Invoker is a ranged intelligence hero who is very difficult to master. He is unique in that he possesses a total of 14 abilities in his arsenal; three of them – Quas, Wex, and Exort – are reagents and one is his special ultimate Invoke. The three abilities he learns throughout leveling up can have three instances, which serve as the basic ingredients or components for him to create a new ability using his ultimate. Once the reagents or elements are combined, he can invoke one out of ten different abilities.
