Blizzard has shared some final fixes for Icecrown Citadel, explaining the attempt counter for final wing bosses, as well as a fix for Lord Marrowgar. Icecrown Citadel launches later today, October 12 at 3:00 PM PDT!
We have a couple of notes for you.
Icecrown Citadel has an attempts counter. When your Heroic attempts counter hits zero, both the Heroic and Normal difficulty end-wing bosses will no longer spawn for the rest of the current week.
