he dungeon is divided Tera Gold into four wings (in increasing difficulty): the Spider Wing, the Death-knight Wing, the Plague Wing, and the Abomination Wing.
Each of them holds different types of creatures including crypt-lords and crypt-fiends, death knights, abominations and risen dead, as well as your old friends the necromancers and liches.
There are 15 boss encounters and if you count the four horsemen as four different bosses you have 18 different boss mobs - more than MC and BWL combined. Kel'Thuzad can drop 16 epic quality items, eight of them are weapons. Among them is the ring piece of the Tier 3 armor sets available in the instance (Tier 3 sets contain 9 items).
