supporthealerdebuffer
Ardelia earns a top-tier rating as a Nature sustain Supporter: she can debuff enemies with Corrosion then Physical and Arts Susceptibility, while her Talent provides reliable healing. Despite a low reroll rating, her healing, debuffs, and team-wide damage amp make her an all-rounder in many compositions.

This endgame support build turns Ardelia into a damage-amp sustain: the Eternal Xiranite set rewards her debuffing rotation with a team-wide +16% damage buff, and the Redeemer Armor off-piece accelerates Ultimate gain for more frequent healing. With Dreams of the Starry Beach increasing Arts damage taken and healing output, Ardelia simultaneously boosts team damage and keeps the party alive.

Explanation
Eternal Xiranite's 4-piece effect is a natural fit because Ardelia constantly applies Susceptibility to enemies, activating the team damage amp.
The off-piece Redeemer Armor boosts Ultimate generation, so she can use her Talent-based healing more frequently.
Stanza of Memorials can replace the signature weapon if you want a team ATK buff, while Monaihe speeds up Ultimate recharges.
Notes
- Uses Eternal Xiranite set to convert her Susceptibility application into a team-wide +16% damage buff for 15s.
- Redeemer Armor is the off-piece for Ultimate Gain Efficiency, letting her cycle her healing Ultimate more often.
- Dreams of the Starry Beach adds Arts Damage taken and improves her healing.
endgamesupportendgamehealersustaindmr_reduction
This endgame healer build focuses on maximum healing output. The LYNX set gives +20% HP Treatment Efficiency and adds a temporary 15% DMG Reduction to allies Ardelia heals. Combined with Dreams of the Starry Beach, her heals become stronger and she also increases Arts damage taken by enemies. It is the best choice for content that demands long-term survivability, though the LYNX buff only triggers on direct controlled healing.

Explanation
LYNX's set bonus directly improves both healing amount and survivability by granting damage reduction to targets she heals.
As she frequently picks up Shadows of Mr. Dolly, the team benefits from consistent healing and the accompanying tankiness boost.
Use this route when your team needs sustain more than an additional damage buff; the Eternal Xiranite set can be swapped in for more offensive support.
Notes
- LYNX set grants +20% HP Treatment Efficiency and adds a 15% DMG Reduction to healed allies for 10s.
- The DMG Reduction buff does not trigger from shared healing on effects like Survive the Gas or on non-controlled allies.
- This build maximizes raw healing output with Will and Treatment Efficiency, making Ardelia a dedicated healer.
early gamesupportearly_gamebeginnerhealerf2p
This early game build for Ardelia uses the Mordvolt Resistant gear set and the Freedom to Proselytize weapon to maximize her healing through Will stacking. The set provides Will and Intelligence, and its low-HP Treatment bonus can save her in tight situations. While not as strong as endgame sets, it is an easy-to-obtain option for new players that turns her into a reliable sustain support.

Explanation
Early on, stacking Will directly increases the healing from Friendly Presence, so Mordvolt Resistant's Will boost is perfect.
The set's Treatment Effect bonus when below 50% HP helps Ardelia sustain herself in dangerous fights.
Freedom to Proselytize is chosen because it grants Will and a second-target heal; Fluorescent Roc is a fallback that also gives Will and some ATK.
Notes
- Mordvolt Resistant set provides Will and Intelligence for bigger heals, with a conditional Treatment Effect bonus when under 50% HP.
- Freedom to Proselytize adds even more Will and lets her heal an extra ally, making her a solid early sustainer.
- If you have Dreams of the Starry Beach, it can replace Freedom for stronger healing and enemy debuffing, but Freedom is a good early pick.
Build Insights
Ardelia fills a sustain/debuffer slot in teams. She enables damage by applying Corrosion and then consuming it for Physical/Arts Susceptibility, and her healing from Shadows of Mr. Dolly keeps the controlled operator healthy. She fits well in endgame teams that want both survivability and a damage amp, as the Eternal Xiranite set lets her grant teammates +16% damage after applying Amp, Protected, Susceptibility, or Weakened. In pure survival comps, the LYNX set adds damage reduction on top of her heals. She can act as the main support in a wide range of team compositions, especially where sustained HP management and debuffs are needed.
Core Mechanics
- Ardelia's Combo Skill Eruption Column applies Corrosion to enemies, lowering their elemental resistance.
- Dolly Rush consumes Corrosion to apply Physical and Arts Susceptibility, boosting incoming damage.
- Her Talent Friendly Presence creates Shadows of Mr. Dolly that heal the controlled operator on touch; she can heal the lowest-HP ally instead if the controlled operator is full.
- Her Ultimate Wooly Party deals Nature damage and has a chance to spawn more healing Shadows, enabling sustainable team healing.
