Sandrone, the Seventh Fatui Harbinger codenamed "The Marionette," is a 5-star Cryo Claymore main DPS who arrived in Version 6.7. She shines in teams built around the new Stellar-Conduct reaction, an upgraded form of Superconduct that mixes Cryo and Electro. Her kit revolves around powerful on-field Charged Attacks, mechanical summons, and big AoE Burst damage while in a special Radiance state.

She excels as a selfish on-field carry who stays on the field for extended periods, dealing consistent high damage through Charged Attacks enhanced by Stellar-Conduct. Her playstyle feels smooth and mechanical, with loops of Charged Attacks supported by her Elemental Skill.

Playstyle and Key Mechanics

Sandrone focuses on her Charged Attack, which lasts several seconds and deals heavy damage. She uses her Elemental Skill to summon a mechanical companion (like a hovermech or cannon) that provides additional support and damage. After a couple of Charged Attack cycles, she unleashes her Elemental Burst for massive AoE payoff.

The core of her power comes from the Radiance: Stellar-Conduct state. This activates inside a Polestar Field created by triggering Stellar-Conduct reactions on enemies. In this state, her Charged Attacks, Skill, and Burst convert to Stellar-Conduct damage with big multipliers. Consistent Cryo and Electro application from teammates keeps the reaction going and maintains her buffs.

She benefits greatly from healers or shielders because she stays on-field and can be interrupted during long Charged Attacks. Energy Recharge helps her Burst come up reliably every rotation.

Talent Leveling Priority

  • Normal Attack (highest priority)
  • Elemental Burst (second)
  • Elemental Skill (lowest, but still worth leveling)

Most of her damage comes from Charged Attacks tied to the Normal Attack talent. The Burst provides huge burst windows, so level it next. The Skill is useful for support damage but contributes the least to her total output.

Best Weapons

Sandrone scales well with ATK, Crit stats, and any Stellar-Conduct or Charged Attack bonuses.

Best in Slot

A Teaspoon of Transcendence (Signature 5-star Claymore)

This is her clear best weapon. It boosts ATK and gives Stellar-Conduct DMG increases on Charged Attack hits that stack up quickly.

Strong Alternatives

  • A Thousand Blazing Suns (5-star) - Excellent Crit Rate and Crit DMG with strong passive uptime on Skill and Burst.
  • Redhorn Stonethresher (5-star) - Solid Crit DMG stat stick.
  • The Unforged (5-star) - Good ATK boost, especially with shield support.
  • Beacon of the Reed Sea or Verdict (5-star options) - Viable stat sticks depending on your roster.

F2P / 4-star Options

  • Tidal Shadow (R5) - Best accessible choice if you have a healer to trigger the passive.
  • Mailed Flower (R5) - Strong if you still have it.
  • Ultimate Overlord's Mega Magic Sword (R5) - Good ATK and ER for Burst uptime.
  • Serpent Spine (R5) - Reliable Crit and DMG bonus.

Best Artifacts

Disenchantment in Deep Shadow (4-piece) is her dedicated set and the clear winner.

Set Effects

  • 2-piece: +18% ATK
  • 4-piece: Boosts Superconduct DMG by 80% and Stellar-Conduct DMG by 40%. Attacks against enemies affected by these reactions gain +16% Crit Rate.

This set directly amplifies her reaction damage and gives free Crit Rate, making it around 20% better than generic options.

Main Stats

  • Sands: ATK%
  • Goblet: Cryo DMG% (or ATK% if better substats)
  • Circlet: Crit Rate or Crit DMG (balance for 1:2 ratio)

Substat Priority

Crit Rate > Crit DMG > ATK% > Elemental Mastery (ER if Burst uptime is an issue)

Aim for a balanced Crit ratio. EM helps a bit with reaction damage but is secondary to Crit and ATK.

Recommended Teams

Premium Stellar-Conduct Team (Highest damage)

Sandrone + Yae Miko + Escoffier + Qiqi

Yae Miko provides reliable off-field Electro. Qiqi offers healing, Cryo application, and Stellar-Conduct buffs. Escoffier adds Cryo damage and buffs. This team keeps reactions flowing perfectly.

Strong Alternative

Sandrone + Yae Miko + Nicole + Qiqi

Nicole brings strong ATK buffs while keeping the core reaction setup.

F2P-Friendly Team

Sandrone + Beidou + Diona + Sucrose

Beidou handles off-field Electro. Diona provides shielding and healing. Sucrose groups enemies and shreds resistance. Very accessible and still effective.

Other flexible options include swapping in characters like Citlali or additional Cryo supports as long as they help maintain the Stellar-Conduct loop.

Quick Rotation Tips

  1. Apply Cryo and Electro to trigger Stellar-Conduct and enter the Polestar Field.
  2. Use Sandrone's Charged Attack loop (2-3 times).
  3. Cast Elemental Skill for mechanical support.
  4. Repeat Charged Attacks.
  5. Use Elemental Burst for big damage when energy is ready.
  6. Swap to supports to refresh buffs and reactions, then return to Sandrone.

Keep her on-field as much as possible while maintaining the Radiance state.

Final Thoughts

Sandrone is a strong and stylish main DPS who rewards teams built around the new Stellar-Conduct reaction. Her signature weapon and dedicated artifact set make her feel very premium, while solid F2P options keep her accessible. Focus on Crit stats, consistent reactions, and a bit of healing or shielding, and she will deliver excellent sustained and burst damage.

Pull for her if you enjoy on-field Claymore carries and want to explore the evolving Cryo-Electro meta. Good luck on your pulls and builds!
