The Myriad Snare – Rustfire Chassis is a world boss added to the Mengzhou region in Wuthering Waves. It is a heavy automaton that you also face during the version 3.5 main story, and it punishes sloppy positioning with long-reaching arm and chain attacks. The fastest way to beat it is to bring Havoc Bane damage, learn its wind-up tells, and dodge the moves that knock you down.
Quick answer: Travel to Western Fang Peak in Mengzhou, northwest of Xuanfang Hold, activate the Nexus, ride through the green holographic gate, and fight the boss with a Havoc Bane team such as Yangyang Xuanling, Phrolova, and Chisa. Dodge its glowing AoE and steam-charge, then spend 60 Waveplates to claim the drops.
Myriad Snare – Rustfire Chassis location in Mengzhou
The boss sits in the Western Fang Peak area of Mengzhou, to the northwest of Xuanfang Hold. You reach it through the Hundred-Span Corridor, and there is a Nexus nearby that lets you teleport straight to the spot.
Attacks to watch and how to react
The Rustfire Chassis fights with a heavy left arm, a chain-and-ball right arm, and a large shield wheel. Most of its damage comes from telegraphed slams and charges, so reading the wind-ups matters more than raw reaction speed.
| Attack | Tell | Response |
|---|---|---|
| Triple left-arm slam | Winds up before the third strike, which hits harder | Dodge the final slam; it deals increased damage |
| Ball and chain | Right arm stretches into the air, then slams down | Move clear or you get knocked back |
| Spinning shield wheel | Arm rotates with the large shield | Parry when timed correctly |
| Arm grab | Right arm extends toward you | Dodge to avoid the brief stun and damage |
| Steam charge | Raises the shield to its front and vents steam | Dodge sideways as it charges |
| Glowing AoE | Body starts glowing | Get distance; the blast can knock you out |
| Chained shield swing | Attaches shield to chains, swipes ground twice | Dodge the two swipes, then the slam |
Weakness and best teams
The Rustfire Chassis is weak to Havoc Bane and carries high Fusion resistance, so avoid leaning on Fusion damage dealers. This weakness also applies when you meet it in endgame modes such as Tower of Adversity and Endstate Matrix.
Chisa and Yangyang Xuanling are the standout picks because both can inflict Havoc Bane. Any of the following teams clears the fight efficiently.
- Yangyang Xuanling, Phrolova, Chisa
- Chisa, Cartethyia, Ciaccona
- Hiyuki, Lucilla, Chisa
Rewards for defeating the boss
You need 60 Waveplates to collect the full reward set after a win. Without them, you can still absorb the Echo but forfeit the experience, materials, and intimacy. The drops include the following.
- Intimacy
- Union EXP
- Sealed Tube
- Resonance Potion
- Energy Core
- Solidarity’s Loneflame
- Standard Weapon Mold
- Myriad Snare: Rustfire Chassis echo
Once the health bar empties, the fight ends and the reward prompt appears. Keep a Havoc Bane character on the field, punish the wind-up frames on its slams and charge, and this Mengzhou automaton becomes a reliable source of Solidarity’s Loneflame and its matching Echo.
