Cyno changed roles with the Version 6.7 buffs that pushed him toward the Stellar-Conduct reaction. His attacks scale off both ATK and Elemental Mastery, so the best setup stacks Elemental Mastery while still feeding him ATK and crit, then pairs him with a character who can turn Superconduct into Stellar-Conduct. Below is exactly what to equip and who to bring.
Quick answer: Give Cyno the Staff of the Scarlet Sands and the 4-piece Disenchantment in Deep Shadow set, run Elemental Mastery on the Timepiece and Goblet with a Crit circlet, and place a Stellar-Conduct enabler like Odette (or Cryo Traveler for free-to-play) on the team.
Best weapons for Stellar-Conduct Cyno
The whole point of Cyno’s weapon choice is to solve his split scaling. He wants Elemental Mastery to amplify reactions, but he also needs ATK and crit to hit hard. The right Polearm lets you pour Elemental Mastery into the rest of his build without starving his damage.
| Weapon | Base ATK / Secondary | Why it works |
|---|---|---|
| Staff of the Scarlet Sands | 542 ATK / 44.1% Crit Rate | Converts a large share of Elemental Mastery into bonus ATK, so you can stack Elemental Mastery freely and still hit hard. Also the highest crit value of any Polearm. |
| Primordial Jade Winged-Spear | 674 ATK / 22.1% Crit Rate | High base ATK, a crit substat, and stacking ATK% plus a 12% damage bonus at max stacks that Cyno reaches quickly in one rotation. |
| Song of the Vigil (F2P) | 565 ATK / 110 Elemental Mastery | A solid free replacement. Triggering a reaction regenerates energy, and a Stellar Glimmer reaction raises ATK, smoothing out his rotations. |
Staff of the Scarlet Sands is the clear best because it grants ATK based on Elemental Mastery on top of its huge crit rate. That double-dipping is what makes it his signature pick. If you don’t have it, the Primordial Jade Winged-Spear stays close behind, and Song of the Vigil covers the free-to-play slot well.
Best artifacts and stats
Disenchantment in Deep Shadow is the set that turns Cyno into a dedicated Stellar-Conduct enabler. Gilded Dreams still works for his older Aggravate playstyle, but for a Stellar-Conduct focus this set amplifies the reaction directly while feeding him ATK and crit.
| Set bonus | Effect |
|---|---|
| 2-piece | ATK +18% |
| 4-piece | Superconduct DMG +80% and Stellar-Conduct DMG +40%. Attacking targets affected by Superconduct or Stellar-Conduct raises that attack’s Crit Rate by 16%. |
For main stats, lean into Elemental Mastery on the two flexible slots and finish with crit on the head.
| Slot | Main stat |
|---|---|
| Timepiece | Elemental Mastery |
| Goblet | Elemental Mastery |
| Circlet | Crit Rate or Crit DMG |
Prioritize substats in this order: Crit DMG, then Crit Rate, then Elemental Mastery, then ATK%. Keep enough Energy Recharge to reliably cast his Burst; his Stellar-Conduct teams need less than his older builds, but he still wants near-permanent uptime.
Best teams for Cyno
Cyno is an on-field main DPS who drives his team’s reactions while he holds the field. To reach Stellar-Conduct he needs a teammate who converts Superconduct into the reaction. Everything else is built around keeping that loop running and stacking buffs on top.
Cyno + Odette + Ineffa + Columbina
Odette enables and amplifies Stellar-Conduct, giving Cyno his core reaction partner. Ineffa and Columbina add Lunar-Charged reactions that surprisingly line up with Cyno’s kit, letting him trigger both Lunar-Charged (from that pair) and Stellar-Conduct (from Odette). It’s a more varied comp than a standard Electro lineup, and it delivers real damage. You can swap in buffers such as Beidou, Yae Miko, Alyosha, or Qiqi if you lack any of these units.
Cyno + Cryo MC + Alyosha + Diona (free-to-play)
Cryo Traveler replaces Odette as a free enabler, transforming Superconduct into Stellar-Conduct and buffing Cyno’s damage on the reaction. Alyosha adds off-field Electro application that helps Cyno trigger more Stellar-Conduct while dealing his own reaction damage. Diona rounds it out, and at C6 she amplifies Stellar-Conduct and grants Cyno 200 Elemental Mastery while he stands in her Burst field.
Constellation priority
If you’re chasing constellations, target them in this order: C1, then C6, then C2, then C4. C1 and C6 carry the most value, C2 is a strong follow-up, and C4 is more of a supportive stepping stone.
| Constellation | Effect summary | Value |
|---|---|---|
| C1 – Ordinance: Unceasing Vigil | Boosts Normal Attack speed after his Burst, and when he enters Pactsworn Pathclearer he gains Together We Rise for +200 Elemental Mastery, which transfers to the incoming character on swap. | Priority |
| C6 – Raiment: Just Scales | Grants stacks of Day of the Jackal that fire Duststalker Bolts on Normal Attack hits, upgraded to Duststalker Bolt – Starsame while under Together We Rise. | Priority |
| C2 – Ceremony: Homecoming of Spirits | Normal Attacks add up to 50% Electro DMG Bonus, and characters under Together We Rise gain up to 16% Stellar-Conduct DMG. | High |
| C4 – Austerity: Forbidding Guard | Restores party energy when Cyno triggers listed reactions in his Burst state, and allies under Together We Rise regenerate energy for Cyno. | Medium |
Put it together and Cyno’s strongest setup is straightforward: Staff of the Scarlet Sands, 4-piece Disenchantment in Deep Shadow, double Elemental Mastery main stats, crit substats, and a Stellar-Conduct enabler locked into the team. From there, the flexibility comes from which buffers and reaction partners you own, whether that’s the Odette lineup or the free Cryo Traveler build.
