Wuthering Waves Version 3.7 Adds New Resonators and Map Zones
Wuthering Waves Version 3.7 introduces two 5-star Resonators, the Simulacrum Nexus of Mengzhou region, and quality-of-life updates including Echo stack storage and quest replay modes.
Wuthering Waves Version 3.7 arrives with new playable characters, regional expansions, and system optimizations. The update adds two 5-star Electro units alongside dedicated weapons, a new area to explore, and structural updates to inventory and UI features.
New Resonators and Weapons
Players can recruit two new 5-star Electro Resonators through featured convenes: Hsin, an Electro Rectifier user, and Suoming, an Electro Sword user. Accompanying their release are two matching 5-star weapons, the Blooming Jadehaven Rectifier and the Unspoken Rue Sword, available through the featured weapon convene.
Simulacrum Nexus of Mengzhou
A new region opens with Main Quest Chapter IV Act IV, titled Simulacrum of the Heart. The Simulacrum Nexus of Mengzhou includes sub-areas such as the Heartscape Labyrinth, Heart of Flames, Heart of Frost, Heart of Bloom, Heart of Stillness, and Heart of Ruin. The update introduces new enemies including Formrender, Soulfrayer, Skywatch Lancer, Bloomburst Puppet, and Jade Nether Serpent, plus a new Cost 4 Echo. Three new 5-piece Sonata Effects join the game alongside corresponding Tacet Fields and a Tacet Discord Nest.
System Optimizations and Quality of Life
Version 3.7 introduces Echo Stack storage support and a Replay Mode that lets players replay main quests from Versions 1.1, 1.2, and 1.3. Lineups now feature a 3D display mode, the in-game camera receives usability improvements, and the Echo Recommendation feature displays suggestions tailored to different Resonance Modes. A limited test adds tiered client resource downloads, allowing players to select specific graphics quality tiers.
Events and Rewards
The Moonlit Path event launches in Version 3.7, offering Moonlit Rings to unlock accessories like Hsin - Where Dreams Shine Clear and Rover - Not Even Close, plus a sigil, avatar, motorbike accessory, and a collection item for the utility wheel. The Leisure Event Cubie Wars rewards players with the Showtime sigil and Wooly's Blessing avatar. Additional rewards include motorcycle liveries, chat customizations, and phantom echoes.
