Greyheart Nether-Mage

Greyheart Nether-Mages are Broken located in Serpentshrine Cavern.

Tactics
Nether-Mages can spawn in three types: fire, frost, or arcane. The type of mage may be determined by looking at their self-buff; each uses a damage buff of its particular school, as well as two different AOEs of that school. For example a fire mage has a self-cast buff that grants +350 fire spell power. These buffs may be stolen to boost your mages' damage and reduce the damage dealt by the mob. Furthermore, all Nether-Mages can use Blink to move to a random player, although it does not appear to be an aggro drop. They are vulnerable to sheeping and fear. They are immune to Hammer of Justice and Curse of Tongues.

With the exception of the channeled Rain of Fire none of their abilities have cast times. However, they cannot cast while feared, and can be chain feared rather than tanked to prevent casting.

They are also immune to Sap and Mind Control.

Abilities

 * Fire Mage
 * Rain of Fire - 2300 fire damage every 3 seconds to all in radius.
 * Fireball Volley


 * Frost Mage
 * Cone of Cold
 * Frostbolt Volley


 * Arcane Mage
 * Arcane Lightning (point blank chain lightning-like effect)

The arcane mages tend to be the most dangerous. It is often wise to keep them mages CC'd until everything else is cleared.
