Is your character level 130? Do you have +9 items? Congratulations! You can enjoy the joy of refining your equipment to +10-+12.
Bring your +9 item and certain amount of Dragon Balls to the Ethereal in the market (320,228). The NPC there will refine your equipment in his Wuxing Oven. Then, you will get +10 equipment. Currently, he can refine your equipment to +12. (Details)
This function will be implemented soon. If you desire to refine your equipment to +10 to +12, get ready for it.
