The most basic farming patches of RuneScape include allotments
Also, the helm, will an arma helm more effective? Arrows do not return to you at the end your game. I've heard it takes 7-14hrs, i never bothered recording time, however it was around 10hrs RuneScape Gold. I wouldn't recommend using void especially if you're planning on renewing your membership.
First off, I think the Runcrafting minigame, known as the Great Orb Project, is one of the best ways to earn cash for f2p. So get 50 RC ASAP! Train Atk and Strike Men in Edgeville. Move on to the Guards inside the palace of Al Kharid, and finishing off with Flesh Crawlers in the second Stronghold of Secruity. The best place to watch Flesh Crawlers is the south-east corner room.
Range: You could train it with the males too, as well as at cows. You can use the safe spot between the two feeding bowls to the south of the Lumbridge cow patch. After you've hit about the 20 mark, you can move towards the Minotaurs on the first level of the Stronghold of Secruity. Find a room that suits to your taste and then secure it within an enclosure.
They drop iron arrows quite often, so it's basically free training. Around about 40 to 50, train at Hill Giants until 50. When you're 50, you'll be back on the flesh crawlers in that south-east corner room. You can safe spot these within the square near the closest door to the wall. This can be done for both doors. (You can easily score 75 Str/Range in flesh crawlers.)
If you want food Go to World 1 where fishing enthusiasts power the place, offering free trout/salmon. Magic: Train on the mage dumbies until they stop you from doing so. You will by then obtained the magic level needed to perform a few curses. You can cast these curse spells on the Zamorak monks in Varrock Castle RS 2007 Gold. Varrock Castle, directly behind the steps.
