-A recommended place to find Runes is the Dark Knights Fortress. It is directly north of the Dark Knights Fortress and northwest of Edgeville. You can find all non-member's runes up to chaos with short respawn times. However, be aware that it is common to find team PKers waiting for someone to come near. Also, be aware of the Dark Knights in the castle as they can be a tough fight for low level characters, and for higher level characters who might also have to contend with PKers.
-Head to the Grand Exchange in Varrock. Either set fire to your own logs, or wait for someone to do it for you. Pick up all the ashes. Sell them at the Grand Exchange. If you fill your inventory with ashes, it will be a quick 300 to 400 gp.

-To do this trick you must have 28 Thieving and know how to get to Relleka. Go to the helmet shop in Relleka and go upstairs to find a chest. It contains one Nature Rune and 3 gold pieces.

It will turn a lighter color when you open it, and you must wait a few seconds until it turns back to the darker shade of brown to indicate that you can get another Nature Rune. These can be used for multiple spells and can also be sold at the Grand Exchange for about 300 to 400 gold pieces each.
