Weapon Choices for Ardelia

Dreams of the Starry Beach (Top Pick)

Ardelia’s signature weapon deserves the top spot, and here’s the best part—it’s completely free to obtain. This 6-star Arts Unit delivers exactly what Ardelia needs: Intellect, Will, and Treatment Bonus to boost her healing output.

The real magic happens when you trigger her Battle Skill. Each time Ardelia consumes Corrosion (which her kit does naturally), Dreams of the Starry Beach dramatically increases the Arts damage enemies take. This amplification effect transforms Ardelia from a pure healer into a genuine force multiplier for your damage dealers. Since this weapon aligns perfectly with her playstyle and costs nothing, there’s no reason not to use it.

Stanza of Memorials (Alternative Option)

If you’re still working toward her signature weapon or want to experiment with different playstyles, Stanza of Memorials serves as a solid backup. This 5-star option grants Intellect, ATK%, and HP%—keeping Ardelia’s personal stats healthy while adding team utility.

The standout feature here is the ATK% buff it provides to your entire squad while Ardelia channels her Ultimate. Since this build emphasizes frequent Ultimate usage anyway (more on that below), Stanza of Memorials synergizes well with the overall strategy. You’ll sacrifice some personal debuffing power compared to Dreams of the Starry Beach, but gain more consistent team damage output.

Gear Set and Equipment

Eternal Xiranite Set (Core Build)

Ardelia’s gear setup practically writes itself—the Eternal Xiranite set is the clear winner. This set activates whenever you apply susceptibility debuffs to enemies, which happens constantly thanks to Ardelia’s Battle Skill converting Corrosion into Physical and Arts Susceptibility.

Here’s what you need:

Eternal Xiranite Gloves T1 These gloves deliver the perfect stat combination: Intellect and Will (Ardelia’s primary and secondary stats) plus Ultimate Gain Efficiency. All three stats work together to boost her healing potency while letting her cast Ultimate more frequently.

Eternal Xiranite Auxiliary Arm (x2) Since Auxiliary Arms fall under the Kit gear category, you can equip two of them without breaking set bonuses. Each one provides Will, Intellect, and Ultimate Gain Efficiency. Running two copies completes your 4-piece Eternal Xiranite set while maximizing the stats Ardelia cares about most.

Flex Gear Option

Tide Fall Light Armor For your remaining gear slot, Tide Fall Light Armor gives you a substantial Intellect boost alongside extra Ultimate Gain Efficiency. It won’t interfere with your Eternal Xiranite set bonus, and the added stats make Ardelia’s healing even more impactful.

Stat Priority Breakdown

Focus on these stats when rolling or upgrading gear:

Intellect (Highest Priority) This primary stat directly scales Ardelia’s healing output. More Intellect means bigger heals and better sustainability for your team during extended fights.

Will (Secondary Priority) Ardelia’s secondary stat further amplifies her supportive capabilities. While not quite as impactful as Intellect, Will still contributes meaningfully to her overall effectiveness.

Ultimate Gain Efficiency (Essential) Ardelia’s Ultimate provides crucial healing during critical moments. Building Ultimate Gain Efficiency lets you access that healing more often, keeping your team topped off through sustained damage phases. Given how central her Ultimate is to this build strategy, prioritize this stat heavily on your gear pieces.

Playing Ardelia Effectively

Ardelia’s rotation is straightforward, which lets you focus on positioning and timing rather than complex combos. Use her Battle Skill regularly to convert Corrosion into susceptibility debuffs—this simultaneously weakens enemies for your damage dealers while activating your Eternal Xiranite set bonus.

Cast her Ultimate whenever it’s available to keep your team healthy. With high Ultimate Gain Efficiency, you’ll have access to this healing frequently enough to handle most threatening situations.

The key to mastering Ardelia is recognizing when to prioritize healing versus debuffing. During high incoming damage phases, save your Ultimate for emergency recovery. When your team is stable, focus on maintaining debuffs to accelerate clear times.
