Requirements:

 You should be a swordsman and your starting city must be ARGENT CITY.

Find somebody that could plvl you for free or a guy higher than you that you could pay for plvling (only when your lvl 8 you can party). Now ask him if he could plvl you to the bears Lv12 then when you make it to lvl 10 go to Newbie Guide Senna then talk to her and pick the option "Swordsman Promotion" then go to Swordsman Peter and talk to him about the Promotion.Now talk to him again and tell him about the Promotion and he will ask you if you could kill 12 piglets.After that quest he will let you go to General william then you will do another quest and after that quest you go back again to General william and you can become a swordsman now. Now that your lvl 10+ you can get skill points every lvl.To use them, Buy at the Grocery and pick up skills and also click your stats and there is a button that is like this >>>>>>+<<<<<<. Now click the + that is shown beside the word STR, Str is Strenght and lets you lvl up your str lvl it does the hit on you.But you can pick whatever you want if you want to but i suggest you only lvl up AGI and STR.AGI is the attack speed that you do when you attack.Some player pick becoming a pure AGI and after they are fast in AGI they pick STR.I suggest that if your gonna become a Pure AGI, Put some little more in str so that you could hit even 50+.Now that you've finished your quests at General William, He will give you a letter that you need to give to Guard Peter. Now your a Swordsman.All you need to do now is lvl up.first if your lvl 10-15l go train at lvl8 piglets.lvl15-20 go train at the Abandoned Silver mine with the Lv12 bears till lvl 20.now that your lvl 20 you need to continue lvling up at lvl12 bears or try find somebody that could plvl you at the smugglers till lvl 25.when your lvl 25 try to kill smugglers(at Rockery Haven)till lvl 30.Now that your lvl 30 go get a party mate that is about your lvl or higher or lvl 25+ that could help you lvl up at Andes Forest Haven with the lv30 Mad Boars till lvl 40 (note that i lvled  up using mad boars lvl 30 till lvl 40 i really tried to lvl up i worked hard and i bought Mini Amps that could double my Exp.)
