Windchimers are new collectibles added in the Wuthering Waves 1.1 update that only appear on Mt. Firmament.
How to Use Windchimer Wuthering Waves
They behave similarly to Resonation Caskets from the base game, together unlocking unique rewards for the region in addition to the usual items to help level up your characters or draw new ones.
That may all be well and good, but the game is very bad at telling you where to take them. We want to rectify that now.
You can turn in your Windchimers in Wuthering Waves at the Repaired Strings, Preserved Melodies shop just west of Hongzheu by the tower.
