I am just about to unfold the deepest secrets for good money in this game, and point out some of the most obvious things, to help you all make your keep here. Then I will give you a few hints...
Note - Time to time, there may be an update resulting in the method not being 100% accurate, or there may be a new method to making money. I will try to keep the guide as close to the truth as possible at all times. Now, lets begin...
Method #1 - Thieving
Straight off the bat, you can make a fair few million from Thieving. I find this method a great way to make money nice and quick. The trick to making the most from this is to always take from the best stalls possible, as you get the most money from higher level stalls. For more tips and tricks on Thieving, please read the guide
here.Method #2 - Runecrafting
Possibly another obvious one, and it's cheap to get started. Straight from level 1, you can make a fair amount of money. For a full list of profits, and just how to train Runecrafting, please read the guide
here.Method #3 - Mining
[Forgotten how this skill works, will be reviewing this soon!]
Method #4 - Combat
OK, if you are a low level, you can go straight out to the training area with the armour you get as a starter, and begin to kill Rock Crabs. With a fairly common drop of Caskets and Dragon Halberds, you can make a fair bit of money of these fairly rapidly.
For higher levels, you will want to go to Green Dragons, as these drop Dragon Bones, Hides, various Weapons and Caskets. Also, if you are lucky enough you will get an Ancient Staff.
Method #5 - Slayer
Slayer is recommended for higher players, and you will only start to make good money once you reach a higher level, though it is possible to make a small amount from your first kill. For more information about Slayer, please read the guide
here.Method #6 - Bosses
For high level players only! Low levels run a very high risk of being slaughtered! Please only do this if you are equipped properly with a strong weapon, and good armour. There are many different bosses here, all with good rewards to those strong enough to slay them. Their drops can be sold off to shops or players for a high amount of gold.
Method #7 - PKing
When you feel you are strong enough, just use one of the PKing teleports, and try to kill the players out there. Be careful, death will result in you loosing all of your items. The better armour and weapons you use, the more of an advantage you have of killing your target, but you run the risk of losing all of that if you die. You need to weight up if it's worth risking it for a possible easy kill or not.
Tips and tricks -
Never give up, you will get there in the end, and it will be worth it.
Make yourself a list of items you want, aim for the items, once you get them, KEEP THEM!
Don't let people put you down, everyone has to start off somewhere.
