Who is Arknights Endfield Ardelia?
Ardelia is a 6 star Supporter who deals Arts damage and focuses on Nature element effects. She works as a geologist for Rhodes Island and Endfield Industries, using an Orbiter weapon to attack enemies from range. Her role is not limited to damage alone. The kit is built around keeping the team alive, weakening enemies, and boosting overall performance during fights.
Ardelia’s support comes from a mix of mobile healing, enemy debuffs, and teamwide buffs. Power scaling mainly depends on Intellect, which improves attack strength, and Will, which increases healing output. This makes her effective even without heavy investment early on.

Ardelia Skills & Talents Breakdown
A perfect Arknights Endfield Ardelia build evolves around applying Corrosion and then consuming it to weaken enemies. Corrosion is applied through her Combo skill, then triggered using her Battle skill to create Susceptibility. This increases both Physical and Arts damage enemies take, ranging from 12 to 20%, and lasts for 30 seconds. Talents enhance this loop by allowing extra Battle casts and generating healing effects at the same time.
Once this cycle is understood, the rest of her kit flows naturally during combat so here is how her combat skills work:
|
Skill |
Key Effect |
Max Multiplier |
|
Rocky Whispers |
This is a four hit sequence dealing Nature damage. The final strike applies 18 Stagger, while diving attacks deal area damage. If the target is already staggered, the finisher restores skill points. |
At full effect, the finisher reaches up to 900% damage |
|
Dolly Rush |
This skill costs 100 SP and charges forward to deal Nature damage while applying 10 Stagger. If Corrosion is present on the enemy, it gets consumed and turns into Physical and Arts Susceptibility. |
Maximum damage reaches 320%, making it the core trigger in her setup. |
|
Eruption Column |
This skill has an 18 second cooldown and activates when a final strike hits an enemy that has no existing vulnerability or Arts effects. It creates a cloud that explodes shortly after, applying temporary Corrosion. |
Explosion damage reaches 250%, setting up the next Battle skill use. |
|
Wooly Party |
The Ultimate has a 90 cost and a 15 second cooldown. During the channel, Ardelia throws dollies that hit each enemy once every 0.3 seconds, dealing Nature damage and adding 2 to 3 Stagger per hit. |
Total damage scales up to 165% over the channel duration. |
Talents
-
Friendly Presence (Priority 1): Using a Battle or Ultimate skill summons shadow units. When these shadows touch allies, they heal for 90 plus 0.75 times Will. If Ardelia is at full health, healing targets the lowest HP ally instead. Up to 10 shadows can exist at once, each lasting 10 seconds.
-
Mountainpeak Surfer (Priority 2): When a Corrosion affected enemy is hit by the Battle skill, the skill automatically triggers one additional free cast. This greatly improves Susceptibility uptime without extra resource cost.
-
Keen Mind: Unlocking Promotion IV grants a flat bonus of 20 Intellect, improving both damage contribution and scaling efficiency.
Potentials: Potential for Arknights Endfield Ardelia build levels from P1 to P5 further strengthen Ardelia’s support role. These upgrades increase Susceptibility values by up to 8%, improve healing output, and reduce Ultimate cost, duration, or cooldown depending on the potential level.
Arknights Endfield Ardelia Best Weapons
When going for an Arknights Endfield Ardelia best build, don’t forget about your weapon choices. Arknights Endfield Ardeila build needs to be done by prioritizing Will for heals, then Infliction/Treatment Efficiency. And if you want the best choices of weapons, these are what we recommend:
|
Weapon |
Why? |
Essence Priority |
|
Dreams of the Starry Beach (Sig, Free) |
This is Ardelia’s signature weapon and is available for free, making it the strongest and most accessible option. It provides a strong boost to Will and healing output. When Corrosion is consumed, enemies take an additional 16% Arts damage for 25 seconds. This effect fits perfectly into her natural playstyle and requires no extra effort to maintain. |
Will > Infliction |
|
Monaihe |
This weapon increases Will and improves Ultimate energy gain. It also enhances Arts intensity, which benefits both her damage and healing scaling. It performs well in longer fights where the Ultimate is used often and offers stable value without relying on Corrosion triggers. |
Will > Ult Gain |
|
Stanza of Memorials |
Designed more for team support, this weapon provides a teamwide attack buff along with increased maximum HP. While it does not directly boost Corrosion effects, it improves overall team durability and damage output. It works best in balanced or mixed-element teams. |
Will > ATK |
|
Freedom to Proselytize (Early) |
This is a solid early-game option for players who lack higher-tier weapons. It increases Will and healing output while offering additional ally healing. Although it falls off later, it remains useful during progression and early content. |
Will |
Best Gear Sets & Stat Priority
Gear selection can define how powerful you can make an Arknights: Endfield Ardelia build to perform better in long fights. This is specifically helpful in supporting for elemental or mixed teams. If you want the best gear sets and stats for her, remember the ultimate goal should be to improve the damage scaling and then rotation speed.
