Valithria Dreamwalker, a captured green dragon, is the first boss of the Frostwing Halls wing of the Icecrown Citadel raid. The fight ends when the raid has succeeded in healing Valithria up to 100%, while adds spawn in decreasing intervals. The fight is a chaotic battle for survival. The loss of a tank or a healer could easily result in a wipe. This boss is available since February 2, 2010 on US servers and February 3 on EU servers.
