Stygian Onslaught Luna 6 Best Characters and Boss Advice
Stygian Onslaught is the hardest endgame content available in Genshin Impact facing against 3 different bosses with harder mechanics. Stygian Onslaught proves to be a challenge for all types of players. Here you can see an overview of the boss mechanics, some general combat advice as well as our recommended team compositions to clear Stygian Onslaught in version Luna 6.
But first, some general gameplay advice.
Co-Op Is Your Friend!
Stygian Onslaught can be cleared in Co-Op to an extent with some limitations. Difficulty 1/2/3 support matchmaking-based Co-Op allowing you to farm artifacts easily at Hard III difficulty while still being able to build up Dire Prestige.
Difficulties above that however require you to Co-Op with people inside your world. Furthermore, Fearless V and Dire VI's rewards are solo only. But you can therefore still gain the Dust of Enlightenment from Menacing IV.
Make Sure to Use Exalted Ones
2 Hours after each phases reset, Exalted Ones become available. These are the 16 characters based on the entire server's completion of Dire VI and grants a buff to your characters too. Providing increases to ATK, DEF and HP if you own that character. Exalted Ones do not give you access to that character!
Exalted ones can change daily too so if a character you own is not currently listed, they may change tomorrow.

Click below to see each of the 3 available bosses in the current patch Luna 6 Stygian Onslaught phase as well as weaknesses, and the best team compositions to clear easily.
Tenebrous Papilla
- Recommended: High-frequency Elemental DMG | Nightsoul-aligned DMG
Enemy Details
Tenebrous Mimesis
It can warp itself and transform into a formidable foe to attack.
Attrition Assault
Some attacks will inflict the stackable "Attrition" state, which will cause your own active party member to lose HP after a certain amount of time passes.
Beseech the Dark
During battle, the Tenebrous Papilla will initiate Beseech the Dark: Gives itself a Void Ward, enters a charging state, and prepares to unleash a Dark Bombardment. When Dark Bombardment is unleashed, it will deal DMG over an immense AoE. If you perform a certain number of Elemental attacks during this time, you can break the Ward, throwing the Tenebrous Papilla into disarray and preventing the Dark Bombardment from being unleashed. Nightsoul-aligned Elemental attacks are more effective at breaking the Ward. After breaking the Ward, the Tenebrous Papilla's All RES will be decreased for a period of time.

Beseech the Dark
When the battle begins, the Tenebrous Papilla will immediately initiate Beseech the Dark: Gives itself a Void Ward, enters a charging state, and prepares to unleash a Dark Bombardment. When Dark Bombardment is unleashed, it will deal DMG over an immense AoE. If you perform a certain number of Elemental attacks during this time, you can break the Ward, throwing the Tenebrous Papilla into disarray and preventing the Dark Bombardment from being unleashed. Nightsoul-aligned Elemental attacks are more effective at breaking the Ward. The Tenebrous Papilla begins the battle with increased RES. After breaking the Ward, the Tenebrous Papilla's All RES will be decreased for a period of time.

Attrition Assault
Some attacks will inflict the stackable "Attrition" state, which will cause your own active party member to lose HP after a certain amount of time passes.
Shadow Void Aegis
Affected by the Ley Line disturbance, the Tenebrous Papilla will deploy a Void Ward while initiating attacks. Perform a certain number of Elemental attacks to break the Ward. Once the Void Ward is broken, the Tenebrous Papilla will receive a single instance of immense DMG based on the DMG absorbed by the Ward and enter a weakened state for an extended period of time. Nightsoul-aligned Elemental attacks are more effective at breaking the Ward and will increase the DMG dealt when the Ward is broken. After being in the weakened state for a while, the Tenebrous Papilla will attempt to re-deploy its Void Ward.
Hatefully Beseech the Dark
Affected by the Ley Line disturbance, if the Void Ward remains unbroken for too long, the Tenebrous Papilla will initiate Hatefully Beseech the Dark: Enters a charging state, which, if the Void Ward continues to remain unbroken, will conclude with the Tenebrous Papilla unleashing a Wrathful Dark Bombardment, immediately defeating your current active character.
Combat Advice
- Nightsoul is key to breaking the Papilla's ward easily while also dealing increased damage.
- The Ward absorbs damage while active and then deals that damage back to the Papilla.
- This ward is also much beefier, requiring more hits to break compared to their normal version. This also means that teams which are often good against this boss, are a lot less effective.
Recommended Team Compositions
This is not a comprehensive list of teams. The inclusion or exclusion of any specific team that matches the advantageous elements does not necessarily reflect their strength in the meta.

