Ardelia blends healing with enemy debuffing, so she covers two jobs in one slot. She spreads Corrosion and then converts it into Physical and Arts Susceptibility, raising the whole squad's damage, while her talent keeps allies topped up through Shadows of Mr. Dolly. Because she slots into almost any composition, she earns a top-tier placement.
endgamesupportendgameteam_damage_ampdebuffhealingsupport
This endgame configuration turns Ardelia into a team damage multiplier rather than a pure healer. Dreams of the Starry Beach deepens the Arts damage enemies suffer and improves her own treatment, while the Eternal Xiranite set converts her susceptibility application into a damage bonus for every ally. Redeemer Armor occupies the chest slot for extra Ultimate Gain, which translates into more Wooly Party casts and more Shadows of Mr. Dolly on the field. Pick this version when your damage dealers can dump their cooldowns inside the susceptibility window, since that is when the amplification actually matters.

Explanation
Dreams of the Starry Beach is the top choice because it increases how much Arts damage the marked enemy takes and simultaneously lifts Ardelia's healing output.
The Eternal Xiranite set rewards her debuff application by handing the rest of the team a damage buff once Physical and Arts Susceptibility lands, so the setup benefits everyone and not just Ardelia.
Stanza of Memorials is the swap when the team prefers a shared attack boost, Monaihe is the pick when Ultimate uptime limits healing, and Fluorescent Roc works as a cheaper Will-oriented option.
Notes
- Eternal Xiranite supplies HP, Intellect and Will, and after Ardelia applies susceptibility her teammates also gain a damage dealt bonus for a short time.
- Redeemer Armor is used as the off-piece purely for Ultimate Gain Efficiency, which means more Wooly Party casts and therefore more Shadows.
- Stanza of Memorials, Monaihe and Fluorescent Roc are the listed alternatives and each uses a different essence priority.
endgamesupportendgamehealingsurvivabilitydamage_mitigation
A pure sustain setup for Ardelia. The LYNX set maximizes HP Treatment Efficiency and Will, and its set effect adds damage reduction to whichever ally receives her treatment, which noticeably raises survivability in long fights. It is the version to run when the squad is being ground down rather than racing a damage check. Keep in mind the mitigation portion is conditional: it will not apply to allies Ardelia cannot directly heal, such as uncontrolled characters or during stage effects that share healing across the party.

Explanation
Choose this loadout when the team's problem is staying alive instead of killing faster, since LYNX piles on Treatment Efficiency and Will.
Dreams of the Starry Beach stays as the weapon because it still raises her healing, with the Arts damage amplification treated as a bonus.
Monaihe can be substituted when extra Ultimate recharge matters more, and Fluorescent Roc serves as a budget Will and Attack option.
Notes
- LYNX trades the team damage buff for raw healing power and survivability, and it adds a damage reduction layer on top of each heal.
- The damage reduction only lands on the ally Ardelia actually treats, so it does nothing for uncontrolled teammates.
- Stage effects that spread healing, such as the one in Survive the Gas, do not activate the LYNX buff, though the boosted healing itself still reaches the squad.

A cheap, Will-focused starting setup. The Mordvolt Resistant set floods Ardelia with Will and a little Intellect, and because her healing formula scales with Will the return on that investment is immediate. The battery piece adds treatment bonus, and the set's treatment spike while she is below half HP gives her a bit of emergency recovery. Either Dreams of the Starry Beach or Freedom to Proselytize can sit in the weapon slot here, with Fluorescent Roc offered as another early-accessible option; move to the endgame Eternal Xiranite configuration once better pieces are available.

mordvolt resistant battery
Explanation
Mordvolt Resistant is the easy early set to complete and it feeds the exact stat her healing formula wants, so it outperforms flashier options until better pieces drop.
Freedom to Proselytize adds further Will and lets her treat an additional ally through the weapon effect, which is why it appears in the early game writeup, while Fluorescent Roc is noted as another early-accessible Will option.
