Ardelia shows up across Mi Fu, Zhuang Fangyi, Laevatain, Last Rite, and Yvonne teams as sustain-plus-amp — keeping Monument attempts alive while still contributing buff uptime, which is why she is not treated as a pure healer flex. Pull if your clears die to attrition before the carry’s second dump; skip if your account already runs a finished buffer line and never fails on survival.
Ardelia is a 6★ Nature Support (Arts Unit). What might look like a difficult kit at first, is actually quite simple.

What might look like a difficult kit at first, is actually quite simple.
Ardelia is built around providing HP Treatment to her teammates by spawning zones of Healing, which you can stepped into with the Controlled Operator to either heal themselves, or the most injured party member, if the Controlled Operator is at full health.
Use these notes as the operator priority order inside the comps above.

Intellect Boost [L] · Treatment Efficiency Boost [L]
Secondary attribute +16/28.8/44.8%. After the wielder consumes Corrosion, target enemy suffers Arts DMG Taken +10/18/28% for 25.00s. Effects of the same name cannot stack.
Why it works —Signature option. It dramatically increases her HP Treatment output, helping her keep your entire team healthy, while further boosting her usefulness for teams that deal a lot of Arts damage.

Will Boost [M] · Ultimate Gain Efficiency Boost [M]
Main Attribute +5/9/14%. Arts Intensity +25/45/70.
Why it works —If you don't have her signature Arts Units, Monaihe is a decent alternative that fully focuses on buffing the wielder's attributes instead of providing a conditional bonus effect.

Eternal Xiranite is Ardelia's BiS. Ultimate Gain Efficiency speeds up her Ult cycle, and Susceptibility from her Battle Skill triggers the team ATK/DMG buff so her support kit actually pays the squad.

Tide Surge is the Cryo-focused alternative. Stronger personal Arts Infliction payoff, weaker team amp than Eternal Xiranite.

Ardelia sustain seat on a Heat lane: Laevatain and Wulfgard own Combustion damage, Akekuri amps — Ardelia keeps them alive and Susceptibility-buffed.
Laevatain is a Heat Combustion carry. She detonates Combustion on demand — in Ardelia's team she is a dual-Heat damage partner, not a support.
Akekuri amps Ardelia's team off SP recovery — shorter Combo Skill cooldown and a team DMG buff so Ardelia's dump windows hit harder. She does not replace element enablers like Perlica.

Ardelia is the sustain-plus-amp seat — keep the squad alive and trigger Susceptibility amps when the carry is ready to dump.
Wulfgard applies and consumes Combustion for Heat damage. Next to Ardelia, he is a Heat damage partner who wants the same Combustion uptime.
BASIC ATTACK: An attack with up to 4 sequences that deals Nature DMG. As the controlled operator, Final Strike also deals 18 Stagger. DIVE ATTACK: Basic attack performed in mid-air becomes a dive attack that deals Nature DMG to nearby enemies. FINISHER: Basic attack performed near a Staggered enemy becomes a finisher that deals massive Nature DMG and recovers some SP.
SKILL DESCRIPTION: Hops on Mr. Dolly and rams the target to deal Nature DMG. If the target has Corrosion, then consume the Corrosion and apply Physical Susceptibility and Arts Susceptibility to the target.
COMBO TRIGGER: When the controlled operator performs a Final Strike on an enemy with no stacks of Vulnerability or Arts Infliction. SKILL DESCRIPTION: Launches a homing Volcanic Cloud at a target enemy that deals Nature DMG when close enough to the target. The Volcanic Cloud explodes after a short delay, dealing half of the Nature DMG and forcibly applying temporary Corrosion to nearby enemies.
SKILL DESCRIPTION: Ardelia enters a mobile channeling state and summons the aid of Mr. Dolly. Multiple copies of Mr. Dolly are thrown in random directions. Each copy deals Nature DMG when hitting the enemy. Each enemy can only take 1 damaging hit every 0.3s.
Operator Intellect +10. / Operator Intellect +15. / Operator Intellect +15. / Operator Intellect +20.
The battle skill Dolly Rush creates 3 Shadows of Mr. Dolly after hitting the enemy. The copies of Mr. Dolly scattered by the ultimate Wooly Party also have a 10% chance to create Shadows of Mr. Dolly when they fall to the ground. When the controlled operator touches a Shadow of Mr. Dolly, Ardelia restores the said operator's HP by [90 + Will×0.75]. If the controlled operator is already at max HP, then restore the HP of the teammate with lowest percentage HP. Shadows of Mr. Dolly last for 10s and up to 10 can exist in the battlefield.
Battle skill Dolly Rush improved: Triggering the additional effect while an enemy with Corrosion is nearby immediately casts the battle skill again. This effect can only trigger once per active battle skill casting.
Battle skill Dolly Rush improved: Consuming Corrosion now applies Physical Susceptibility and Arts Susceptibility with effects +8%.
