Wuthering Waves Game Guide

Clearance Command: Echo Control

Use the Clearance Device to turn the hostile security Echoes in the vault into allies. In this state, they will prioritize the safety of the clearance holder above all else. If an allied Echo is too far from the Clearance Device or the Clearance Device is not equipped, it will revert to its hostile state. *Controllable Echoes are marked by a golden aura.

Clearance Restriction

The Clearance Device can only control a limited number of Echoes. Once this limit is reached, you won't be able to control any additional Echoes. Upgrade your Clearance Level to increase the number of Echoes you can control simultaneously. *Controllable Echoes are marked by a golden aura.
