These achievements are associated with the armor sets released with 6.0. There are 0 legacy points spread between 68 achievements in 5 subsections. Each achievement requires collecting all 7 pieces of the armor (Head/Hands/Forearms/Chest/Waist/Legs/Feet). As of 7.0 you can purchase all armor sets from S3T-BNS on the faction fleet. If you own a piece of gear, but it has not counted towards the achievement you may mail it to another character in your legacy to get the achievement to trigger.
