I don't know if you bot or anything, but if you do, agility would be a sick 99 to have. Besides that, I think you could get either 99 Magic (I really like the cape for this one) or 99 Fishing (you would make a lot of money). Just my opinion though.
If you are still after a bit of money but something that is decent exp, try either Hunter or Fishing. Both will make you a great amount of money. Wth...do them both next! D:
^ That is by far the prettiest cape, imo. If you have decent money you should definitely farm, mostly tree/fruit tree seeds and do herbs do even out the cost.
