The Seven

Overview

Centuries ago, the sorcerer Thaurissan and seven of his most powerful Dark Iron allies accidentally summoned Ragnaros into Azeroth, dooming their whole clan to enslavement. The Seven died during the ritual, but their spirits still haunt the Depths, cursed to serve their elemental master and the Dark Iron ruler.

Strategy

Speak to Doom'rel to start the fight. The Seven come one at a time, at fixed intervals: the next one attacks even if the previous one is not yet defeated, so strike fast. They are immune to curses. Hate'rel, for example, casts Shadow Bolt and Mana Burn, and surrounds himself with a Shadow Shield. Once the Seven are defeated, a chest appears and the door opens.
