Wuthering Waves Game Guide

Modulation I

Drag Echo A from your hand onto Echo B in the Deployment Zone to perform a Modulation.

Modulation II

Echo A will replace Echo B in the Deployment Zone upon Modulation, inheriting Echo B's DMG (the inherited DMG will add to Echo A's original DMG). Echo B will be shuffled back into the deck after Modulation and may be drawn again in later rounds.

Modulation III

Modulation activates an Echo's Modulation effects. The full effects are dependent on the specific Skills. Only on-hand Echoes can be Modulated. You cannot Modulate a Deployed Echo with another Ehco in the Deployment Zone. Stacking two Echoes that are both in the Deployment Zone will only result in them swapping positions.

Modulation IV

A Deployed Echo can only be Modulated twice. To Modulate a Cost 3 Echo, it must be stacked on top of a Modulated Echo. In other words, you must Modulate a Cost 1 Echo first before you can Modulate a Cost 3 Echo.
