Harbinger of Rage

Harbinger of Rage is the boss that is located in the back of Halls of Flame. This is the hardest of the first four bosses to kill, as it has the most health and takes the longest to kill.

Strategy
The Harbinger of Rage has a simple strategy, like all bosses in Halls of Flame leading to Sanoxx, but this is the hardest boss to kill of the first four, as he has the most health out of all of them.

You will want to kite the Harbinger of Flame around the giant open area in the middle of the Halls. Because this is the second longest fight in the raid, there will be a ton of adds that spawn.

It is highly recommended to burn down all of the boss's health as fast as you can, and then worry about the adds when you kill the boss.
