Kraator
Kraator is a rare fire elemental that can be found in Shadowmoon Valley. He is most commonly seen just south of Eclipse Point. The best place to farm while waiting for him to spawn is the Blood Elves at Eclipse Point. You won't need a macro for this mob etheir because he is really one of a kind and too big to miss.
As with every other of the rare elites, I highly recommend checking all 5 of his spawn locations every 10-15 minutes. The rare elites usually have a spawn time of an hour.
