Hmm, skills cost money and your not going to make a profit from this. You can't try and decrease the loss of money through the skill. You will need 7,358 high alch's in order to get 80 magic. I would just suggest keeping 7,500 nature runes and selling the other 2,500 for money. Use that money and any other money to buy 7,400 Yew long's 600 each since you don't have 70 fletching. I don't see how you can make any profit with your circumstances. :wall:
