After seeing the spawn point in the SW corner of the zone STILL camped, I decided to kill some vamps. Checking track out of habit, I saw 2 tormented on track. One was at -1000, -1150 on the side of the hill by the SE Coterie "village" - Southern hill in the village valley, halfway up on the north face. A grimling orefinder or darkwing bat popped there as a PH if the tormented didn't. This isn't such a safe camp if you can't handle dire sonic wolf adds.
The other spawn point is on the hill that butts up against the southern wall of the big Coterie castle, right next to the front door. He was just standing on top. An alien (soldier normally) or darkwing bat pop as his PH. No adds wander up on this hill, so it's safe to camp this spawn, but be aware the PH's spawn in about a 30' circle.
One more piece of advice. If you have the ability, camp any of these spawns in wolf form. If you are a doggy, the tormented and/or his PH's will aggro you automatically. You won't miss a PH spawn this way.
Good Luck.
