Arlan Best Weapon & Artifacts for 2026
⚡ Why This Build Works
A Secret Vow (signature alt) synergizes with Arlan's kit because it provides the stats they need most. Combined with Pioneer Diver in the Interstellar Sea (4pc) + Rutilant Arena (Planar), this build achieves the best balance of damage output and energy efficiency in the current meta. The main stat priority of CRIT Rate / Lightning DMG / ATK% ensures Arlan hits the right damage breakpoints while keeping their rotation smooth.
Build Tips & Optimization
Best Weapon for Arlan in 2026
A Secret Vow (signature alt) is the best-in-slot weapon for Arlan. This weapon maximizes their damage output by synergizing with Lightning 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
On the Fall of an Aeon (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 Arlan clear most content without sacrificing too much damage — the gap between On the Fall of an Aeon (R5) and A Secret Vow (signature alt) is usually manageable in endgame content.
Best Artifact Set for Arlan in 2026
Pioneer Diver in the Interstellar Sea (4pc) / Rutilant Arena (Planar) is the recommended set. This set provides the best balance of damage and utility for Arlan 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: CRIT Rate > CRIT DMG > ATK% > Speed
- Main Stats: CRIT Rate / Lightning DMG / ATK%
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 Arlan's damage further.
Rotation Guide
Keep HP low via shielder -> Skill/Ultimate for burst -> manage HP.
Practicing this rotation is essential. Arlan 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 Arlan'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 — Arlan performs best in Arlan + Fu Xuan + Bronya., so build around their support needs.
