Ice Barrier is a level 11 Frost mage ability. It is an important defensive cooldown, shielding the caster for up to 60 seconds, absorbing damage similarly to a priest's [Power Word: Shield]. The shield absorbs physical, magical, and most environmental damage (fall damage is not absorbed). Damage from DoTs such as poison is also absorbed.
Patch 2.3.0 (2007-11-13): Ice Barrier will gain an additional benefit from frost spell damage gear, however the base amount of damage absorbed for ranks 5 and 6 has been lowered.
Patch 2.1.0 (2007-05-22): Ice Barrier Rank 6 was added.
Patch 1.11.0 (2006-06-19): Ice Barrier received an overhaul. The spell was changed to stack with [Power Word: Shield] (which previously overwrote it), had its cooldown reduced from 2 minutes to 30 seconds, gained the benefit of frost spell damage, and was prioritized to absorb damage before [Mana Shield], thus saving mana when using both shields.
Patch 0.9 (2004-08-17): Training costs added to ranks.
