Kezhou’s Playstyle and Kit

Kezhou functions as a "hyper-carry" whose power is gated by a tidal combat loop. His gameplay revolves around the "Aspect Manifestation" state, a metaphysical transformation that replaces standard melee strikes with the Phanosword. This kit punishes stagnation and rewards constant motion, as players must navigate a resource economy that forces them to move between melee and ranged engagement to sustain their offensive pressure. It is this unique duality that defines the meta-viability of Duet Night Abyss Kezhou.

Kezhou’s First Skill: Drift of Youth

Drift of Youth is the foundational engine of his kinetic potential. In its neutral state, it deals Lumino Damage and increases Ranged Weapon Attack Speed, making even heavy rifles feel surprisingly snappy. However, once Kezhou enters his transformation, this buff transposes its efficacy to Melee Weapon Attack Speed, scaling up to a massive 75% boost at maximum proficiency. Crucially, it provides total immunity to Hitstun during this window, ensuring that micro-flinches from enemy fire never reset your combo strings.

Kezhou’s Ultimate Skill: Lightswords Slice Starry Streams 

The tactical apex of his kit is Lightswords Slice Starry Streams. Activating this skill consumes 100 Sanity to trigger the Aspect Manifestation state, where his equipped melee weapon becomes the Phanosword. This weapon gains a 1-meter range extension and spawns autonomous Phanoplumes—projectiles that pursue targets independently while you focus on your primary target. The sequence concludes with Feathers Chase Dust in Dreams, a finisher dealing up to 2107% damage, punctuating the rotation with a massive kinetic release.

Kezhou’s Passive Ability: Life's A Fleeting, Shifting Tide

The "Intent" mechanism acts as the governor of his efficiency. Melee interactions build "Sword Intent," which reduces the cost of his Ultimate, while ranged combat builds "String Intent" to empower his finisher. This creates a reciprocal relationship: you engage at range to fuel the melee transformation, then engage in melee to fuel the next ranged burst. Neglecting one-half of this tidal flow results in a significant decay of your total DPS potential.

Best Intron Upgrades for Kezhou: What Level Should You Target?

While functional at Intron 0, the power curve for Duet Night Abyss Kezhou is steep, with specific breakpoints offering disproportionate returns on investment. Targeting I6 is the definitive goal for endgame players.

• Intron 1: Normalizes Intent conversion rates, making rotations consistent even in single-target boss fights.
• Intron 2: Triggering a bonus effect grants a staggering 90% Damage increase and restores Sanity every second, effectively extending the duration of his transformation.
• Intron 4: Grants the Blessed by Wind and Moon status, providing 25% Damage Reduction and Hitstun immunity, allowing you to ignore enemy mechanics to finish your rotation.
• Intron 6: This is the meta-defining upgrade. Triggering bonus effects stacks Penetration (PEN) by 3% per instance, up to a maximum of 54% PEN. This makes him the ultimate tank buster in high-tier content.

The Optimal Demon Wedge Loadout for Kezhou

Constructing a top-tier Kezhou build requires a duration-conversion strategy rather than traditional set-stacking. The goal is to maximize the length of his buffs and convert that time into raw offensive stats. 

The cornerstone of this setup is Griffin's Skylume · Midnight Sun, which boosts Lumino ATK and Skill Duration. You then pair this with Helios's Gleam & Glimmer, a wedge that converts your current Skill Duration into a Lumino ATK buff of up to 19.5%. To sustain this, Siren's Wings · Inspo is essential for increasing your Sanity cap, while Typhon's Prime · Morale supplies the raw base stats needed for your multipliers to scale effectively.

Best Weapon Combos for Kezhou

Weapon selection for Duet Night Abyss Kezhou is governed by a peculiar mechanic: during his Ultimate, melee weapon passives—like unique triggers—do not function. Only raw stat sticks like Crit and ATK truly matter.

• Aureate Yore (Melee BiS): At Smelt 3+, this offers the highest raw stat ceiling and mathematical floor for his Phanosword strikes.
• Vernal Jade Halberd (F2P Melee): A fantastic alternative whose materials are easily purchasable, providing high mobility via the Piercing Ascent wedge.
• Ephemeral Lumina (Ranged BiS): This is the ideal partner because its secondary stat provides Skill Duration, directly feeding the conversion engine mentioned above.

Best Team Composition For Kezhou 

Creating the perfect DNA Kezhou build requires a team that can fuel his Sanity and amplify his elemental output. The current gold standard is the trio of Kezhou, Fina, and Fushu. Fina is a must-have Lumino support, providing a flat 50% ATK buff to the team and additional damage instances that trigger on every fast strike Kezhou lands. Fushu serves as the backbone of the rotation, supplying the rapid Sanity recovery and shields necessary to maintain permanent uptime on his Aspect Manifestation state.

How to Play Duet Night Abyss on PC or Mac with MuMuPlayer

The mechanical ceiling for this DNA Kezhou build is incredibly high, and touch controls often fail to capture the precision needed for his high-speed rotations. To get the edge in high-stakes combat, you need to ditch your mobile and play the game on PC using MuMuPlayer. Utilizing MuMuPlayer is the best way to truly master the movements of Duet Night Abyss Kezhou on a professional level.
