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.
It is not a Seasonal Achievement. It is a Career Achievement. Players can earn this one at any time just by doing Nephalem Rifts until they have defeated all of the required Nephalem bosses.
I earned the “You’re Not the Boss of Me” Achievement while I was playing my soft core Crusader. The game was set to the Hard Difficulty level. I’m pretty sure that players can earn this one in any difficulty level.
The Nephalem Rift bosses a player must kill in order to earn the “You’re Not the Boss of Me” Achievement are: Erethon, Cold Snap, Man Carver, Blighter, Agnidox, Perdition, Voracity, Perendi, The Binder, Rime, Ember, Stonesinger, Crusader King, Bone Warlock, Tethrys, Eskandiel, Infernal Maiden, Raiziel, The Choker, Bloodmaw, and Sand Shaper.
Most of the time, Ember looks like he does in the above screenshot. One time, he looked completely different.
