The first raid tier in Wrath of the Lich King was tier 7, dropping from the bosses in Naxxramas. Wrath of the Lich King introduced two versions of the same raid (10 and 25 man) and the tier sets that dropped were different colours. For this section I am only showing the 25 man versions, mainly because I think they are better and brighter looking.
As per usual, matching belt and boots are below the pictures! :D
