Zhongli’s leaked new Envisaged Echo in has just undergone a massive change in the beta tests that can nearly be compared to a buff.
Echoes are a cosmetic trait that was added to the game recently, shortly after the debut of the Imaginarium Theater game mode.
In fact, these Echoes can only be obtained by participating in special trials within the activity. Echoes are commonly referred to as character trails in due to the visual effect they cause on whichever character they are unlocked for.
Envisaged Echoes leave a trail behind the characters as they move around. So far, only a few characters have access to these Echoes, and these trails all contain visual effects that are somewhat related to the character’s abilities, backstories, or elements.
Diluc, for example, leaves behind a trail of flames as he runs around. Now, it seems like two characters will get Echoes in Version 5.1.
