Kebabs are RuneScape gold amazing food if you have the patience to buy them. Power Ammy is better for coaching until 70-ish Str. Use your mind, don't do something stupid you will end up regretting. Iron Gauntlets out of FoG are the best melee Def gloves a 1 Def pure F2p could possess, but are more difficult to obtain and fix than Green D Hide Vamps. Greater Magic lvl = Higher Magic Def. Regardless of how long it takes, and I am assuming you don't play a whole lot, or you did not today, since 25 Str is dreadful. . .45min. :D I am scared to even supply you with an estimate honestly, however w/e, ~4 months.
I have NEVER done Bandos throne room first off, so I DON'T know everything there is to know about this. I have however read manuals and so on, so that I understand abit. I am aware that a few of the gain comes from Granite Maces, but most of it comes in stone which you cut into bolt hints and sell. There is also some alch-able things too, which provide some profit aswell. PS: Since they drops stone frequently, the Gem Bag out of Dung are a wonderful advantage in your inventory.
I HAVE done (And love) Unicows. 3 in the event that you've got the Ardy Cape, use it, if not, do it. Since these fall Unicorn Horns 100% of the time that you ALWAYS profit. You can never not gain from them, even if you are an idiot and suck at Runescape, you can gain from Unicows.
I prefer continuous income/drops that way I've some kind of business going on, where I'm not confused as to if I'll profit (Being unsure annoys me.) I'd say that Unicows are much better, just because: No expertise in Bandos throne room myself to actually compare. Odds to profit are more continuous killing Unicows. Aside from the pursuit, and being able to kill a lvl 25, there is barely any prerequisites for using the Tower of Life. As to using Bandos throne room, I assume there's afew pursuit that are of moderate difficulty, and you want either high def, or prayer (And cash.) There's NO WAY people can steal your kills at Unicows, because you summon the beast, and only you are able to kill it. ASSUMING people can steal kills in Bandos throne room since in cheap RS gold the guide I read, it said you could bring a friend with you to assist...
