🗺️ How to Farm
Drops from Aero Tacet Discords. Cost 4 echoes have higher rates from boss-level enemies. Use Interactive Map → for spawn locations.
Feed unwanted lv.0 echoes to level promising ones to lv.5-10. If substats are bad, feed that echo to the next one — exp transfers efficiently.
Use Tuners to reveal substats. Stop farming when you have CRIT Rate + CRIT DMG on Cost 4, and at least one CRIT stat on Cost 3/1 pieces. Read Echo Guide →
