In Wuthering Waves, the Key of Tremble, aka Key of Tremor, Key of Passion, and Key of Tranquility, are Metaphor items players can use in the Illusive Realm game mode to upgrade Echo abilities.

Each upgrade for an Echo in the Illusive Realm requires a certain amount of Elements. While almost every upgrade offers an Element value, the Keys in particular are used to raise the Element value quickly for fast Echo level-ups.

With that said, here are the three Metaphor Keys and their effects in Wuthering Waves:

  • Key of Tremble: 3x Electro (Purple)
  • Key of Passion: 3x Fusion (Red)
  • Key of Tranquility: 3x Glacio (Blue)

For instance, let’s say an Echo Upgrade requires ten Electro. If you get the Key of Tremble upgrade from Metaphor, it will contribute three Electro, leaving you with seven more Electro to collect in order to unlock the upgrade.

You can get the Key of Tremble, Key of Passion, and Key of Tranquility from Metaphor at the end of a wave inside the Illusive Realm. Granted, it appears to be one of the three upgrades. In addition, you can purchase the keys using Dream Fragments from the Ebony Gatekeeper before the final round.
