SBest Astra Yao Build Guide
Written by Phạm Ngọc Bảo Châu ·
Playstyle Overview
Astra Yao is an Ether Support who fits almost any team. Her Special Attack puts her into Idyllic Cadenza, raising the whole team's DMG and CRIT DMG. When you swap out, Astra stays on the field, and while she has Chords, the active character's hits trigger Quick Assists. Each time a teammate enters through a Quick Assist, Chain Attack or Assist, her Core Passive Graceful Andante boosts both Astra's and the incoming Agent's ATK.
Her Ultimate heals the team and turns the next 2 Quick Assists into Chain Attacks. Prioritize ATK, then Energy Regen. The only real drawback is that your team ends up with just two Agents rotating on the field.

- Anomaly Proficiency
- Any amount (Anomaly route, instead of CRIT)
Your top priority is reaching about 3,430 ATK so her Core Passive buff is maxed. Use her set, main stats, substats and W-Engine together to get there. After that, grab as much Energy Regen as you can, since more Energy means more Quick Assists. Once those are covered, pick one direction: CRIT, or Anomaly Proficiency for Anomaly teams (replacing CRIT in the substat list). Never mix both.

Basic Attack
Core Skill and Special Attack matter equally. The Core Skill raises her ATK buff, while Special Attack raises the DMG buffs during Idyllic Cadenza. Chain Attack comes next for more Ultimate healing and damage. Assist, Dodge and Basic Attack contribute little, so leave them for last.

Mindscape Cinema
Which Mindscapes Are Worth It?
If you want to invest further, M2 is the best stopping point. Her Core Passive ATK buff gets stronger and has a higher cap. M1 is great thanks to its All-Attribute RES reduction, and M6 turns Astra into a genuine Sub-DPS. M3 and M5 only add skill levels and are not counted.
- M1Astra's hits reduce enemy All-Attribute RES by up to 18%. She enters combat with 1,000 Decibels, and her Ultimate gives the whole team a one-time brief invulnerability when attacked.
- M2Her Core Passive ATK buff rises by another 19% with a cap 400 higher. Whenever a teammate enters during Idyllic Cadenza, Astra adds an extra Tremolo and follow-up hits, which means stronger buffs and more damage.
- M4After a Chain Attack or Ultimate, Astra can trigger Quick Assists for 15s even without Chords. Agents entering via Quick Assist get a role-based bonus (extra DMG for Attack, Anomaly Buildup for Anomaly, Daze for Stun).
- M6During Idyllic Cadenza, Tremolo and her follow-up hits get double multipliers plus +80% CRIT Rate. This turns Astra into a real Sub-DPS on top of her buffing role.
M112-Tone Equal TemperamentRecommended
When Astra Yao's attack hits an enemy, the target's All-Attribute RES is reduced by 6%, stacking up to 3 times and lasting 30s. Repeated triggers refresh the duration.
Upon entering the battlefield, Astra Yao immediately gains 1,000 Decibels.
When activating her Ultimate, all squad members gain 1 stack of Song of Protection for 60s. When attacked by an enemy, consume Song of Protection, granting Invulnerability for 1s.
"What is the 12-tone equal temperament?"
"12-tone equal temperament is a musical tuning system, just like how children have to line up, sounds need to be in order too."
"But sounds probably don't like lining up, just like children!"
—Astra Yao's music teacher, recalling when she was six.
M2Art of GreedRecommended
The ATK buff from Core Passive: "Graceful Andante" is further increased by 19%, with an increased maximum of 400. While in the Idyllic Cadenza state, when other squad members switch in through a Quick Assist, Chain Attack, Defensive Assist, or Evasive Assist, Astra Yao will additionally follow up with 1 Tremolo and 3 Tone Clusters to attack. This effect can trigger once every 3s.
"The shiniest thing in the world is, of course, love!"
Just like a bird gathering shiny things for its nest, an artist's inner greed is probably to gather all the love in the world. By gathering all the love, one can create the most beautiful melody.
M3Interwoven Staff Notation
Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2.
A blank musical staff is a set of parallel lines that never intersect, like souls that have never met, quietly waiting for their melodies to intertwine into a song.
"Let's fill it with notes! And lots and lots of tied notes. It'll make a fantastic song!"
And that's how a new song was created, stretching across 136 bars, all connected with ties...
M4Hair Upon Your NapeRecommended
After activating a Chain Attack or Ultimate, within 15s, Astra Yao can trigger a Quick Assist even if she does not have Chords. When the attack hits an enemy, the interval for triggering a Quick Assist is reduced to 1s.
While in the Idyllic Cadenza state, when other squad members enter the field via a Quick Assist, they will receive different buffs based on their specialty, and this effect can be triggered once every 3s for the entire squad:
Attack: The next Quick Assist heavy attack on an enemy will deal extra DMG equal to 300% of Astra Yao's ATK;
Anomaly: The next Quick Assist will have 50% increased Anomaly Buildup;
Stun: The next Quick Assist will inflict 50% increased Daze.
One hand hovers over the piano
Not sure which note will bring me peace
A sad minor key
Or gentle melody of longing?
I seek your shadow through the score I close my eyes, and see you more
Such as the hair upon your nape
M5Proxy and Silk String
Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2.
"Eve! I've just realized something huge — both you and Proxy(Wise/Belle) are tall and slim!"
"...And your point being...?"
"You're both my favorite people!"
Astra beamed with joy, as if she had uncovered an earth-shattering secret.
M6We Are the WorldRecommended
While in the Idyllic Cadenza state, the DMG multiplier for Tremolo and Tone Clusters released or followed up with will increase to 200% of the original, and CRIT Rate is increased by 80%.
When triggering a Precise Assist, Astra Yao will automatically follow up with the charged 3rd-hit of Basic Attack: "Capriccio", with a 80% increased CRIT Rate. This effect can trigger once every 10s.
The turmoil in the world originates from the solitude of the human heart. If everyone's heart was reciprocated, perhaps all the suffering, sadness, and silence in the world would vanish?
If we could weave this connection with song, would all the cracks heal, and all the pain turn into a beautiful melody, filling the silence? At that point, the world would no longer be a lonely island.
"This song is dedicated to the world!"

