Wanted: Knucklerot and Luzran is about killing two elite abominations and turning in their heads. You receive the quest by reading the wanted poster next to the inn in Tranquillien.
A bounty is hereby declared for the abominations known as Knucklerot and Luzran. These dreadful creations of Dar'Khan are extremely dangerous and have been sighted patrolling near the Howling and Bleeding Ziggurats. Individuals seeking to claim the reward must present the abominations' heads to Deathstalker Rathiel as proof of the deed.
You have something to show me, <name>?
Ah... Luzran and Knucklerot! Not looking so tough anymore, are you? I can see you're still looking ugly as ever.
Take one of these rewards, <name>. You've earned it.
The player must track down Knucklerot and Luzran, two abominations that wander around the Ghostlands. They start at one of the two ziggurats (Howling Ziggurat and Bleeding Ziggurat) in the center of the Ghostlands, and have different patrol areas. Luzran tends to patrol the path from Windrunner to the the ziggurats, then south along the Dead Scar to the gates of Deatholme. Knucklerot has been spotted near Goldenmist, Windrunner and Suncrown Villages, as well as Windrunner Spire, and it appears he follows the pathways.
