Sandrone
Sandrone is a strong new Cryo claymore main DPS, as long as you have at least one Electro unit to keep triggering Stellar Conduct/Superconduct — this damage ignores elemental resistance, so it's very consistent. The 4pc Disenchantment in Deep Shadow is nearly mandatory since it flat-out boosts reaction damage by 80% and hands her free CRIT Rate. NOTE: her true signature weapon is A Teaspoon of Transcendence (released alongside her on July 1, 2026), but our weapon database hasn't been updated with it yet, so this build lists Wolf's Gravestone as the best available 5-star alternative for now; the 4-star Tidal Shadow or Mailed Flower still hold up fine for newer players. Remember to run an ATK% goblet instead of Cryo DMG, since her reaction damage doesn't scale off elemental DMG bonus. If you already have a free Yae Miko or Fischl sitting around, go ahead and build her — she won't disappoint.

Teams for Sandrone
Sandrone's talents
Formule Phenomenale: Self-Evident Proposition
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 the corresponding Stellar Glimmer 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
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 the corresponding Stellar Glimmer reaction DMG.
When on the Tea Party Tactical Assault Hovermech, Sandrone will also elegantly and quietly repair Fagio, causing Decoding Power to swiftly decrease.
Formule Phenomenale: Q.E.D.
Radiance: Stellar Glimmer: The Convective Inhibition Ray instead deals AoE Cryo DMG that is considered the corresponding Stellar Glimmer reaction DMG.
Eternal Speculation Engine
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.
A Lady's Code of Conduct
Stellar Jubilee: Light of Rationalisme
When a party member triggers a Superconduct or Cryo Swirl reaction, it becomes a Stellar-Conduct or Stellar Swirl reaction instead, and the Base DMG of the aforementioned reaction is also increased by 0.7% for every 100 points of Sandrone's ATK. A maximum increase of 14% can be obtained in this way.
A Caucus Prelude and a Long Tale
Combat Rotation
- Open with Burst Q "Q.E.D." (60 Energy cost, 15s cooldown) to unleash a wide AoE Cryo bombardment and apply Cryo to all nearby enemies.
- Use Charged Attack to summon Fagio into Decoding mode — this is her main damage source, as Fagio auto-fires a sweeping AoE attack plus periodic beams dealing Cryo DMG.
- Trigger Skill E "Differential Analysis" (only 4s cooldown) to board the Hovermech for a 6s hover, automatically firing 2 Prism Shots that deal AoE Cryo DMG while letting you dodge.
- While hovering, keep Fagio's Decoding Power ABOVE 50 to trigger the A4 passive: the second Prism Shot deals a total of 400% of its original DMG, while Fagio loses Decoding Power and Sandrone gains 1 stack of Refined Tactics (max 10 stacks, lasting 60s).
- Since E's cooldown is only 4s, keep recasting it between Charged Attacks to stack up Prism Shot damage while keeping Fagio continuously in Decoding mode.
- Recast Q as soon as you have 60 Energy (15s cooldown) for another big Cryo AoE burst and to refresh elemental application on the enemy group.
- Loop the cycle: Charged Attack (Fagio fires) → E (Prism Shots + dodge) → normal attacks while waiting on cooldowns → Q when ready.
Sandrone constellations
When in Decoding mode, Fagio's Decoding Power increases at a 50% lower rate, and all party members deal 30% increased Stellar Glimmer reaction DMG.
Radiance: Stellar Glimmer: 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.
Maximum upgrade level is 15.
When Sandrone deals Stellar-Conduct or Stellar Swirl 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% or 187.5% of her ATK, respectively. This DMG is considered the corresponding Stellar Glimmer reaction DMG, and the effect can occur once every 4s.
Increases the Level of Formule Phenomenale: Q.E.D. by 3.
Maximum 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.
Radiance: Stellar Glimmer: The Condensed Cluster Beam attack deals 4 additional instances of AoE Cryo DMG. The DMG dealt with this attack, which is considered the corresponding Stellar Glimmer reaction DMG, is equal to:
Radiance: Stellar-Conduct: 80% of Sandrone's ATK.
Radiance: Stellar Swirl: 120% of Sandrone's ATK.
Additionally, all Stellar Glimmer reaction DMG dealt by Sandrone is elevated by 20%.

