12-Tone Equal Temperament

"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.

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.

02

Art of Greed

"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.

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.

03

Interwoven Staff Notation

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...

Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2

"Hair Upon Your Nape"

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

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.

05

Proxy and Silk String

"Eve! I've just realized something huge — both you and (‍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.

Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2

06

We Are the World

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!"

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.
