Massive Genshin Impact 6.7 Leak Reveals Sandrone’s Full Kit, Stella Superconduct Reactions and Fageo Combat System

A massive new Genshin Impact 6.7 leak has allegedly revealed the complete gameplay kit for Sandrone, giving players their clearest look yet at how the long awaited Fatui Harbinger may function in combat. The leaked information showcases an extremely unique Cryo focused playstyle centered around a new reaction mechanic called Stella Superconduct, alongside advanced automaton systems, hover based mobility and sustained battlefield pressure.

According to the leaked beta data, Sandrone’s gameplay revolves around an autonomous machine called Fageo, a fully functional universal automaton capable of entering multiple combat states through something known as Calculation Mode.

• Her Normal Attack:
  Phenomenon Formula: Self-Evident Deduction, allows Sandrone to manipulate bladed weapons using mathematical threads, performing up to three consecutive slashes. However, the core of her gameplay appears tied to her Charged Attack mechanics.
  When using a Charged Attack, Sandrone summons Fageo into Calculation Mode. During this state, the automaton suppresses enemies ahead while periodically firing Condensation Rays that deal AoE Cryo damage. Under the enhanced Radiance: Stella Superconduct state, these attacks instead count as Stella Superconduct reaction damage.
  One of the most interesting mechanics in the leak is Calculation Power, a resource that constantly increases while Fageo remains active in Calculation Mode. Once the gauge reaches 100, Fageo enters Overclock Mode, becoming more destructive but temporarily unable to re-enter Calculation Mode.

This creates what many theorycrafters describe as a resource management playstyle where players must carefully balance offense, reaction damage and cooldown timing.

• Sandrone’s leaked Elemental Skill:
  Phenomenon Formula: Extended Analysis, appears to be equally impressive. The skill allows her to ride a tactical hover-device for six seconds while continuously gliding forward. During this movement state, players can freely control direction and activate a faster hover sprint by consuming stamina.
  Many players are already comparing the mechanic to a fusion between Neuvillette’s movement fluidity and Yelan’s open world traversal, supporting earlier leaks claiming Sandrone would possess exceptional exploration capabilities.
  The Elemental Skill also summons a Prismatic Resonance Cannon, firing Prism Shells that deal Cryo damage. Under the Stella Superconduct state, the second projectile converts into enhanced reaction based damage.

Interestingly, the hover-device also serves another purpose. While riding it, Sandrone continuously repairs Fageo by reducing its Calculation Power, effectively resetting the automaton and allowing players to maintain longer combat cycles.

• Her Elemental Burst,
  Phenomenon Formula: All Principles Proven, continues the highly technological theme. Sandrone summons multiple Prismatic Resonance Cannons before unleashing a devastating Subzero Convergence Beam that deals massive AoE Cryo damage. Under Radiance: Stella Superconduct, the beam becomes reaction based damage instead.
  

• The leak also provides extensive details about Sandrone’s passive talents. Her Ascension Passive:
  Eternal Calculation Engine, enhances Prism Shell damage based on Fageo’s Calculation Power while generating stacks called Improved Tactics. These stacks later empower her Elemental Burst, potentially creating an extremely high damage payoff system.
  Meanwhile, another passive called A Lady’s Principles of Conduct converts Sandrone’s ATK into Elemental Mastery, further reinforcing her reaction focused gameplay style.
  

• Perhaps the most important reveal in the entire leak is the full explanation behind Stella Superconduct itself:
  According to the information, whenever party members trigger standard Superconduct, it instead transforms into Stella Superconduct while Sandrone is present in the party.
  This upgraded reaction creates a temporary field known as the Stellar Glow Domain, enhancing Sandrone’s abilities and unlocking special attack conversions across her kit.
  

If accurate, this would make Sandrone one of the first characters in Genshin Impact capable of fundamentally transforming an existing elemental reaction into an entirely new combat mechanic.

