This is our third or fourth kill (can't remember right now) of the Heroic Nefarian Encounter in Blackwing Descent. We brought this fellow down rather quickly when we first killed him (in the same ID we killed Heroic Al'Akir). This was our last Boss before we went to Sinestra (we killed Cho'gall Heroic even before Al'Akir).

However, we always mess up with Nefarian in Phase 1 and mostly in Phase 2 due to just shitty playing sometimes. So we always need like 5-6 tries to down him, and usually somebody dies during Phase 3. What a pitty. Nevertheless: Enjoy!
