If you often find your progress slowed by fragmented playtime or not being able to sit at your PC for long sessions, OSLink can be a huge quality-of-life upgrade. By launching Duet Night Abyss on your home PC and connecting remotely via phone or tablet, you can handle farming, gear adjustments, or team testing anytime, anywhere, greatly improving overall efficiency.

I. Kezhou Overviews
Kezhou is a Lumino main DPS centered on seamless switching between melee and ranged combat. Rather than relying on raw stat checks, his design emphasizes tempo control, stance transitions, and resource flow.
Core Mechanics
Kezhou’s kit revolves around Aspect Manifestation and a dual-resource system: Sword Intent and String Intent. Activating his Ultimate places him into Aspect Manifestation, transforming his melee weapon into Phanosword, which features multiple attack patterns and significantly boosts melee pressure. During this state, his attacks generate Phanoplumes, autonomous projectiles that pursue enemies and maintain constant offensive pressure.
His passive converts melee and ranged attacks into Sword Intent and String Intent respectively, with the two resources continuously transforming into each other based on attack type. As a result, Kezhou must constantly rotate between melee and ranged actions to keep his resource loop active.
II. How to Unlock and Get Kezhou
Kezhou can be obtained by:
- Farming Fushou's Thoughts through Immersive Theatre.
- Purchasing directly from the shop.
After Version 1.1 Phase 2 ends, he will be added to the weekly dungeon.

III. Kezhou Key Introns & Analysis
INTRON I
INTRON I increases the per-point efficiency of both Sword Intent and String Intent, effectively buffing Kezhou’s melee and ranged damage.
More importantly, when facing one or two enemies, the conversion rate between Sword Intent and String Intent increases significantly. This improves Kezhou’s performance in elite and boss encounters, preventing resource stagnation in low enemy count scenarios.
INTRON II
INTRON II is the core of Kezhou’s skill loop. Whenever extra damage is caused, he restores Sanity, with an extremely short internal cooldown of just 0.5 seconds—making it highly reliable in combat.
Because Kezhou’s damage heavily depends on chaining Aspect Manifestation with his Ultimate, Sanity pressure is naturally high. INTRON II significantly reduces downtime, allowing back-to-back ultimates and empowered skills.
INTRON IV
At first glance, it seems to focus on survival, but its true value lies in output stability. After casting his finisher, Kezhou gains damage reduction and full stagger resistance, ensuring his combo flow remains uninterrupted during Aspect Manifestation.
Since Kezhou frequently commits to melee range, this INTRON is invaluable in high-pressure content, preventing enemy chip damage from breaking his rhythm. While it doesn’t directly increase numbers, it massively improves comfort and consistency.
INTRON VI
A straightforward damage Intron: triggering additional damage grants stacking penetration bonuses. Against high-defense enemies, the scaling is especially noticeable.
IV. Demon Wedge Recommendations
Recommended Set:
- Typhon's Prime·Uplift (Lumino)
- Siren's Wings·Inspo
- Griffin's Skylume·Midnight Sun
- Helios's Glimm & Glimmer
- Covenanter's Scorch (Lumino)
- Covenanter's Blaze·Eternity (Lumino)

Demon Wedge Effect Breakdown:
- Typhon's Prime·Uplift (Lumino): Massive base stat increase
- Siren's Wings·Inspo: Increases Sanity cap and skill efficiency
- Griffin's Skylume·Midnight Sun: Boosts Lumino ATK, Skill DMG, and Skill Duration
- Helios's Glimm & Glimmer: Extends Skill Duration and converts it into Lumino ATK
- Covenanter's Scorch (Lumino): Large raw ATK boost
- Covenanter's Blaze·Eternity (Lumino): ATK and Skill Duration increase
V. Weapon Recommendations
Exclusive Weapon
Ephemeral Lumina

Kezhou’s exclusive weapon. Missed shots refund ammo, triggering bonus damage effects that stack ATK. Casting his Ultimate refreshes all stacks, making this weapon perfectly tuned for his rotation-heavy playstyle.
Alternatives
Momiji Itteki

Boosts CRIT DMG and scales damage based on combo count, strong for sustained fights.
Rendhusk

A universal option that increases Skill DMG, reducing reliance on Demon Wedge substats.
VI. Best Team & Geniemon Synergies
Kezhou + Fina + Fushu

- Kezhou’s damage is heavily Ultimate-driven.
- Fushu supplies rapid Sanity recovery to maintain uptime, alongside healing and shields for survivability.
- Fina provides ATK buffs and bonus damage instances, which synergize perfectly with Kezhou’s passive and signature weapon triggers.
Alternate Role

If Fushu is unavailable, Truffle and Filbert can serve as a temporary replacement. Fina, however, is strongly recommended due to how crucial her bonus damage is to Kezhou’s output.
Recommended Geniemon
- Luminelf – Boosts team-wide Lumino damage and adds bonus damage via active skill

- Ballbee – Increases Lumino ATK and amplifies enemy skill damage taken

- Nebuthis – Applies AoE DEF reduction through its active skill

VII. Conclusion
Kezhou ultimately represents a specific kind of main DPS: one that trades simplicity for depth. His damage potential doesn’t come for free—it’s unlocked through smart stance management, efficient resource conversion, and knowing when to commit to aggression or reposition. In the hands of a practiced player, he offers flexible damage profiles, strong scaling, and a very satisfying sense of control over the flow of combat.
During testing and progression, OSLink can significantly ease the grind. By recording dungeon or material-farming scripts on PC and letting them run automatically, you can continue accumulating resources even when away from your desk. Offloading repetitive tasks to OSLink lets you focus on theorycrafting, optimization, and team building, making your overall experience smoother, more efficient, and far less exhausting.
