i want to get 95 herblore to make overloads, so i was thinking of grinding the way there with serum 207s etc. But then i'll have to make a load more extreme potions to make the overloads, which is a lot of herblore exp wasted, so would it be best for me to make extreme potions all the way to 95? or just part of the way, and how much more expensive would it be. Im just so confused >_> Can anyone else tell me how they did it?
