A Mastery is an area that a summoner is able to focus their intense magical training into, categorized into three specific categories, which are collectively 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 of Legends, 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 can be changed to better suit a summoner's needs, simply by pressing the "Return Points" button to completely reset your masteries and allow yourself to choose others in which to spend your points, you can only spend your masteries up to 30 ("re-spec"). Additionally, the available masteries are revamped on a semi-regular basis (once every season or two).
Trees
There are three types of trees that your summoner can develop in:
Mastery pages
Mastery pages were released in patch V1.0.0.118b. Mastery pages can be stored and, later, chosen similar to Rune pages during champion selection. You can have up to 20 Mastery Pages.
Attainment
With each level achieved by a Summoner, the Summoner also receives one mastery point, capped at 30 mastery points, the maximum summoner level. Each mastery takes one point to increase its level and each tree contains at least 37 points worth of masteries, so even at top level the Summoner is not able to completely fill any one tree, let alone all trees. This adds a strategic element to your selection of Summoner masteries, as you can choose masteries that synergize with your champion, spells, and teammates.
It is important to note that most masteries require points in the tree. When moving to higher levels in the tree (higher "tiers"), one will encounter an increasing prerequisite of 5(+1) points spent in that tree. For example, in order to put a point into Feast (a tier-2 Ferocity mastery), one must first put a total of 5 points into the tier-1 Ferocity masteries, and to put a point into Bond of Stone (a tier-6 Resolve mastery), one must have 17 points in other Resolve masteries. A summoner must have at least 18 points (so level 18) to acquire one of the last (tier-6) masteries in a tree. Those are called Keystone Masteries and they greatly impact a champion's playstyle.
At all times, only a total of 5 points can be put on odd tiers in a tree (1, 3 and 5) and only one point can be put on even tiers (2, 4 and 6). For example if one puts 5 points in Wanderer (tier-1 Cunning mastery) putting points in Savagery (also on that tier) will remove points from Wanderer for a total of 5 points on that tier.
