Xiao remains one of the most resilient hypercarries in the current meta. While the game has evolved significantly by 2026, his core identity as a high-frequency plunging DPS is stronger than ever thanks to dedicated supports and newer artifact sets that have effectively raised his damage ceiling. Maximizing Xiao requires more than just high CRIT stats; it involves a precise balance of Energy Recharge, team synergy, and understanding the nuances of his latest best-in-slot gear.

The Shift to Long Night's Oath

For a long time, Vermillion Hereafter was the undisputed king for Xiao builds. However, the introduction of the Long Night's Oath set has shifted the balance for those looking to min-max their plunge damage.

Why Long Night's Oath Works

The 2-piece bonus provides a flat 25% increase to Plunging Attack DMG. The 4-piece set bonus, "Radiance Everlasting," triggers when a character hits an opponent with a plunging attack, charged attack, or elemental skill. Each stack increases plunging damage by 15%, stacking up to five times. Given Xiao’s gameplay loop—skill into burst followed by continuous plunging—he maintains maximum stacks for almost the entire duration of his Bane of All Evil state.

Comparison with Vermillion Hereafter

Vermillion Hereafter focuses heavily on ATK%. While ATK is vital, the massive DMG% bonus from Long Night's Oath often scales better in high-end teams where ATK buffs are already being provided by Bennett or Noblesse Oblige users. If you already have a god-tier Vermillion set with 40+ CV on every piece, the marginal gain from switching might not justify the resin cost. However, for players starting a fresh build or looking for that extra 5-8% performance boost, Long Night's Oath is the superior choice.

The Marechaussee Hunter Alternative

In teams featuring Furina, the 4-piece Marechaussee Hunter remains an incredibly competitive and resin-efficient option. The 36% CRIT Rate bonus allows you to focus almost entirely on CRIT DMG and ATK% substats. It simplifies the building process significantly, though it locks Xiao into a Furina-dependent team composition to ensure the HP fluctuation stacks remain active.

Essential Weapon Rankings for 2026

Xiao’s weapon options have expanded, but the hierarchy remains relatively stable at the top, with a few new contenders for F2P and low-spender players.

1. Primordial Jade Winged-Spear (PJWS)

This remains the definitive signature weapon. It provides a high Base ATK (674), CRIT Rate, and a ramping ATK% and DMG% passive that perfectly aligns with Xiao’s field time. In longer fights, especially in the later chambers of the Spiral Abyss, the consistency of PJWS is hard to beat.

2. Staff of Homa

Staff of Homa is the best alternative for raw damage, especially if you can consistently stay below 50% HP. Even without the low-HP passive, the 66.2% CRIT DMG and the ATK bonus based on Max HP make it a powerhouse. When paired with Xianyun, the high CRIT DMG scaling becomes even more valuable as her flat damage buff benefits from your CRIT multipliers.

3. Fractured Halo

A newer addition to the polearm roster, Fractured Halo offers a unique niche for plunge-focused characters. It provides a significant boost to Plunging Attack CRIT DMG and helps slightly with Energy Recharge upon hitting multiple enemies. It is currently the strongest non-limited 5-star option for those who missed the PJWS banners.

4. High-Value 4-Star Options

  • Deathmatch: Still the go-to for Battle Pass users. The CRIT Rate is massive, making it very easy to balance your artifacts.
  • Lithic Spear: At Refinement 5 and in a Liyue-heavy team (Xiao, Xianyun, Zhongli), this weapon can actually outperform some R1 5-star spears.
  • Blackcliff Pole: The best F2P option available through the shop. While the passive is situational (useless against single-target bosses), the CRIT DMG substat is vital for a hypercarry.

Optimal Stat Thresholds and Substats

Building Xiao is an exercise in resource management. You need enough energy to burst on cooldown, but enough offensive stats to make those bursts count.

Energy Recharge (ER) Requirements

This is where most Xiao builds fail. A Xiao that cannot burst is a Xiao that deals zero damage.

  • With Faruzan (C6) and Xianyun: 120% - 130% ER.
  • With only one Anemo battery: 140% - 150% ER.
  • Triple Anemo teams: 110% - 120% ER.

