Good Luck, but you don't really need Fast Free Laws. Solo nats like i did from 80-91 :P I am sure you will make it although, it will be alot harder not since the price of natures has dropped and you basically get nothing in return for your investment in pure ess.
Well this update along with the new gold exchange, killed the rune market. I use to make nature runes for profit now I can't even sell 4k nats for 1 million GP. All the other skills I need to max out the price for raw materials is absolutely insane. Time to retire for a final time
