I never ever had a sorc until recently when I decided to have a MF sorc for meph runs. I followed the meteorb guide in the stickies to the letter. So far I have completed the Disciple set, got an SOJ, shako. It is just amazing. Since at the beginning you will not have the super-equipment, you want to concentrate on meph NM runs. Believe me you'll get enough things toi trade and/or to use that you'll be able to do meph runs hell.