Scaling
- Healing from Friendly Presence scales with Will, making Will and Treatment Efficiency her most valuable stats.
- She is strong from early game and only improves with the Eternal Xiranite set's team damage buff and the LYNX set's damage reduction.
- Her debuffing potential (Corrosion into Susceptibility) makes her valuable even at low investment, but she becomes a true team enabler with endgame gear.
Character Notes
Ardelia is a 6-star Nature Supporter who excels as a sustain and debuff character. She can apply Corrosion to enemies, consume it for Physical and Arts Susceptibility, and heal allies through her Talent's Shadows of Mr. Dolly. Her kit makes her an all-rounder: she boosts the team's damage while keeping everyone alive. She is available from Headhunting banners and the Awakening Sign-In event.
Playstyle
- Start encounters by triggering Eruption Column via a Final Strike on an enemy without Vulnerable or Arts Infliction to apply Corrosion.
- Follow up with Dolly Rush to consume Corrosion and apply Physical and Arts Susceptibility, increasing incoming damage.
- Use Wooly Party to heal: pick up Shadows of Mr. Dolly with the controlled operator, or let the copy heal the lowest-HP teammate.
- Position Ardelia so the controlled operator can easily touch Shadows without breaking the flow of combat.
- Prioritize her Battle Skill and Combo Skill upgrades for better debuffs; keep Basic Attack at base level.
Strengths
- Reliable healing through controllable Shadow pickups, with scaling based on Will.
- Can apply both Corrosion and Physical/Arts Susceptibility, amplifying team damage.
- Extremely flexible: fits as a healer, debuffer, or damage-amp support.
- Synergizes with many team compositions thanks to healing and debuffs.
Weaknesses
- Her heal relies on the controlled operator picking up Shadows, which can be awkward in fast fights.
- The LYNX set's DMG Reduction does not trigger from shared healing (e.g., Survive the Gas stage effect).
- Reroll rating is low (B), so she may not be a priority for players resetting at launch.
Team Guide
f2pf2pbeginnerlow_investment
A budget-friendly lineup where Ardelia keeps the squad alive and boosts both Physical and Arts damage. Corrosion and Susceptibility from Ardelia set up Endministrator's heavy hits, while Akekuri and Chen Qianyu keep the debuff loop flowing.
Explanation
Ardelia acts as a sustain and buffer, letting the team survive tough fights while improving the carry's damage output.
Using her Combo Skill to apply Corrosion and then consuming it with her Battle Skill triggers the skill twice and extends more healing support.
The Corrosion application also reduces enemy resistances, making Physical and Arts attackers like Endministrator more effective.
Chen Qianyu adds a Vulnerability stack when Endministrator acts, multiplying the follow-up damage.
Akekuri's SP recovery on staggered or stunned enemies helps the rotation start again faster.
Strengths
- Very cheap to build with free or easily obtained characters.
- Excellent survivability and consistent debuff uptime.
- Works well for clearing story content and early endgame stages.
Weaknesses
- Damage ceiling is lower than premium generalist setups.
- Rotation depends on enemies being stunned or staggered for full SP refunds.
- Ardelia needs her combo loop intact to maximize healing and debuffs.
Rotation
- 1Build up to Endministrator's Final Strike with basic attacks, which triggers Ardelia's Combo Skill and applies Corrosion to the target.
- 2Swipe the enemy with Ardelia's Battle Skill to consume Corrosion, applying Physical and Arts Susceptibility and doubling the skill's effects.
- 3Use Endministrator's Ultimate to shatter the crystal, or fall back on their Battle Skill, to prompt Chen Qianyu's Combo Skill and grant a Vulnerability stack.
- 4Land Endministrator's Battle Skill to consume the Vulnerability stack, then repeat the loop from step 1.
- 5When an enemy is stunned or staggered, activate Akekuri's Combo Skill or Ultimate to restore SP and accelerate the next rotation.
Basic attack to Final Strike → Ardelia Combo → Ardelia Battle → Endministrator Ultimate/Battle → Chen Combo → Endministrator Battle. Use Akekuri on staggered enemies to refund SP.
alternativegeneralistheat_team
A versatile Heat-oriented setup that leans on Ardelia to sustain and debuff while Laevatain deals the heavy damage. Wulfgard chips in as a secondary threat and Akekuri maintains SP to keep Ardelia’s Corrosion loop going.
Explanation
Ardelia's Corrosion weakens enemy resistance, letting Laevatain's Fire skills land much harder.
Wulfgard provides steady sub-DPS pressure between Ardelia's support windows.
Akekuri's SP refunds on stunned enemies allow Ardelia to cycle her debuffs more often.
