Zek, the Scourge Wastes: The Siege [Raid]

trying to do it solo. how do i spawn the weapon of war and how do i initiate challenge mode?

In a brand new instance, there are 4 bosses already up. One boss (I forget his name) wanders around. DO NOT KILL HIM. One of his buffs indicates that he is linked to Sanctifier Goortuk (boss #5). The Sanctifier spawns when the 3 static bosses die. If you pull the Sanctifier before killing the wanderer, the wanderer will aggro, and challenge mode will activate (challenge mode is just fighting both at the same time). Once you kill the Sanctifier in challenge mode, the Weapon of War spawns in the arena/altar area.

^ That. Just don't kill the named that is wandering around.

so save the wanderer till last? i
