I’ve been exploring the misty peaks of Nimbus Sanctum in Wuthering Waves since it first appeared, and I can tell you that finding all nine Sonance Caskets is a love-hate relationship. The region is stunning—shiny clouds, golden rivers, and that eerie mist—but those caskets? Some are a breeze, others make you want to pull your hair out. But hey, Astrites are Astrites, right? As of 2026, these locations haven’t changed, so here’s my personal walkthrough.
Why Bother with Sonance Caskets?
Each casket you turn in gives you Astrites, the premium currency for pulls. Nine caskets might not sound like much, but every bit counts when you’re saving for the next banner. Plus, exploring Nimbus Sanctum is an adventure in itself—just watch out for Lorelei, the region’s iconic boss. 🐉
1. Mistveil Bay Pillar
Teleport to the Resonance Beacon south of Polyphemos Windmills and glide southeast into Mistveil Bay. You’ll see a pink tree—the casket is on a pillar near it. Easy enough, but don’t get distracted by the view.
2. Gondola Platform Roof
From the first casket, head right towards the gondola platform. Look under the roof—there’s Sonance Casket No. 2 hiding there. You know the drill: grab it and move on.
3. Broken Bridge near Resonance Nexus
Teleport to the Resonance Nexus in the area, turn around, and look up. The casket is on a broken bridge. You’ll need to run across the shore and take a short swim to the broken archways. Be careful—there are enemies along the way. I learned that the hard way. 😅
4. Thessaleo Falls Cliff
This one is south of Nimbus Sanctum, but it’s easier to teleport to the Resonance Nexus at Thessaleo Falls and head north. Climb the cliff in front of you, then fly off it. The casket is right beneath, between two pillars. It’s a bit of a leap of faith.
5. Garden of the Lost Golden River
Teleport to the Resonance Beacon inside the Garden of the Lost, turn around, and head outside the cave. Keep going left until you hit the mist-covered golden river. The casket is floating in the air to your right. Don’t be fooled—it might look like it’s near Averardo Vault, but it counts for Nimbus Sanctum.
6. Hidden Behind Rubble
Go back to the Nimbus Sanctum Resonance Nexus and head straight up the stairs. Go left, pass all the enemies (or fight them, your call), and look for a set of rocks stacked on each other. Take an immediate left, and the casket is behind some rubble. Sneaky little thing.
7. Wingray Ride
Teleport back to the Resonance Nexus, head up the stairs again, and grab a ride from the Wingray on your left. Let it carry you all the way up—you’ll spot the casket to your left. Sometimes you just need a taxi, you know?
8. Southeast Broken Building
From your current spot, fly southeast. Find the broken building—keep flying left until you reach a massive broken bridge. Right below it is the building with the casket inside. It’s a bit of a maze, but the view from above helps.
9. Above the Broken Bridge
The final casket is above you, on the opposite side of that massive broken bridge. Equip your flying gear and head up into the air. It’s at the very southeast of the Lorelei Boss Arena, on the bridge that divides the Atrium of Reflections from the Garden of the Lost. Congratulations, you’ve got them all!

Final Thoughts
Collecting all nine Sonance Caskets in Nimbus Sanctum is a rite of passage for any Wuthering Waves player. It’s not just about the Astrites—it’s about the journey, the views, and the satisfaction of checking them off your list. So grab your gear, watch out for Lorelei, and happy hunting. And if you get lost, well, at least the scenery is nice. 😉
