Iuno Best Weapon & Artifacts for 2026
⚡ Why This Build Works
Any 5★ Gauntlet (signature) synergizes with Iuno's kit because it provides the stats they need most. Combined with Moonlit Clouds (5pc) ER + Bell-Borne Geochelone (main echo), this build achieves the best balance of damage output and energy efficiency in the current meta. The main stat priority of Energy Regen / ATK% / CRIT Rate ensures Iuno hits the right damage breakpoints while keeping their rotation smooth.
Build Tips & Optimization
Best Weapon for Iuno in 2026
Any 5★ Gauntlet (signature) is the best-in-slot weapon for Iuno. This weapon maximizes their damage output by synergizing with Aero damage and their kit mechanics. It provides the optimal stat balance — whether that is ER for burst uptime, CRIT for raw damage, or EM for reaction teams.
F2P Weapon Option
Any 4★ Gauntlet (standard) is a strong alternative that performs well without spending primogems on the weapon banner. It provides competitive damage especially at refinement 5. For budget players, this weapon lets Iuno clear most content without sacrificing too much damage — the gap between Any 4★ Gauntlet (standard) and Any 5★ Gauntlet (signature) is usually manageable in endgame content.
Best Artifact Set for Iuno in 2026
Moonlit Clouds (5pc) ER / Bell-Borne Geochelone (main echo) is the recommended set. This set provides the best balance of damage and utility for Iuno in most team compositions. The 4-piece set bonus works directly with their kit to amplify damage, while the 2-piece bonus covers their stat requirements early on.
Stats Priority
- Substats: Energy Regen > ATK% > CRIT Rate > HP% > DEF%
- Main Stats: Energy Regen / ATK% / CRIT Rate
Getting the right main stats is the most important step — a correct main stat with bad substats will always outperform the wrong main stat. Once your main stats are correct, focus on improving substat rolls to optimize Iuno's damage further.
Rotation Guide
Build Concerto fast -> Outro to hand the Heavy-Attack / Aero buff -> swap to the carry. Keep her off-field after setup.
Practicing this rotation is essential. Iuno relies on proper ability ordering to snapshot buffs, maintain uptime, and maximize their damage window. Watch your energy gauge and swap back to supports before Iuno's buff window expires.
Common Mistakes When Building This Character
- Using wrong main stat on artifacts — stat priority beats set bonus in most cases.
- Ignoring Energy Recharge requirements — not enough ER breaks the rotation.
- Copying whale builds — most guides assume 5-star weapons and high constellations.
- Over-investing in ATK when the character scales with HP, DEF, or EM instead.
- Not leveling the right talents first — some talent upgrades are trap investments.
- Neglecting the team — Iuno performs best in Iuno + Cartethyia / Jiyan + Shorekeeper / Verina., so build around their support needs.
