attack with Endministrator until the Final Strike lands, which fires Ardelia's Combo Skill, applies Corrosion to the target, and also triggers Endministrator's own Combo Skill.
  2. 2Cast Ardelia's Battle Skill to consume the Corrosion, stacking Physical and Arts Susceptibility so the enemy takes more damage from every source.
  3. 3Use Endministrator's Ultimate to shatter the crystal; if the Ultimate is not up, fall back on the Battle Skill. Either way, Chen's Combo Skill triggers and adds a Vulnerability stack.
  4. 4Spend the Vulnerability stack with Endministrator's Battle Skill, then loop the sequence from the start.
  5. 5Whenever the enemy is stunned or staggered, fire Akekuri's Combo Skill for an SP refund, and use her Ultimate for a bigger refund to restart the rotation.
Cycle Corrosion into Battle Skill consumption, then pop the crystal with Endministrator's Ultimate to trigger Chen's Vulnerability for the carry to spend.
alternativeheat_teamcorrosion_teamalternative
A Heat-leaning variant of the generalist shell, with Laevatain as the primary damage dealer and Wulfgard as a sub-DPS who also chips in support. Akekuri keeps skill costs manageable with SP refunds while Ardelia handles sustain and resistance shredding. The team's mixed Physical and Arts profile benefits directly from Ardelia's Susceptibility debuffs, so the supports do not have to be element-matched to be useful.

Wulfgard can be swapped for Arcane in the sub-DPS/support slot without changing the team's role structure.
Akekuri can be replaced by Camille in the support slot if a different utility profile is preferred.
Ardelia's Corrosion consumption buffs both damage types, so the team is not punished for running mixed-damage allies.

Strengths

  • Flexible sub-DPS and support slots make this comp easy to adapt to the units you own.
  • Heat carry plus Ardelia's debuffs gives strong single-target pressure.

Weaknesses

  • Needs Ardelia to keep Corrosion active or the damage gain from Susceptibility disappears.
elementalcryo_teamcorrosion_teamalternative
A Cryo-oriented setup where Ardelia anchors the sustain slot and stacks debuffs, Perlica provides sub-DPS and utility pressure, Arclight supplies support, and Avywenna carries the damage. Ardelia's Combo Skill applies Corrosion and her Battle Skill converts it into Physical and Arts Susceptibility, so the whole squad's hits land harder regardless of damage type. The extra healing sheep from the Battle Skill keep the frontline stable during longer fights.

Explanation

Ardelia is element-agnostic: her Corrosion, Susceptibility, and healing work in a Cryo shell just as well as anywhere else.
Perlica occupies the sub-DPS/support slot, adding damage while Ardelia maintains debuff uptime.
Avywenna benefits most from the resistance shred, making her the natural stack consumer for the rotation.

Strengths

  • Debuff-driven damage scaling means the team keeps up even without perfect element matching.
  • Two layers of support plus Ardelia's healing make it forgiving in sustained fights.

Weaknesses

  • Without Corrosion upkeep, the Cryo carry loses a large chunk of its effective damage.
elementalelectric_teamcorrosion_teamalternative
An Electric-focused arrangement built on the same support skeleton, with Yvonne as the main DPS, Tangtang filling the sub-DPS/support slot, and Xaihi providing support. Ardelia keeps everyone alive and applies the debuffs that make the damage stick. Because her Corrosion reduction and Susceptibility affect both Physical and Arts sources, the team does not need to be perfectly element-tuned to perform well.

Explanation

Tangtang adds damage and utility without competing with the carry for the same role.
Xaihi rounds out the support slot so Ardelia can focus on sustain and Corrosion management.

Strengths

  • Low maintenance core: the same rotation applies across elements.
  • Debuff pressure from Ardelia raises the whole team's effective damage.

Weaknesses

  • Damage output falls off if the enemy clears debuffs or the rotation is interrupted.
advancedhybrid_teamcorrosion_teamburst_teamadvanced
A hybrid composition that turns Ardelia's Corrosion into a combo engine. Gilberta's Combo Skill fires off the Corrosion, handing the team a Vulnerable stack without spending SP, which lets Rossi get her skill sequence rolling. The stack then gets spent by the main carry for a Crush finisher. Endministrator takes the carry slot here, though Mi Fu can be substituted for a different damage profile, while Ardelia keeps the team healthy and cycling debuffs.

Explanation

In hybrid lineups, Ardelia's Corrosion does double duty as a trigger for Gilberta's Combo Skill, generating Vulnerability at no SP cost.
That free Vulnerable stack kickstarts Rossi's skills until the main carry consumes the stacks for Crush.
Endministrator can be swapped for Mi Fu in the DPS slot depending on the player's roster.

Strengths

  • Corrosion doubles as a combo trigger, giving the team resource-free Vulnerability stacks.
  • Very high burst ceiling once Vulnerability stacks line up with Rossi and the carry's finishers.

Weaknesses

  • Demands precise sequencing; a broken chain wastes the free Vulnerable stacks.
  • Higher investment than the budget core.

Team Insights

Ardelia is a sustain-and-support hybrid, which makes her one of the most flexible anchors in the game: she can be slotted into Heat, Cryo, Electric, or hybrid squads without changing what she does. Her job is to keep the team healthy with her Talent's healing while applying Corrosion through her Combo Skill, then converting that Corrosion with her Battle Skill to inflict both Physical and Arts Susceptibility. Because those debuffs are element-agnostic, the surrounding team can be built purely around whichever main DPS you want to amplify, with supports chosen to feed resources or stack additional Vulnerability. In hybrid setups her Corrosion also serves as a trigger for other characters' Combo Skills, turning her into the engine that starts the burst chain rather than just a defensive pick.
Synergy Patterns
  • Combo Skill applies Corrosion, and Battle Skill consumes it to boost the Battle Skill's own damage, spawn more healing sheep, and add Physical and Arts Susceptibility.
  • Endministrator's Final Strike from basic attacks can trigger Ardelia's Combo Skill, giving the pair a reliable Corrosion loop.
  • Debuff stacking with Chen Qianyu's Combo Skill, which adds Vulnerability for the main DPS to consume.
  • In hybrid teams, Ardelia's Corrosion triggers Gilberta's Combo Skill, producing a Vulnerable stack without SP and enabling Rossi's Crush payoff.
  • Akekuri's Combo Skill and Ultimate restore SP on stun or stagger, letting the whole rotation restart.
Tips
  • Always pair her Combo Skill with her Battle Skill — the Corrosion consumption is where most of her value comes from.
  • Hold Akekuri's SP refunds until after the carry has spent its burst so the rotation can immediately restart.
  • Keep an Ultimate available for crystal popping if you run Endministrator; otherwise substitute the Battle Skill without losing the reaction chain.
  • Ardelia fits any element, so pick the main DPS first and then build supports around feeding that carry.
  • Track debuff timers: losing Corrosion or Vulnerability mid-rotation is the biggest damage loss for these comps.

Ardelia is a Caprinae geologist attached to Rhodes Island whose research into the link between the Ætherside and geological disasters brought her alongside the Endministrator. Her specialty is volcanic activity, and she takes the field accompanied by a pink sheep she calls Mr. Dolly. She is regarded as an Eyjafjalla reconvener: her Baker chat mentions an obsidian from a Siesta volcano, she shares the volcanic and sheep imagery, and Eyjafjalla's silhouette appears in the Reconvener Nexus Files. Soft-spoken by nature, Ardelia supports her squad both offensively and defensively through her unusual combat style.
