Reliable leakers have dropped what many are calling the complete kit for Sandrone ahead of her debut in version 6.7. The seventh Fatui Harbinger, codenamed the Marionette, arrives as a 5 star Cryo Claymore user built around high skill charged attack gameplay and a brand new reaction system designed to shake up Electro and Cryo teams.
Sandrone’s design ties directly into her lore as a master puppeteer and engineer. She appears alongside her massive automaton companion Pulonia in official artwork, and leaks suggest her kit leans heavily into mechanical and reaction based mechanics that fit her Snezhnaya origins.
Basic Information
- Rarity: 5 star
- Element: Cryo
- Weapon: Claymore
- Role: On field main DPS
She is positioned as a gauge managing laser DPS who thrives in teams built around the new Stellar Superconduct reaction.
Charged Attack: Laser Barrage
Sandrone’s core gameplay loop centers on her charged attack. She channels continuous laser beams that deal Cryo damage over time. At set intervals the lasers also trigger Stellar Superconduct damage instances. A heat gauge builds while the attack is active. Once the gauge fills completely Sandrone overheats and the barrage stops, requiring players to pause and reset. Movement speed during the laser is slower than Neuvillette’s charged attack, adding a deliberate pacing element that rewards good positioning and timing.
Elemental Skill
The skill serves as a gauge management tool. It reduces the heat buildup rate or speeds up recharge time for the charged attack while also dealing a single strong instance of Stellar Superconduct damage to nearby enemies. Some early leaks mention possible turret or piloting interactions with Pulonia, but the primary function remains supporting sustained laser uptime.
Elemental Burst
Sandrone’s burst delivers two quick damage ticks: one Cryo instance and one Stellar Superconduct instance. It is expected to interact with the reaction field and may help reset or enhance the gauge system for extended combos.
Stellar Superconduct: The New Reaction Mechanic
This is the standout feature of Sandrone’s kit. Triggering Stellar Superconduct with Cryo and Electro applications creates a special field. Inside the field only characters who can deal Stellar Superconduct damage may output that type of damage. Other Electro and Cryo characters standing in the area gain a 38 percent damage bonus to their respective elements. The mechanic is described as Snezhnaya’s answer to more dynamic reaction play, potentially reviving older units and enabling hybrid team compositions.
Constellations
Leaks outline several power spikes at higher constellations:
- C1 slows gauge buildup and adds a Stellar Superconduct damage bonus.
- C2 provides an ATK buff and improves reaction scaling.
- C4 adds extra Stellar Superconduct instances to the laser beams periodically.
- C6 delivers multiple extra reaction hits inside the field or additional Cryo damage outside it, with further bonuses once certain stacks are active.
Community consensus points to C2 as a strong stopping point for most players while C6 feels genuinely broken for dedicated mains.
Signature Weapon and Team Building
Her signature weapon is rumored to offer high base ATK, substantial crit damage, and passives that boost Stellar Superconduct output while restoring energy. Early damage calculations even show certain standard banner claymores like Wolf’s Gravestone performing competitively in specific teams.
Recommended teammates include strong Electro applicators such as Fischl, Raiden Shogun or upcoming Snezhnaya supports. Cryo buffers like Shenhe or Escoffier benefit heavily from the 38 percent field bonus. Shredders such as Xilonen and general ATK buffers round out the comps. Future units like Vodyanitsa are already being eyed as perfect partners.
