Derived from Ice Barrier - Drysc slang;
Ice Barrier is a mage spell that shields the caster, absorbing all damage, similar to a priest's Power Word: Shield spell. The shield absorbs physical and magical damage, including damage from active DoTs. While shielded, spells will not loose casting time due to push-back interruption, however counterspell and silence effects will still pass through. The amount of damage absorbed is increased by 10% of the caster's frost spell damage. The damage shield stacks with the mage spells Mana Shield, Fire Ward and Frost Ward, and stacks with other damage shield spells such as Power Word: Shield. Ice Barrier is self-cast only.
