How Echo Erase Works
Play each day’s stage
A new stage opens daily, so the full reward set needs you to come back across the window.
Easy, then Hard
Clearing Easy unlocks Hard for that stage.
Hit the stage goals
Rewards come from each stage’s goals, not just from clearing it.
Requirements
- Reach Union Level 14.
Tips
- Stages unlock daily but stay open, so a missed day can be made up — just not after November 9.
