PH is the mob that stands next to the fire, outside the building that is closest to the druid ring. The building has one mob on the porch and one inside, usually archers or shaman. The PH can be just about any kind of gnoll.
I was able to two-box him very easily with a level 75 beastlord with only moderate gear (approximately time level, about 11.5k hp / 1.6k ac) and a 72 druid (950 aa's, Anguish gear). By the end of the fight, which didn't last very long, both toons were still around 70% mana.
Spawn rate appears to be about approximately 20:1, 20 min respawn of PH. Usually see him pop about once every 6 - 7 hours of constant clearing. Drops arm mold about 30% of the time for me. For me, mold has always been silk. Always rots.
Best way to do this camp is to kill PH, go do something else for 19 mins, kill PH, repeat for several hours. If you're after arm molds, might want to try to spawn the named leapord instead. Haven't tried that named myself, but the spawn rate has to be better than chef and probably less contested.
I saw him spawn back to back, with leather arms both times, and the spirit mantle....then hours then spawn with no arm mold, just spirit mantle...then hours...spawn with no arm mold, just spirit mantle...

Dropped https://everquest.allakhazam.com/db/item.html?item=51473 along with a Veil of summer, entropic cleaver and razor sharp obsidian blade. My beast and shaman were the only ones in the zone at the time. So the drop wasted.
