In Wuthering Waves, Sonance Caskets: Ragunna are valuable items found in Rinascita, containing fragmented memories of the past. These can be easily collected using the Grapple Utility.
Players can trade these caskets with the Tweensy Weensy merchant in the Garden of the Lost for rewards such as Astrite, Casket Sonnar Use Permits (Rinascita), Resonance Potions, Energy Cores, Plushie Village Restoration Logs, and Shell Credits.
