Like seriously I just saw this F2P guy he has like 2 phat sets and he's chatting to people in full corrupt dragon AND he just gave a phat set to someone and dropped 100mill, seriously how do people get that rich???
However it is someones goods, and the question remainds "how do People make so much GP?" Zerk Perk summed it up nicely: buy it online. Either that, or bot frost dragons/own a dicing clan.
