**Halo, welcome to Storeparty.**

(Each product = 1 echo)

Buyers can request sub-stats for echoes (minimum 3)
Example: Crit Rate/CDM/ATK% (2 of the requested sub-stats will be obtained.)

**Note:** Echo tuning will only guarantee 2 desired stats. With luck, you may get 3.

**Buyers only need to prepare:**
1. An account that has reached the Data Bank level:
- For **purple echoes**: Must reach Lv. 15

2. Buyers must **not log in** to the account during the boosting process.
3. Processing time: **1-7 days**, depending on echo drops, as farming is daily-limited.
