In the resource system of Silver and Crimson, the Echo Store is an extremely important part, especially in terms of character growth and enhancement. The rational use of resources from the Echo Store can significantly boost your overall combat power. Today, I will bring you a guide on exchanging items in the Silver and Crimson Echo Store. Unlike other stores, the exchange resources in the Echo Store mainly come from Echo Tokens accumulated through drawing cards in the permanent card pool, which makes the choice of exchange strategy particularly crucial to avoid wasting resources.

First, it's important to clarify that the currency for the Echo Store primarily comes from drawing cards in the permanent card pool, with one Soul Token obtained for every 200 draws. Since obtaining tokens is quite difficult, it's essential to budget carefully and ensure each token is used on the most valuable characters and resources. It's worth noting that the Echo Store can only be used to exchange for souls of characters already owned, and does not involve limited or ancestral faction characters, which simplifies the selection process to some extent.

So, how should the priority for exchanges in the Echo Store be planned? First, if there are core characters in your lineup that need level breakthroughs, prioritizing the exchange for their souls is the most direct and effective choice. Level breakthroughs not only increase a character's base attributes but also unlock more potential, helping you gain an advantage in later battles.

Secondly, for those higher-strength characters, such as Dorethea, Acalepha, and Cang Lin of Quest, enhancing these characters' constellation levels plays a significant role in overall combat power. Especially when facing high-difficulty content like the late-game main story and abyss, upgrading these characters can greatly enhance the lineup's output and survivability, so it's recommended to prioritize them for exchanges in the Echo Store.

Additionally, although the exchange range of the Echo Store is relatively fixed, there is still some flexibility in choosing characters and resources based on individual lineup needs. If certain specific characters' constellations have not reached full levels, or there are pressing breakthrough needs, it may also be appropriate to consider exchanging for their souls.
The above is the content of the Silver and Crimson Echo Store exchange guide. The use of resources from the Echo Store should be planned reasonably according to your current lineup needs. There's no need to blindly pursue constellation upgrades for all characters; instead, focus resources on key characters that can improve overall combat power. Through scientific resource allocation, you can build a much stronger lineup in the world of Silver and Crimson.