Dreams of the Starry Beach remains the eventual upgrade target because it keeps helping after the early game ends.
Notes
- Mordvolt Resistant loads Ardelia with Will plus some Intellect, and since her healing scales off Will the bigger stat line directly equals bigger heals.
- The battery piece raises treatment bonus, stacking with the set's low-HP treatment effect when she dips below half health.
- The source build table lists Dreams of the Starry Beach, while the surrounding text names Freedom to Proselytize for this budget setup, so treat either as usable while you assemble a stronger Arts Unit.
Build Insights
Ardelia occupies the sustain-plus-enable slot. She is not a primary damage dealer; instead she keeps the squad healthy while setting up windows where everyone else hits harder. In practice she works in two beats: the on-field character lands a Final Strike so Eruption Column applies Corrosion, then Ardelia uses Dolly Rush to consume it and stamp Physical and Arts Susceptibility onto the target. Allies should spend their burst skills inside that window. Because healing only happens when the controlled operator walks over Shadows of Mr. Dolly, she wants a team that keeps switching and moving rather than one that parks behind a single carry. She pairs naturally with damage dealers who appreciate amplified Arts and Physical damage, and she can also be built purely as a survival anchor when a fight is a war of attrition.
Core Mechanics
- Eruption Column is the combo trigger: it fires when the controlled operator lands a Final Strike on an enemy without Vulnerable or Arts Infliction, dropping a homing cloud that applies temporary Corrosion and lowers all elemental resistance.
- Dolly Rush eats that Corrosion and replaces it with Physical and Arts Susceptibility; with Mountainpeak Surfer the skill is cast a second time for free while Corrosion is still on the target.
- Friendly Presence spawns Shadows of Mr. Dolly when Dolly Rush connects, and Wooly Party sheep can also spawn them. Touching a Shadow heals the controlled operator, or the lowest-HP ally when they are already full.
Scaling
- Healing values are driven by Will, so early Will investment pays off immediately and keeps improving as the stat rises.
- Her debuff payoff is team-dependent: the susceptibility window only converts into real damage when teammates have cooldowns ready to spend.
- At the start she plays as a straightforward healer, while endgame gear shifts her into a multiplier that raises the entire team's damage.
Character Notes
Ardelia is a Nature-attribute Supporter who works as a healing and debuff hybrid. She keeps the squad alive through Shadows of Mr. Dolly while softening enemies, first by applying Corrosion and then by converting it into Physical and Arts Susceptibility. Because her kit demands that the controlled operator land Final Strikes and physically collect Shadows, she rewards active, character-swapping play instead of passive backline camping. She fits comfortably into almost any lineup, though her damage amplification pays off most in teams built around short burst windows.
Playstyle
- Start a rotation by having the on-field character land a Final Strike so Eruption Column triggers and Corrosion sticks to the enemy.
- Follow immediately with Dolly Rush to strip the Corrosion and convert it into Physical and Arts Susceptibility before allies unload their cooldowns.
- Stay mobile: Shadows of Mr. Dolly only heal when the controlled operator walks over them, so keep repositioning between skills.
- Save Wooly Party for moments when the team needs a heal burst; the scattered sheep chip enemies while also generating extra Shadows.
Strengths
- Fits two roles at once, providing both sustain and two separate damage-amplifying debuffs.
- Healing scales with Will, so gear investment converts straight into bigger numbers.
- Comfortable in a wide variety of compositions thanks to a flexible support kit.
Weaknesses
- Healing requires the player to physically pick up Shadows, so passive play seriously reduces her sustain.
- The susceptibility debuff only matters if teammates can actually spend damage inside the window.
- The LYNX damage reduction does not trigger for uncontrolled allies or from shared-healing stage effects.
Team Guide
f2pf2plow_investmentbeginner
A budget-friendly core where Ardelia handles sustain on her own so the other three slots can be spent on SP generation, extra support, and raw damage. She seeds Corrosion with her Combo Skill and then spends it with her Battle Skill to inflict Physical and Arts Susceptibility, while her Talent keeps the squad healed. Akekuri refills SP, Chen Qianyu adds support pressure, and Endministrator is the main carry whose Final Strike and crystal interactions drive the whole loop. The cycle is cheap and repeatable, making it a good starting point before investing in rarer supports.
