The Frostwyrm Lair

The final challenge of Curse of Naxxramas. Only two bosses lie between you and ultimate triumph. All you need to do is defeat a giant flying undead dragon that breathes ice and eats adventurers for breakfast, and a cunning necromancer whose mastery of the dark arts has granted him immortality in undeath and who rules over Naxxramas with an iron fist. How hard could it be? Right? …right?
