The Molten Core is the new last boss encountered in
Molten Core. This is an optional boss that can only be fought if the rest of the raid has been cleared on Heat 3 difficulty. This boss should be fought by first splitting into 2 groups, this not only lowers the downtime from moving out of
Meteors, but it also allows the raid to grab the
Primal Flame Elementals away from the friendly
Hydraxian Firefighter NPCs with more quickly.
You need two tanks, one to tank
The Molten Core, and another to taunt the
Primal Flame Elementals when the former summons them with
Conjure Flame. These need to be two separate tanks because
The Molten Core applies a stacking debuff (
Melt Armor) on whoever is tanking it, increasing their physical damage taken. This isn't an issue for tanking the main boss itself since its main hits are all fire magic damage, on the other hand, the
Primal Flame Elementals do physical damage.
