from my experience, mining is a good way to go. get to 15, hoard about 1k iron ores and sell them 100ea on world 1. then get a rune pick, continue mining until you get to lv 60, then start coal
:P I did over react a bit, just didn't like to be called "we are not helping" when the answers has been given, thats all... *Plunges into ice bath* there :P
you cant hide against the brothers so you have to pray through some of them at least Well, I only use prayer when im against dharok i am surprised that you survived well against karil and verac without prayer...
I think you got the Zamorak and Saradomin pages mixed up Guthix : around 50k (green) Zamorak : around 200-250k (red) Saradomin : around 100k (white) you need 4 pages to fill a book (pages 1 2 3 and 4)
and if you get your sources right, you can make a good profit from magic longs, not to mention the convinience of being able to make your own Magic Short Bows.
you cant kill the brothers more than once (except for the ones in tunnel, which you can get multiple spawns) unless you open the chest, which resets the run.
provided you the appropriate smithing level, thats would be a bit more balanced (so that we dont have d skirt hoarders, change them and sell for a profit...)
Shilo Village Gem mining will be your best bet, mine them. cut them and sell them in the village (1 at a time to maximise sticks). Alternatively Rob HAM HQ for the gems, you can also get clue scrolls as bonus.
go to canafis, buy a sample bottle from the general store there, and get out your pestle and mortar. then go into mort myre swamps and kill a snail. use the pestle and mortar on the snail while you have the empty sample bottle. you should now have made a blemish snail sample like the one gerrant gave you. Make the oily rod as normal
