Ugh. Hyjal. Zombies. Demons. Humans! Those wings are to die for. Literally. And die, and die. You as well as me, let me tell you. Also known as the Tier 6 Raid Set, Warlocks can obtain the pieces using tokens "of the Forgotten Conqueror" that drop randomly from various bosses in Sunwell Plateau, Hyjal Summit, and Black Temple.
After much toil and strife, after crying because a guild mate needed on the helm the very first time we went in there specifically for Anou to get the helm (grr!), Anou finally won her Belt of the Forgotten Conqueror the other morning, thus completing the set.
Admittedly, I went a bit screenshot-crazy, but what can I say—those wings!
|Demon from the Darkest Crypts|
|Demon and the Imp|
|Door Number 13|
|From the Dark Heavens|
|Impressive Wing Span|
Featured above: Hood, Mantle, Robe, Gloves, Belt, and Boots of the Malefic.
A few pieces from that set are also used to complete the Sunwell Warlock Raiment, but Anou hasn't collected that set as she's not particularly fond of it. Well, not yet anyway. Personally, I don't find the belt actually matches the Malefic set, but that's that.
Now, if you want the wings on this set you must have both the hood and mantle for the effect to occur. The effect may perhaps proc on its own, but mostly it's when your character jumps. Also, for a fact, if the helm is not displayed, the wings will not proc, so even though it is hideous, Display Helm. Check!
