Stygian Onslaught - Genshin Impact - Version 5.7
*Stygian Onslaught* is a permanent endgame combat event introduced in **Genshin Impact Version 5.7**, running from **June 25, 2025, to July 29, 2025**. It challenges players’ tactical skills and team compositions, offering rewards like Primogems, Dust of Enlightenment, and limited-time weapon skins. Below is a comprehensive guide based on available information.
Overview
**Event Type**: Permanent combat challenge, refreshed every 6 weeks.
**Location**: Liyue, south of Sal Terrae, north of Mingyun Village.
**Unlock Requirements**:
Complete Archon Quest Prologue: Act III "Song of the Dragon and Freedom."
Reach Adventure Rank 20 or above.
Recommended: Complete Interlude Chapter Act 2 "Perilous Trail" for the full experience.
**Duration**: Each cycle lasts 5 weeks, starting 8 days after a version update. The current cycle ends with Version 5.8.
**Gameplay**: Players face three consecutive boss battles across three battlefields, each requiring unique team compositions at higher difficulties. There are six difficulty levels: Normal (I), Advancing (II), Hard (III), Menacing (IV), Fearless (V), and Dire (VI).
Mechanics
**Battle Structure**:
Each difficulty involves three time-limited battles against different bosses.
From Menacing (IV) and above, players must use three distinct teams with no overlapping characters.
Ley Line Disturbances (combat modifiers) increase in complexity at higher difficulties.
**Bosses in Version 5.7**:
1. **Hydro Tulpa (Battlefield 1)**:
**Weakness**: Pyro; immune to Hydro.
Spawns Half-Tulpas periodically, which must be destroyed (preferably with Cryo or Freeze reactions) to prevent the boss from healing or gaining ATK buffs.
At Fearless (V) and above, it creates a shield that must be broken to avoid instant character death.
**Recommended Teams**: Pyro DPS (e.g., Mavuika, Xilonen), Cryo support (e.g., Citlali), and healers/buffers (e.g., Bennett). Hyperbloom or Bloom teams also work.
2. **Lava Dragon Statue (Battlefield 2)**:
**Weakness**: Pyro, Dendro; avoid Cryo/Hydro as they revert the boss to a high-RES form.
Has two forms: high-RES (default) and low-RES (after Pyro DMG). Continuous Pyro DMG immobilizes it and reduces RES.
**Recommended Teams**: Pyro-focused teams (e.g., Chevreuse Overload) or Dendro-based teams.
3. **Secret Source Automaton: Overseer Device (Battlefield 3)**:
**Weakness**: Cryo; Nightsoul’s Blessing triggers Forced Counterstrike for reduced RES.
Cryo DMG reduces Flow Momentum, stopping attacks and lowering RES. At Fearless (V) and above, Cryo is less effective, and the boss deals more DMG during Counterstrike.
**Recommended Teams**: Cryo DPS (e.g., Skirk, Shenhe), Hydro for Freeze (e.g., Furina), and crowd control (e.g., Escoffier).
**Exalted Ones**:
Up to 16 characters gain buffs (20% Max HP, ATK, DEF) based on server-wide usage in Dire (VI) clears.
Updated daily at 4:00 AM (server time). Buffs apply only to owned characters.
**Co-Op Mode**:
Available for all difficulties, but Fearless (V) and Dire (VI) rewards require single-player clears.
Normal (I) to Hard (III) support matchmaking; Menacing (IV) and above require inviting players in your world.
Co-Op adjusts enemy combat power based on the number of players.
Rewards
**Primogems**: 150 per difficulty for Normal (I) to Hard (III), totaling 450 Primogems.
**Dust of Enlightenment**:
A new item for redistributing Minor Affix upgrades on fully leveled 5-star Artifacts.
Obtained by:
Clearing Menacing (IV) and Fearless (V).
Solo-clearing Fearless (V) for full Dust rewards.
Reaching 1,200 Dire Prestige during Disturbance Outbreak.
**Dire Prestige**:
Earned by spending Resin (Original, Condensed, Fragile, or Transient) during the 10-day Disturbance Outbreak (June 25–July 5, 2025).
20/40/60 Dire Prestige per Resin type, respectively. Fragile/Transient Resin triples rewards.
At 120 Dire Prestige, gain a random 5-star Artifact from the chosen Domain.
At 1,200 Dire Prestige, earn a Dire Commendation (additional Dust of Enlightenment).
**Weapon Skins (Radiant Phantasm)**:
**4-Star Skin**: Clear Dire (VI) in single-player mode.
**5-Star Skin**: Clear Dire (VI) within 180 seconds total across all three battles.
Skins are cosmetic, element-themed, and expire at the end of the cycle due to Ley Line instability.
**Other Rewards**: Mora, Hero’s Wit, and Companionship EXP (doubled in Co-Op with 2+ players).
Tips and Strategies
**Team Building**:
Prioritize Pyro and Cryo for Hydro Tulpa, Pyro/Dendro for Lava Dragon, and Cryo/Nightsoul for Automaton.
Use Exalted Ones for stat buffs on difficulties I–V.
For Dire (VI), build three highly optimized teams, as it’s designed for high-investment players (often whales with C6R5 units).