Explanation
Ardelia covers sustain and debuffing by herself, leaving three slots open for support, SP, and damage.
Endministrator's Final Strike is the ignition point: it triggers Ardelia's Combo Skill and plants Corrosion on the target.
Chen Qianyu's Combo Skill adds a Vulnerability stack when the carry commits an Ultimate or Battle Skill, which the carry then consumes.
Akekuri's SP refunds keep the loop running once the enemy is stunned or staggered, so the rotation rarely stalls.
Strengths
- Ardelia's Talent handles healing, so no dedicated medic slot is needed.
- The Corrosion into Susceptibility loop raises both Physical and Arts damage the enemy takes.
Rotation
- 1Chain Endministrator's basic attacks until the Final Strike lands; this activates Ardelia's Combo Skill, which applies Corrosion and also fires Endministrator's Combo Skill.
- 2Consume the Corrosion with Ardelia's Battle Skill. It resolves twice for extra damage, creates additional healing sheep, and applies Physical and Arts Susceptibility.
- 3Use Endministrator's Ultimate to pop the crystal, or their Battle Skill if the Ultimate is not charged; either one triggers Chen Qianyu's Combo Skill and adds a Vulnerability stack.
- 4Spend the Vulnerability stack with Endministrator's Battle Skill, then restart the cycle from the first step.
- 5While the enemy is stunned or staggered, use Akekuri's Combo Skill for an SP refund, or her Ultimate for a bigger refund to restart the rotation faster.
Seed Corrosion, spend it with Ardelia's Battle Skill for Susceptibility, pop the carry's crystal and Ultimate to gain a Vulnerability stack, consume that stack, then repeat while using Akekuri's SP refills whenever the enemy is staggered.
bestgeneralist
The page's headline generalist example puts Laevatain in the main damage slot, Wulfgard in the sub-DPS/support slot, Akekuri on SP duty, and Ardelia on sustain. Ardelia applies Corrosion with her Combo Skill and then burns it with her Battle Skill to slap Physical and Arts Susceptibility onto the target, which is what makes the carry's numbers climb. Two swaps are noted: Arcane can take Wulfgard's place, and Camille can substitute for Akekuri when she isn't built. Because the debuffs boost both damage types, the carry slot can be swapped without breaking the core.
Explanation
Ardelia spends her Corrosion in this lineup to stack Susceptibility on the target, which is what amplifies Laevatain's output.
Wulfgard fills the sub-DPS/support slot, with Arcane listed as the alternative pick for that role.
Akekuri fuels the rotation with SP; Camille is named as a stand-in for her.
Since Susceptibility raises Physical and Arts damage alike, the main carry can be changed freely around Ardelia's debuffs.
alternativegeneralist
One of the alternative generalist lineups shown on the page: Ardelia in the sustain slot, Perlica as sub-DPS/support, Arclight on support, and Avywenna as the main damage dealer. Ardelia works exactly the same way here as in every other composition — she seeds Corrosion with her Combo Skill, then spends it with her Battle Skill to apply Physical and Arts Susceptibility, while her Talent keeps the team topped up so nobody else has to carry healing duties. Perlica adds secondary pressure and utility while Arclight leaves Avywenna free to concentrate on damage.
Explanation
Ardelia handles sustain and debuffing, letting Perlica and Arclight cover pressure and utility instead of healing.
Arclight sits in the support slot so Avywenna can commit fully to dealing damage.
The Corrosion into Susceptibility loop is identical to the standard pattern: plant the debuff, then spend it to boost the carry.
alternativegeneralist
Another generalist sample from the page: Tangtang occupies the sub-DPS/support slot, Xaihi handles support, Yvonne carries the team's damage, and Ardelia anchors it as the sustain option. Her role stays constant — apply Corrosion, consume it with the Battle Skill to place Physical and Arts Susceptibility, and let her Talent supply healing so no slot is sacrificed for a medic. Because the debuff covers both damage types, Yvonne's hits scale directly off Ardelia's setup, making the pairing effective against tougher targets.
