I was wondering, is the Leech Special Attack curse worth getting? I currently have 82 prayer, and it would cost me roughly 25m to buy the dragon bones for 86.

maybe if u pvp alot but really i dont personally see a use for it except stopping D claw and AGS rushers and even then i think it takes 1 turn to activate.

I wouldn't get 86 prayer just to be able to use leech special attack. It's fun to mess up people using 50% or 100% special attack weapons. But if you're planning to train prayer, you may as well shell out the extra millions to get the higher level prayers. And if you don't want those higher prayers, you should just save the money.
