Genshin 6.2 Luna III Stygian Onslaught Guide | D6 To Get Weapon Skins!

Hello Travelers! The latest Stygian Onslaught “Luna III” is live as of December 10, 2025, and this round is surprisingly friendly. The lineup focuses on simple elemental counters and shield breaking, so many teams can handle it with ease. If you haven’t jumped in yet, take a look at the recommended setups and tips for a smooth full clear.

In this guide, we’ll cover boss mechanics, elemental reactions, and the most effective team strategies to help you overcome every stage of the Stygian Onslaught and claim all the rewards with ease!

 

Basic Rules

This game mode is already live in the current update and features six difficulty levels. Each run requires defeating three consecutive bosses, and starting from Difficulty Level IV, you’ll need to form three non-overlapping teams to take on the challenge.

Teams & Time Limit：

• Levels 1~3 Each Boss 10min. You can use a character more than once, and you can Co-Op by Matching.
• Levels 4~5 Each Boss 120s. You cannot use a character more than once.
• Level 6 Each Boss 120s. If total time is below 180s, you get a better reward.

Dust of Enlightenment is a new item that will be added to the game onceGenshin lmpact 5.7 goes live. This item can be used to re-roll artifactsubstats so that you can turn a mediocre artifact into a good one. You can also choose which substats you want to prioritize before re-rolling.

Artifact Rewards：You can choose an Artifact Domain and claim rewards from it via the following methods:

• After completing Level 3 or above, use Resin to claim reward once.
• Every phase there is a 10 day Burst Period, when you can spend an extra 20/40/60 Resin to claim 1/2/3 rewards.

For every 120 Resin spent via the 2nd method, you obtain 1 extra 5-star artifact, and after spending 1200 Resin, you will get an Artifact Reroll material.

Difficult Summary

For those seeking Primogems, clearing the D3 is straightforward, as enemies cap at Level 90 with no enhanced mechanics. Fractured D4 increases the challenge but allows Co-Op mode; if you cannot clear it solo, you can call for backup from experienced players to secure victory. Since the rewards include Dust of Enlightenment, it's worth pursuing. Fractured D5 offers the same rewards as Level IV but is solo-only, pitting you against Level 105 bosses with enhanced mechanics. However, if you aim to obtain the Weapon Skins, prepare for a significant challenge!

Simply put:

D3: Open world level difficulty and coop; timer 10 min, able to get all gems

D4: 11-1 abyss difficulty

D5: 12-3 abyss difficulty or slight higher

D6: even whales would struggle

D6 Rewards: Weapon Skins

Clearing the challenge rewards a full set of limited-time Weapon Skins, applicable to all weapon types and all elemental visual effects. Players can individually enable/disable these skins per character. Completing the stage within 180 seconds upgrades the skins to 5-Star quality, granting them enhanced visual effects.

*Note: These skins purely alter appearance and provide no stat bonuses or gameplay advantages, functioning similarly to Character Outfits.

For example. Observe how the recolored "The Unforged" greatsword perfectly complements Marvuika's aesthetic! This harmonious pairing is truly visually stunning

Recommend Comps

Let's be honest: D6 poses a significant challenge. It requires three fully independent teams (no shared characters) capable of defeating bosses each possessing over ten million HP. This demands considerable investment, placing it firmly within reach of dedicated players with well-developed rosters. Below are our recommended team compositions and key Constellations to help you claim the radiant Weapon Skins!

Floor 1	Floor 2	Floor 3
Iniquitous Baptist: Resonant Wrath	Battle-Hardened Iktomisaurus: Frostbound Resolve	Experimental Field Generator: Extreme Potential

For Chamber 1

Enemy Mechanics:

The Iniquitous Baptist rotates through Electro, Pyro, and Hydro shields with values of 12U, 18U, and 18U, which sit at about 150% of their overworld strength. Each shield break removes HP equal to 50% of the absorbed damage, capped at 12.5% of its max HP, and clearing all three shields triggers an 18 second paralysis window. Throughout the fight, it shifts its attacks to match the active element and maintains a simple 10% resistance to all elements without any special immunities.

Combat Mechanics:

Breaking a ward with elemental reactions deals significant damage based on how much the ward absorbed, so teams with fast and steady elemental application perform best. After each shield break you get about a three second window to unload damage and reset your rotation before the boss shifts to the next element. 

