If you are into summoning, waterfiends can be good to OSRS gold try. About 80 percent of the time they'll drop a crimson charm, and also their falls are not that bad . They are just down the whirlpool you gain access to while performing barbarian training. Be use to utilize crush attacks on them, they are very resistant to any thing else. Bunyips are GREAT here, their special lets you eat raw fish to heal (they fall a good deal of these ), and if you dont have to heal, you can use the raw fish on it to turn them to water runes (they also fall a great deal of water runes).
Ghostly warriors shed tons of runes, and therefore are pretty good exp, also. All you will need is jenica's ring after finishing the summer end, and utilize the portal near the axe hut. It'd be a great idea to bring a fort bracelet on you, in case a rev tries to teleblock you and you also can't get in the portal. Giant skeletons in Damis lair are pretty great, also. They respawn extremely fast. If you're in a world with about 1600+ individuals, even just 2 minute will keep you assaulting none stop. They fall just a few runes and stone, so not the best, but the exp is definitely something to take into account.
Guess that about sums it up. Try to use super attacks when you're training, you'll hit a whole lot more often and gain much more exp\hour. Cheaper than utilizing the super strengths, but it will about like a project. Probably a few great things that I didn't know about\forgot to RuneScape gold buy mention.
