The win condition
Use the merchant offer with clear expectations.
A rare result does not make every preceding purchase efficient. Compare total expenditure with the item you actually need.
| CHECK | WHAT TO KNOW |
|---|---|
| Preparation | An available Moss NPC and a fixed spending budget |
| Live timetable | MU WAR Events page and current in-game notice |
| After completion | Inspect the result and actual delivery window |

- 02
Read the cost and whether the result is random before purchasing.
- 03
Choose a spending limit, then compare each result with your actual gear needs.
- 04
Stop at the budget and decide whether a direct market purchase is a better upgrade route.
What makes the difference
Moss's official shop randomizes item types and options. Active costs and categories are those displayed by your NPC.
