I strongly suggest you do some prayer based quests last. If you begin prayer, you will not be that good until greater combat (such as 75 strength+). This helps to keep most people motivated. You could also stop at 50 assault for OSRS gold granite mauling first. Remain legit man. 90 percent of pures (that is a made up statistic, but it's likely unfortunately accurate) these days are botted, combat brace wearing nubs.
In my explanation, I'm are assuming that you are getting 95 prayer from roughly 75ish. You can add on your own numbers and follow exactly what I did to see if its different. Therefore a 35m difference in the price and also a 15 hour time difference. Therefore, if you value your own time at 2.3m+/hr it is worth it to use frost dragon bones. But this is assuming you have the cash already, that you dont, but if you want to collect the frost bones to make this possible you can.
Now for the collecting the bones. Everything depends on how much you really make/hr. Should you create 2m/hr then it is 90 hours to your frost bones and 72.5 hours for the dragon bones. Now adding how long it takes to use the bones its 97.25 hours all of the way through for dragon bones and 100 hours all the way through for Frost bones. And you must answer for yourself if 2.75 hours is worth 35m. Therefore it's better in your situation to utilize dragon bones, by 2.75 hours gap and 35m. Dragon bones are all about precisely the same period as frost bones, but you save 35m.
I don't think so. For instance, if you press Esc to close your bank it would need to use coordinates to obtain the X to close the bank, which makes it illegal and automatic. Also pressing F10 to change to lender and equipment, that isn't 1:1 input to output. Going from equipment to bank is a number of purposes and is also impossible to do with 1 click unless you are hacking the game to allow it to do that. If this isn't true then develop on which you want it to cheap RS gold do, I didn't really know what you were asking but I gave my own attempt.
