Easy Money+Runecraft lvls
I found this, with the new grand exchange, this costs no money 2 start, but easy as this: Do rune mysteries quest, and mine ALOT of rune essence, like 3k...or get it, 550 rune ess will get you about 16 runecrafting lvls (if ur lvl 1) but at lvl 22 u get 3 per essence, and airs sell for 17-20 each, and rune essence for 40 each, so once you start getting 3 each, your making a good 14-17 extra per ess, and after a good 3k, ul be like lvl 40 xD so ul be getting 4, but ul have a good, 7k air runes, which you can sell for double/triple what you would just selling the ess...takes awhile, but gives you good runecrafting and good money...works with other runes as well :)