|---|---|---|---|
| Chasca | Mavuika | Citlali | Xilonen |
| Kinich | Pyro Traveler | Emilie | Iansan |
| Mavuika | Iansan | Citlali | Xilonen |
| Varesa | Pyro Traveler | Chevreuse | Iansan |
Frostnight Herra
- Recommended:High-frequency Elemental DMG | Multi Elemental DMG | Lunar Reaction DMG
Enemy Details
Gloomveiled
Will enter a Gloomveiled state while in combat: All RES is greatly increased. After taking a certain number of DMG instances, it will exit the Gloomveiled state and change its Elemental Type to the element whose DMG it received the most during the time it was Gloomveiled, thereby gaining the corresponding Elemental DMG Immunity and Elemental Effects.
Purest Moonglow
Lunar Reaction DMG is more effective when breaking the Gloomveiled state. If it has taken more Lunar Reaction DMG when it exits the Gloomveiled state, its Elemental Type will change to Elementless, and it will not gain any Elemental DMG Immunity or Elemental Effects.
Combat Advice
- Will become permanently immune to the element it took the most hits from so careful rotation planning is important to ensure the right element hits the shield most.
- Takes 50 instances of damage to break out of the Gloomveiled state, however, Lunar Reaction DMG counts as multiple instances of damage.
- The boss takes on the element it becomes immune to, allowing for reactions to still take place.

Radiant Moongecko
- Recommended: Characters | Healing Characters
Enemy Details
Radiant Cocoon
After battle begins, the Nemesis harnesses Geo to apply Radiant Cocoon to characters and increase its own Geo RES. Characters afflicted by Radiant Cocoon deal less DMG and receive less healing. When a character's HP is restored to full through healing, they break free from the cocoon and gain the Disentangled effect, which boosts their abilities for a short time. Once any character in the party successfully breaks free, the Nemesis loses the Geo RES granted by Radiant Cocoon.
Voidstep Reverberation
During battle, the Nemesis leaves a Moonstone Anchor in its place before leaping to higher ground to prepare for Voidstep Reverberation. Some time later, it unleashes a large and powerful AoE strike. Use methods suited to dealing with Geo to break through the multiple Geo ward layers on the Moonstone Anchor. Destroying the Moonstone Anchor interrupts the skill's charge-up and deals massive DMG to the Nemesis. The more DMG the Moonstone Anchor takes during the preparation phase, the greater the DMG dealt to the Nemesis when the Moonstone Anchor is destroyed.

Vagrant Reverberation
After the battle begins, the Nemesis leaves a Moonstone Anchor in its place before leaping to higher ground to prepare for Vagrant Reverberation. Some time later, it unleashes a large and powerful AoE strike. Use methods suited to dealing with Geo to break through the multiple Geo ward layers on the Moonstone Anchor. Destroying it interrupts the skill's charge-up and deals massive DMG to the Nemesis. The more DMG the Moonstone Anchor takes during the preparation phase, the greater the DMG dealt to the Nemesis when the Moonstone Anchor is destroyed. Due to the effects of the Ley Line disturbance, using Geo attacks against the Moonstone Anchor further increases the DMG dealt to the Nemesis.
Unshakable Rock
Due to the effects of the Ley Line disturbance, the Moonstone Anchor's multi-layered Geo Ward becomes more resilient.
Radiant Cocoon
During battle, the Nemesis harnesses Geo to apply Radiant Cocoon to characters and increase its own Geo RES. Characters afflicted by Radiant Cocoon deal less DMG and receive less healing. When a character's HP is restored to full through healing, they break free from the cocoon and gain the Disentangled effect, which boosts their abilities for a short time. Once any character in the party successfully breaks free, the Nemesis loses the Geo RES granted by Radiant Cocoon.
Combat Advice
- Healer is absolutely required to clear the Radiant Cocoon debuff while also gaining a buff and causing the enemy to lose their Geo RES.
- Gecko creates a multi-layered Geo shield. It can be destroyed without Geo, but using Geo is the main way to break the shield as the damage the Gecko will take from the shield being destroyed is significantly larger (70% of Geo DMG vs 10% of anything else).
- After shield is broken, there is a brief stun window to deal damage before healing phase begins.
- If your strongest teams are unsuitable, it can be worthwhile to swap out one party member for a geo/claymore character.
