Wuthering Waves Simulacrum of the Heart is Chapter IV Act IV of the Mengzhou main story and the quest that opens the Simulacrum Nexus for normal Version 3.7 progression. It becomes available after Chapter IV Segue: The Nethermancer’s Requiem, then sends Rover into the Manifold Sanctum with Suoming while the city is dealing with rumours that Xuanfang Hold is doomed to fall.
The main reason Wuthering Waves Simulacrum of the Heart matters outside the story is how much content sits behind it. Progressing Act IV opens the seven Heart Realms, the Inner Threshold exploration systems, the new weekly Suhsin fight, permanent Blooms for the Shadow progression and the Tales Quest Moonlike Heart, Mortal Longing after Act IV is complete.
How to start Wuthering Waves Simulacrum of the Heart
- Complete Chapter IV Segue: The Nethermancer’s Requiem.
- Open the Main Quest section and select Chapter IV Act IV.
- Follow the objective into the Manifold Sanctum and Simulacrum Nexus.
- Activate new Resonance Beacons as the story opens the Heart Realms.
- Finish the Act IV story if you want Moonlike Heart, Mortal Longing to appear.
If Wuthering Waves Simulacrum of the Heart is not appearing in the quest list, check the previous Chapter IV story first. Version 3.7 did not remove the earlier narrative prerequisite, and simply reaching the new patch date does not skip The Nethermancer’s Requiem. The quest is permanent, so there is no event deadline forcing you to rush it before November.
What Wuthering Waves Simulacrum of the Heart unlocks
| Content | What Act IV does |
|---|---|
| Simulacrum Nexus of Mengzhou | Takes Rover into the new Version 3.7 area. |
| Seven Heart Realms | Opens the Heartscape Labyrinth and six named Heart areas through story progression. |
| Inner Threshold | Introduces Reconstruction, Stasis, Proliferation and Composite Anomaly mechanics. |
| Suhsin the Inevitable | Story progression is required before the weekly boss becomes a normal farming target. |
| Blooms for the Shadow | Permanent Nexus Fox Shadow progression becomes available during the new story. |
| Moonlike Heart, Mortal Longing | Requires completion of Act IV before the Tales Quest unlocks. |
The most useful approach to Wuthering Waves Simulacrum of the Heart is to activate Beacons and complete nearby mandatory mechanics as you go, but leave full exploration cleanup until the story has stopped changing the accessible routes. Heartscape Labyrinth and the individual Heart Realms are more efficient to revisit once their transitions and realm abilities are properly available.
Simulacrum Nexus exploration during Wuthering Waves Simulacrum of the Heart
The new region is not one flat map. Heartscape Labyrinth connects Heart of Flames, Heart of Frost, Heart of Bloom, Heart of Stillness, Heart of Ruin and Heart of Appearance. The story introduces realm-specific abilities that alter objects and routes, so an obstacle that looks impossible early can simply be waiting for the next Key mechanic.
Use the dedicated Nexus pages for cleanup rather than turning Wuthering Waves Simulacrum of the Heart into one enormous checklist. The unlock article explains the map gate, the Inner Threshold guide covers anomalies, and the Realm Key pages separate Reconstruction, Stasis and Proliferation so the story page can stay focused on progression.
Does Wuthering Waves Simulacrum of the Heart unlock Hsin materials?
Indirectly, yes. Bloom of Hearkening is found around the new Nexus, and Suhsin the Inevitable is tied to the 3.7 story progression. Those are two of the new resources Hsin players need, while the new Echo and Sonata farms also sit around the same release content.
If Hsin is your priority, progressing Wuthering Waves Simulacrum of the Heart early removes several farming gates at once. You can then collect Bloom of Hearkening during exploration, start the weekly Remnant of the Wheel claims and move onto Heart of Sworn Vigil farming without waiting until the end of the patch.
Rewards and post-quest content in Wuthering Waves Simulacrum of the Heart
Act IV provides the normal one-time Main Quest rewards and unlocks the larger 3.7 exploration economy around it. More importantly, completing the story is the eligibility requirement for Moonlike Heart, Mortal Longing, a permanent Tales Quest that begins when a mysterious girl contacts Rover on WavesLine about scattered Feeling Capsule Shards.
Wuthering Waves Simulacrum of the Heart is therefore the central gate for the whole launch cluster. Finish the prerequisite Segue, follow Act IV until the new region systems are open, and complete the chapter before troubleshooting any later quest that explicitly requires it. Most missing 3.7 content problems begin with an account that has not actually finished this story step.
