I am trying to get the ranged level required to do the new elf quest (75) from my current level (62). Could you recommend the fastest, most cost efficient, and both fast and cost effective methods of getting these levels. Thanks.

Besides the expensive method of chinning. You could try one of my favorites, cannoning. But Wait! Doesn't cannoning lose money? Not if you do it my way. You should try cannoning ice trolls on Jaitzo. You could also pop on a SC ranged helmet for extra exp. I hope this helps.

Fast way would be Throwing Knives on creatures. Yaks would probably be one of faster methods. Fire giants would net you some money. Cost effective would be Black Knives. You could use a higher Knife but it probably wouldn't make much of a different.
