The other day, me and some other people did a semi-clear of Plane of Fear for a palading alt's epic turn in. While we were there, we decided to clear the two golems that were up.
When we killed the second golem, Dread, there was an interesting mob up at his temple once he was dead. Had the same model as the scarelings and other imps, and it's name was simply "Test". Mob did not agro, did not respond to hails, and I don't think it could be attacked.
Anyone have any idea what might be up? Change to Plane of Fear in the works, perhaps, or is it a random bug that can happen anywhere?
