There is a lvl 118 mob with the name "a wandering gargoyle" that I have encountered in back to back Anguish runs on Drinal. I was able to kill it with my mains, it doesn't appear to be on any faction and it dropped nothing. Seems to hit for around 55k. It appears on track when you first zone in, and has a separate respawn timer from the zone trash. The first encounter he jumped me as I was looking for him with track and I couldn't determine where he spawned exactly aside from spawning near the pillar on your right before you enter the palace. The second time I was able to /tar him near the pillar before getting in aggro range, and use my bard's cast vision song to find him. He is directly inside the right pillar. If this mob is intended to spawn inside a lvl 70 raid zone, I would love to what for/why.
