This WoW set features the full Lightbringer transmog, which is the paladin tier 6 raid set. Lightbringer is obtained by looting armor tokens from various Burning Crusade bosses. These tokens can be traded for set pieces via Shattrath City tier vendors. Note that, originally the tier 6 paladin set was only a six piece set, but later changed to include non-matching feet, wrist, and belt, as they still match other Sunwell Plateau raid gear. Matching non-set belt and feet are provided next to the sets below.
How to Get Paladin Tier 6? By slaying Hyjal Summit, Black Temple and Sunwell Plateau bosses.
Are There Multiple Tier 6 Transmogs For My Class? No, some classes do have multiple tier 6 sets (depending on their class trees), but every tier set variation features the same exact transmog look. For example, the paladin has a different set for retribution, holy, and protection, but all three sets share the same exact model and color variation. (Hunter, Mage, Rogue, and Warlock feature only one tier 6 set)
How Many Set Pieces?  Helmet, Shoulders, Chest, Bracer, Hands, Belt, Pants, and Feet.
