• 1Rewards per difficulty cleared; Fearless and Dire pay out only after a single-player clear
• 2During the Outbreak: artifacts from a chosen Domain of Blessing for Resin, plus extra artifacts and Dust of Enlightenment from Dire Prestige

• Challenge gameplay: You must select a difficulty first. After you enter a challenge, you must complete 3 phases, for a total of 3 time-limited battles. The challenge is considered complete once all opponents in all 3 battles are beaten.
• Difficulty: difficulty levels in ascending order are "Normal," "Advancing," "Hard," "Menacing," "Fearless," and "Dire."
• The higher the initial difficulty selected, the more restrictive the rules applied during the challenge, and the tougher enemies will be.
• From the "Hard" difficulty onward, you can only unlock the next difficulty by clearing the current one.
• "Exalted Ones": There can be a maximum of 16 "Exalted Ones" at any one time during the challenge.
• "Exalted Ones" will obtain buff effects; adding them to your party will help you complete the challenge.
• There can be a maximum of 16 "Exalted Ones" at any one time during the challenge, and their number is subject to change.
• Under the "Dire" difficulty, "Exalted Ones" no longer obtain buff effects.
• Disturbance Outbreak: In the first 10 days from when the challenge is available, the Ley Line disturbance will be in an "Outbreak" state.
• During the Disturbance Outbreak, players with Adventure Rank 45 and above can challenge stages at "Hard" difficulty onwards, and upon completing them, can consume Resin to earn the rewards from their chosen Domains of Blessing, while also accumulating Dire Prestige.
• Accumulate a certain amount of Dire Prestige to receive extra Artifact rewards and Dust of Enlightenment.
• After the Disturbance Outbreak ends, players will not be able to consume Resins to claim rewards from their selected Domain of Blessing.
• Completing a more difficult challenge will also let you obtain the rewards from the difficulties below that one.
• Rewards for "Fearless" and "Dire" difficulties can only be claimed upon completing the single-player challenge.
• Co-Op Mode: All difficulty levels support Co-Op Mode of up to 4 players.
• "Normal," "Advancing," and "Hard" difficulties support matchmaking or Co-Op Mode within the same world.
• "Menacing," "Fearless," and "Dire" difficulties only support Co-Op challenges within the same world.

Quoted from HoYoverse’s notice on HoYoLAB.

1. 1The Outbreak ends on 10 October. After that, Resin can no longer be spent in the mode, so the artifact farming has to happen in the first ten days.
2. 2The tier list has a board for each boss of this rotation. A character T0 overall can sit three bands lower against one of them.
3. 3Exalted Ones carry buffs until Dire, where the buffs are switched off. A Dire clear is a test of the roster as it is.
4. 4Menacing and above only allow Co-Op within the same world, so matchmaking is not a way through the top three difficulties.
