Build Tips & Optimization
Best Weapon for Luka in 2026
Resolution Shines As Pearls of Sweat (signature) is the best-in-slot weapon for Luka. This weapon maximizes their damage output by synergizing with Physical 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
A Secret Vow (R5) 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 Luka clear most content without sacrificing too much damage — the gap between A Secret Vow (R5) and Resolution Shines As Pearls of Sweat (signature) is usually manageable in endgame content.
Best Artifact Set for Luka in 2026
Prisoner in Deep Confinement (4pc) / Space Sealing Station (Planar) is the recommended set. This set provides the best balance of damage and utility for Luka 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: ATK% > Effect Hit Rate > Speed > CRIT
- Main Stats: ATK% / Physical DMG / Effect Hit 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 Luka's damage further.
Rotation Guide
Skill to apply Bleed -> Ultimate for more -> Basic to maintain.
Practicing this rotation is essential. Luka 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 Luka'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 — Luka performs best in Luka + Seele + Fu Xuan., so build around their support needs.
