Background:
The Molten Destroyer is the toughest of the normal mobs you will fight in the Molten Core, though not the deadliest. When we first came across one of these mobs we thought it was a random named. They are typically lvl 63 which makes an already tough mob tougher. They take quite a while to take down. As you head deeper into the zone, Molten Giants will be more often replaced by Molten Destroyers. They share many of the same traits as a Molten Giant and like his smaller brother is not known to respawn while raiding.

Attacks:
He has a single target attack and attacks quickly. He also has a stomp which is an AE knockdown and stun. This makes getting initial agro fairly difficult and causes a lot of damage to rogues and other people in range.

Strategy:
As you get further into the zone you will come across Molten Giant and Molten Destroyer pairs. We will pull the Giant close to the raid and put the Destroyer farther away. It typically takes three healers to keep a tank up for the duration. However, to be safe, we split up the healers so that the off tank doesn't go down. Once the Giant dies we use ranged attacks to kill the Destroyer.

Farther in you will get Molten Destroyer pairs. In this case we specifically split up the healers between the tanks and execute much like a Molten Destroyer and Molten Giant pull. Kill one, then kill the next. The fight just tends to be much longer. Luckily, the agro seems to be less squirrelly than on a Molten Giant.
