Simple really, u buy 28 glorys optimum... you craft using your pouches :- say your 75 rc, you make 53 nats a run with a 1 click tele in your invent just in case :) That takes around 1minute, without any pkr's or trouble getting in to centre of abyss. That is - 15,900gp a run.... minus ur price of ess 5,300 gp (approx)... your making a good 10k profit per 1/2 mins.... :) PS on average a day i make around 4/5k nats, im 78 rc:) Hope that helped, plus once you use all your glorys, get a games necklace (make one from a sapphire and a gold bar) teleport to the games room in burnthorpe and then run to heros guild.... charge your glorys and get back crafting.
