Normal Attack\nGenerates threads that control her weapon using formulae, performing up to 3 consecutive strikes.\n\nCharged Attack\nSummons 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.\nRadiance: Stellar-Conduct: The condensed beams will instead deal AoE Cryo DMG that is considered Stellar-Conduct DMG.\nWhile in Decoding mode, Fagio's Decoding Power will continuously increase. Firing condensed beams will also further increase its Decoding Power.\nWhen 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.\nWhen 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.\nFagio exits Power Overdrive mode when its Decoding Power has decreased to under 50.\n\nPlunging Attack\nPlunges from midair to strike the ground below, dealing DMG to opponents along their path and causing AoE DMG on landing.

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.\nRadiance: Stellar-Conduct: The Convective Inhibition Ray instead deals AoE Cryo DMG that is considered Stellar-Conduct DMG. \n\n"I can believe in something so long as solid evidence can be produced for it. If not, then I will have to first prove it."\n"This is how a proper lady carries herself. She who submits to the unknown out of weakness of will cannot be called such."

Radiance: Stellar-Conduct: 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.\nAdditionally, 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-Conduct 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.

Increases Sandrone's Elemental Mastery based on her ATK. Every 100 ATK will increase her Elemental Mastery by 8. The maximum increase she can gain this way is 160.

When party members trigger Superconduct, it will be changed to Stellar-Conduct, and party members' Base Stellar-Conduct DMG will be increased based on Sandrone's ATK: Every 100 ATK she has increases the Base Stellar-Conduct DMG by 0.7%. The maximum increase that can be gained this way is 14%.\nAdditionally, when Sandrone is within a Polestar Field, she will enter the Radiance: Stellar-Conduct state.

When Sandrone is in the party, you will gain additional snack rewards after turning in your Daily Commissions with Katheryne.

When in Decoding mode, Fagio's Decoding Power increases at a 50% lower rate, and all party members deal 30% increased Stellar-Conduct DMG.

Radiance: Stellar-Conduct: Increases CRIT DMG from Charged Attack condensed beams by 40%. Also, each time a beam is fired, CRIT DMG dealt by all condensed beams fired during this Decoding mode period will be further increased by 20%. Max 3 stacks.

Increases the Level of Formule Phenomenale: Self-Evident Proposition by 3.\nMaximum upgrade level is 15.

When Sandrone deals Stellar-Conduct DMG to an opponent, she will also summon an extra Prismatic Resonance Cannon to fire off a coordinated attack which deals Cryo DMG at 125% of her ATK. This DMG is considered Stellar-Conduct DMG, and the effect can occur once every 4s.

Increases the Level of Formule Phenomenale: Q.E.D. by 3.\nMaximum upgrade level is 15.

When Fagio fires a condensed beam for the third time while in Decoding mode, the beam becomes a more powerful Condensed Cluster Beam that fires continuously. This beam will deal up to 4 additional instances of AoE Cryo DMG at 100% of Sandrone's ATK on top of any subsequent original beam fired.\nRadiance: Stellar-Conduct: The Condensed Cluster Beam will instead deal 4 additional instances of AoE Cryo DMG at 80% of Sandrone's ATK. This DMG is considered Stellar-Conduct DMG.\nAdditionally, all Stellar-Conduct DMG dealt by Sandrone is elevated by 20%.
