Echo

The Pangu Terminal can capture and reproduce a unique frequency, known as the Tacet Discord ability. However, there is a possibility that it will leave behind a Reverberation effect when shattered. This Reverberation can be transformed into an Echo through the Pangu Terminal's Data Bank, providing a useful advantage in combat.

When a Tacet Discord is defeated, the remaining frequency may become an Echo. You can obtain Data Bank EXP by absorbing an Echo for the first time. Level up Data Bank to raise the probability of Echo drop. Echoes are an important source of a Resonator's strength. Resonators can use the Echo Skill of the Echo equipped at the top.

Echoes are remnants of Tacet Discords that Resonators can equip to gain additional stats and use echo specific skills called Echo Skills.

Echoes can be aquired by defeating Tacet Discords with drop rate depending on the player's current Data Bank level.

Echoes have 5 properties:

Rarity

Sonata

Cost

Echo Skill

Stats

Rarity ranges from 2 to 5 and its rate depends on the player's current Data Bank level.

Sonata determines the set effect the Echo contributes to. Each Echo has a fixed set of Sonatas it can be and is determined randomly on drop.

Each Echo has cost which determined by its Threat Level. The value starts from cost 1 for the Common threat level up to to cost 4 for the Overload and the Calamity threat levels.

Classification

Echoes can belong to one of four Classes: Common (Cost 1) , Elite (Cost 3), Overlord (Cost 4) and Calamity (Cost 4). Resonators are given an Echo Cost limit which depends on the player's current Data Bank Level. The total Cost from all the equipped Echoes on a character cannot exceed the player's Echo Cost Limit. The maximum achievable Echo Cost Limit is 12 which unlockes at Data Bank Level 9.

Echoes have different rarity. The rank of a captured Echo depends on the player's current Data Bank Level. Note that rarity and cost have no correlation. The maximum upgradable Level of an Echo depends on its rarity. This rule also applies to possible Tacet Field echo drops.

Comment
"Though echoes are mostly remnants after reverberations that can be scanned and applied later, the term Echo also reffers to already animated shells crafter and comonly used in rinascita as minions and sort of living automatons. So this termin is culturally non-specyfic and can either mean remnant echo or crafted one."
