Introduction to Impermanence Heron Echo Guide
Wuthering Waves Impermanence Heron Echo Guide: The Impermanence Heron is a powerful Overlord-class Echo in Wuthering Waves, occupying a Cost 4 slot. Upon use, it transforms the Resonator into the Heron, dealing massive Havoc DMG in a wide area. This makes it ideal for burst damage and crowd control. It pairs well with Havoc-based Sonata Effects, enhancing its damage potential. The Echo is obtained by defeating the Heron boss in the Sea of Flames. Best used with Resonators who benefit from high burst windows or Echo transformation abilities.
Impermanence Heron Overview
The Impermanence Heron is a Cost 4 Overlord-class Echo in Wuthering Waves, part of the Moonlit Clouds Sonata set. Its Echo Ability transforms the user into the Heron, delivering an initial aerial strike that deals Havoc DMG and grants 10 Resonance Energy. Holding the ability extends the transformation, allowing the user to spit continuous flames, each dealing 25 Havoc DMG. At higher ranks, damage scales up to 40.05% per hit. If an Outro Skill is used within 15 seconds after activation, the next character gains a 12% damage boost for 15 seconds. The skill has a cooldown of 25 seconds, reduced to 20 at higher rarities, and must be equipped in the first Echo slot to be used.
