I'm at lvl 43 mage, and my target is to be able to high alch. I am not willing to spend money. Recently I am using Fist of Guthix to train, but seems ineffective. Outside, i only use fire strike: self crafted air and mind with fire staff.

 

So, how should i train? I do have quite a stock of runes of all kinds F2P. I am familiar with all within F2P world, so... advice please?

43 Magic = Superheat.

 

Superheat Mithril bars for profit/break even.

us the lvl 19 curse spell . Craft the water runes, use a earth staff and either buy the body runes or craft them. Another way to get bodies it to kill flesh crawlers. This spell gives you 29XP and if you use it with full melee armour on a monster it'll barely ever hit. I suggest the monk under the stairs in Varrock castle. He is in a cage so he can't hit you.

I agree to do this method as I did it too to get 55 mage for High Alch. I would suggest superheating Mithril ores for mithril bars but if you aren't a money spender, just superheat iron bars just like what I did :)
