Icecrown Citadel is Open completely

Normal mode of Icecrown Citadel is open as a blue post on the official World of Warcraft forum. It posted by Lead Encounter Designer Daelo at 02:20:07 AM PST in February 19, 2010.
Blizzard has decided to remove the limited attempts in normal mode against Professor Putricide, Blood-Queen Lana’thel, Sindragosa, and the Lich King in Icecrown Citadel. However, the limited attempts will remain in place in heroic mode.

After each region’s maintenance this week, raids will no longer lose attempts on wipes in Normal mode for Professor Putricide, Blood-Queen Lana’thel, Sindragosa, and the Lich King. There will still be limited attempts in Heroic mode.

We will continue to monitor developments in Icecrown Citadel in the future, especially since the Heroic difficulty has been unlocked by a significant number of raids.

Don’t miss the follow up by Daelo as well as!

Follow up time!

Q: If you extend your raid lockout this week, will you still lose attempts on Normal after the hotfix?
A: No.

Q: If you run completely out of attempts on Heroic, will the wing bosses and Lich King no longer respawn, even if the difficulty is switched to Normal?
A: YES. So leave an attempt left if you wish to kill them on Normal. I’ll try and correct this in a future update.

Q: Why is the counter still visible in Normal?
A: The hotfix being applied just stops the counter decrementing, and nothing more.
