Duet Night Abyss: Lady Nifle Ultimate Guide

Hey Phoxhunters! Looking for a build guide for Lady Nifle? You're in the right place!

Lady Nifle is a highly distinctive Lumino elemental DPS character in Duet Night Abyss. She is renowned for her unique dual-skill switching mechanism between "Lunar Hunt" and "Solar Eclipse", as well as her game-changing ultimate ability, "Misty Sea Requiem".

While her initial role leans towards support, upon reaching the crucial Intron Level 6, she transforms completely into a relentless damage-dealing machine, excelling at both clearing mobs and taking down massive bosses. Today, LDShop provides a comprehensive analysis of this character's mechanics, equipment, and team compositions to help you easily conquer all types of high-difficulty content.

Character Mechanics / Intron Levels (Must reach I6!!!)

Lady Nifle's strength is closely tied to her Intron Levels, with Intron Level 6 being the core transformative point.

Skill - Lunar Hunt / Solar Eclipse: The Umbro-attributed [Lunar Hunt] reduces Movement Speed on hit, while the Lumino-attributed [Solar Eclipse] reduces Attack on hit. These are her core damage skills. In their normal state, they have a smaller area of effect and lower multipliers, making them most effective when used during her ultimate ability state. The Movement Speed reduction from [Lunar Hunt] and Attack reduction from [Solar Eclipse], combined with the enhanced range from the ultimate, make her perform exceptionally well in group scenarios.

Ultimate - Misty Sea Requiem: This is her core skill. It grants [Lunar Hunt] a crowd-pulling effect and increases the damage multiplier of [Solar Eclipse]. It also increases the Trigger Probability of ranged weapons, synergizing with her passive skill effects. The ultimate consumes a large amount of Sanity, so moderately stacking Skill Efficiency is highly beneficial.

Passive - Interwoven Cries: After [Solar Eclipse] or [Lunar Hunt] is generated, there is a chance to additionally generate [Solar Eclipse] or [Lunar Hunt] for supplemental damage. The additionally generated [Solar Eclipse] and [Lunar Hunt] do not benefit from the ultimate's range increase and damage boost; they only have the standard skill range and damage. However, these additionally generated skills can still trigger further generations.

➢Key Intron Level Breakdown:

• I1: Increases the Trigger Probability of "Interwoven Cries", providing more opportunities for extra skill generation.

• I2: When "Lunar Hunt" hits a target, it increases the subsequent "Solar Eclipse" damage against that target, and vice versa, enhancing combo damage.

• I4: Increases healing received and Sanity recovery, improving survivability and skill rotation fluidity.

• I6 (Core Transformation): This Intron Level transforms Lady Nifle from a skill-based damage dealer into a versatile hybrid character capable of both skill and weapon damage, drastically increasing her damage frequency and output.

 

Character Demon Wedge Configuration (Most Critical!!)

Demon Wedges are the core of building Lady Nifle's strength, aimed at maximizing her Skill Damage and ATK.

Recommended Configuration:

Core

Feathered Serpent's Rescue

Slot 1	Slot 3	Slot 4	Slot 2
Typhon's Prime Morale	Griffin's Skylume Wildfire	Covenanter's Scorch	Covenanter's Scorch
Slot 5	Slot 7	Slot 8	Slot 6
Pan's Volition	Covenanter's Scorch	/	Covenanter's Scorch
Tolerance: 95 / 97

This setup leverages multiple Scorch wedges for massive Lumino ATK. Skylume·Wildfire is a perfect fit as it covers three essential stats she needs. The effect of Prime·Uplift (increasing damage dealt by you and your teammates) can be provided by a support character in your team.

Similarly, Prime·Serenity (which restores Sanity) is also best equipped on a support teammate. This allows your main DPS to focus entirely on damage-oriented wedges.

The empty slot (Slot 8) offers flexibility. If you find yourself running out of Sanity too quickly, equipping Wings·Inspo is highly recommended for the substantial boost to max Sanity and Skill Efficiency. If sustainability is not an issue, you can consider another offensive wedge.

