You might think to look at this screenshot that you were looking at a simple, everyday, giant skeleton of the sort you might find anywhere in a MMO.
Here it stands in its natural habitat, on eternal watch, waiting for an adventurer to come past and pull it to its inevitable death animation.
But there is something different about this particular type of mob in WoW. It’s a new breed.
Placed in Icecrown, one of the end zones in Wrath where it is assumed that the player will have a flying mount, this mob is designed to be flown over rather than killed.
It’s true. There is no quest in the game that requires anyone to kill one of these giant skeletons, yet they are common mobs in Icecrown. They patrol battlements. They stand on guard at strategic locations. They look tough and they are (relatively) tough, being elites. Not only is there no quest for them, but the drop tables don’t attract people, they aren’t part of anyone’s optimal xp gathering schemes, they don’t give rep. There isn’t even any xp for them (that’s quite damning in a MMO!)
The very first comment in the Bone Sentinel entry in wowhead says, forlornly:
I killed one and it didn’t drop anything and it also did not provide any experience.
Ladies and Gentlement, I present to you … the decorative mob. Be nice to it, it may be the herald of a new (aka old) immersive era of zone design, in which mobs are placed because they look right or they should logically be there, and not just to drive quests.
Joking aside, that’s quite an old school approach. Older MMOs often placed mobs without any intention that players would kill them. But it’s uncommon in WoW.
