Frostnight Herra Strategy
The Frostnight Herra demands the use of Lunar Reaction or Multi-Element teams to prevent it from gaining Elemental Resistance during its charging state. As such, full Lunar-Bloom or Lunar-Charge teams work the best.
Lunar teams are preferred since dealing Lunar DMG during the Herra's charging state will not make it immune to any element. Otherwise, Dual DPS teams that can benefit each other Off-Field are also able to complement each other well against this boss.
Battle-Hardened Lightkeeper Strategy
The Battle-Hardened Lightkeeper functions the same as the Nod-Krai Sigurd Local Legend, and teams with access to the Ascendant Gleam Moonsign are highly incentivized.
With that in mind, Lunar-Bloom or Lunar-Charge are able to pierce through its Wild Hunt healthbar easily, as Ascendant Gleam lets you deal direct DMG to its gray health bar. Otherwise, any team with good grouping and Elemental DMG can whittle down its HP.
Veteran Frost Operative Strategy
The Veteran Frost Operative is unique in the sense that it requires characters that can either cleanse Bond of Life, or requires Shielders that can ignore the Bond of Life affliction mechanic altogether.
Any team with high damage output can quickly burn through the Frost Operative's health and Shield bars.

How to Play Stygian Onslaught
Go to the Event Domain in Liyue
The event domain for Stygian Onslaught is located north of Mingyun Village, right beside a Teleport Waypoint. Interact with the ley line disturbance to enter the Stygian Onslaught challenge menu!
Complete 3 Time-Limited Battles
During the challenge, you must go to three separate Battlefields and fight time-limited battles. When all opponents in the three battlefields have been defeated, the challenge is considered complete for this difficulty level.
The higher the Difficulty, the stronger the enemies become. Each Difficulty also has mechanics that will make the battle more difficult for players.
Select From Six Difficulties
| Difficulty | Level Conditions |
|---|---|
| 1 - Normal | Unlocked from the start Rewards from Solo/Co-Op Random Match Co-Op Available |
| 2 - Advancing | Unlocked from the start Rewards from Solo/Co-Op Random Match Co-Op Available |
| 3 - Hard | Unlocked from the start Rewards from Solo/Co-Op Random Match Co-Op Available |
| 4 - Menacing | Complete Hard Difficulty Rewards from Solo/Co-Op Invite Co-Op Only No Repeat Characters in each Battlefield |
| 5 - Fearless | Complete Menacing Difficulty Rewards from Solo only Invite Co-Op Only No Repeat Characters in each Battlefield |
| 6 - Dire | Complete Fearless Difficulty Rewards from Solo only No Co-Op Available No Repeat Characters in each Battlefield |
Stygian Onslaught has up to 6 Difficulty Levels available. However, Difficulty Level 4 and above requires completing the challenge on the Difficulty Level below it.
You can still complete Fearless difficulty in Co-Op mode, but you cannot collect rewards for it.
Dire Difficulty Level 6 Rewards Only in Single Player
Dire Difficulty Level 6 also requires players to complete Difficulty Level 5 in Single Player Mode. Similarly, the rewards for Difficulty 6 can only be claimed by doing it in Single Player.
Differences on Dire Difficulty's Perilous Challenge
On Stygian Onslaught's Dire final difficulty, there are special objectives in play, as well as even more limiting conditions that make it into a true challenge for even the most seasoned players.
Perilous Objective: Complete Within 180s
In order to earn the Sublimation weapon skins, Dire has the added objective of requiring you to complete the entire Stygian Onslaught challenge within 180s.
This means you must complete each battlefield at an average of 60 seconds in order to clear this objective.
A Powerful Opponent
The enemies present in Stygian Onslaught's Dire difficulty have significantly more health and deal far more damage than even their Fearless counterparts, requiring players to be able to output tremendous damage in order to clear it.
Exalted Ones Boon Inactive
As this is the Dire difficulty challenge, any buffs that the Exalted Ones receive are not in play during Dire difficulty, meaning you must make do with the whole challenge solely relying on the strength of your own characters.
Challenge in Co-Op
If you are having a hard time completing the challenge alone, you can also invite teammates and clear the stages in Co-Op to acquire most of the rewards together!
Note that you cannot collect rewards for clearing Level 5 and Level 6 Difficulty in Co-Op.
Give Buffs to Characters as Exalted Ones
When characters are used by other players to clear Dire Difficulty Level 6, they become Exalted Ones. In Difficulty Level 5 and below, Exalted Ones gain Eminent Boon and receives additional buffs when added to the party.
Exalted Ones Refresh Every Day
There can be a total of 16 Exalted Ones at any point in the challenge. Exalted ones are revealed two hours after the Stygian Onslaught event starts, and will refresh every day at 04:00 AM (Server Time) for the duration of the event.
Choose Artifact Rewards
Players can choose the Artifact Sets they wish to receive as a reward for completing the Stygian Onslaught challenges through the Reward Settings!
Obtain Artifact Rewards During Disturbance Outbreak
For the first 10 days of the event, Travelers can obtain extra artifact rewards by using any kind of Resin after clearing any stage at Difficulty Level 3 or higher.
This is known as the Disturbance Outbreak state and will always refresh whenever Stygian Onslaught resets.
