Top Echoes to Prioritize During the Echo Summon Event in Wuthering Waves
This guide is based on the Echo Summon web event, and what is available there. The best main Echoes to have on Resonators (your characters) are their best in slot Cost 4 Echo found in their character pages. This means that the web event Echoes doesn’t matter too much and is just a means to get a slight head start to the game and may be replaced later on.
It is always best to get the Gold 5-star (important) rank Cost 3 Echoes as they give the most EXP in data banks, and Echoes can be farmed by simply killing mobs and bosses in the overworld. Cost 3 Echoes always have ATK and ATK% substats.
Each Cost 1 and 3 Echo can have multiple possible Sonata set effects that can be acquired, and the best in slot main Echoes should be within the set the Resonator prefers.
If you don’t get the Echo that you want, at least pick a Cost 3 Gold rank echo just to further your data bank. Rarities are as follows:
5-star
4-star
3-star
2-star
