Summoner Mastery

A summoner is able to focus their intense magical training into three specific categories, which collectively are known as masteries. Some of the more advanced masteries require not only a working knowledge of previous masteries within a single category, but also the knowledge of a specific mastery. As a summoner gains levels of power within the League, they are able to select which specific areas of interest to focus on. Summoner masteries are not set in stone; based on the type of champion you wish to control in a battle arena, masteries may be changed to better suit a summoner's needs.
