Sonance Caskets are a type of collectible in Wuthering Waves that can be exchanged for various kinds of rewards. They also count towards 100% completion progress of a region, which provides additional rewards to the player. In the new Rinascita region, there are eight sub-regions, each with their own set of collectibles. In this guide, we will help you collect all the Sonance Caskets in the Nimbus Sanctum sub-region of Rinascita.
How To Collect Sonance Caskets In Nimbus Sanctum

The Sonance Caskets scattered across the Rinascita region must be grappled onto, instead of the traditional way of collecting by passing through them. This is why you will notice that most of the caskets in this region are located in hard-to-reach areas, such as on top of buildings or high up in the sky.