Hydro＋Dendro and Hydro＋Cryo are the most efficient options, both noticeably better than Hydro＋Pyro, so prioritize those pairings when possible. The shield values are manageable, letting high application teams push the boss into frequent shield breaks and constant transitions. 

Once all three shields are destroyed, the boss enters an eighteen second paralysis window, which is your main chance to run full burst rotations, refill energy, and maximize damage.

Recommended Team Compositions:

D6 Recommended Teams
Skirk Ayaka	Escoffier	Furina	Yelan Charlotte
Nefer	Lauma	Xingqiu Nilou	Nahida Baizhu
Neuvillette	Furina	Escoffier	Citlali
D1-D5
Chasca	Citlali	Furina	Bennett
Lauma	Nahida	Kuki Shinobu	Xingqiu

For Chamber 2

Enemy Mechanics:

The Battle Hardened Iktomisaurus opens with 70% all resistance and 110% Cryo resistance, then jumps into the air to form a 24U Cryo Shield while instantly charging all party Bursts. Cryo Gadgets appear and each one destroyed removes 9.6U, while Decoy Vortexes can be pulled into the boss to cut 35% Anemo resistance and remove 2U, up to three stacks. Breaking the shield deals 10% max HP plus 50% of the absorbed damage, capped at 35% max HP, and knocks the boss down with extra fall damage. If you fail to break it, Frosthail Zones spawn for reaction based chip damage, and a roaming Disruption Vortex applies AoE Cryo and further weakens the shield if it hits the boss.

Combat Mechanics:

The boss hovers often, even outside shield cycles, so ranged options or pull effects make the fight smoother. The Cryo Shield appears almost immediately and then again roughly 50s later, letting most runs see two shield phases in a 120s chamber.

Breaking a shield fully refills everyone’s Burst and creates the main DPS window thanks to the fall damage. The shield itself is not demanding since 24U can be cleared by any steady Pyro application, even something as simple as Amber’s charged shots and Burst.

Resistances stay high throughout the fight, so bringing your own resistance reduction is important if you want clean damage. Even after being knocked down, the boss tends to take off again, so ranged pressure or crowd control keeps it from wasting time in the air.

Recommended Team Compositions:

D6 Recommended Teams
Venti	Durin	Bennett	Faruzan
Chasca	Durin	Bennett	Citlali
D1-D5
Klee Lyney	Durin	Chevreuse	Fischl
Mavuika Arlecchino	Xilonen	Citlali	Jean

For Chamber 3

Enemy Mechanics:

The Experimental Field Generator constantly creates a Gravity Reduction Field, letting all characters jump much higher than normal. While active, it unleashes undodgeable gravitational shockwaves that gain one enhancement stack every 5s, growing stronger and more frequent. Each Plunging Attack removes a stack to control the shockwaves. Reaching a certain height triggers a Ley Line effect granting ATK +600% for 1.5s. The boss’s Ousia core is resilient, and even three Pneuma hits cannot fully disable the Gravity Reduction Field, keeping high-jump mechanics active throughout the fight.

Combat Mechanics:

Characters affected by Bond of Life take 2.5× damage from certain attacks of the boss. In addition, affected characters continuously lose HP based on a percentage of Bond of Life plus a fixed amount. When off-field, this bleed does not cause death, leaving roughly 5% HP; on-field, it can lead to lethal damage. This bleed persists until the Bond of Life is removed.

Healing alone can remove the Bond of Life, but the required healing is very high and difficult to achieve. It’s often more reliable to use character-specific mechanics to clear it — for example, Arlecchino or Clorinda, who can interact with or utilize Bond of Life effectively. Shields can mitigate some of the negative effects, reducing HP loss significantly, though affected characters will still steadily lose health. Managing Bond of Life properly is key to surviving this boss.

Recommended Team Compositions:

Conclusion

This cycle of Stygian Onslaught in Version 6.2 has just refreshed, but instead of being the toughest yet, it actually shifts back to simple elemental countering. The lineup is quite forgiving, with shield breaking as the main focus and little demand on team mechanics, making this phase much easier to clear than expected.

Securing the luminous special-edition weapon skins requires well-invested C6 DPS characters, while supports need only their essential Constellations unlocked. With this preparation, clearing the challenge becomes achievable!
