Raest's Gift

Empowering Trait Questlines
There are seven questlines, providing variation among roles and specializations. You can pick up this quest after earning 35 traits on an artifact weapon. The quest starts from The Broken Shore: Investigating the Legion and Khadgar encourages you to find Mysterious Runebound Scroll from a random mob on the Broken Shore. Which gives you Legion Threat: Suramar and then Legion Threat: The Necromancer

This is a guide for the other specs.
