has 2 spawn locations, both PH's are a gnoll shaman.
one is in a larger open room with 3 snakes and a patrolling gnoll, with a ramp leading up to a lot more mobs.
2nd is very close to the brewer. when you are coming down the long ramp from the zone in area and get to the bridge drop off the right and head to the water area with razorgills. around the edge of the water you should see a gnoll shaman with another static trash mob next to him.
