| Arknights: Endfield Ardelia Best Weapons
Dreams of the Starry Beach
Dreams of the Starry Beach serves as Ardelia's Signature Weapon. It significantly enhances her HP Treatment output to ensure team survivability, while further amplifying her utility in Arts damage focused squads. When Ardelia consumes Corrosion on a target using her Battle Skill, enemies will suffer increased damage. However, please note a key limitation: this weapon provides no tactical advantage when supporting Physical damage teams.
Monaihe
If you haven't acquired her Signature Arts Unit, Monaihe serves as a solid alternative. It focuses entirely on enhancing the wielder's Attributes rather than offering a Conditional Bonus Effect.
- Willpower +124 (9/9)
- Ultimate Gain Efficiency +37.14% (9/9)
Inspiring: Mortise-and-Tenon Analysis (9/9):
Main Attribute +14%.
Arts Intensity +70.
Stanza of Memorials
Stanza of Memorials serves as Ardelia’s optimal weapon choice when she is slotted into Physical-attribute team comps, primarily because her signature equipment lacks synergy outside of its native element.
This weapon provides solid base attributes for her kit, but its true value lies in its passive: whenever Ardelia triggers her Ultimate, it grants a significant, long-lasting ATK buff to all allied operators who do not possess the Nature attribute.

Eternal Xiranite
Equipping the Eternal Xiranite set allows Ardelia to cast her Ultimate more frequently. It also synergizes with her Battle Skill, boosting the team's ATK every time she applies the Susceptibility debuff.


| Arknights Endfield Ardelia Best Team Comps
Ardelia is one of the most versatile Supporters in the game, seamlessly fitting into almost any squad. Her only notable anti-synergy is with teams that maintain lingering Inflictions, which can hinder the execution of her Combo Skill. Aside from this, she excels in Physical damage compositions or teams leveraging her Corrosion effects. As a free Operator, she is a go-to option for any Administrator needing reliable HP Treatment.
Team 1
Team 2

Team 3
Team 4
| How to Play Ardelia
Ardelia's kit is built around a dual focus: providing HP Treatment through healing zones and amplifying team damage via a strict Corrosion loop. Her gameplay revolves on applying Corrosion with her Combo Skill and immediately consuming it with her Battle Skill to inflict a potent, 30-second Arts and Physical Susceptibility debuff on the target.
However, proper timing is essential. Her Combo Skill—which attaches a delayed bomb to the enemy—only triggers when the Controlled Operator lands a Final Strike on a target free of any Arts Inflictions or Vulnerability stacks. You must initiate combat with a Final Strike and carefully watch for "clean windows" when enemy debuffs expire to re-trigger this combo.
For survival, her Ultimate summons copies of Mr. Dolly. Players can collect the resulting Shadows of Mr. Dolly with the Controlled Operator to heal themselves or the teammate with the lowest health percentage.

| Arknights: Endfield Ardelia Trivia
Ardelia's memory archetype is rooted in Eyjafjalla, known as the "Little Sheep" from Arknights. Unlike the distinct separation seen between Lavantine and Surtr, Ardelia inherits a significant portion of Eyjafjalla’s persona. She possesses a profound empathy for her predecessor's past suffering, effectively serving as another manifestation of Eyjafjalla on Talos-II.
One ordinary day, Ardelia encountered the Lord of Sheep, Mr. Dolly. Mischievous and affectionate, Mr. Dolly is deeply attached to her and often finds ways to help her relax when she feels busy or anxious. Having had her body reshaped by Originium, Ardelia is no longer an Infected; she can now clearly hear the voices of life across the land and deeply cherishes this liberation from the torment of Oripathy.
Heavily influenced by Eyjafjalla’s memories, her passion lies in volcanic geological research. Unlike Eyjafjalla during the Terra era, who required accompaniment for data collection, Ardelia is now capable of conducting such field research independently and exceptionally.
