Game Mechanics: Proximity Aggro

[Furniture]

By the way I don't remember there being certain exceptions for different mobs.

I just recall that back in the day mobs will add you to the hate list once you get in aggro range and come back for you if whoever pulled the mob zoned out or something. As for undead I also recall undead mobs would also add you to the hate list but no matter what they would always go for whoever was closest, similar to root aggro.
