You’re Not the Boss of Me: Kill the following Nephalem Rift bosses.
There is an Achievement in Diablo III called “You’re Not the Boss of Me”. I find the name amusing. It sounds like something a little kid would say to a bossy friend.
This Achievement is referring to the bosses in the Nephalem Rifts. Players that manage to kill off all of the Nephalem Rift bosses that are on the list will earn the Achievement. I earned it on April 26, 2015, during Season 3.