 

Melee Weapon Selection Guide

Melee weapons primarily serve as stat-stick "off-hands"; Lady Nifle almost never uses them for attacking.

➢Withershade:

Weapon	Max ATK	CRIT DMG
	213.39	215%

Its skill provides a massive 72% Skill Range bonus. Since Lady Nifle's ultimate converts excess Skill Range into Skill Damage, this weapon equates to a direct, huge boost to Skill Damage.

➢Remanent Reminiscence:

Weapon	Max ATK	CRIT DMG
	213.39	210%

This weapon restores Sanity upon landing critical hits, effectively alleviating Sanity pressure for characters who frequently use skills. It also possesses an ultra-wide attack range, allowing it to hit more enemies simultaneously. Specific effect: ATK Range +2.0. When landing a CRIT with this weapon, there is a 66.0% chance to restore 3.0 Sanity. This effect can trigger once every 0.5s.

➢Wanewraith:

Weapon	Max ATK	CRIT DMG
	238.49	200%

This polearm significantly increases Skill Damage. Its charged attack mode allows the character to cast skills or use ranged weapons while dealing melee weapon damage. This type of Skill Damage buff is widely applicable and can benefit characters with various combat styles, directly providing up to 48% Skill Damage bonus.

 

Ranged Weapon Selection Guide

Ranged weapons are Lady Nifle's primary means of dealing damage (especially after I6), with choices revolving around the key stat Trigger Probability.

➢Embla Inflorescence:

Weapon	Max ATK	CRIT DMG
	188.28	220%

This weapon significantly increases the Skill Damage of Lumino characters and greatly enhances Skill Range, effectively improving the area coverage for characters reliant on skills for damage or utility. Specific effect: Skill Range +60.0%. While charging, the weapon gradually locks onto nearby enemies. Upon release, it fires tracking arrows at all locked targets. When a Lumino character deals Skill Damage, it grants +70.0% Skill DMG for 6.0s. The drawback is that you cannot simply hold the right mouse button to fire continuously; it requires charging. It is also not easily obtainable in the early game.

➢Entropic Singularity:

Weapon	Max ATK	CRIT DMG
	200.84	210%

This weapon greatly enhances Trigger Probability and continuously deals AoE damage based on this probability, synergizing extremely well with an Intron Level 6 Lady Nifle. Specific effect: Trigger Probability +150.0%. Each shot with this weapon has a chance (based on its Weapon Trigger Probability) to fire an extra projectile at no Ammo cost, dealing AoE Damage equal to 100.0% of its ATK.

➢Silverwhite Edict:

Weapon	Max ATK	CRIT DMG
	238.49	235%

This minigun can be obtained directly through a 4-choice-1 selection in the Starter Gift Box. It significantly increases ATK Speed, and its rate of fire stacks layer by layer with sustained firing. While it provides stable ranged firepower output, it offers relatively limited benefit to the character's overall combat kit. Specific effect: ATK Speed +50.0%. Furthermore, when an attack triggers a bonus effect, it grants an additional +10.0% ATK Speed for 12 seconds (up to 10 stacks). This effect is removed when switching weapons.

How to Obtain Character Thoughts

Unlocking and ascending Lady Nifle requires collecting her Thoughts.

The primary method is through the Secret Letter system. You can exchange 10 Secret Letter Clues for Lady Nifle's Secret Letter in the Shop. After completing a Covert Commission stage, you can open the Secret Letter for a chance to obtain her Thoughts. Please note that opening a Secret Letter is not guaranteed to drop Thoughts, and it typically requires obtaining 30 Thoughts to unlock the character.

Additionally, Thoughts for specific characters can be directly purchased for 150 Phoxene Plumules—the game's premium currency—via the Shop in the pause menu.

For efficient farming, focus on Covert Commissions under the "Character" category. These repeatable missions are the main source for obtaining character Thoughts. While the drop rate for a valuable reward like 10 Thoughts at once is around 10%, consistent farming will allow you to gather the required fragments over time. Furthermore, endgame activities like the weekly Nocturnal Echoes boss challenges and the Immersive Theater mode also provide opportunities to earn specific character Secret Letters or a large number of Secret Letter Clues.

