Formule Phenomenale: Self-Evident Proposition
Lv. 10

Normal Attack
Generates threads that control her weapon using formulae, performing up to 3 consecutive strikes.

Charged Attack
Summons the Facilitatrice Automatisee Generaliste Interactive et Omnitache, or "Fagio," and switches it to Decoding mode: Unleashes a sweeping fire attack on enemies in front, as well as periodically fires condensed beams, dealing AoE Cryo DMG.
Radiance: Stellar Glimmer: The condensed beams will instead deal AoE Cryo DMG that is considered Stellar reaction DMG.
While in Decoding mode, Fagio's Decoding Power will continuously increase. Firing condensed beams will also further increase its Decoding Power.
When Fagio's Decoding Power reaches the maximum of 100 points, it switches to Power Overdrive mode, in which it fires at opponents with longer intervals, dealing Cryo DMG. It will be unable to switch to Decoding mode at this time.
When not in Decoding mode, Fagio's Decoding Power gradually decreases. When Sandrone is off-field, she will focus on maintaining Fagio, causing its Decoding Power to decrease at 300% the original rate.
Fagio exits Power Overdrive mode when its Decoding Power has decreased to under 50.

Plunging Attack
Plunges from midair to strike the ground below, dealing DMG to opponents along their path and causing AoE DMG on landing.

Formule Phenomenale: Differential Analysis
Lv. 10

With her impeccable, ladylike poise, Sandrone boards the Tea Party Tactical Assault Hovermech and hovers forward for 6s. During this time, Sandrone can control the travel direction of the craft. Pressing Sprint consumes 10 Stamina and launches her into an elegant high-speed hover mode, in which she will move even faster at the cost of 15 Stamina per second.

When Sandrone starts hovering, if there are opponents nearby, she will also summon a Prismatic Resonance Cannon and fire 2 Prism Shots at any opponents who have yet to cool down, dealing Cryo DMG.
Radiance: Stellar Glimmer: The second Prism Shot will instead deal Cryo DMG that is considered Stellar reaction DMG.

When on the Tea Party Tactical Assault Hovermech, Sandrone will also elegantly and quietly repair Fagio, causing Decoding Power to swiftly decrease.

In line with established ladylike behavior, Sandrone summons a large number of Prismatic Resonance Cannons for a frontal bombardment before firing on her foes with a Convective Inhibition Ray, dealing AoE Cryo DMG.

Eternal Speculation Engine

Radiance: Stellar Glimmer: When using the Elemental Skill Formule Phenomenale: Differential Analysis, if Fagio's Decoding Power is greater than 50, the second Prism Shot fired by Fagio at nearby opponents will deal 400% of its original DMG as Fagio's Decoding Power is decreased.
Additionally, for every 10 points of Decoding Power Fagio loses, it gains 1 stack of Refined Tactics for 60s (max 10 stacks). When Sandrone uses the Elemental Burst Formule Phenomenale: Q.E.D. while in the Radiance: Stellar Glimmer state, all stacks of Refined Tactics are cleared, causing the Convective Inhibition Ray to deal 100% + (number of stacks cleared) × 10% of its original DMG.

The maximum increase that can be gained this way is 14%.
Additionally, when Sandrone is within a Polestar Field, she will enter the Radiance: Stellar-Conduct state.
Sandrone will also enter the Radiance: Stellar Swirl state for 8s after triggering a Stellar Swirl reaction.

Hello

I hate self-introductions. If you're supposed to know me, you'll get to know me naturally, and if you're not... why waste the time and energy? But, very well — for the sake of etiquette, I'll humor you just this once... Behold, before you stands Marionette, Seventh of the Fatui Harbingers!

Chat: Tea Party

It's about time we threw another tea party, don't you think? I wonder who else is free...

Chat: Piano

I like music. In fact, I've taught myself to play many different instruments. You don't believe me? Hah, find me a piano, and I'll show you a thing or two.

Birthday Jan 13th Constellation Narcissorolegium Affiliation Fatui

Description

The Seventh of the Fatui Harbingers, "Marionette." Interprets all phenomena through the prism of mathematics, and is an elegant lady who is never absent from a tea party.

Character Details

Alain Guillotin would call her Marionette. Behind this name was the story of a loved one he could not forget and whose memories he had naively tried to revive by creating her. But the moment she opened her eyes and tentatively spoke his name, he resolved never to call her that again. It was wrong, he realized, to make this exquisite little creation bear the weight of his sister's life, and of his own mistake. This little creation deserved a life of her very own, just like anyone else born into this world.
But from time to time, he still addressed her by that name, if only in his thoughts. He did so because, just as the name "Marionette" suggested, she was pure of heart, kind, and always full of joy.
The people of Snezhnaya knew her as "the Lady" or "Lady Marionette." While most spoke of her with the fear that a Harbinger typically inspires, there was also often a distinct note of respect in their voices, a sentiment made clear by descriptions such as "the decisive Lady Marionette" and "the ever-reliable Lady Marionette."
But to her friends and colleagues, she was known as Sandrone. While it was originally just a code name, over time the name became a cheerful way for her closest and dearest to address her. They began to associate it with the scents of desserts and afternoon tea, with the elegant turning of book pages and the steady ticking of a mainspring.... And of course, at times, it also evoked the grumbles and even furious outbursts of a lady who had lost all patience, proper etiquette be damned.
Once, a friend put this question to her: "What do you want us to call you?"
"It doesn't matter, and I don't really care," she replied nonchalantly. "I've always thought names to be something that existed mainly for the convenience of others. What other people choose to call me is, to a very large extent, determined by which part of me they choose to accept."
The expression on her friend's face was one that clearly suggested that they were woefully unprepared for her answer.
"Anyhow, what I mean to say is: No matter what people choose to call me, I am still myself. I will not change because they have chosen to call me by a different name, and since I do not care for what people call me, why not just let them use the name they're most comfortable with? But as to whether I would respond to the name in question, that is another matter altogether, heh."

Sandrone's outfit. Having been reborn, she has decided to make herself a new outfit. A new person certainly merits a new dress. Naturally, such an undertaking cannot fail to incorporate a lady's refinement, elegance, and magnanimity... Ah, yes. And perhaps a prayer that it shall remain undamaged in battle, and unstained by coffee or tea, would not be remiss.
