Summary
Echo
Perk 1
Bubble shield: Echo’s sticky bombs can no longer be fired out in a volley of explosive projectiles; instead, Echo will now create a large, floating, destroyable bubble shield with a set amount of HP.
By shooting through said bubble shield with Echo’s Tri-shot, the Tri-shot will be converted into sticky bombs. However, this in turn reduces the bubble shield’s HP, making Echo more vulnerable.

Tractor beam: Echo’s “focusing beam” is now significantly longer and can now aggressively pull enemies toward her.

Perk 3
Copycat: Echo’s ultimate ability, “duplicate,” can no longer duplicate enemies; instead, Echo will now duplicate a clone of herself that mimics everything the original does. While in this duplicated state, both Echo and her clone will have twice the amount of HP, twice the amount of damage, and half her original cooldown durations.