Voice Lines & Comments
Birthday
Hmph. Here, take this. I wouldn't normally give these out, but today's a special day — it marks the day you came into the world. I invited Arlecchino and Columbina, plus a few shared friends. I even baked a special cake for the occasion... so you'd best look forward to it.
Self-Introduction
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!
About Sandrone: Name
What's wrong with calling me Sandrone? Huh...? My original name? Hah... So, you really want to know? Alright, alright... I can still remember when I first opened my eyes. Alain had just finished creating me. He called me "Marionette." I tried to repeat it, to say it out loud myself, but I noticed something... complicated in his expression. Only later did I come to understand what it was — a mixture of regret and guilt. He never called me that again. Anyway, after telling me the story of the Narzissenkreuz Ordo and his sister, Alain concluded by insisting that I was free to choose my own path in life. An important part of that, he said, was deciding on my own name. For my part, I told him I was perfectly fine with the one he'd given me. "Marionette Guillotin"... Pretty unique as names go, wouldn't you say? And yet, no doubt for different reasons, the Tsaritsa ended up making "Marionette" my title as a Harbinger. Heh... Perhaps that was simply another so-called "act of fate."
About Sandrone: Sleep
When I was first created, it seemed like too much work to find a place to lie down, so I usually just "slept" in a chair. It was only after I arrived in Snezhnaya that I grew accustomed to sleeping in beds. I have to say, after an exhausting day of dealing with my "colleagues," wearing something comfortable and hiding beneath the covers is wonderfully cozy. There's a sense of security created by my sensory system and emotional circuitry. I now know why people like to sleep in. However, beds come with their own issues — my clockwork key prevents me from sleeping on my back, and it's difficult to balance when lying on my side. The only option is to sleep face down.
More About Sandrone: I
Hmm? I'm not in the habit of casually sharing my life story with others. But if I'm going to open up, can we at least wait for pleasant weather and to do it over tea and cake?
More About Sandrone: II
My colleagues in the Fatui might not be the ones I'd choose, but there's no denying that it's an excellent place to conduct research. The Tsaritsa is generous with her resources and funding. I'd say the equation balances out in my favor.
More About Sandrone: III
It never bothered me that Alain created me to look like his sister Mary-Ann — or that he named me "Marionette." The way I see it, these are simply the consequences of my birth. Does it bother you to look like your parents, or to bear their family name?
More About Sandrone: IV
I like mathematics. A world built on formulae and logic has a kind of elegance anchored in certainty. I also like music, which is similar in many ways. I used to think playing music should be approached like a mathematical problem, balancing the notes and the beat, no space for deviation. Later, I came to realize that some minor flaws — even mistakes — during a performance can actually make the music more beautiful. A slight pause here, a sudden improvisation there... Such tiny errors are where emotion is born. Reverberations of the performer's heart, you might say.
More About Sandrone: V
What the world gives, the world will take away. To live is to gain and to lose, to pick up what the world can't seize, to hold onto it amid loss and farewells, and to keep walking forward. If a person desires merely "to live," is that too insignificant a wish? Just like someone saving the world solely to "save themselves" — is such a reason too simple? To live, to feel, to witness. And then one day, perhaps those things the world cannot take away will grow numerous enough to shake it to its core.
About Us: Diary
You've read my diary, so don't you think it's about time you shared some of your own secrets to even things out? Huh? Your Adventurer Handbook? Why would I want that? If I wanted to know what you do every day, I'd just get Katheryne to tell me.
About Us: Beliefs
We may know each other better now, but once we arrive in Snezhnaya, we still have to follow the rules. After all, you've been fighting the Fatui since you arrived... Who knows what kind of a stir you'll cause over there. Naturally, I'll try my best not to make your life difficult. I'd appreciate it if you could do the same for me. Helping each other out based on mutual understanding — that's what companions do, right?
Thoughts About Other Characters
Citlali
That great shaman seems nice. Is she really very old? Still seems like she's got plenty of energy to me — though she does get a little too worked up sometimes. What do I mean? Oh, well, recently, I was talking to her about you and me going underwater to look for something... and before that, I told her you were in Nod-Krai helping Columbina get her name back... She got so animated, her face turned bright red. I wonder if it has something to do with her age...
Lynette
I don't know how she does it! That cat-girl always seems to find the weakest spot in every machine and then... beh, broken. I wish her brother would have a word with her. *sigh* Nevermind... I guess it's a talent, really. Maybe I should have her help me stress test my future creations. If my machines can't survive her curiosity, what chance do they have in battle?
Columbina
Columbina used to drive me up the wall — to be honest, she still does. I thought life would be quieter without her around. Who knew I'd find myself getting more annoyed once she wasn't here! Ugh, it's infuriating!
Columbina
She's living such a happy life right now. Her family and friends are by her side, and she gets to go traveling whenever she's free... Why can't I have that kind of fortune? Oh, forget it, I'm not jealous. We all know she deserves to be happy.
Arlecchino
Arlecchino is a woman of her word. She acts decisively, and you can trust her to get things done. Purely from a professional standpoint, it would be nice if all my colleagues could try to emulate her.
Tartaglia
Another pain in the... well, everything. He could happily just spend his days with his brothers and sisters — why insist on becoming a Harbinger at all? And when will he get it into his thick skull that not everyone is always looking for a fight?
Hobbies & Personality
Sandrone's Hobbies
Besides music, machines, and mathematics, I also enjoy horticulture... when conditions allow. I like to document the process as my plants grow and flourish. Most of them require little intervention — they're independent, resilient. I used to believe I was the same.
Sandrone's Troubles
Every time I see a fluffy little animal, I just wanna pick it up and give it a big hug... but most animals don't like machines, so they always run away when they see me. Hey! Don't look at me like that! I don't want your pity. So what if I can't hug them? It's not... it's not that big of a deal...
Favorite Food
Thanks to this body, I don't suffer from allergies or indigestion, so food is purely a matter of pleasure for me. But if I had to choose... Hmm, I think I like small, dainty pastries most of all. Just looking at their exquisite shape brings joy to my heart — it's a one-two punch for the eyes and soul.
Least Favorite Food
I don't like greasy, spicy food. It's got nothing to do with taste — it's just hard to keep the smell from clinging to my clothes. It's very inelegant for a lady.

