Alright, until you consider flaming me, let me say, this really is a question towards a PLAN I've, not towards"the way duz that I maek muneyzz?!!!! 1111!!! 11!! 1!! 1!! 1! One!" . Now after that, my plan, is simple, to OSRS gold create enough money to get from 31 prayer to 43 prayer in F2P, using large bones. I just dropped a lot of cash after dying, but I have 10k left. I've chosen to make some use of this 10k. My strategy is in measures below: Withdraw 6k from my own bank. Use that 6k to fish lobsters in Karamja, with 60gp/trip. After conclusion of angling 2600 lobsters (6000gp/60 per trip 100 trips * 26 lobsters per trip = 2600 lobsters) sell the lobsters for medium G.E price in the G.E to get 824k (2600 lobsters * 317 gp = 824200gp)
Buy 2364 significant bones for 817944gp. (2364 big bones * 364 = 817944) Have 6256 left. (824200 - 817944 = 6256) Maybe do it , but with Swordfish? (Make around an estimated 400k over with swordfish) Well, there it is. Any advice/suggestions on what I should do along the way? Oh, and if it matters, my fishing level is 53, and using a planner, then it will be 63 after this. Incidentally, if your wondering why I just don't get it done with swordfish at this time, its because it is going to take too long for me to fish, using only 53 fishing, and plus, its a bother for me to fall any unwanted Tuna I have harpooned up. I am also F2P. Thank you for any suggestions.
If you are doing the bosses you'll require a whole lot better armor. Look at the God Wars Dungeon guide on the Website for more information on that. If you go in with only full rune, it will not take you long to get slaughtered. You will require barrows/god armor (The kind you get from the dungeon, like Bandos) a LOT of food, in LEAST 80+ ALL battle stats and 70+ Prayer will make your life a good deal simpler.
In short: Get more income up and down your battle stats . I would recommend you get each combat level up one level first, then try and get Prayer to 60, bare minimal. Try doing it through slayer for some decent money, which you actually need. Rune is fine. Barrows is much better but rune is good if you don't have the money to spend. You may even array him. If you go with a group of 4/5 you can last maybe 10 kills with rune. Probably 15 using Barrows, it doesn't actually make that much of Old School RS Gold difference.