Story
Agent Profile: Astra Yao
Astra Yao is widely regarded as Ridu's most iconic singer. With her extraordinary voice, stage presence, and songwriting talent, she has led the musical trends of an entire era. "If music is the resonance of the soul, then Astra Yao is the spark that ignites it all," said one famous music critic.
As brilliant as she is, Astra remains remarkably sincere and pure. On stage, her voice resonates deeply with the audience, which has allowed her to amass a large and loyal fanbase known as her "Astranauts." Of course, Astra's brilliance wouldn't be possible without the careful protection of her manager, Evelyn. Offstage, she appears to be just a cute, hapless girl who depends on Evelyn in her daily life, and on Wise and Belle in the Hollows.
"If I tickled Eous, would it make you laugh?" Astra asked curiously while lifting the Proxy, who was linked via the HDD system.
She seems to have a particular fondness for Eous. Contemplation: Human emotions are indeed an interesting subject. It's still hard to determine whether Astra likes Eous because of the owner, or whether she likes the owner because of Eous.

Astra is particularly fond of Random Play. However, her whereabouts are closely monitored. For now, it seems she can still use an excuse like, "The store offers rare versions of old movies, and I've got such good taste in movies, so of course I'd love it!" But being the biggest celebrity in Ridu, such frequent visits to a video rental store are not exactly conducive to keeping our identity under wraps. But, who cares about that! If our identity gets exposed, so be it — Astra can't not come. Contemplation: Creating various situations to bring Astra and Master together is a great way to win the Master's favor.
Hồ Sơ Người Đại Diện: Astra Yao (Phần 1)
Astra đặc biệt yêu thích "Random Play". Nhưng hành tung của cô luôn bị nhiều phía để ý, hiện tại dường như vẫn có thể mượn lý do "Đây là một cửa tiệm có thể cung cấp nhiều bộ phim cũ quý hiếm, Astra rất có gu trong việc chọn phim, dĩ nhiên là phải thích rồi!" để lấp liếm cho qua. Nhưng dù sao cũng là đại minh tinh của Ridu, xuất hiện trong tiệm băng hình thường xuyên như vậy rất bất lợi cho việc che giấu thân phận. Nhưng, ai thèm quan tâm chứ? Thân phận bại lộ thì cứ bại lộ đi, Astra không thể không đến. Suy nghĩ: Tạo ra các tình huống kết nối Astra và chủ nhân, là một cách hay để lấy lòng chủ nhân.
Hồ Sơ Người Đại Diện: Astra Yao (Phần 2)
Astra Yao là một "diva hàng đầu của Ridu" được mọi người công nhận, nhờ vào chất giọng siêu phàm, khả năng lan tỏa trên sân khấu và tài sáng tác tuyệt vời mà cô đã dẫn đầu trào lưu âm nhạc của cả một thời đại. "Nếu âm nhạc là sự cộng hưởng của tâm hồn, vậy thì Astra Yao chính là pháo hóa thắp sáng tất cả mọi thứ." Một nhà phê bình nổi tiếng đã từng bình luận về cô như vậy. Dù rực rỡ như thế, nhưng Astra Yao vẫn luôn giữ trọn sự chân thành và thuần khiết đáng quý. Trên sân khấu, tiếng hát của cô trực tiếp đi thẳng vào trái tim mỗi người, chính đặc trưng này đã khiến cô sở hữu một cộng đồng fan hâm mộ trung thành hùng hậu mang tên "Astranaut". Tất nhiên, hào quang của Astra Yao cũng không thể thiếu đi sự bảo vệ tận tình của người quản lý Evelyn. Còn bên dưới sân khấu, cô dường như chỉ là một cô gái đáng yêu thích dựa dẫm vào Evelyn trong cuộc sống, và dựa dẫm vào Wise và Belle khi ở trong Lỗ Hổng. "Bây giờ nếu tôi thọc lét Eous thì cô/cậu sẽ bật cười chứ?" - ôm lấy Người Kết Nối liên kết thông qua hệ thống H.D.D, Astra tò mò hỏi. Dường như cực kỳ yêu mến Eous. Suy nghĩ: Cảm xúc của con người đúng là một chủ đề thú vị. Rốt cuộc Astra Yao là vì Eous nên mến luôn chủ nhân, hay vì chủ nhân nên yêu mến Eous, điều này không thể phán đoán được.
