Aion Gold

This is the bread and butter to becoming rich. It's crucial that you learn how to buy and resell to become rich. The key to buying and reselling is learning the market value of certain items. I can't tell you exactly what to look out for, since the economy per server is different but I can tell you certain things to look out for. In the forest beyond Altgard, you will find both campaign stuff and general quests. It will send you back in here several times, sometimes for more than one quest, so be ready to visit the Mumus a lot. Now that your group has stumbled their way past the jumps (or cleared it with ease if you have half a brain and breathe through your nose rather than your mouth), there's only about 20 minutes of trash until you get to the last boss, which is a giant Manduri. This is also one of the first fights with a ridiculous gimmick that must be adhered to in order to succeed.

Golden Eye Mantutu will frequently become either hungry or thirsty during the duration of the fight, you'll be able to tell from the debuff. Buying and Reselling isn't exactly a walk in the park, don't expect to step in the auction house doors, buy a few items and sell them 5 minutes later. Also don't expect to sell all of your items, you will make mistakes and sometimes have to sell the item for less then what you purchased it for. The good news is that you will learn quickly from these mistakes and be able to turn around and profit off of them. Something to always keep in mind as well is, if you where dumb enough to buy an item for 100g that was only worth 50g, is someone else out there will be as dumb as you and buy it for 100g. You just have to find that person.
