Anti-Magic Shell

Anti-Magic Shell is a Death knight ability that absorbs 75% of the damage of offensive spells for 5 seconds. The caster is also immune to harmful magic effects for the duration of the shell. It does not, however, remove existing magic effects.

Improvements

 * Magic Suppression increases spell damage absorbed by 8/16/25%, and causes damage absorbed to energize the Death Knight with runic power.

Background
Anti-Magic Shell was originally an ability available to Banshee units in Warcraft III. It has also appeared in World of Warcraft, where it was used by the Shadowfang Moonwalkers in Shadowfang Keep (as Anti-Magic Shield), and in Burning Crusade, where it is used by the Banshees in the Battle for Mount Hyjal raid instance.
