10th December 2012, Patch 5.1.0 ● Burning Legion EU - Aventurka
Demonology + Voidlord ● 477 iLvL
Talents: Dark Regeneration, Mortal Coil, Dark Bargain, Burning Rush, Grimoire of Supremacy, Kil'jaeden's Cunning
Glyphs: Demon Hunting, Imp Swarm, Soul Consumption

Difficulty: ★★★★ Hard

The most annoying thing in the whole fight is Curse of Torpor used by Adherents. This curse increases your ability cooldowns by 15 seconds. Remember to not stand in Death & Decay.
P1: This phase ends as soon as Lady Deathwhisper's mana shield is down (dmg done to Boss drains her mana). The priority is to kill all adds (especially Adherents) as soon as possible. Deformed Fanatics must be kited, otherwise you will die from their dmg. Use Metamorphosis to quickly kill adds. Adherent's Shroud of the Occult (deflects all harmful spells back to their caster) absorbs 50k dmg before breaking - use Voidwalker to do it. Unfortunately, I forgot about that and so the fight was a lot more difficult than it should be. As I said previously, I like to make life difficult :P
P2: In this phase, priorities don't change. You deal with adds as well as in phase 1. Touch of Insignificance (reduces target's threat generation by 20%; stacks to five) should not be a problem. Use Dark Apotheosis or defensive cooldowns, when your HP falls dangerously. You should avoid Vengeful Shades (ghosts). Good Luck and Have Fun!
