Once you reach level 50 and have chosen a Build for your Necromancer, you will want to start picking out the best armor to complement it. The Armor and Legendary Aspects are designed to enhance either a group of Skills, your mobility, or give some kind of utility. Some of these will be best for a specific Build, but many will be good for most, if not all Necromancers.
