Armor Skills in Elder Scrolls Online grant benefits to the player for wearing that type of armor. Light Armor focuses on Magicka, Spell Resistance and Spell Critical. Players who utilize Magicka bases abilities above all others will use this type. Medium Armor focuses on just the opposite. Players who specialize in this type will gain bonuses to Stamina Regeneration, Critical Strike and Stealth. Heavy Armor focuses on protection above all else. Players specializing in this Armor type will gain bonuses to Armor, Spell Resistance, Block reduction costs and Healing Taken. Players are free to mix and match armors, thus gaining bonuses from the different Armor Skill Lines is possible.
Please see the Armor page for details on what protection each types grants and the sets page for information on sets.