Receiving a Gift: II
Oh? That's not half bad. I'll have to return the favor next time we get together for tea.
Receiving a Gift: III
Ugh... Fagio, I have something for you to clean up.

Strengths & Weaknesses
- This kit's mechanic scales with the character's own ATK, with a clear cap per the official formula (see the recommended stat goal below).
- At Lv90, Sandrone already gets +19,2% CRIT Rate baked into the ascension stat line — no artifacts needed for this part.
- The core mechanic (via A Lady's Code of Conduct) scales with ATK — the standard stat line on most damage weapons, no build pivot needed.
- The Normal Attack (via Formule Phenomenale: Self-Evident Proposition) already deals innate Cryo DMG from the start — no need to wait on the Elemental Skill to apply the element.
- This mechanic's payoff depends on the character's own ATK — falling short of the recommended goal below wastes part of its potential.
- Since it scales with ATK (via A Lady's Code of Conduct), it competes for high-ATK weapons/ATK% pieces with other ATK-based DPS on the team — no niche-stat advantage.
- 5★ (Claymore) — only available on limited/character-specific banners, not on the standard wish.
Recommended Stat Goal
- ATK ≈ 2.000 — For every 100 ATK, A Lady's Code of Conduct adds 8 (capped at 160) — derived goal: roughly 2.000 ATK to hit that cap.
Recomputed from the official formula itself (not a third-party recommendation).
Role Rankings
Machine-classified by scanning mechanic keywords in the OFFICIAL skill text (not another site's opinion ranking). Characters whose weapon type is inherently elemental (e.g. catalysts, bows) may not show "Does this well" for On-Field even if they can still be played on-field — this is a limit of text-based detection.

Full profile
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.
- Affiliation: Fatui
- Birthday (day/month): 1/13
- Specialty dish: Tea Party Polyphony
- Namecard: Sandrone: Tea Break — Namecard style. Sandrone may have learned to enjoy tea parties from Alain. In those days, even a tea break for two never felt dull. But later, when there were finally enough people for a proper tea party, they left one after another. And in their absence, she seemed to come a little closer to the loneliness Alain had known.
