Gold is important for gamers. I think that this feature is not just in runescape, but also exists in other online role-playing games. It is a great achievement for some players to see that amount of gold on their coin pile.
Kill chickens and collect their feathers. This is a great one for those players out there that just have an account with combat level below 30, and it can help get combat experience as well. Once you talk to the banker for getting some gold and trade with the man in the east corner, you can buy laws for 210-299 gold each. In addition, to do this well you need to keep up to date with market prices. Last, you can go to the Rock Crabs in Relica and kill Rock Crabs no matter you runescape account is a member or not. And you can sell them to north of the East Falador Bank for more money if you are member. Your character will see a shack with two webs, cut both of them, then inside pull lever. It is a great profit for this action with your rs account.
Why not buying runescape accounts with a large number of gold?
