Anti-Magic Zone is a death knight honor talent, available at rank 37. It allows the death knight to themselves and their allies from harmful magic. A large, stationary bubble will form around the death knight with a radius of about 8 yards, surrounding them and all of their allies. Spell damage done to all party/raid members inside of the zone is reduced by 60%, lasting 10 seconds.
Notes
Anti-Magic Zone is extremely useful for tanks in magic-heavy fights, although not for arena. It is useful in obvious situations such as against a free-casting mage or warlock, but it should be noted that it is helpful against less obvious classes, such as rogues, where it will absorb 40% of Poison procs and Envenoms.
Chaining this back-to-back with [Anti-Magic Shell] makes the death knight a very frightening opponent for any spell caster.
