The chilling final wing of Naxxramas has been unlocked and awaits you at the pinnacle of the necropolis. Frostwyrm Lair is now open and it seems a certain Archlich has got a bone to pick with you.
Frostwyrm Lair is the final wing of Naxxramas—home to Kel’Thuzad and his powerful undead frostwyrm, Sapphiron. Just like the other wings, victory over these heat-deprived hooligans will reward you with all-new Hearthstone cards.
Kel’Thuzad is the final boss of Naxxramas, and he eagerly awaits the opportunity to strike down all interlopers who have dared to step into his precious floating necropolis. If you thought the other bosses of Naxxramas didn’t play fair, remember—you’re in his lair now! A victory over Kel’Thuzad will reward you with two Shade of Naxxramas cards to add to your collection.
Defeating all of the bosses within Frostwyrm Lair will add the Legendary Kel’Thuzad card to your collection.
Frostwyrm Lair also features the final Class Challenge that will become available to those who have defeated the bosses on Normal Mode. Overcome this Challenge and you’ll be rewarded with a shiny new class-specific card to expand your repertoire.
For those of you seeking out a serious challenge, Heroic Frostwyrm Lair becomes available after you’ve defeated all of the bosses on Normal Mode. Heroic Mode bosses are significantly more difficult than their normal versions, and the Heroic Frostwyrm Lair bosses will freeze all that oppose them in their tracks!
