Within the third Wing of Heroic Molten Core you will encounter Baron Geddon and Golemagg.

Defeating each of the bosses awards you with 100 Valor. Valor is used for upgrading an army slot to Diamond (+4 levels). Defeat both bosses to earn yourself a Golden Molten Giant Skin. For repeat clears in the subsequent cycles, one reward per cycle, you will get 2000 Arc Energy instead of the golden skin.

Minis in Heroic Baron Geddon’s Army

  • Dark Iron Miner - Dwarven Ambition
  • Drake - Engulfing Flames
  • Gargoyle - Aerial Superiority
  • Living Bomb - Burden of Fate
  • Vultures - Migration

Baron Geddon can only deploy regular minis at the Towers. If it does not control any Towers, it can only cycle between Dark Iron Miner and Living Bomb. The Heroic version has such a small deck that it cannot be completely locked out of playing minis even if it controls no deploy zones.

The Boss and Other Minis

Baron Geddon

  • 11,500 health
  • Unstoppable, Special Resistant (75% Elemental damage reduction)
  • Melee Sweep: 165 Elemental damage, applies Burn, 2.7 seconds attack speed, 4.5 range, 9 radius

Map Mechanics

The floor is lava. The lava floor deals 80 Elemental damage every 0.5 seconds to ground minis that stand on it. It also instantly pops Whelp Eggs. The lava does not hurt minis with specific immunity to it, bosses (like Geddon itself), and Ragnaros.

Geddon does not mind the lava and happily walks around the map clockwise. His path goes by all four Towers, which he will retake as he passes.

Baron Geddon summons Fire Elementals. The first one spawns after 4-7 seconds, and new ones spawn every 12-15 seconds from there. These Fire Elementals have Fan the Flames talent and are immune to the lava floor.

Phase 2 begins at 70% health

  • Geddon cleanses itself of Burn and Poison
  • Geddon gains a 90% damage shield for 5 seconds
  • Geddon deals lethal damage to all enemy minis in a radius of 10
  • Geddon summons a Tornado
  • Geddon spawns two Fire Elementals at every corner of the map. These Fire Elementals have Fan the Flames talent and are immune to the lava floor.

Phase 3 begins at 40% health

  • Phase 3 transition is identical to the phase 2 transition: there are now two Tornadoes on the map
  • Additionally, Geddon gains +0.05 gold per second in additional income

Tornado spawns at the top of the map, and starts moving counterclockwise with a movement speed of 1.5. Geddon’s minis are immune to Tornadoes, but any of your buildings or minis that touch one take 80 Elemental damage every 0.5 seconds. It is possible to spawn both Tornadoes on top of each other if you phase Geddon at the right time, but this is generally not necessary.
