Purges 1 beneficial magic effect from an enemy. If an effect is devoured, the Felhunter will be healed for X.
A felhunterpower that removes 1 harmful Magic effect from the felhunter's warlock master or one of his/her allies or removes 1 beneficial Magic effect from an enemy. If Devour Magic successfully removes a Magic effect it will heal the Felhunter.
Devour Magic counts as a dispel and can fail due to abilities that reduce the chance of spells being dispelled, such as Contagion.
This instant-cast ability has a 8-second cooldown.
Even if this spell is on auto-cast, the Felhunter will NOT automatically use it on the Warlock that controls it. You must target yourself, then manually use the spell.
Avoid setting Devour Magic to auto-cast in PvP situations. Since the Felhunter can cast Devour Magic on the Warlock while he or she is incapacitated, the Warlock is able to break out of fears, silences, sheeps, slows, and many roots or stuns without popping a trinket. See Felhunter Tips for more details.

/Patch 4.0.1 (12-Oct-2010): Devour Magic no longer removes a harmful spell from a friendly target. (Not entirely certain in which patch this change was actually implemented. This patch is an estimation from what info I could find.)