This generalist shell can be adapted to different elemental carries depending on available units.
Strengths
- Strong single-target damage amplification via Susceptibility.
- Flexible sustain role that fits many content types.
- Akekuri keeps the rotation smooth when enemies can be staggered.
Weaknesses
- Requires investment in multiple characters to shine.
- Laevatain is a high-rarity unit not available to all players.
alternativegeneralistcryo_team
A Cryo-flavored variant where Ardelia supports Avywenna's damage with Corrosion and Susceptibility, while Perlica adds off-field damage and Arclight provides utility. This setup showcases Ardelia's flexibility as a universal support.
Explanation
Ardelia's debuffs help Avywenna's Cryo attacks bypass enemy resistance.
Perlica's sub-DPS role keeps pressure up while the main combo is on cooldown.
Arclight's support utility protects the team or sets up reactions.
This lineup demonstrates that Ardelia can enable Cryo-focused carries without losing her sustain identity.
Strengths
- Good mix of sustained damage and defense.
- Ardelia's healing keeps fragile Cryo units safer.
- Elemental coverage fits Cryo teams well.
Weaknesses
- Avywenna may require specific gear to reach her damage potential.
- Less bursty than hybrid teams built around Endministrator.
alternativegeneralistelectric_team
An Electric-oriented composition with Ardelia as the sustain backbone. Yvonne serves as the main carry while Alesh and Xaihi supply secondary damage and utility, and Ardelia's Corrosion keeps enemy resistances low for the whole squad.
Explanation
Ardelia's Susceptibility debuff improves both physical and electric damage from Yvonne and Alesh.
Xaihi's support role rounds out the team, contributing to SP or reaction synergy.
Alesh acts as an off-DPS that benefits from the same corrosion window.
This is another example of Ardelia being slotted into different elemental team archetypes.
Strengths
- Strong elemental synergy and flexible support.
- Ardelia's durability lets the team take longer fights.
- Good for content weak to Electric damage.
Weaknesses
- Requires Yvonne and Xaihi to be built well for competitive damage.
- No dedicated shielder; relies on Ardelia's healing.
alternativegeneralisthybrid_team
A hybrid team that uses Ardelia's Corrosion to trigger Gilberta's Combo Skill, granting free Vulnerable stacks without SP. Those stacks are then consumed by Endministrator or Mi Fu for Crush, making this a very explosive burst composition.
Explanation
Ardelia's Corrosion doubles as a trigger for Gilberta's Combo Skill, creating a Vulnerable stack with no SP cost.
Rossi can immediately use those stacks to activate his skills, or the team can save them for the main carry.
Endministrator or Mi Fu act as the main damage dealer, consuming the Vulnerable stacks for Crush.
This shows how Ardelia can enable hybrid reaction setups beyond simple elemental teams.
Strengths
- Very high burst potential thanks to free Vulnerable stacks.
- Can adapt the carry slot between Endministrator and Mi Fu.
- Ardelia provides both sustain and reaction enabler in one slot.
Weaknesses
- Requires precise execution to layer Corrosion, Vulnerable, and the carry's skill.
- Gilberta and Rossi need investment to make the combo feel smooth.
- If Ardelia's Corrosion is consumed by the wrong skill, the burst window is wasted.
Team Insights
Ardelia is a rare sustain/support hybrid who can fit almost any lineup. Her kit revolves around applying Corrosion with Combo Skill, consuming it with Battle Skill to trigger twice, and spreading Susceptibility while summoning healing sheep. Teams should be built around one strong carry that can eat the debuffs, plus supports that keep SP flowing or add extra Vulnerability stacks. Because Corrosion also interacts with reactions like Gilberta's Combo Skill, she is valuable in hybrid setups as well as classic elemental teams.
Synergy Patterns
- Ardelia + Endministrator: Corrosion and Susceptibility from Ardelia set up Endministrator's Final Strike and Combo Skill for huge damage.
- Ardelia + Chen Qianyu: Chen's Combo Skill layers a Vulnerability stack when the carry acts, stacking with Ardelia's debuffs.
- Ardelia + Gilberta: Corrosion can overload Gilberta's Combo Skill, granting a free Vulnerable stack without spending SP.
- Ardelia + Akekuri: SP restoration from Akekuri keeps the Corrosion-to-Susceptibility loop going more frequently.
Tips
- Always try to chain Ardelia's Combo Skill into her Battle Skill so the Battle Skill triggers twice and heals more.
- Save Ardelia's Ultimate for crowded waves to apply wide-area Corrosion and maximize healing.
- Use Akekuri's SP refund the moment an enemy is stunned or staggered, rather than holding it.
- Pair Ardelia with at least one burst carry that can consume Susceptibility or Vulnerability for best results.
