The Offense Mastery Tree is one of the three Mastery branches. All masteries were redesigned on November 15, 2011. The information from this article refers to the version of this mastery tree used before the redesign.
Its main focus was to give advantage to offensive actions like physical damage, magic damage, critical strike, armor penetration, among other buffs. The Summoner Spells (Tier 1), (Tier 1) (Tier 3) and (Tier 5) are improved by this Mastery. It would take 31 points to max the Offense Mastery out. This mastery tree benefits AD carries the most, while also providing useful benefits for casters.
