If the statue in the middle (at portal in) is facing the black tower It will spawn this named on the death of ANY mob, and no its not instant arrgo he spawns close to you tho. There is a zone wide Emote that tells you when the statue is facing a different tower. obviously there are 4 towers.
Also Peacekeepers can drop ANY loot that drops from any named inside that certain tower.
This guy cast silence so be in for some fun, he is doable just if u get unlucky and he starts chain casting silence ur screwed.
