It's no use. If you change the lv, the only thing that will change is the note about what lv are you. Not your status, not your skills, nothing but the text. For example: If you're using a lv 1 char, change the lv into 150, and try to wear a lv-2 armor to him, it won't succeed. The same goes for skills and status. You won't have any spare skill points, nor status points. So you will be written as a 150 char with the power of lv 1 char. No point in doing that but for scamming ppl to trade accs.
