Stem worm is easy to kill, for example, so if you make a class that can kill mobs (my LK could do that, for example) then you can go kill stem worms until you get it. It'll be a long grind (maybe a few days, several hours each day to kill a few thousand stem worms), but well worth it for you if you get one. They sell for like 5m.
Truthfully, as a newbie you probably aren't going to have IC for a long time (I've been playing for over 6 months now and am not even close to IC gear yet) but the money will certainly help you get a leg up in this game, over most people who don't know enough about the economy to try something like that. But you have to have lots of patience. (I was lucky. I killed stem worms to get the items for a friend to make a headgear, and after about 100 of them I got the card. I was also stupid, though, since I put the card in a Manteau which mage classes can't wear >.< I think I ended up selling it for 2m or something)
But yeah, you may need to make another class or several other classes to support your levelling and moneymaking because at this point, you probably won't be able to buy IC gears (unless you donate or something).