Explanation
Tangtang provides secondary damage and support while Xaihi keeps the support slot filled.
Ardelia's healing Talent removes the need for a dedicated medic, preserving a slot for offense.
Physical and Arts Susceptibility from Ardelia lifts Yvonne's damage against sturdier enemies.
alternativegeneralisthybrid_team
This hybrid composition leans on the interaction between Ardelia's Corrosion and Gilberta's Combo Skill. Her Corrosion doubles as the trigger for Gilberta's Combo Skill, which grants a Vulnerable stack without any SP cost — enough to kick off Rossi's skill chain and sustain it until the main carry consumes the stacks for Crush. Rossi fills the sub-DPS/support slot, Gilberta stays in support, and Endministrator is the default carry, with Mi Fu offered as an alternative for that slot. Ardelia's sustain keeps the shell stable while the team stacks and spends Vulnerable.
Explanation
Ardelia's Corrosion acts as the trigger for Gilberta's Combo Skill, generating a Vulnerable stack at no SP cost.
That free Vulnerable stack starts Rossi's skill chain and keeps it running until the carry spends the stacks for Crush.
Gilberta remains in the support slot while Rossi supplies sub-DPS and support pressure.
Endministrator is the default carry; Mi Fu is listed as the alternative pick for the same slot.
Strengths
- The Corrosion and Gilberta interaction produces Vulnerable without spending SP, which speeds up the opener.
- Ardelia's sustain holds the hybrid core together while it stacks and consumes Vulnerable.
Team Insights
Ardelia is a flexible sustain-and-support hybrid who fits into practically any lineup. Her kit revolves around planting Corrosion with her Combo Skill and then spending that Corrosion with her Battle Skill to inflict Physical and Arts Susceptibility, which raises the damage the target takes from both damage types. Because her Talent supplies healing, teams rarely need a dedicated medic, freeing a slot for another damage or utility unit. She is best paired with a strong main carry plus a support or SP provider, since she amplifies damage rather than dealing it herself. In mixed lineups her Corrosion can also serve as a trigger for other characters' combo skills, turning the debuff into an engine for the whole team.
Synergy Patterns
- Pairing her with a Physical or Arts carry makes the Susceptibility debuff pay off, since the extra damage taken applies to both damage types.
- In hybrid lineups her Corrosion also triggers Gilberta's Combo Skill, giving a Vulnerable stack without SP and starting Rossi's chain until the main carry eats the stacks for Crush.
- Akekuri's Combo Skill and Ultimate refund SP whenever the enemy is stunned or staggered, which lets the team loop its rotation again.
- Endministrator's Final Strike and crystal pops slot into her cycle: the Combo Skill plants Corrosion, and the Ultimate or Battle Skill trigger Chen Qianyu's Combo Skill for Vulnerability.
Tips
- Apply Corrosion first, then consume it with the Battle Skill — spending Corrosion makes the Battle Skill resolve twice and spawn extra healing sheep.
- If the carry's Ultimate isn't ready, substitute their Battle Skill; the combo chain still advances.
- Swap the supporting cast to match the element you are building for, since Ardelia works in Heat, Cryo, Electric, and mixed compositions.
- Against stunned or staggered enemies, squeeze in Akekuri's SP-restoring skills to cut downtime between rotations.

A geologist working under Rhodes Island, Ardelia studies how the Ætherside relates to geological disasters and specializes in volcanic activity, research that brought her into contact with the Endministrator. She is described as gentle, yet she brings both offense and defense to the battlefield with a distinctive style that has her fighting beside a pink sheep named Mr. Dolly. She is treated as the reconvener of Arknights' Eyjafjalla, a link hinted at through matching volcanic and sheep imagery and through her Baker chats about an obsidian taken from a volcano in Siesta.
