Best W-Engines

When you want to Build Astra Yao for maximum support, you should always look for W-Engines that boost her ATK and Energy Regen. These stats help her buff your team and keep her skills running smoothly. You need at least 3430 ATK to trigger her Core Skill buff at full strength. If you fall short, your team loses out on damage.

Here’s a quick look at the top W-Engines for Astra Yao:

W-Engine	Base ATK	Energy Regen	Extra Effect
Kaboom the Cannon	624	50%	Team ATK buff up to 16% when dealing damage
The Vault	624	50%	Boosts Ether DMG, more Energy Regen for Chain/Special Attacks
Elegant Vanity	713	—	30% ATK, squad DMG up to 20% on Energy use
Weeping Cradle	684	—	24% PEN Ratio, squad DMG boost after attack
Bashful Demon	624	—	25% ATK, Ice DMG up, squad ATK boost during EX Special Attack

Tip: Kaboom the Cannon and The Vault stand out for Astra Yao. Both give high ATK and Energy Regen, which means you can trigger her buffs more often and keep your team rolling. Elegant Vanity offers the highest base ATK, so if you want raw power, it’s a solid pick.

Skill Upgrade Priorities

If you want to Build Astra Yao for the best support, you need to upgrade her skills in the right order. Some skills help her deal damage, while others boost her ability to buff your team. Here’s a breakdown:

Skill Name	What It Does
Capriccio	Basic attack, Ether DMG, pulls enemies in for stronger hits
Interlude	Attacks in Idyllic Cadenza, triggers Quick Assist on hit
Chorus	Multi-hit attack, big Ether DMG, grants invulnerability during the skill
Finale	Ether DMG, exits Idyllic Cadenza, grants buff, allows follow-up attacks

You should focus on upgrading Chorus and Finale first. These skills let Astra Yao deal heavy Ether damage and give your team strong buffs. Interlude comes next, since Quick Assist helps with energy and combos. Capriccio is useful, but you can leave it for last if you want to save resources.

Note: Upgrading her support skills means you get more out of her buffs. Your team will hit harder and stay safer during tough fights.

Stat Optimization

To Build Astra Yao for her support role, you need to push her ATK and Energy Regen as high as possible. These stats make her buffs stronger and let her use skills more often. You should always check her ATK stat and make sure it’s above 3430. If you miss this mark, her Core Skill buff won’t reach its max potential.

Here’s what you should aim for:

• Main Stats: ATK%, Energy Regen, Ether DMG
• Substats: Flat ATK, ATK%, Energy Regen, PEN Ratio

You can use discs and substats to fill in the gaps. If you get lucky with rolls, you can push her ATK even higher. Energy Regen helps her cycle through skills and keep buffs up for your team. For more general advice on optimizing builds, check out our Game Guides.

Pro Tip: If you want to Build Astra Yao for top-tier support, always check your gear and swap out pieces that don’t boost ATK or Energy Regen. Small upgrades can make a big difference in your team’s damage.

Best Discs

Recommended 6-Piece Sets

Astral Voice (6-piece):

• 24% DMG boost, always active with Astra Yao’s playstyle.

If you do not have a full 6-piece Astral Voice set, you can mix and match two-piece sets for a 10% Attack boost. This still helps Astra Yao buff your team and keeps her support strong.

Set Synergy

The Astral Voice set works perfectly with Astra Yao’s abilities. She boosts her own and her allies’ attack power during states like Idyllic Cadenza. This means the set’s bonus gets used to the fullest, making your team hit harder. The two-piece set bonus gives a 10% Attack boost, which stacks with her buffs. The four-piece set adds a teamwide stacking damage buff during Quick Assists. This is huge for support, especially when you run Astra Yao with characters like Zhu Yuan who love extra Attack scaling.

Build Tips & Mistakes

Upgrade Priorities

You want to get the most out of Astra Yao’s support skills. Many players forget which skills matter most. If you want her to shine, focus on her Special Attack and Chain Attack first. These skills boost your team’s damage and keep buffs rolling. The table below shows the best order for skill upgrades:

Skill Type	Upgrade Priority
Special Attack	1
Chain Attack	2
Assist	3
Basic Attack	4
Dodge	5

Tip: Upgrading her Special Attack first gives your team a big boost in tough fights. Don’t waste resources on Dodge or Basic Attack early on.

Common Mistakes

You might run into a few problems when building Astra Yao. Here are some mistakes you should avoid:

• Ignoring her ATK stat. If you don’t reach 3430 ATK, her buffs won’t hit max power.
• Upgrading the wrong skills. Many players spend too much on Basic Attack or Dodge.
• Forgetting Energy Regen. Without enough, you can’t use her buffs often.
• Using the wrong discs. Some sets don’t match her support role.
• Not planning for material costs. Astra Yao needs a lot of Denny and special items for ascension and skill upgrades.

Note: Always check your materials before leveling up. You’ll need Support Certification Seals and Ether Chips at higher levels.
