Refinery Tower

🏗️ The Refinery Tower
The **Refinery Tower** is the only location in MU Online where players can transform raw Gemstones into powerful Jewel of Harmony. Access to this facility is a reward for the server's bravest warriors.

Operational Status

Event Dependency
The Refinery Tower is not always open. Its state depends entirely on the outcome of the **Kanturu Event**:

• Success: If players successfully defeat the Nightmare, the tower gates remain open for a full **23-24 hour period**.
• Failure: If the Nightmare is not defeated, the Tower remains sealed until the next event cycle.
• Open Access: Unlike the Maya event itself, once the tower is open, all players can enter freely without needing a Moonstone Pendant equipped.
