All 2017 Summoner Masteries
mastery was an area that a summoner was able to focus their intense magical training into, categorized into three specific categories, which were collectively known as masteries. Some of the more advanced masteries required 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 were able to select which specific areas of interest to focus on.
Summoner masteries were not set in stone; based on the type of
champion you wished to control in a battle arena, masteries could 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 could only spend your masteries up to 30 ("re-spec"). Additionally, the available masteries were revamped on a semi-regular basis (once every season or two).
There were three types of trees that your summoner could have developed in before the system was dropped:
Note that 2017 mostly retained 2016's masteries and 2015 mostly retained 2014's masteries aside from balance changes. As such, there are no pages for Seasons 2017 and Season 2015's trees.
Mastery pages were released in patch
V18.104.22.168b. Mastery pages could be stored and, later, chosen similar to Rune pages during champion selection. You could have up to 20 Mastery Pages.
With each level achieved by a
Summoner, the Summoner also received one mastery point, capped at 30 mastery points, which was the maximum summoner level. Each mastery took one point to increase its level and each tree contained at least 37 points worth of masteries, so even at top level the Summoner was not able to completely fill any one tree, let alone all trees. This added a strategic element to your selection of Summoner masteries, as you could choose masteries that synergize with your champion, spells, and teammates.
It is important to note that most masteries required points in the tree. When moving to higher levels in the tree (higher "tiers"), one would 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 had at least 18 points (so level 18) to acquire one of the last (Tier-6) masteries in a tree. These were called Keystone Masteries and they greatly impact a champion's playstyle.
At all times, only a total of 5 points could be put on odd tiers in a tree (1, 3 and 5) and only one point could be put on even tiers (2, 4 and 6). For example, if one put 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.
