i got more money this is souly about runecrafting :L
only things is im not sure what to rc from like 50+
I would say go for it, Runecrafting ends up to be a very good money making skills as you get it up higher. However I do not see how you will need to use 16m on Runecrafting, considering you usually make money not spend it while training Runecrafting. If you are training with a more expensive method, I would suggest reconsidering and using a method that you can get exp and money from.
It is one of the worst actually.
I fail to see how you actually lose money on runecrafting, let alone, lose 16m just for a couple of levels. Unless there's a new method on fast exp with loads of cash.
Anyways, like others have said, craft whatever you can make, as natures, astrals, and laws are worth more than one pure essense, so do that. You can either craft using Spirit Graahks if your summoning level is 57+, or preferably the abyss.
No, don't spend 16m to get runecrafting levels. Use that 16m to buy summoning to 57 graahk pouches duel rings and PURE essence, then you make your money back and get 99 rc easily.
