My granite maul special takes my whole bar, I'm not rushing with it lol, I am clicking spec once, then I would attack kalphite queen (testing combo ) but it would take my whole bar away, so how could I change it from using 100% spec to like 50% spec ??, please help. I am using project insanity (Pk Forever..aka Wilderness ReLoaded) thank you!

I know I am always asking for help! sorry, But thanks!
