The Blast Furnace

Your character vs. The Blast FurnaceCalculate DPS

Official Overview (Blizzard)

The objective of this encounter is to destroy the Foundry's massive furnace. Players must first disable the Blast Furnace's Heat Regulators, which will release the Heart of the Mountain, a blazing fire Fury that powers the furnace. Primal Elementalists then join the fight and channel beams to control the raging Fury. Once the Primal Elementalists have fallen, the Heart of the Mountain is unleashed and must be dealt with directly.

Tanks
