If you're planning your long-term roster in Endfield, you'll notice pretty quickly that Ardelia isn't just "nice to have"—she's the sort of free pickup that changes how you build teams. People even reroll their plans around her, especially if they're also looking at Arknights endfield accounts to start with a cleaner lineup. She's a 6-star Nature Supporter you get by simply showing up, and that still feels a bit wild. In most gacha games, the freebie is a placeholder. With Ardelia, you're getting a real endgame piece that keeps paying you back as fights get longer and messier.

How Her Loop Actually Works

Her value lives in the rhythm, not in a single button. You want an ally to land a Final Strike on a target that doesn't already have Arts Infliction or Vulnerability. That's the trigger. Ardelia's Combo Skill drops Corrosion, and you can treat it like a "setup" layer that starts shaving down what the enemy can normally shrug off. Then you press your advantage: use her Battle Skill to consume Corrosion and flip it into Physical and Arts Susceptibility. That's when the boss health bar starts moving in a way you can feel. Miss the timing and it's still fine, but it's not the same kind of swing.

Healing That Doesn't Kill Your Damage

What's sneaky about her kit is how much safety you get without swapping gears. Between Friendly Presence and her Ultimate, she leaves behind those little shadows of Mr. Dolly that act like healing lanes. In practice, you're not "pausing" to play medic. You're kiting through a zone, your active operator tops off, and your low-HP teammate stops flirting with disaster. It's especially noticeable on marathon bosses where mistakes stack up. Ardelia lets you recover while you're still doing the thing you came to do: set debuffs and keep pressure on.

Weapons, Stats, and Team Fits

If you can get her signature weapon, Dreams of the Starry Beach, do it. The Intellect bump and healing efficiency are obvious wins, but the extra Arts damage debuff is what keeps her ceiling high. If you don't have it, don't overthink it—aim for Will and Intellect on whatever you can equip, because that's what her heals and debuff strength care about. Team-wise, she's weirdly universal. Heat squads love her because Susceptibility makes every burn window hit harder. Cryo teams like the way she turns controlled uptime into real damage. Even physical-focused comps still benefit, since she isn't picky about where the damage comes from.

Making Her Feel Effortless

The best advice is simple: don't spam her buttons just because they're up. Watch for that clean Final Strike moment, tag the target, then cash in Corrosion when your team's ready to unload. After a few runs, it becomes muscle memory, and that's when Ardelia starts feeling "unfair" in a good way. If you're the kind of player who likes to speed up progression, grab missing mats, or smooth out gearing headaches, it also makes sense to use U4GM for game currency or items so your squads come online faster without waiting on perfect drops.
