Cyno Build & Teams: 5-Star Electro Polearm Carry & Aggravate Core

How Cyno Works

Cyno is a "long on-field + fastest melee attack speed" carry:

• Burst enters Initiator's Oath: Normal/Charged/Plunging all become un-overridable Electro, lasting ~18s, can't swap out during it.
• Empowered state grants knockback immunity + Electro-Charged immunity, making on-field safer.
• Very high attack frequency → triggers Aggravate with Dendro + Electro application, or Quickbloom with Hydro.
• The Skill can be cast mid-Burst when the purple prompt appears to land the empowered multi-hit — his main output input.

Artifacts

Set	2pc	4pc
Gilded Dreams	+80 EM	EM to same-element / ATK to different-element teammates — best for reaction carry, covers Aggravate and Quickbloom
Thundering Fury	+15% Electro DMG	+40% Charged/Aggravate/Superconduct/Hyperbloom; after triggering, E CD −1s (once/0.8s)
Gladiator's Finale	+18% ATK	+35% Normal/Charged DMG — on-field DPS placeholder

Main & Sub Stats

Slot	Main Stat
Sands	Elemental Mastery (reaction preferred) / ATK%
Cup	Electro DMG Bonus / Elemental Mastery
Circlet	Crit Rate / Crit DMG

Sub-stat priority: Energy Recharge (keep Burst cycling; 80-energy cost) > Crits > EM > ATK. Dual-Electro teams ease the ER pressure; solo Electro needs 120–140%.

Weapons

Weapon	Rarity	Notes
Staff of the Scarlet Sands	5★	Converts EM into damage; best-in-slot for reaction Cyno
Serpent Spine	5★	ATK% + RES shred; general 5★ alternative
Kitain Cross Spear	4★	Crafted; ER + EM, top F2P pick

Team Comps

Aggravate Team (most reliable)

Cyno (DPS) + Nahida (Dendro/EM) + Fischl (off-field Electro) + Kazuha/Baizhu (grouping/shield)

• Nahida applies Dendro + Fischl's Oz applies Electro → target stays Quicken'd.
• Cyno's on-field hits trigger Aggravate constantly; Gilded Dreams amplifies it.
• Baizhu's shield resists interruption; Kazuha swirls and shreds Electro RES.

Quickbloom Team (best single-target)

Cyno (DPS) + Nahida (Dendro) + Xingqiu (Hydro) + Raiden/Kuki Shinobu (trigger/ER)

• Xingqiu applies Hydro + Nahida applies Dendro → Dendro Cores spawn.
• Raiden/Kuki Shinobu apply Electro → Cores turn Quickbloom.
• Cyno's on-field window cashes in both Quickbloom and his own Aggravate.

Constellation Priority

• C2: Normal hits stack +10% Electro DMG (max 5 stacks) — the biggest on-field upgrade, top value.
• C1: +20% ATK Speed in the empowered state, higher reaction trigger rate.

FAQ

Is Cyno Electro or Dendro?

His element is Electro (Electro Resonance; can trigger Charged/Superconduct/Aggravate). He's a Sumeru character but since 4.x plays as an Electro polearm carry. Teams revolve around "he applies Electro + teammates apply Dendro/Hydro."

Is Cyno worth pulling now?

Yes — he has the fastest melee attack speed in the game, scaling both Aggravate and Quickbloom. The tradeoff is needing a Dendro + Electro (or Hydro) setup plus interruption resistance.

Should Cyno prioritize EM or Crits?

Crits are the on-field damage engine; EM amplifies reactions. Main EM Sands preferred (even better with his signature weapon), Crit Circlet, Crit substats to finish.

Why can't Cyno swap out after his Burst?

The empowered state lasts ~18s; swapping cuts the reaction chain. Run persistent off-field abilities (Fischl's Oz, Xingqiu's Rain, Nahida's field), especially in multi-wave content.

How much Energy Recharge does Cyno need?

His Burst costs 80 energy. Solo Electro needs 120–140%; dual-Electro Resonance drops it to ~120%. Serpent Spine / Kitain Cross Spear ER substats help.
