In the Huaxu region of Duet Night Abyss, Kezhou is one of the few commanding characters. Kezhou is a Lumino Drifter in Duet Night Abyss, who changes his playstyle between ranged and melee-based close combat. His playstyle is complemented by the right choice of Introns, Demon Wedges, and Weapon selection. Players who master his playstyle are highly rewarded in the game. Players looking for a character with a flow in its playstyle, instead of static growth, should surely build Kezhou as their main character.

Let’s follow LDShop, as we will share about Kezhou’s mechanics, skills, which Introns to prioritize for him, Demon Wedges for him, and the best weapon selection for him in this guide.

Kezhou: Playstyle and Skills

Kezhou’s playstyle is constantly switching between ranged attacks and close-combat melee bursts. He transitions his states from Battery Phase to Discharge Phase, which allows him to have high mobility, and in aspect mode, he gets boosts for his attack speed. Using his skills, he also maintains high damage per second. Alongside the Introns and Demon Wedges, his skills play an important role in his playstyle. His main skills include:

Drift of Youth

It is one of the main skills for Kezhou, as this skill changes the tempo of combat depending on the current state. When the skill is used, it uses up to 50 Lumino to deal damage three times to enemies who are in range, and also increases the attack speed of Kezhou’s Ranged Weapon.

When Kezhou is in the Aspect Manifestation state, which is his Ultimate transformation, this skill increases the attack speed for Kezhou’s Melee Weapon, and Kezhou becomes immune to Hitsun when taking damage. This helps him to face tank enemies easily. The main attribute of this skill is its duration, which is 31.56 seconds. The other attributes include DMG: 162.84% and ATK Speed Boost: 63%.

Lightswords Slice Starry Streams (Ultimate Skill)

It is the ultimate skill, another important skill for any Kezhou build. When the kill is used, Kezhou enters the Aspect Manifestation state and summons Edges of All Times to fall from the sky, dealing Lumino Damage to enemies within range. And when he is in the aspect manifestation state, his melee weapon is transformed into Phanosword, and when this Phanosword is used to trigger bonus effects, it generates Phanoplumes. Kezhou can have 7 Phanoplumes at max; these orbit an enemy and deal Lumino damage to them.  

Life's A Fleeting, Shifting Tide (Passive Skill)

Oscillating between Sword Intent and String Intent is what governs the resource economy for Kezhou’s build. The Sword intent is built when Kezhou uses ranged weapons, and when he uses ultimate to switch to melee weapons, he builds String intent. Using this skill, when the enemies are within a 20-meter range, the resource conversion rate also increases. Sanity is restored when the bonus effect is triggered, which helps the spirit from being completely drained out when Drift of Youth is used.

Introns for Kezhou

There are six Introns for Kezhou, and as we go up each level of these Introns, Kezhou becomes more powerful. To unlock each Intron level, we need 30 Thought: Kezhou.

  • Intron 1: This upgrade increases the effect percentage of Intent conversion. The effect percentage of Sword Intent and String Intent is increased by 0.7% when applied to the passive skill. This makes the transition smoother from ranged to melee.
  • Intron 2: When damage is dealt, and a bonus effect is triggered, this intron provides 90% damage dealt for 5 seconds. This is helpful for Kezhou as he triggers these effects multiple times, which increases the damage significantly. This also restores 2 sanity every second.
  • Intron 3: It increases 2 levels of upgrade for the skill Drift of Youth, and 1 level for the passive skill.
  • Intron 4: When Kezhou uses his ultimate, he gains Blessed by Wind and Moon, by this Intron. He becomes immune to Hitsun, and the damage taken is reduced by 25% for 25 seconds.
  • Intron 5: It increases 2 levels of upgrade for the Ultimate Skill, and 1 level for the passive skill.
  • Intron 6: This is the final Intron, and the final level of power for Kezhou. Kezhou gains 1 stack, which increases his penetration stats by 3% for 18 stacks, which increases the penetration up to 54% for 12 seconds, when the Bonus effect is triggered. This is very helpful for endgame enemies with strong armor.

Among these six Introns, the introns that bring the best out of Kezhou are Intron 1,2,4, and 6.

Demon Wedges

The Demon Wedge system is one of the most important parts of the build. This helps to improve the stats for Kezhou. The Demon Wedges for Kezhou are:

  • Typhon’s Prime Morale: This provides attack, Hp, Defense, and Morale boost.
  • Helio’s Gleam and Glimmer: The most important Demon Wedge in Kezhou’s build. It increases skill duration by 24% and also increases Lumino character’s attack.
  • Griffin's Skylume Midnight Sun: It provides a boost to Lumino attack, Skill Damage, and Skill Duration. This is a very important Demon Wedge, as it increases Lumino ATK and Skill Duration together.
  • Covenanter’s Blaze Eternity: It increases Attack and Skill Duration. On upgrading to +5, this Demon Wedge can be equipped in multiples.
  • Covenanter’s Scorch: Increases Attack and can be equipped in multiples on upgrading to +5.
