I can't tell if that's sarcasm or not, but I know Demonic Thrones are around 12-13m Xp an hour, but that's a cost of like 13B RSGP an hour. Fletching bolts and arrows can gain upward to around 1.5mxp an hour. Prayer is simple, just do frost dragons and no-life gilded altars. Really anything that is a money skill can be trained quickly. Magic, Range, Smithing, Cooking, Firemaking, Herblore, Dung Floor Paying. If you had the money, you could take care of the skills you can buy in the first month then work on Farming, Slayer, Mining, Combat Skills, Agility, Summoning for the next 11 No-life. I heard that Drumgun or some other top ranked person has around 1600-2000 Days logged on Runescape. Thats like 6 straight years of your life playing and clicking. -.-
