Fairly obvious. When grinding, Perfect World Gold players get lots of money and item drops. Pick them ALL up, unless there's some insane swarm of monsters on top of it and you can't handle them. Do NOT ignore the money drops, even though there seems to be so little money. It builds up. A player lvling from 1-20 without picking up any money missed out on, on average, about 50-60K. And those are the easy no-grind lvls.Also, sell any drops you may get to the NPC. This includes Dragon Quest drops, unless you're actually able to sell them to other players. I wouldn't count on that. From my own experiences, it's best to sell every single DQ drop to the NPC, unless you're really desperate to upgrade your bank.
