Using Dragonballs to level up

Use Dragonballs to level up in Market!
You may or may have not come across a man dressed in white near the Market entrance. His name is the "Unknown Man" and he's know for being a master at training and emptying the sake reserves.

He knows how to level up with Dragonballs
At first, this man will try to take some silver off you, 100 silver to be exact. Give it to him and he'll be more than happy to train you for one small request. A bottle of wine of course, more especifically, Drunk Celestial.

Where do I get the Drunk Celestial?
All you have to do is make your way to Twin City and find ShopBoy. He stands next to ArtisanOu and the guy who helps you level up and socket your items in Twin City. Ask him about Drunk Celestial and he will give you some for a small price. Once that is done, you'll have your bottle of Drunk Celestial. So now you must make haste back to the old drunk UnknownMan, for he is going to teach you how to level up with Dragonballs. And so once you give him his daily dose of Drunk Celestial, he will require 1 or 2 Dragonballs to level you up. The number of Dragonballs depends on the level, however rest assured that 2 Dragonballs are for the higher levels. It's important that you know that the UnknownMan can only do this for you once a day.
