How to maintain and repair your powerful Lucky Items.
1. What is the Jewel of Extension?
In MU Online, the Jewel of Extension is a specialized item uniquely designed to increase the durability of "Lucky" items (Lucky armor sets and weapons). Because Lucky Items cannot be repaired via normal merchants, this jewel is essential for maintaining your gear.
"Lucky gear is powerful but fleeting. Only the craftsmanship of David can extract the magical essence needed to restore them."
2. Crafting Process (Refine Lucky Item)
The Jewel of Extension does not drop from monsters; it must be crafted by sacrificing other Lucky Items.
Step 1: Locate NPC David
- Travel to the Elbeland map.
- Find and interact with the NPC named David.
Step 2: Refine Your Gear
- Choose the "Refine Lucky Item" option from his dialogue menu.
- Place a spare or unwanted Lucky Item into the combination window.
- Click the combination button to attempt crafting the Jewel of Extension.
Failure Warning:
This refinement process is not guaranteed. If the combination fails, the inserted Lucky Item may permanently disappear (depending on your specific server settings).
