When any squad member enters the field through a Quick Assist, Chain Attack, Defensive Assist, or Evasive Assist, the equipper gains 5 Energy. This effect can trigger once every 5s. When the equipper consumes 25 or more Energy, the DMG dealt by all squad members increases by 10%, stacking up to 2 times, and lasting 20s. Repeated triggers reset the duration. Only one instance of this effect can exist in the same squad.
This is the agent's engine by design - not necessarily the one people actually run. For what is actually equipped, see below.

"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.
M2

"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.
M3
Interwoven 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...
M4
"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.

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
M5
Proxy and Silk String
Basic Attack, Dodge, Assist, Special Attack, and Chain Attack Lv. +2
"Eve! I've just realized something huge — both you and {M#Wise}{F#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.
M6
We Are 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.
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!"
