How Echo Lab grades your build
Choose a Resonator and Sonata set, then enter the main stat and substat rolls for each Echo. A complete loadout has five Echoes with a total cost of 12.
The report separates roll value, recommended stats, and loadout completeness so you can see which Echo is worth improving. Scores are estimates based on the information you enter.
What is a good Echo score in Wuthering Waves?
In Echo Lab, a build score of 80 or more is a strong build and 90 or more is close to the ceiling. Most working builds land between 65 and 80, and the report shows which Echo would raise the score the most.
What is substat roll value?
Roll value compares each substat roll with the highest roll that stat can get, so a top-tier Crit Rate roll counts for more than a low one. Echo Lab weights roll value by the stats your Resonator actually uses.
What Echo cost should a build use?
A full loadout is five Echoes with a total cost of 12, usually 4-3-3-1-1. Echo Lab warns about an incomplete or under-cost loadout, and an over-cost loadout is not graded.
