Dark Reign - Army of Stone
This task and Blood from Sand can be done at the exact same time. What you need to do for this task is kill the golems inside Stillmoon Temple and loot 5 Animated Guardian Essences. As you probably already know from your previous task in Stillmoon Temple the golems are just about everywhere.
If you're doing this on only one character one clear of the zone will finish both quests and leave left over mobs. If you're doing this on a box team, you could be here quite awhile.
