Onyxia Key Quest Guide - Horde

Quest: Warlord's Command
Start: Warlord Goretooth
Where: Badlands
Quest Level: 63; attain: 55
XP: 8550
Has an item reward.
Group: 5 man group only
Notes: Warlord Goretooth doesn't directly offer Warlord's Command (there is no ? above his head), you have to go through his dialog first. This daunting quest has you 5manning LBRS to kill 3 bosses and collect a ground spawn that is randomly placed. The bosses are: Warmaster Voone, Highlord Omokk, and Overlord Wyrmthalak. At one of those places you can find the "Important Blackrock Documents" that are also needed for the quest. Now, actually from what I can tell, Wyrmy doesn't have them at his spawn, but instead is outside on a ledge near another named guy who you spawn.
