I decided to publish this guide because of a friend of mine who said i should, this guide will go over the exort build which i have developed myself over 400 games of invoker in dota 2 and more than 200 in dota 1, ive used it in competitive matches and it has proven succesful, it will cover reasons for item choices and how to use invoker's skills properly, now i will leave you with this paragraph of text and a guide for invoker.