Additionally, Sandrone’s leaked constellations appear to massively expand her role as a reaction focused Cryo hypercarry while also improving the stability of her extremely technical combat system. Theorycrafters are already calling her constellation set one of the most synergistic kits leaked so far for Version 6.7.

• Constellation Level 1:
  Gilded Yet Unfaded, Twilight Yet Distant immediately changes the pacing of Fageo’s resource management. By reducing Calculation Power gain speed by 50% during Calculation Mode, Sandrone can remain in her empowered state for much longer before triggering Overclock. This significantly improves combat consistency and allows players to maintain sustained Stella Superconduct pressure across extended encounters. On top of that, the entire party gains a massive 30% increase to Stella Superconduct damage, potentially making Sandrone a powerful enabler even outside of hypercarry teams.

• Constellation Level 2:
  Reflections in the Mirror, Time Dances Gracefully appears to be one of Sandrone’s biggest early power spikes. Every Condensation Ray gains bonus damage scaling directly from Sandrone’s ATK, while repeated ray attacks continuously stack even more additional scaling during the same Calculation Mode cycle. Since the effect stacks up to three times, this constellation heavily rewards players capable of maintaining uninterrupted Calculation Mode uptime and proper resource balancing.

• Constellation Level 3:
  Neither Mourning Sunset nor Envying Moonrise increases the level of Sandrone’s Normal Attack talent by three levels. While this may initially appear less impactful compared to her reaction focused mechanics, it could still significantly boost the damage of her mathematical thread slashes and Charged Attack scaling depending on her final multipliers.

• Constellation Level 4:
  All Things Are Numbers, Days and Nights Pass By further reinforces Sandrone’s identity as a reaction specialist. Whenever she triggers Stella Superconduct damage, she automatically summons an additional Prismatic Resonance Cannon that performs a coordinated Cryo attack based on 125% of her ATK. More importantly, this bonus damage itself counts as Stella Superconduct reaction damage, meaning it likely benefits from all of her reaction multipliers, buffs and passive scaling effects. Since the effect can trigger every four seconds, many players believe this constellation could dramatically increase her off-field pressure and AoE performance.

• Constellation Level 5:
  All Phenomena Turn to Ash, Reason Alone Endures increases the level of Sandrone’s Elemental Burst by three. Because her Burst already scales heavily with Improved Tactics stacks and Stella Superconduct conversion effects, this constellation may represent a substantial direct damage increase for her strongest nuke window.

• Constellation Level 6:
  The Narcissus Awakens, Awaiting Morning Light completely transforms Fageo’s attack pattern into something far more destructive. After firing its third Condensation Ray, Fageo begins continuously unleashing a stronger Clustered Condensation Ray capable of triggering multiple additional AoE Cryo damage instances. Under the Radiance: Stella Superconduct state, these additional hits become reaction based damage scaling directly from Sandrone’s ATK.
  

The constellation also grants a universal 20% increase to all Stella Superconduct damage dealt by Sandrone, potentially making her one of the strongest reaction based DPS characters in the game if the current numbers remain unchanged.

Many players are already comparing Sandrone’s constellation design to some of the most premium modern hypercarry kits because each upgrade directly enhances the flow of her core mechanics instead of feeling disconnected from her gameplay loop. The combination of resource management, reaction amplification and automated cannon attacks creates a combat style that feels unusually advanced compared to older Genshin Impact characters.

Community reactions to the kit have been explosive so far.
Many players are praising the complexity, visual style and mechanical identity of Sandrone’s gameplay, especially compared to more traditional Cryo characters. Others believe the kit feels closer to a futuristic combat system than anything previously seen in Teyvat.

At the moment, none of this information has been officially confirmed by HoYoverse. As with all beta leaks and datamined content, abilities, numbers, reactions and mechanics remain highly subject to change before release.

Still, if these leaks prove accurate, Sandrone could become one of the most technically advanced and mechanically unique characters ever introduced in Genshin Impact.
