Sandrone Gameplay
Sandrone's gameplay revolves around dealing powerful Stellar-Conduct DMG through her Charged Attack beams. While carefully managing Fagio's Decoding Power and Refined Tactics stacks to maximize her burst windows. Her kit focuses on cycling between her Charged Attack and Elemental Skill, making her highly effective as a dedicated on-field DPS in Cryo and Electro teams.
Her Charged Attack deploys Fagio in Decoding Mode, where it fires condensed beams that deal AoE Cryo DMG. While Sandrone is in the Radiance: Stellar-Conduct state, these condensed beams instead deal Cryo DMG considered as Stellar-Conduct DMG. These beams continuously build Decoding Power up to 100. Once Decoding Power reaches its maximum, Fagio enters Power Overdrive Mode, where beam damage drops significantly and Decoding Mode can no longer be activated. The primary way to reset this is through her Elemental Skill: Formule Phenomenale: Differential Analysis, which boards a hovermech and fires 2 Prism Shots. While in Radiance: Stellar-Conduct, the second Prism Shot deals Cryo DMG considered as Stellar-Conduct DMG, while also rapidly depleting Decoding Power to reset her rotation. With only a 4-second cooldown, this creates a fluid core loop of alternating Charged Attack beams and Elemental Skill casts.
Sandrone enters the Radiance: Stellar-Conduct state when standing within a Polestar Field, which is generated when party members trigger the Stellar-Conduct reaction. When Sandrone uses her Elemental Burst: Formule Phenomenale: Q.E.D. while in this state, it launches a frontal bombardment dealing AoE Cryo DMG, followed by a Convective Inhibition Ray that deals Cryo DMG considered as Stellar-Conduct DMG. Casting the Burst while Radiance: Stellar-Conduct is active also clears all accumulated Refined Tactics stacks, which are built through her Elemental Skill reducing Decoding Power while in the Radiance: Stellar-Conduct state, causing the Convective Inhibition Ray to deal up to 200% of its original DMG at maximum stacks. Her passive talent A Lady's Code of Conduct further converts every 100 ATK into 8 Elemental Mastery (up to 160), naturally strengthening her Stellar-Conduct reaction damage as she scales ATK. Sandrone performs best when built around frequent Cryo and Electro application from teammates, precise Elemental Skill timing to fully stack Refined Tactics before her Burst, and sustained on-field rotations that keep her Charged Attack uptime as high as possible.

Sandrone Talent Priority
Sandrone's talent priority focuses primarily on her Normal Attack, as her Charged Attack beams are the core of her kit and the main source of her damage throughout her rotation. Her Elemental Burst comes next, as Formule Phenomenale: Q.E.D. delivers one of her strongest single damage instances when Refined Tactics stacks are fully built up. Her Elemental Skill is the lowest priority, as it primarily serves as a rotation tool to reset Decoding Power rather than a direct damage source.
| Talent | Recomended Level | ||
| Normal Attack (Formule Phenomenale: Self-Evident Proposition) | 9-10 | ||
| Elemental Burst (Formule Phenomenale: Q.E.D.) | 9-10 | ||
| Elemental Skill (Formule Phenomenale: Differential Analysis) | 1-6 | ||
Normal Attack - Formule Phenomenale: Self-Evident Proposition
Sandrone's Normal Attack is her highest priority. Her Charged Attack condensed beams fired by Fagio in Decoding Mode are the attacks she uses most frequently on-field, and leveling this talent directly increases their damage output. Since the majority of her total DPS comes from these Stellar-Conduct beam hits, this talent delivers the highest return on investment and should always be maxed first.
Elemental Burst - Formule Phenomenale: Q.E.D.
Sandrone's Elemental Burst is her second priority. It deals a powerful frontal bombardment followed by a Convective Inhibition Ray that is significantly amplified when all Refined Tactics stacks are cleared on cast. Building enough Energy Recharge to use it every rotation is strongly recommended, as it consistently contributes a large portion of her total damage output.
Elemental Skill - Formule Phenomenale: Differential Analysis
Sandrone's Elemental Skill is her lowest priority. Its primary role is to reset Fagio's Decoding Power and build Refined Tactics stacks rather than deal significant damage. While the second Prism Shot does deal Stellar-Conduct DMG, the damage scaling on this talent is noticeably lower than her Charged Attack and Burst, making it safe to leave at a low level without meaningfully impacting her overall damage output.
Sandrone Best Weapons
To maximize Sandrone's DPS, prioritize CRIT Rate, CRIT DMG, ATK%, and Energy Recharge. Her overall damage heavily depends on keeping her Charged Attack uptime high and ensuring her Elemental Burst is cast with fully stacked Refined Tactics every rotation. Weapons that directly boost Charged Attack DMG, provide strong ATK scaling, or help meet her Energy Recharge needs will always outperform pure utility options on her.

