Sandrone dropped in Genshin Impact version 6.7 on July 1, 2026, as the first playable character to run on the new Stellar Conduct reaction. She’s a 5 star Cryo claymore user, and she’s also the seventh Fatui Harbinger, known in game lore as the Marionette.

If you play Cryo teams or you’ve been sitting on Primogems waiting for a real Superconduct rework, this is the patch that matters. Stellar Conduct replaces the old, mostly useless Superconduct damage with a stacking system that buffs your whole team’s Cryo and Electro output, on top of Sandrone’s own huge beam attacks. Below, we cover her kit in plain terms, the artifacts and weapons that actually work, and the teams worth building around her.

What Stellar Conduct actually does in a fight

Cryo and Electro colliding used to trigger Superconduct, a small, mostly forgettable hit that shredded Physical resistance and not much else. Stellar Conduct keeps the resistance shred but adds a stacking system on top of it.

Every few seconds, the reaction counts how many times Cryo and Electro landed on nearby enemies and turns that into stacks, up to 12 max. Those stacks pump up a separate damage type called Stellar Conduct damage, and they also buff straight Cryo and Electro damage for your whole party while the effect is active. Community translations of the reaction’s damage formula show it scales off Attack, Crit stats, and Elemental Mastery, and it skips right past enemy defense, similar to how Nightsoul or Lunar reaction damage already worked in recent patches.

How Sandrone’s kit uses that reaction

Sandrone’s normal attacks aren’t the point. Her charged attack deploys Fagio, a small drone that fires a burst of shots followed by a big beam, and Fagio’s beams are where most of her damage comes from once Stellar Conduct stacks are up.

Her Elemental Skill refreshes Fagio so it can keep firing, and using it while Fagio still has some charge left triggers a much bigger hit. Her Burst fires several Cryo hits plus one large Stellar Conduct beam, and that beam hits twice as hard if you’ve properly cycled her skill beforehand. In short, her loop is charge, refresh, charge again, then burst when the timing lines up, and the rotation can run almost nonstop as long as your team keeps applying Electro.

Who this actually helps, and who’s stuck on the bench

Cryo mains finally get a main DPS that doesn’t just rely on Freeze setups. Electro support units like Yae Miko and Beidou also jump in value, since keeping Electro uptime is the whole job for Sandrone’s fourth team slot.

Pure Freeze comps built around older Cryo carries take a slight backseat here, since Stellar Conduct wants steady Electro application, not just Cryo stacking. If your account is light on strong off field Electro units, Sandrone will feel weaker than the build guides suggest, so that’s the gap to fix first.

Best artifacts and stats for Sandrone

Disenchantment in Deep Shadows is the set to farm. Its four piece bonus boosts Superconduct/Stellar Conduct reaction damage and adds fifteen plus percent bonus Crit Rate against enemies affected by it, which lines up perfectly with her kit.

While you farm that set, Gilded Dreams or a mixed two piece Attack and two piece Elemental Mastery combo works fine as a placeholder. For main stats, go Attack% on the sands and goblet (Cryo goblet actually underperforms here since Stellar Conduct damage ignores elemental bonus damage), and Crit Damage on the circlet, since her passive, the set, and Cryo resonance already push her Crit Rate high on their own.

Weapons that make or break her damage

Her signature claymore, A Teaspoon of Transcendence, is the clear best option, adding Crit Damage, flat Attack, and a stacking Stellar Conduct damage bonus through her charged attacks. A Thousand Blazing Suns is a strong second choice if you don’t pull her weapon.

For free to play accounts, Tidal Shadow is genuinely solid, since it rewards Attack when Sandrone gets healed, something teams with Qiqi or Diona do naturally anyway. Skip weapons loaded with Crit Rate as a secondary stat, like Serpent Spine or Beacon of the Reed Sea, since she’ll blow past 100% Crit Rate and waste the extra stat entirely.

Team comps worth building around her

Every Sandrone team needs one thing above all else: an Electro unit that applies Electro every four to five seconds from off field. Cryo resonance is a nice bonus for the extra Crit Rate, but it isn’t mandatory.

A strong starting point is Sandrone, Yae Miko, Qiqi, and Sucrose, since Yae keeps Electro flowing constantly and her Burst alone can load up several stacks at once. A cheaper, F2P friendly version swaps in Fischl and Diona instead, trading a bit of stack consistency for accessibility. If you’re running a triple Cryo core for the resonance bonus, keep your Electro applicator’s uptime as the top priority when picking gear.
