supportsustaindebuffhealer
Ardelia is a versatile Nature-element sustain character providing healing and powerful debuffs. She applies Corrosion to reduce enemy resistance, then triggers Physical and Arts Susceptibility to amplify team damage. Her healing scales with Will and is activated by collecting Shadows of Mr. Dolly, spawned by her Battle Skill and Ultimate. This dual role makes her valuable, though healing requires active pickup mechanics and Corrosion management.
endgame support late_gamedebuffteam_buffsustain
This endgame support build maximizes Ardelia's debuffing and team‑buffing capabilities. The combination of Dreams of the Starry Beach and Eternal Xiranite set allows her to apply Corrosion and Susceptibility while simultaneously granting allies a damage boost and benefiting from increased healing. High Will and Intellect from gear pieces further reinforce her sustain, and ultimate gain efficiency keeps her ultimate ready for emergency heals and additional Shadow of Mr. Dolly spawns. This build is ideal for players who want Ardelia to function as a primary sustain with strong offensive utility.

Explanation
Dreams of the Starry Beach enhances debuffing by increasing Arts DMG taken after consuming Corrosion, and its Treatment Efficiency Boost improves healing.
Stanza of Memorials offers a team‑wide ATK boost on ultimate cast and a Max HP increase, making it a solid alternative if you prioritize team buffs over personal healing.
Monaihe accelerates ultimate recharge, enabling more frequent healing and corrosion application. Fluorescent Roc is a serviceable early‑game option that boosts Will and ATK.
Eternal Xiranite perfectly complements her playstyle: after applying Physical/Arts Susceptibility, the entire team gains a 16% DMG buff for 15s, turning her debuff into a team‑wide amplifier.
Notes
- Focuses on amplifying team damage through debuffs and the Eternal Xiranite set's team‑wide DMG+16% when Susceptibility is applied.
- Will remains important for healing, but the primary goal is to cycle Dolly Rush and Eruption Column for constant debuffs.
- Ultimate Gain from gear pieces helps charge Wooly Party for more frequent healing and Shadow of Mr. Dolly generation.
endgame support late_gamepure_healersurvivabilityfocused_healing
This build focuses exclusively on maximizing Ardelia's healing potential. With the LYNX gear set and a weapon that boosts Treatment Efficiency, she can keep the entire team alive even in high‑damage encounters. The DMG Reduction buff further protects allies after receiving heals. While it sacrifices some of the team damage amplification of the Eternal Xiranite build, it excels in content where survival is the main challenge. Use Chivalric Virtues if you still want to contribute some ATK buffs while healing.

Explanation
Dreams of the Starry Beach remains the best weapon because it provides both healing improvement and an Arts DMG taken debuff, giving the healer build some offensive utility.
Chivalric Virtues offers a team‑wide ATK buff after healing, useful when healing is already sufficient but you want more damage.
Freedom to Proselytize adds a secondary heal when using the battle skill, making it a strong low‑rarity option for pure healing.
The LYNX set is chosen over Eternal Xiranite when survivability is the top priority; the DMG Reduction can prevent one‑shots and ease pressure on the team.
Notes
- The LYNX set grants +20% Treatment Efficiency and applies DMG Reduction to healed allies, greatly improving team survivability.
- Healing output scales heavily with Will, so will_boost and treatment_efficiency are the highest priorities.
- The LYNX set effect does not trigger on non‑controlled allies or from shared healing effects like in the Survive the Gas stage.
early game support beginnerf2psustainearly_heal
The early game build focuses on affordability and straightforward healing. Freedom to Proselytize and the Mordvolt Resistant set provide enough Will and Treatment Bonus to keep the team alive through the early and mid‑game. While it lacks the advanced team buffs of late‑game builds, it ensures that Ardelia can fulfill her sustain role from the start.

Explanation
Freedom to Proselytize is the best early weapon because it directly boosts Will and adds a secondary heal on battle skill use, greatly improving sustain.
Fluorescent Roc is a fallback that provides Will and ATK but lacks the extra healing of Freedom to Proselytize.
Mordvolt Resistant gear is accessible and gives a mix of Will, Intellect, and Treatment Bonus, which are exactly the stats Ardelia needs to heal effectively.
