Useless information all over this board. If I had a nickel for everytime I saw "could xxx solo this?" without having read down the board 5 posts to where it was answered, I'd be rich.
Anyway. This camp has 3 spawns: left, middle, and right. The one on the left is always a trash mob, either a knight or a wizard. The middle one is either the Ghoul Supplier or a PH. The right one is either the Ghoul Assassin or a PH.
The spawn time on all three is about 28-30 minutes. The Supplier and Assassin are not particularly rare spawns, spawning somewhere between 30 and 50% of the time, I would say.
The Assassin seems to drop the mask most commonly, and slightly rarer, the dirk. If he's carrying the dagger and it procs while you're fighting, then you know what he has.
The Supplier usually drops the Light Burlap Sack (65% Weight Reduction) and rarely drops the Thick Banded Belt.
Around level 50 it would be possible to solo this camp. The monsters don't hit very hard, but if you have to break it and it's 3 wizards... they can take you down pretty quick. Best to go in with a partner if you can.
