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.
What it costs to finish this character
Ascension alone: 760 resin (boss drops only) · talents alone: 590 resin.
Talent books: Vagrancy. To show the days this domain opens, add its row to the rotation table — the six regions already in it are there, and this one is not, so no day is claimed for it.
A Crown of Insight is needed for the tenth level of each talent, and crowns are not farmable at any resin price — they come from events.
Materials and mora above are exact, straight from the game’s own tables. The resin figure and the day count divide by an average drop per run, which the game does not publish — they are a community-measured mean, not a promise.

Talents
Formule Phenomenale: Self-Evident Proposition
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 {LINK#N11330001}Decoding{/LINK} mode: Unleashes a sweeping fire attack on enemies in front, as well as periodically fires condensed beams, dealing AoE Cryo DMG.
{LINK#N11500004}Radiance: Stellar Glimmer{/LINK}: The condensed beams will instead deal AoE Cryo DMG that is considered the corresponding Stellar Glimmer reaction DMG.
While in Decoding mode, Fagio's {LINK#N11330002}Decoding Power{/LINK} 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
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.
{LINK#N11500004}Radiance: Stellar Glimmer{/LINK}: The second Prism Shot will instead deal Cryo DMG that is considered the corresponding Stellar Glimmer reaction DMG.
When on the Tea Party Tactical Assault Hovermech, Sandrone will also elegantly and quietly repair Fagio, causing {LINK#N11330002}Decoding Power{/LINK} to swiftly decrease.

To turn this into a real recommendation section, add a build dataset — per character, the weapons and sets a community source actually recommends, with the rotation each assumes. Nothing in the game’s published data contains that judgement, and a ranking invented here would be indistinguishable from a researched one, which is why there is not one.

To build a team section, add team data. Which characters go together is judgement about rotations, energy and shielding that this product does not receive and will not guess at.