Notes
- This build uses easily obtainable gear and a 4‑star weapon to provide solid healing early on.
- High Will from the Mordvolt Resistant set increases both healing and treatment bonuses from the battery pieces.
- The set effect grants extra Treatment Effect when HP is below 50%, helping in clutch situations.
Build Insights
Ardelia operates as a dedicated sustain unit with a strong debuffing niche. She fits into most team compositions that need healing and want to bypass enemy resistances. Her Corrosion reduces all elemental resistances, setting up follow‑up damage from any element. She synergizes well with characters who trigger her Combo Skill via Final Strikes, and with teams that lack other sources of Physical/Arts Susceptibility. The Eternal Xiranite gear set turns her debuff application into a team‑wide DMG buff, cementing her as a high‑value support in endgame content. In short, she is a plug‑and‑play healer/debuffer that enhances overall team damage while keeping allies alive.
Core Mechanics
- Combo Skill Eruption Column applies Corrosion to enemies, reducing their elemental resistance. The Battle Skill Dolly Rush consumes Corrosion to apply Physical and Arts Susceptibility, increasing damage taken by enemies.
- Talent Friendly Presence spawns Shadows of Mr. Dolly when Dolly Rush hits or during Ultimate, which heal the controlled operator (and lowest-HP teammate) when touched. Healing scales with Will.
- Talent Mountainpeak Surfer allows Dolly Rush to be cast again for free if an enemy with Corrosion is nearby, effectively doubling its debuff and healing output.
- Ultimate Wooly Party summons multiple sheep that deal area Nature damage and have a chance to create Shadows of Mr. Dolly for additional healing.
Scaling
- Healing scales with Will, making will_boost and treatment_efficiency stats high priority. Intellect provides minor damage scaling but is not a primary focus.
- Debuffs like Corrosion and Susceptibility have fixed percentages and durations; they do not scale with stats, so Ardelia's effectiveness as a debuffer is gear‑independent.
- Team damage amplification from weapons and gear (e.g., Dreams of the Starry Beach, Eternal Xiranite set) scales with gear quality, making late‑game investment significant.
- Early game she is already a capable healer with Freedom to Proselytize and Mordvolt Resistant set; her utility grows with better weapons and gear.
Character Notes
Ardelia is a Nature‑element Supporter who fills the sustain role by healing allies and debuffing enemies. She applies Corrosion with her Combo Skill to reduce enemy resistances, then consumes it with her Battle Skill to inflict Physical and Arts Susceptibility, increasing all damage taken by the target. Her Talent creates Shadows of Mr. Dolly that heal the controlled operator when touched, and she can also heal a low‑HP teammate simultaneously with potential upgrades. Ardelia’s versatility makes her a staple in many team comps, offering both survivability and damage amplification through her debuffs and gear effects.
Playstyle
- Start encounters by triggering Eruption Column via a Final Strike to apply Corrosion. Then use Dolly Rush to consume the Corrosion and apply Susceptibility. The free recast from Mountainpeak Surfer will trigger if Corrosion is still present, doubling your debuff application and healing shadows spawned.
- Use Wooly Party when the team needs quick healing or to generate multiple Shadows of Mr. Dolly. Move the controlled operator over the shadows to pick them up and heal.
- Position Ardelia in a team slot that can easily trigger her Combo Skill (characters with Final Strike mechanics). She works well as a secondary support or main healer depending on the encounter.
Strengths
- Provides both healing and debuffs, reducing the need for a dedicated healer and a dedicated debuffer.
- Corrosion reduces all elemental resistances, making her an excellent amplifier for any elemental team.
- Her talent-based healing allows her to sustain without spending active skill time, and the free recast of Dolly Rush adds significant value.
- Endgame gear sets (Eternal Xiranite, LYNX) drastically improve her team utility, either buffing team damage or further enhancing survival.
Weaknesses
- Healing requires the controlled operator to physically touch Shadows of Mr. Dolly, which can be awkward during intense combat or when positioning is limited.
- LYNX set's DMG Reduction does not trigger from shared healing effects, limiting its usefulness in certain stages.
- Relies on the Corrosion mechanic for debuffing; if Corrosion application is interrupted or enemies become immune, her debuff loop is disrupted.
