tell me how?

so on the trading section there are a few people who regularly sell gold
like they just magically get gold or something. I rarely see people farm.

how do they guys make gold?

running raids everyday for rare drops and farm for scrolls to sell it's really not that hard to make gold also selling Nx for gold.

Exactly what zartan said....and do the Weekly Raid bosses for rare drops such as tears,wings and stuff!

Scroll Farming.

many chars, and then run raids everyday on each character.

Colhen in flames 1 day=1milion gold NO ARMOR JUST SWORD! with a party=2 milion gold a day i think

I farmed Colhen in flames 5 days or something like that and i made 9 milion gold

colhen in flames lol

Raids, scrolls, weaponsmithing? S2 drop rates are terrible but once you get them, they are good money
