The main stat priority of Energy Regen / ATK% / Ice DMG ensures Soukaku hits the right damage breakpoints while keeping their rotation smooth.
Build Tips & Optimization
Best Weapon for Soukaku in 2026
Fusion Compiler is the best-in-slot weapon for Soukaku. This weapon maximizes their damage output by synergizing with Ice 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
Lunar Plenitude 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 Soukaku clear most content without sacrificing too much damage — the gap between Lunar Plenitude and Fusion Compiler is usually manageable in endgame content.
Best Artifact Set for Soukaku in 2026
Astral Voice (4pc) / Freedom Blues (2pc) is the recommended set. This set provides the best balance of damage and utility for Soukaku 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% > Impact
- Main Stats: Energy Regen / ATK% / Ice DMG
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 Soukaku's damage further.
Rotation Guide
Defensive Assist -> hold Skill to buff the team -> swap to your Ice DPS.
Practicing this rotation is essential. Soukaku 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 Soukaku'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 — Soukaku performs best in Soukaku + Ellen Joe + Lycaon., so build around their support needs.
