Death Shake, also completely broke the AI of two healer mercs while my beastlord's warder was tanking, not that the cleric box I had was able to heal the warder anyway. Cast, cast, cast and the spells never landed. Not stunned as there was no stun message, Death Shake only fired four times as far as the cleric could see (and I kept the cleric a ways back for her own safety), and she wasn't getting casting interrupted or other error messages. She'd complete the cast and the spell just went nowhere. Warder died (because of course it would when the cleric and the beastlord are unable to heal it) and my shadowknight grabbed aggro. Suddenly the healer merc AI turned on and my cleric box could land heals on her. Should have just chained heals with my cleric rather than trying to get the warder back up because the sk died then the beastlord in quick succession. Cleric spammed Word of Resurgence just to see if the dps merc could finish Keramar off and no stuns/interrupts from Death Shake there either. Gated her out to rez and assess what happened.
This guys ph can be a non-named dog, or a looter/hungry guy that roams between the first building and the building with the Husk of Starvation mob. I noticed that when pulling the roamers in between the building sometimes they spawned a looter/hungry, others it was a non named dog.
This mob spawns on the arms level in the northern part where you shoot down the Windsong transports for the Protect the Arms task. Just NE of Blacksmith Zojirath is a building. One placeholder is inside the building. The other PHs roam on either side of the building. The roamer to the left of the building is always a naeya. Placeholders on the right (east) side can be either a naeya or a greedy looter/hungry thief. Keremar has a spin stun proc.
