How to use Sonance Casket in Wuthering Waves

In Wuthering Waves’ overworld, you’ll occasionally spot resources known as Sonance Caskets. Picking up your first casket initiates the Remnants of the Past Days quest, introducing the Casket Delivery system and unlocking another way to get valuable items.

Where to turn in Sonance Casket in Wuthering Waves

Once you pick up your first Sonance Casket and start the Remnants of the Past Days quest, you’ll need to head to Jinzhou and speak to the local relic merchant, Chenpi. You’ll visit this city during the main storyline, but if you’ve ventured past it, you can fast-travel to the Resonance Nexus and visit the quest marker.

After speaking to Chenpi, you’ll give him the Sonance Casket, where he’ll explain the item is and its purpose. Doing this introduces the Casket Delivery service, which, in exchange for Sonance Caskets, you’ll receive items such as Astrite, Lustrous Tide, and EXP potions, among other valuables. Each delivery level requires more Sonance Caskets, so you’ll need to keep an eye out for these items during your travels before giving them to Chenpi and receiving each reward tier.
