Is there's a way to make a creature that has los attributes (like gameobjects you can stand on)

Like they did in cataclysm for the quertermaster. I’m trying to think if it’s possible to create creatures that will have LOS, meaning you can’t go through him - you can climb ontop of them, Yet it is a creature, not a gobject.

  1. what build of wow? 2. i think it’s a feature in cata client. correct me if i am wrong tho

It’s a bit late but maybe someone is still wondering: They most likely spawned an (invisible) Gameobject on top of the NPC, I don’t think the NPC’s really had collision.
