Guide to the Stygian Onslaught event in Genshin Impact

With the arrival of Genshin Impact version 5.7 , players received new permanent content to test their skills: the Stygian Onslaught event . Similar to the well-known Spiraling Abyss, this mode features challenging battles against powerful bosses, requiring three different teams , mastery of elements, and strategic character choices. The event is available from June 25, 2025, and will be updated with each new game version.

How to unlock and participate in Stygian Onslaught

To access the new event, you must complete the "Tumult Subduer" mission , available in the game's events tab. After this introduction, the player unlocks the Stygian Onslaught domain, located in Liyue. The goal is to defeat three bosses in sequence , each requiring a different team.

The event offers five difficulty levels : Normal, Advanced, Hard, Terrifying, and Fearless , with the higher difficulty levels only being unlocked as the previous ones are completed. A hidden difficulty, called Dire , can only be accessed after completing the event on Fearless mode .

Key bosses and elemental weaknesses of each stage

Each battle in Stygian Onslaught requires prior knowledge of enemy weaknesses in order to assemble effective teams . Below are the bosses from the current version and the ideal elements to face them:

1) Hydro Tulpa

This boss is immune to Hydro damage , so using Pyro characters . During fights on harder difficulty, the Tulpa creates shields and summons clones. The trick is to destroy these clones quickly and use strong attacks to break the protection before it activates devastating abilities.

2) Lava Dragon Statue

The statue has high resistance to Cryo and Hydro attacks, but is more vulnerable to Pyro and Dendro attacks . The higher the difficulty, the more instances of Pyro damage are needed to immobilize it. Using two Pyro characters speeds up the process of weakening the boss.

3) Secret Source Automaton: Overseer Device

This automaton is especially resilient, with high defense against all elements. Its weakness lies in Cryo , making it ideal to assemble a team with two or three characters of this type. On higher difficulties, the boss attempts to accumulate Flow Momentum , requiring constant attacks to interrupt its spinning ability.

Tips for facing challenges effectively

Besides choosing the right characters, some strategies are essential to winning across the three battlefields, especially on the harder difficulty levels:

• Utilize teams with elemental synergy and well-defined roles (DPS, support, healer).
• Take advantage of elemental mastery buffs and knowledge of boss immunities and resistances
• Save resources like original resin to farm artifacts at the end of battles.
• Pay attention to vulnerable moments to use decisive attacks with greater impact.

What are the rewards from Stygian Onslaught?

The event is highly rewarding , especially for players seeking Primogems and Ascension resources . Check out what you can obtain:

By completing the event on Dire , you can obtain 4 and 5-star weapon skins , as well as rare materials to upgrade equipment.

Is Stygian Onslaught worth playing?

Stygian Onslaught establishes itself as one of Genshin Impact's most comprehensive high-level activities, focusing on strategic character use, elemental synergy, and combat mastery . It's an opportunity to test all the knowledge acquired throughout the game while earning a significant amount of rewards .

Furthermore, since it's permanent content, players can complete the challenges at their own pace, without the time pressure of temporary events. The expectation is that with each new update , the bosses and rewards will be renewed, maintaining a challenging and rewarding experience.
