Now that's clear, let me walk you through how to unlock Stygian Onslaught.
To unlock the mode, you need to reach Adventure Rank 20, complete the Archon Quest Prologue: Act III – Song of the Dragon and Freedom, and finish the World Quest Tumult Subduer. For the best experience, it's also worth tackling the Interlude Chapter: Act II – Perilous Trail before diving in.

To clear the challenge, you will need quick reflexes, strong teams, and just a bit of grit to take down your opponents before the clock runs out.
Stygian Onslaught Reset Details
Unlike one-off events, Stygian Onslaught runs on resets. So, you get fresh chances to play and earn rewards.
● Daily Reset: Every day at 4:00 AM server time.
● Weekly Reset: Some stages and higher-tier rewards reset weekly.
Daily resets let you farm resources consistently. If you skip too many, you will lose out on Primogems and progression.
Present Cycle Duration (September 17 – October 21, 2025)
The present round of Stygian Onslaught in Version 6.0 Luna I has kicked off on September 17, 2025, at 10:00 AM server time. When the stages rotate, all bosses reset as usual, but this time they come with a new twist called the Disturbance Outbreak State.
While this state is active, you can still clear battlefields and earn artifact rewards. Once it ends, artifacts will no longer drop, though you will still be able to keep playing Stygian Onslaught normally until the event finishes on October 21.
Strategies and Team Compositions
Let's talk strategies and best teams for Stygian Onslaught 6.0 because the right comp can make or break your run.
| Boss | Strategy | Best Tips |
 Aeonblight Drake | Increases its resistance if you only use one element. Use a multi-element team with up to two DPS characters. | Two elemental DPS units work well, or use Chasca as a solo DPS since she can draw on multiple elements. |
 Battle-Scarred Rock Crab | Functions like the Nod-Krai Crab Tsar Local Legend and are weak to Bloom-related reactions. | Bring Bloom, Hyperbloom, or Burgeon teams. Use Lunar-Bloom with Lauma for extra damage, and keep Bloom reactions active for heavy AoE damage. |
 Battle-Hardened Fireblade Shock Trooper | Similar to the Raskolnikov Local Legend from Nod-Krai, with a tough triple-layered Multi-Shield. | Use high-frequency and high-consistency damage. Electro-Charged is very effective, and Lunar-Charged with Ineffa helps break shields faster. |
Best Sample Composition For All Stages
The best teams for Stygian Onslaught Genshin Impact include:
| Stage 1 |  Citlali |  Xilonen |  Mavuika |  Chasca |
| Stage 2 |  Nilou |  Kokomi |  Nahida |  Lauma |
| Stage 3 |  Furina |  Ineffa |  Neuvillette |  Kazuha |
Stygian Onslaught: How It Works
Genshin Stygian Onslaught is a new domain challenge featuring three consecutive boss fights. Instead of floors and chambers like the Spiral Abyss, think of them as three equal stages. If you are going solo, you will need three teams (12 characters) ready to go, but you can also tackle it in multiplayer Co-Op with friends.
The event has five baseline difficulties. Tougher tiers unlock as you progress. It's built for replay value, so you can expect to run it multiple times for rewards.
Artifact Farming Made Better
Before starting, you will pick what artifact domain you want to count as Stygian Onslaught. Each boss drops a Leyline flower, which works like normal domains: spend 20 Original Resin, Condensed Resin, or the new Fragile Resin to claim your loot. It is important to note that Fragile Resin can work in standard domains and Leylines. It is not just limited to this event, which makes it a handy new farming tool.
Rewards & Dire Prestige Explained
Clearing the first three difficulties nets you 450 Primogems, but the real grind comes from Dire Prestige. Every 120 Resin you spend here turns into 120 Dire Prestige, which earns you an extra 5-star artifact. Thanks to this system (and Fragile Resin), some players might walk away with 7 gold artifacts in one session.
Dust of Enlightenment: Reshape Your Artifacts
In Dust of Enlightenment, a new item that lets you reshape a level 20 artifact by redistributing the rolls between two substats. While you can’t swap substats completely (no turning flat DEF into ATK%), you can smooth out the stats to get closer to a god-roll piece.
You can earn Dust by:
● Clearing higher difficulties.
● Reaching 1200 Dire Prestige.
● Picking it up in the paid Battle Pass.
● Receiving free copies (one-time bonus, gifted in Version 5.7).
Exalted Ones Buff
Exalted Ones is another twist. If your friends clear harder Onslaught fights using specific characters and you own those characters too, then your versions get a 20% all-stat buff. It's a cool incentive to grow your friends list and borrow some team inspiration.
Dire Difficulty: The Final Challenge
Now comes the question: what is Dire Difficulty Stygian Onslaught in Genshin Impact? After finishing the fifth difficulty, you will unlock Dire Difficulty. Enemies here come with new mechanics and much higher levels. It doesn't reward Primogems or similar rewards. Think of it as the ultimate test of your builds and teamwork.
Note: To truly master Stygian Onslaught, you will want to learn how to beat Dire Difficulty under 180 seconds. The trick is to focus on elemental synergy, consistent high DPS, and avoiding downtime during boss mechanics.
Conclusion
Stygian Onslaught Genshin Impact is a long-term challenge that blends strategy, skill, and steady rewards. The rotating cycles, layered difficulties, and team-based mechanics push you to experiment with different comps and sharpen your combat reflexes. Overall, it promises fast-paced battles with meaningful rewards and a whole lot of fun.