Sandrone Best Artifacts & Stats
To maximize Sandrone's performance as a dedicated on-field DPS, artifact choices should prioritize CRIT Rate, CRIT DMG, ATK%, and enough Energy Recharge to cast her Elemental Burst every rotation. Since her main role is to deal massive Stellar-Conduct DMG through her Charged Attack beams and Formule Phenomenale: Q.E.D., the best sets are those that enhance her personal damage output, improve her burst consistency, and strengthen her overall offensive pressure rather than providing pure team utility.

Sandrone Best Team Compositions
Sandrone performs best in teams that help her maintain consistent Cryo and Electro application to keep the Stellar-Conduct reaction active, maximize Refined Tactics stacks before her Burst, and support her sustained on-field Charged Attack uptime. She is mainly played as a dedicated on-field Cryo DPS, relying on teammates to frequently trigger Stellar-Conduct while also providing ATK buffs, RES Shred, and off-field damage to complement her rotation. Since much of her damage scales around staying within the Polestar Field and maintaining Radiance: Stellar-Conduct, Sandrone becomes especially strong in teams built around reliable Electro off-field applicators, Cryo buffers and healers, and supports that provide ATK amplification or RES Shred for both Cryo and Electro.
Note: Several existing characters received kit buffs in Version 6.7 to better support Stellar-Conduct teams. Beidou, Cyno, Diona, Qiqi, and Wriothesley all received new passives or constellation additions that interact directly with the Radiance: Stellar-Conduct state, making them more viable options for Sandrone's team compositions.

Sandrone Constellations
Sandrone is already fully functional at C0 as a dedicated on-field Cryo DPS, with access to her full Charged Attack rotation, consistent Stellar-Conduct DMG, and powerful burst windows through Formule Phenomenale: Q.E.D.. Her constellations mainly improve her personal damage output by extending Decoding Mode uptime, increasing Crit DMG scaling, and adding stronger follow-up damage rather than changing her core playstyle. Among them, C2 stands out as her best early premium investment due to its powerful Crit DMG stacking on condensed beams, while C4 adds a reliable coordinated attack that fires every rotation. C6 serves as her strongest late-game investment with massive damage amplification and a major upgrade to her Charged Attack beam pattern.
Constellation Performance
| Constellation | Rating | Reason | ||
| C1 | ★★★★ | Slows Decoding Power buildup by 50%, giving Sandrone more time in Decoding Mode before hitting Power Overdrive. Also grants the whole team +30% Stellar-Conduct DMG, making it a decent team-wide upgrade but not a massive personal DPS spike. | ||
| C2 | ★★★★★ | A major offensive upgrade that stacks +40% Crit DMG on condensed beams and further increases Crit DMG by up to +60% as additional beams are fired during Decoding Mode. This is the best premium stopping point for most players and delivers the highest DPS return per constellation invested. | ||
| C4 | ★★★★ | Adds a coordinated Stellar-Conduct follow-up attack dealing 125% ATK every 4s whenever Sandrone deals Stellar-Conduct DMG. Provides consistent additional damage throughout her entire rotation with no extra effort required. | ||
| C6 | ★★★★★ | Sandrone's strongest constellation. Every third condensed beam in Decoding Mode becomes a Condensed Cluster Beam that fires 4 additional Stellar-Conduct DMG hits, and all Stellar-Conduct DMG she deals is elevated by +20%. Provides her largest overall DPS increase and makes her the ultimate late-game investment. | ||
Constellation Effect
| Constellation | Effect | ||
| C1 | "Morrow After the Golden Dusk" When in Decoding Mode, Fagio's Decoding Power increases at a 50% lower rate, and all party members deal 30% increased Stellar-Conduct DMG. | ||
| C2 | "An Heiress Gazed Into the Looking-Glass" While in Radiance: Stellar-Conduct, increases Crit DMG from Charged Attack condensed beams by 40%. Each time a beam is fired, Crit DMG dealt by all condensed beams during this Decoding Mode period is further increased by 20%, up to 3 stacks. | ||
| C3 | "Refuse the Wake of Dusk, the Moonlit Yoke" Increases the level of Formule Phenomenale: Self-Evident Proposition by 3. Maximum upgrade level is 15. | ||
| C4 | "In Knowledge Lies the World's True Ground" When Sandrone deals Stellar-Conduct DMG, she summons an extra Prismatic Resonance Cannon to fire a coordinated attack dealing Cryo DMG considered as Stellar-Conduct DMG at 125% of her ATK. This effect can occur once every 4s. | ||
| C5 | "Of All Beside, She Takes No Part" Increases the level of Formule Phenomenale: Q.E.D. by 3. Maximum upgrade level is 15. | ||
| C6 | "Narcissus Wakes, Her Eyes Upon the Dawn" When Fagio fires a condensed beam for the third time while in Decoding Mode, the beam becomes a Condensed Cluster Beam that fires continuously, dealing up to 4 additional instances of AoE Cryo DMG considered as Stellar-Conduct DMG at 80% of Sandrone's ATK. Additionally, all Stellar-Conduct DMG dealt by Sandrone is elevated by 20%. | ||
