Infinite money:
If you are short on mesos and have some time to spare you could try this trick.First, you create a new character. Roll the dice so that its STR is high. Start training but don't buy equipment. As job advancement take warrior and continue training until you reach lvl 15. By now you will have gathered a lot of money. Store it with Mr. Wang, or one of his brothers, it doesn't matter which one. Now, switch back to your original character and collect the money from Mr. Wang.
NOTE: You have to make the character on the same server or the trick won't work