 

Weapon Demon Wedge Configuration

This section primarily focuses on the configuration for the ranged weapon "Silverwhite Edict".

Slot 1	Slot 3	Slot 4	Slot 2
Lilith's Trammel	Lilith's Rain of Quivers	Lilith's Celerity Cunning	Fafnir's Carefree
Slot 5	Slot 7	Slot 8	Slot 6
/	Lilith's Rage Trammel	Lilith's Foldover	Fafnir's Hunt
Tolerance: 74 / 80

➢Core Goal: Stack Trigger Probability, Multi-shot, and ATK Speed.

➢Recommended Demon Wedges:

• Lilith's Trammel: Provides a large amount of Trigger Probability.

• Lilith's Rage Trammel: Provides a large amount of Trigger Probability. (But cannot benefit from the CRIT DMG stat).

• Lilith's Rain of Quivers: Provides Multi-shot.

• Lilith's Celerity Cunning: Increases ATK Speed. The ATK reduction is negligible since the weapon doesn't scale with ATK.

• Lilith's Foldover: Provides Multi-shot.

• Fafnir's Hunt: Provides Multi-shot.

• Fafnir's Carefree: To prevent running out of bullets; after equipping, bullets are basically unlimited.

 

Partner Selection / Demon Wedge Configuration

➢Best Team Composition:

DPS	Support	Support	Geniemon
Lady Nifle	Truffle and Filbert	Phoxhunter	Luminelf
			Ballbee
			Lumi

Truffle and Filbert: Can provide a damage boost of up to 61%, and also offers healing, making them a top-tier damage-increasing support.

Geniemon: Luminelf (Best in Slot) or Ballbee, Lumi (for transition).

 

➢Partner Demon Wedge Configuration Points:

Practical Application

Lady Nifle's operation cycle is intuitive and extremely explosive. In the routine state, control the field and output damage by alternately using "Lunar Hunt" (slow) and "Solar Eclipse" (ATK down).

When the ultimate skill "Misty Sea Requiem" is activated, she enters the "Funeral Rite" state. The next 6 skill casts do not consume Sanity, "Lunar Hunt" gains a crowd-pulling effect, and "Solar Eclipse" damage is significantly increased.

At this point, you can rapidly cast skills in succession, dealing devastating area damage. After reaching I6, using ranged weapon attacks also has a chance to automatically trigger "Lunar Hunt" or "Solar Eclipse", taking her damage output to the next level.

The following are brief strategies for several Level 60 Weekly Bosses using the Silverwhite Edict (basically, just hold down the right mouse button and keep shooting, while dodging their ultimate attacks):

Weekly Boss Lv. 60 Sibylle: Use "Solar Eclipse's" ATK reduction effect to counter her high-damage skills. Burst output during "Misty Sea Requiem", and pay attention to positioning to avoid ground area attacks.

Weekly Boss Lv. 60 Crystalophile: The slow from "Lunar Hunt" can effectively restrict its movement. Seize the moment after its attack recovery to activate your ultimate for burst damage.

Weekly Boss Lv. 60 Eclosioner: When it summons minions or prepares to charge, use "Misty Sea Requiem" enhanced "Lunar Hunt" to group enemies and quickly clear them.

Weekly Boss Lv. 60 The Warden of the Inferno: Use the dual skill slow and ATK down effects to reduce its threat. Pour out all skills during the shield break phase.

Weekly Boss Lv. 60 Beast From the Snowfield: Maintain distance, use I6 effects and skills for sustained damage output. Use "Misty Sea Requiem" to counter during its enraged state.

 

Conclusion

In summary, Lady Nifle is a late-game powerhouse who transforms at Intron Level 6. With the right build, she converts massive skill range into devastating damage and unleashes free skills during her ultimate, becoming a versatile hybrid carry who easily crushes all challenging content.
