Stygian OnslaughtSpecial Domain
Location
Description
In this mode, the player must fight three powerful enemies, either aNormal Boss orLocal Legend equivalent in three separate battlefields. The player must also defeat the enemy within a specific amount of time.
There are six difficulties that the player can access:
| Difficulty | Enemy Level |
|---|---|
| Normal Challenge | |
| Normal | 40 |
| Advancing | 70 |
| Hard | 90 |
| Menacing | 100 |
| Fearless | 105 |
| Perilous Challenge | |
| Dire | 110 |
Players have 10 minutes to clear each individual boss on Hard and lower, reduced to 2 minutes at Menacing and higher.
Upon attempting Menacing or higher difficulties, the player will not be able to select a single character to be deployed multiple times. If the stage was already cleared and the player attempts to swap a character that participated in that stage into another, the game will warn the player beforehand, and confirming the selection after the warning will cause the previous record to be wiped. One-time rewards can still be claimed provided that the difficulty was already cleared first.
At Fearless and higher difficulties, the warped Ley Lines will add or enhance enemy mechanics, making them harder to defeat. These variants are typically unseen outside of Events. When attempting the level on Fearless or higher, either an existing mechanic is modified or a new one is added which significantly increases the boss' difficulty.
At all difficulties except Dire, a few characters are offered asExalted Ones, which increases their HP, ATK and DEF by 20%. Up to sixteen characters can be given the status of Exalted One, and several are provided at the start of each season. This bonus stacks alongside that from theImaginarium Theater.
When a stage is attempted, the player is temporarily locked in a small box. Their characters will additionally have noEnergy or equivalent.
The player can attempt the challenge inCo-Op Mode with other players. Hard and lower can be Co-Op'ed through normal matchmaking, while Menacing and higher requires the player(s) to be invited by the host into their world before doing so, and players will be unable to obtain rewards from Fearless or Dire in Co-Op, as they must be completed solo.
Although Stygian Onslaught is fought in adomain and may contain bosses, they do not count towards the respectiveBattle Pass tasks regarding bosses and domain counts.
When completing the challenge, no menus can be opened. When in the rewards claiming and preparation stage, only theCharacter Menu andInventory > Artifacts can be accessed.
After completing Dire difficulty alone, the parties used in the stages will be granted "Eminence." If attempting Dire challenges with the party, they will obtain "Enduring Eminence" instead, though they do not stack and will replace each other out depending on which comes first. When a character has obtained enough Eminence, they will become an Exalted One, granting them the HP, ATK and DEF buffs for lower difficulties. These are checked every day on reset.
As with the Imaginarium Theater and Spiral Abyss, the higher stages of Styigan Onslaught require well-built and synergized teams. This is especially true on Fearless and Dire, as the boss will gain a unique mechanic in their fight which can be harder to deal with if not using an optimal team. The shortened time and lack of Energy and equivalents additionally require players to how to make proper attack rotations, characters to have theirTalents and weapons highly or fully leveled and possibly multipleConstellations unlocked. For players who seek the minimum rewards, being able to clear Hard difficulty is more than sufficient for the primogems.
Rewards[]
Disturbance Outbreak[]
For the first ten days of the Stygian Onslaught, it will be in aDisturbance Outbreak state in which players can obtainartifacts similar to completing aDomain of Blessing if a stage is completed on Hard or higher difficulty. They may select the artifacts that they wish to acquire by selecting the "Rewards Settings" option. Players can useOriginal Resin,Condensed Resin,Fragile Resin orTransient Resin to claim rewards. In order to claim rewards in this manner, the player must have anAdventure Rank of 45 or higher. Additionally, players must have visited the corresponding domain at least once before it can be selected as a reward option.
During the outbreak, players gain Dire Prestige when claiming rewards from the outbreak. 20 is given for Original Resin and 60 for Condensed, Transient or Fragile Resin. When the player has obtained 120 Dire Prestige, an additional artifact will be rewarded. There is no limit to Dire Prestige. Players who have the resin are highly recommended to farm artifacts through disturbance outbreaks, as with ideal teams, players can complete the stage and reset it much faster compared to their original source, especially when it comes to those released beforeVersion 2.0. Once the player has obtained 1200 Dire Prestige, a one-time reward ofDust of Enlightenment is given.
Challenge Rewards[]
These can be claimed at any point during the Onslaught's duration.
The Radiant Phantasm are not permanent rewards, instead only available until next iteration of Stygian Onslaught is released. These are purely cosmetic rewards which override the appearance of a character's wielded weapon.

Gameplay Notes[]
- At Menacing and higher difficulties,[only verified for Menacing] when the player enters any battlefield that is currently displayed in their records, the character attributes (characters' levels and Constellation Levels as well as theTraveler's current element) that are displayed there will update as follows:
- All characters' attributes will update to what they were when the player enters Stygian Onslaught.
- This applies even if the player then exits or fails the attempted fight.
- This applies even if the player makes no changes to any of their teams.
- Upgrades made after entering the Stygian Onslaught domain are not included in this particular update to characters' attributes.
- If the player then successfully clears the battlefield such that it results in a better clear, then the characters who were used in that particular battlefield will have their attributes fully updated, including any upgrades that were made after the player entered Stygian Onslaught.
- As a result, characters' levels and Constellation Levels as well as theTraveler's current element as displayed in players' records may not match what they actually were when each battlefield was cleared.
- All characters' attributes will update to what they were when the player enters Stygian Onslaught.

Players withAdventure Rank 45 and above can consumeOriginal Resin to revitalize such Ley Line Blossoms and claim the corresponding rewards. Additionally, they can receive double the rewards by consumingCondensed Resin to revitalize Ley Line Blossoms. ConsumingFragile Resin orTransient Resin will allow players to receive triple the rewards.
Dire Prestige

It seems far from certain that the Ley Line Disturbance won't one day re-emerge...
