Familiarization is a D & D that will dramatically assist you. It's a bit long to RS gold describe, so go to YouTube and look up a guide to learn more about the procedure. The benefit of doing Familiarization is that you'll get a 40 minute time-span during which all monsters you defeat drop not single, not double, but TRIPLE charms.
I camped waterfiends for these levels as well. It is likely that you can get rid of them fairly quickly. The practice of Bork daily can also help increase the blue charms. A burst of rock lobsters could be attractive charms, but I find it to be somewhat of a waste because of the large loss of money that you suffer. Cannoning the most powerful demons in the Forinthry dungeon was also known to be a great source of charms. However, I'm not sure how effective the cannon actually is in the eoc.
If you're camping waterfiends, you should be likely to be able to get the charms you need to get 774 before the quest is released. Make sure you use your spirit rubies, gemstones, etc. while you train! Consider doing a quest like While Guthix Sleeps or Blood Runs Deep, both of which provide you with an incredible amount of experiences that you can make use of when summoning.
I'd recommend Slayer. Slayer exposes you to an array of creatures that will all bring you plenty of cash, mostly. You can decide from that point on which is your most preferred monster to take down.
Blue Dragons are excellent moneyHowever, you must have 70 agility it to work. Before that, you could kill Black Demons, for money possibly. The most appropriate gear for cheap OSRS gold you (considering your financial situation) could be.
