At level 18 you have many options open to you. You can try Mara KQs for some easy exp and money, if you can get in. Also you can train at Mara sailors and pirates. Or you can try Boogies, Boars, Keblings and such. Just go around and find a nice little spot to grind in that gives you a nice Exp to Hp regeneration ratio and grind till your wanted amount of Exp or when your out of stones. xD

ok dont know if any of this info will help, but here goes...I have a lvl 22 fighter and at the moment Ive been grinding around in the Forest of Mist (around near the Elderine gate), at the moment I can handle Keblings, Joker Keblings, Grave Robbers, Prock Zones, Little Lizardmen ect, they seem to be giving me good exp, and I can handle 3 sometimes 4 at any one time with the help of pots and maybe a scroll or two, tho I have to say, sometimes it can still be a little bit dangerous for me in there, only because they like to hang out in mobs, and Ive been attacked by 7 or 8 monsters at a time and that's when I don't stand a chance lol...but I have to warn you, I took a lvl 17 fighter there the other day with me and he lasted all of about 5 minutes lol..
But at your lvl you should be able to handle Smart Phino's, Mara pirates and Sailors, Mara Pirate Elites, Speedy Boogys, all found at the Sea Of Greed or the Sand Beach
Ive also been into Luminous stone 1, just for keblings etc, took out Kebling Speeder the other day, (quite proud of my self lol) tho its those darn Mage Books that get me everytime lol
anyhoo hope this helped a little!!! good luck
