I have found on any given day at any camp you can go 10 or more PHs with no named spawned the the buggers will spawn 5 times in a row and drop th rare every time LOL..
If anyone could give a detailed description of where he spawns i would greatly appreciate it. Where are the slave areas at? Is it near the courtyard area where all the golems are?
When you go to kill the Undead chef, you go down the ramp from his room. There are 3 guys in this room with a fire in the back. go across the room to the stairs and you will see water. that it the enterance to the slaves.
Oh, and to get to him, you go into the LEFT entrance into the slave areas. Take the hallway down, and where it Y's, take the right path. His PH is a revenant.
