Masteries | Player profile League of Legends Guide

With each profile level players are rewarded with so-called Masteries Points, so you can have as much as 30 of them. They can be assigned freely into 3 mastery trees: Offense, Defense, and Utility. You can have up to 20 Mastery Pages, which can be created for free (unlike rune pages, they do not need to be purchased). Masteries can be freely changed and adjusted to needs of particular champions, even right before a game starts, during champion selection. In one of the pictures in this chapter there is an example of a mage's Masteries tab. Here, 21 points have been distributed in Offense tree, in order to increase magic power, damage, and magic penetration, as well as lower cooldowns. Defense tree has been skipped, and the remaining 9 points were spent in Utility tree, so as to improve mana regeneration, reduce summoner spells cooldowns, and increase duration of buffs by 20%.
