A Runed Stonegrabber  

Their are three spawn locations for stonegrabbers and at least three of the special stonegrabbers spawn at these locations. If you head due sout from NL entrance you will come on three rock formations that are about in the middle of the zone. The first formation has two spawns and the other two each have three spawns. The stonegrabbers are not social and almost all are dark blue to a 53 warrior and 48 shaman. Spawn time is quick enough that above duo was unable to keep all seven of the spawns dead at any one time. Wandering wolves will agro from time to time but generally it is a safe, easy camp. The runed, light and lunar stonegrabber each spawned during the two hour camp, all at different locations in the seven spawn camp. Hope this helps.

Dropped a "Runed Ring of Earth", Magic, Lore, 1 sv Disease, 1 sv Poison... No idea what's the use of it yet, as all the twilight armour components are statless... or so I would assume is the trend I've seen.
