Defense Mastery Tree (2012)

Defense Mastery is one of the three Mastery branches. Its main focus is to give advantage to defensive actions like armor, magic resistance, health, and health regeneration among other defensive buffs. The Summoner Spells Heal (Tier 1), Revive (Tier 1), Cleanse (Tier 4), and Fortify (Tier 5) are improved by this Mastery. It would take up to 31 points to max Defense Mastery out.

This Mastery branch is commonly used alongside the Utility branch by Summoners due to the fact that they both serve useful to Tank or Support-type Champions.
