Dear Sky Pro's,

With great sadness, we announce that the Sky MU PRO project will be closing down. On the 10/08/2020, the server will shut down permanently.

This closure is a result of the low player interest. It has been a great adventure for us, and we hope that you have enjoyed the fruits of our hard work.

Thank you for staying with us.

Best wishes,


Sky MU Update 09-07-2020

Dear Sky Pro's!

As you continue to play hard, we continue to work hard! We are glad to present to you an update which will bring a new level of excitement to the Sky MU experience!

As usual, we are open to your suggestions and feedback. If you have any cool ideas, or you feel that something isn't right - just let us know!

Update Summary:

Premium Antihack system deployed

Cash Shop Prices adjusted.

Grand Reset Requirement reduced to 100 resets 

Zen Lottery added to Miracle Moss Gambler - 500,000,000 zen per spin.
    - A few of the possible rewards:

    - Jewel Stacks - 10
    - Refining Stone Stacks - 10 
    - Dark Jewel Stacks - 3

Market Economy Liquidity Boost

Many players have expressed that the market is suffering because there is not enough W Coins in circulation. To address this we have:

- Reduced pricing in the xShop
- Reduced the grand reset requirement from 200 resets to 100 resets
- Updated certain bosses to give a chance to acquire WCoins.

Further to this, as a short-term measure, all players will be receiving a WCoin boost within the next 24 hours. Details as follows:

  • All players will be gifted with a 2500 WCoins to boost in-game market liquidity. This WCoin boost is not applied to multi-accounts. WCoins added to 1 account per player.
  • In addition to the 2500 WCoin boost, all donators will receive a 10% WCoin bonus on all donations made to date. This is intended as a complementary measure for your support, and also a soft reimbursement for the now lowered xShop pricing.
