(if you don't see what im seeing right now don't worry we will get right in to that at the bottom)

Press Edit

now you should be seeing this


Here you can add or remove Sonata or Attributes that you want

Now you must be wondering why I told you how to edit cause here I have some suggestions to give for the Sonata Sets.

From Cost 3 (Glacio DMG) - Cost 3 (Havoc DMG)
I suggest adding these 2 Sonata sets

Its just for future proofing just incase.

(You can go to the next part im just showing how it should all look now.)






Here is how it all should look like.

This is the setup

Select all

Remove Rejuvenating Glow

Attributes

Pick Attribute as ATK%


Cause some characters are much better off with an ATK rather then a Double Elemental DMG Bonus.

e.g the new Dream of Lost set for Phrolova

The Setup

Pick Dream of Lost

Attributes just Select all


Cause you can still modify these with Modifiers

Press Backpack

Now you should be here

Press Select all

It should look like this now

Press Lock

Now your echoes should be locked
