Just tell us what exactly you need to know and we'll be able to help you.
As for the equipment: just lvl with the beginner gear until lvl 40, then I would use a C grade weapon (if possible also c grade armor but only if you need it). With C grade you can lvl until 85. If you want to lvl a bit faster then get yourself a higher grade (that's not necessary though) or ask someone to lvl you (when you are lvl 73 someone else with lvl 85 can lvl you up). When you are full lvled try to get the best gear. You will need vorpal or elegia depending on your class.
It's been many years since I last played L2, and I can't really remember the basics of it like equipment guide to which level and etc...
I remembered a little but not enough to keep going.
Can anyone help me
