After purchasing the Mileage Supply Crate, players will receive a predefined quantity of Mileage Code Decoder (varies by region) each time upon logging in game daily, for a certain number of days.
- Each day logging in counts as one attendance. The player can only receive the Decoders once per day.
- The crate's duration cannot be stacked. Once the crate expires, there's a cooldown period of 15 ~ 30 days (depends on each kind of item).
Alternatively, the crate has been bundled in the form of a booster pack which comprises a crate supplying 5 decoders for 10 days, a weapon duration of 100 days and an additional 500% EXP and points for 10 days.
