I will toss in my two pennies from Smarthuiyuan's blog

Right now I am trying to raise all of my skills to at least 60 so that I will not be so nooby anymore. Im trying to determine how to train each ability. Any suggestions? Also, how much would all this cost and how long could it take? Im really excited about raising my farming, slayer, summoning, runecrafting, and hunter levels because they are VERY nooby. At this time I am working on fletching and thus don't be concerned about that ability. Im trying to do this for every ten. Case in point: I'd get all skills to at least 60, then to at least 70, then to 80, etc.. Thanks!

I will toss in my two pennies for RS gold Construction. Oak Larders + Stealing Creation hammers. Seriously. Building and unbuilding them got me out of 33-70 in a flash, for the Void Series of quests. I think that's pretty much the cheapest means to do it, also, especially in the event that you plank-make all your bamboo logs. I don't remember the level need for Plank Make, however.

For Agility, I recommend doing the Brimhaven stadium + tickets before 55 so which you can go until the Wildy, which gives you enjoy 500 xp per run. It does not seem like a good deal but if you don't pay attention to what you're clicking, you'll find yourself increasing those previous five levels fairly fast. There is not a great deal of clicking involved, and the xp is really consistent. Farming, only plant whatever maximal level that you have, and then leave. It's that simple. That is about all that I can think of atm. Obviously, these are merely the methods I've used/would usage, so if someone else has an alternative opinion, then that cheap RuneScape gold is fantastic! Best of luck!