So, here are our best recommended gear sets for an Arknights: Endfield Ardelia build:
-
Endgame Setup: The best late-game option is the Eternal Xiranite 3 piece set. This set grants 1000 bonus HP and triggers a teamwide damage increase of 16% for 15 seconds when Susceptibility is applied. It fits naturally with Ardelia’s Corrosion and Susceptibility loop. Remaining slots can be filled with Tide Surge pieces to secure better substats and flexibility.
-
Early Game Setup: For early progression, Mordvolt Resistant works well. It provides 50 Will and increases Treatment by 30% when HP is low. This helps stabilize teams when gear and levels are still limited.
Multi-instance & Sync: Operate multiple accounts simultaneously to improve rerolling efficiency
One-key Macro：Record and auto-execute your actions, making resource farming and dungeon clearing a breeze
High FPS & Keyboard Mapping：Smoother combat, precise skill activation, and no lag or frame drops
Video Recorder：Record highlights and turn them into shareable videos
Stat Priority Order
Will should always come first, as it directly affects healing output and overall sustain. Intellect follows next, improving damage scaling and support effectiveness. Ultimate SP gain helps speed up rotations, allowing more frequent buffs and healing. HP and Treatment modifiers come last, adding extra survivability without being the main focus.
Priority order here should be as follows:
-
Will
-
Intellect
-
Ultimate SP gain
-
HP and Treatment modifiers
Endgame Gear Slot Suggestions
-
Body slot works best with a Tide Surge off piece
-
Gloves should use Eternal Xiranite Tier 1
-
Kit slots one and two should be filled with Eternal Xiranite auxiliary arms
This setup keeps the core set bonus active while allowing room for strong secondary stats.
Upgrade & Skill Priority
-
Ascend to E4 (full talents).
-
Skills: Battle (M9) > Combo/Ult (M7) > Basic (M1-3).
-
Potentials: P1 (Susc+), P2 (Extra heal).
-
Weapon/Gear: Sig first, then Xiranite farm.
F2P Path: For free to play players, reaching Battle skill M7 and equipping the signature weapon already unlocks around 90% of her practical potential. This makes Ardelia very efficient to build without heavy resource investment.
Best Ardelia Teams & Rotations
Next, we are going to pay attention to the Arknights Endfield Ardelia teams. She can be slotted as Sustain/Support in any comp because Ardelia boosts Phys/Arts universally.
And these are your best teams to go with:
|
Team Type |
Comp |
Role/Synergy |
|
Heat |
Laevatain (DPS), Wulfgard/Akekuri (Inflict), Antal (Buffer) |

|
Cryo |
Last Rite (DPS), Xaihi (Stack), Perlica (Electrify) |
Corr shreds RES; Susc on Hypothermia pops. |
|
F2P |
Endministrator (DPS), Chen (Sub-DPS), Lifeng/Akekuri |
Free sustain; Endmin Final → Ardelia Combo loop. |
Core Rotation (15-20s cycle)
-
DPS Final Strike (clean enemy) → Ardelia Combo (Corr apply).
-
Ardelia Battle (consume → Susc + recast + 6 Shadows heal).
-
DPS Ult/Battle (amp'd damage).
-
Repeat; Ult on stagger/CDs.
Playstyle Tips & Strengths/Weaknesses
-
Tips: Start fights by clearing enemy debuffs so the Combo skill can trigger correctly. This ensures Corrosion is applied without interference. During combat, move through the Shadows she creates, as stepping on them activates healing. Positioning matters for the Battle skill since the ram attack needs proper alignment to hit enemies cleanly. She performs especially well in open-world content where boss fights last longer and sustained healing is more important than burst damage.
-
Strengths: Ardelia is a free unit that still holds a meta-level role, making her one of the safest long-term investments. Team building stays flexible since there is no element restriction. Buffs last up to 30 seconds and pair naturally with mobile healing, allowing smoother rotations. Scaling remains strong into endgame, even without heavy spending.
-
Weaknesses: The Combo skill requires setup, which can feel slow in fast-paced fights. Personal damage output stays low, as her role focuses on support rather than DPS. In mono-element teams, she often competes for the fourth slot, especially when stricter damage requirements exist.
People Also Ask
Is Ardelia worth pulling duplicates for?
Duplicate pulls are not necessary. The first potential unlock provides the most important Susceptibility increase. Additional copies mainly adjust Ultimate behavior and are considered luxury upgrades.
What module should I equip on Ardelia?
Modules that boost Will percentage or Treatment modifiers offer the most value. These directly improve Shadow healing without weakening her debuff focused playstyle.
Can Ardelia solo carry early bosses?
She shines at keeping teams alive but cannot handle bosses alone due to low damage. Pairing her with a strong DPS like Endministrator allows underleveled clears in Chapter 3 with steady sustain.
Conclusion
So, with that, our Arknights Endfield Ardelia build guide ends. If you want to maximize her power, these are the steps you need to go with. So, it is time to claim your Arknights Endfield codes and make the best of her performance for the gameplay.
