Ghostly warriors shed tons of runes, and RS gold therefore are fairly good exp, also. All you need is jenica's ring after completing summer's end, and utilize the portal close to the axe hut. It would be a good idea to deliver a fort bracelet on you, in case a rev tries to teleblock you and you also can not get in the portal. They respawn extremely fast. If you're in a world with roughly 1600+ people, even only 2 minute will keep you attacking none stop. They fall only a few runes and stone, so not the best, but the exp is definitely something to consider.

Guess that about sums it up. Try to use super attacks when you are training, you'll hit a whole lot more often and get much more exp\hour. Another good\cheap method is to use a dbaxe special, then drink a restore potion, then top it off with an attack potion. Cheaper than using the super strengths, but it does about as good as a job. Probably a few good things I did not understand about\forgot to mention. My plan is to get about another 1500k and go back into buyin ores and superheating mith and selling bars Until lvl 70 smithing. The first method is faster to mine, but I would have to do it more often. Second method will get cheap RuneScape gold me near 69 smithing though. If you've got a much better method please let me know.
