It's too good. The only thing I don't like about it is the fact you still need the dolls to turn them in. I have the idol but am missing a doll still to turn in for another enchant for Faceplate.
Dolls are easily obtainable solo. There are 2 hoodoo piles I find that are easy to solo to. The one at the beginning near the bats, ridiculous fight, its sad how easy it is to kill them. And one in Jin'do's room guarded by 4 elites. Harder, but still not too difficult to solo.
Have someone invite you into a raid group and go in and get your 2 easy piles. Make sure you take off all your gear before you loot incase it aggros everything around you. If you don't get a warrior doll, have someone else invite you and try again. Since looting the piles doesn't save you to the instance, you get a fresh instance everytime you get a new invite. It may take a bit of time, but it's possible to just run those 2 piles over and over again until you get it.
You need one [item]Punctured Voodoo Doll[/item] (make sure it says "Warrior" on it) and one [item]Primal Hakkari Idol[/item].
The Voodoo Dolls are looted from Jinxed Hoodoo Piles scattered around the instance. The Idols drop from both Jindo the Hexer and Blood Lord Mandokir. Each boss drops one Idol per kill and only one person can loot it. The Idols are BoP.
Yeah more or less, depending on gear and how many of them are familiar with the encounters. If you only need one Idol and aren't too confident about your group, definitely go for Bloodlord since the fight is much easier than Jin'do. As little as three people in full TBC epics could probably handle Bloodlord.