CRIT Ratio and ATK

  • CRIT Rate: Aim for 80%+. Xiao attacks relatively slowly compared to Ayato or Cyno; missing a CRIT on a high-multiplier plunge is a massive DPS loss.
  • CRIT DMG: 180% is the baseline, with 220%+ being the goal for endgame builds.
  • ATK: 2,000 to 2,400 is the sweet spot. Anything significantly lower will make your CRITs feel underwhelming.

Talent Priority and Gameplay Nuances

  1. Normal Attack: Whirlwind Thrust: This is your most important talent. Despite the damage occurring during his Burst, the Plunging Attack multipliers are scaled off his Normal Attack talent level. Triple crowning Xiao is highly recommended, but if you are short on materials, this comes first.
  2. Bane of All Evil (Burst): This provides the DMG% conversion and increase. It should be leveled alongside his Normal Attacks.
  3. Lemniscatic Wind Cycling (Skill): While it does good damage, its primary role is energy generation. Level it last.

The "Jet" Combo

To maximize single-target damage, use the "Jet" combo: Normal Attack (N1) -> Charged Attack (CA) -> Jump -> Plunge. This animation canceling allows you to squeeze in more damage than just spamming plunges. For AOE situations, simple high-plunge spam remains the most effective way to clear mobs.

The "Premium" Xiao Team Comp

The current gold standard for Xiao is the "Hyper-Plunge" core. This team provides everything Xiao needs: resistance shred, flat damage buffs, healing, and damage amplification.

Xiao + Faruzan + Xianyun + Furina

  • Faruzan (ideally C6): She is the most important support for Xiao. She provides Anemo RES shred, Anemo DMG bonus, and at C6, a significant amount of Anemo CRIT DMG and grouping.
  • Xianyun: She revolutionized Xiao’s gameplay. Her flat DMG buff to plunging attacks is added before CRIT multipliers, making high CRIT stats on Xiao even more explosive. She also provides the team-wide healing necessary to stack Furina’s Fanfare.
  • Furina: Her elemental burst provides a massive universal DMG% buff that ramps up as the team's HP changes. Since Xiao naturally loses HP and Xianyun heals it back, Fanfare stacks are generated almost instantly.

Budget and Comfort Alternatives

If you lack the premium units, Xiao is flexible enough to work with older archetypes:

  • Double Anemo / Double Geo: Xiao, Faruzan, Zhongli, Albedo (or Chiori). This offers unparalleled comfort and protection via Zhongli's shield.
  • Bennett Sunfire / Classic: Xiao, Faruzan, Bennett, Xiangling. This provides massive ATK buffs and off-field Pyro damage, though it restricts you to Bennett’s circle.

Managing HP and Survivability

Xiao is a glass cannon. While in his Yaksha Mask state, he continuously drains his own HP. In 2026's aggressive combat environments, having a reliable healer or shielder is not optional. If you are not running Xianyun, a high-investment Bennett or Jean is required.

One trick to remember: Xiao’s plunging attacks can be used to dodge certain ground-based shockwaves (a common mechanic in recent boss designs). Learning the rhythm of enemy attacks allows you to stay in the air when a ground hit is coming, effectively using your offense as a form of defense.

Final Optimization Tips

  • Pre-Funneling Energy: Always use Xiao's Elemental Skill (two charges) immediately before activating his Burst. If you do it fast enough, Xiao will catch the Anemo particles while already in his Burst state, giving you a head start on the next rotation.
  • Artifact Transmuter: If you are struggling to get an Anemo DMG Goblet for the Long Night's Oath set, use the Artifact Transmuter items from the latest regions to guarantee the main stat. Anemo DMG is almost always superior to ATK% goblets unless your ATK% piece has significantly better substats (e.g., 20% more CRIT DMG).
  • Substat Efficiency: Don't ignore flat ATK or minor ER rolls. While CRIT is the star, Xiao’s high base stats mean he benefits from almost every offensive roll on your gear.

By following this build path, Xiao can comfortably clear Level 100+ content and remain a top-tier choice for any player looking for a high-skill, high-reward Anemo hypercarry.