- Lower base stats than dedicated healers; her healing output is heavily dependent on Will investment and gear.
Team Guide
f2p f2pbeginner
This budget-friendly team relies on Ardelia's sustain and debuffing to boost Endministrator's damage. Ardelia applies Corrosion with her Combo Skill, then consumes it via Battle Skill to inflict Physical and Arts Susceptibility, increasing all incoming damage. Akekuri and Chen Qianyu provide additional support and SP regeneration, enabling a smooth rotation. The team excels in prolonged fights where consistent debuff uptime and healing keep the party alive while Endministrator unleashes heavy attacks. It's accessible for free-to-play players using easily obtainable characters.
Explanation
Ardelia's Combo Skill applies Corrosion, reducing enemy resistances, and her Battle Skill consumes it to apply Physical and Arts Susceptibility, amplifying the team's damage.
Endministrator serves as the main DPS, and the rotation cycles through Final Strike, Combo Skills, and Battle Skills to keep debuffs active.
Akekuri can restore SP with her Combo Skill when enemies are stunned or staggered, helping to loop rotations faster, while Chen Qianyu adds Vulnerability.
Strengths
- Low character investment required; all members are accessible.
- Strong debuff uptime with Corrosion and Susceptibility boosts overall damage.
- Reliable healing from Ardelia's Battle Skill sheep keeps the team healthy.
Weaknesses
- Rotation-dependent; missing skill timings reduces damage output significantly.
- Lacks crowd control outside of stuns from Chen's Ultimate.
- Against highly mobile enemies, applying Corrosion consistently can be tricky.
Rotation
- 1 Use Endministrator's basic attacks until Final Strike to trigger Ardelia's Combo Skill, applying
Corrosion and activating Endministrator's own Combo Skill as a follow-up. - 2 Activate Ardelia's Battle Skill to consume the
Corrosion , inflicting Physical and Arts Susceptibility which amplifies all incoming damage. - 3 If available, unleash Endministrator's Ultimate to detonate the crystal; otherwise use their Battle Skill. This will trigger Chen Qianyu's Combo Skill and apply a stack of Vulnerability.
- 4 Use Endministrator's Battle Skill again to consume the Vulnerability, then repeat the cycle from Step 1.
- 5 When the enemy is stunned or staggered, use Akekuri's Combo Skill to restore SP, and her Ultimate if ready to further replenish skill points.
Apply Corrosion with Ardelia's Combo Skill, consume it with Battle Skill for susceptibility, then unleash Endministrator's damage while weaving in support from Chen and Akekuri.
elemental heat_teamelemental
In this Heat-focused variant, Ardelia provides sustain while Wulfgard and Akekuri stack Heat Infliction to fuel Laevatain's Melting Flame stacks.

Team Insights
Ardelia excels as a flexible sustain character who can slot into any team thanks to her Corrosion application and healing. Her primary role is to debuff enemies by applying Physical and Arts Susceptibility after consuming Corrosion, which significantly increases the entire team's damage output. She synergizes particularly well with DPS units that benefit from reduced enemy resistances, and her healing mechanic via Battle Skill ensures party survivability. Optimal rotations involve coordinating her Combo and Battle Skills with the team's burst windows, often using Endministrator as a trigger for additional combos. Pair her with SP regeneration supports to maintain debuff uptime.
Synergy Patterns
- Ardelia's Combo Skill applies Corrosion when triggered by an ally's Final Strike, making her a natural partner for characters like Endministrator who frequently use normal attack chains.
- Her Battle Skill not only heals but also consumes Corrosion to double its damage and apply Physical and Arts Susceptibility, amplifying the damage of subsequent attacks from all allies.
- Combining with Akekuri provides SP recovery when enemies are debuffed, ensuring faster rotation cycles.
- In elemental teams, her debuffs stack with elemental status effects to maximize reaction damage.
Tips
- Always apply Corrosion before using Ardelia's Battle Skill to trigger the double hit and susceptibility debuff.
- Coordinate her Combo Skill with an ally's Final Strike to immediately trigger the chain.
- Save her Ultimate for emergency healing or to extend susceptibility duration during critical burst phases.
- In teams with Akekuri, try to time Ardelia's debuff application just before using Akekuri's SP regeneration skills to gain maximum benefit.
