The first part of this video includes an important tip on how to upgrade echoes so you save on materials, and the second part lists ALL the possible substats you can roll along with their estimated probabilities. I hope the information helps and don't feel bad if you don't have perfect echoes yet or even any pieces with crit, I barely have any myself and I've been farming every day. Let me know in the comments if you have any questions!
