Within the second Wing of Heroic Molten Core you will encounter Garr and Gehennas & Shazzrah.

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 Flamewaker Skin. For repeat clears in the subsequent cycles, one reward per cycle, you will get a Mythic Tome instead of the golden skin.

The Boss and Other Minis

Garr

  • 15,000 health
  • Unstoppable, Armored, gains Resistant in phase 3
  • Melee: 260 Physical damage, 2.0 seconds attack speed, 10 range
  • Anti-Magic pulse: 4.0 seconds cooldown, 12 radius, removes Bloodlust and Stealth from enemy minis; removes Frost, Poison, Burn, and Living Bomb from friendly minis

Firesworn

  • 4000 health
  • Armored
  • Unarmed hit: 140 Siege damage, 2.0 seconds attack speed, melee range, only attacks buildings and Ragnaros
  • If a Firesworn destroys a building, it deals 225 Physical damage to all nearby enemies in a radius of 5
  • When a Firesworn dies, it explodes for 400 Elemental damage on a radius of 6 and spawns 3 Firesworn Rubble
  • Anti-Magic pulse: 4.0 seconds cooldown, 9 radius, removes Bloodlust and Stealth from enemy minis; removes Frost, Poison, Burn, and Living Bomb from friendly minis

Firesworn Rubble

  • 750 health
  • Armored, Fast
  • Unarmed hit: 70 Siege damage, 2.0 seconds attack speed, melee range, only attacks buildings and Ragnaros
  • If a Firesworn Rubble destroys a building, it deals 225 Physical damage to all nearby enemies in a radius of 5

Map Mechanics

Whenever you capture a Tower, Garr spawns two Firesworn at his side. The Firesworn start making their way down towards your base, one on each lane. Trading Towers back and forth can spawn a lot of Firesworn.

Phase 2 begins at 70% health

  • Garr cleanses itself of long Burn and Poison
  • Multiquake deals lethal damage to all enemy minis within a radius of 15 from Garr
  • Multiquake also deals 16 Siege damage to all enemies within a radius of 7 around each Tower every 0.2 seconds for 10 seconds, including to any enemy-held Towers themselves. Towers take 1600 damage overall from Multiquake, so they survive it if they are higher level than Garr.
  • Garr casts Earthquake: targets the closest enemy ground mini or building within a range from 9 to 100, and deals 5 Siege damage every 0.25 seconds on a radius of 7 until the main target dies. Garr will subsequently cast another Earthquake after 12 seconds.
  • Unlike many other bosses, Garr does not gain a damage shield at phase transitions

Phase 3 begins at 40% health

  • Garr cleanses itself of long Burn and Poison
  • Garr gains Resistant
  • There is a permanent Earthquake effect on your Barracks: 40 dps until Garr dies or your Barracks die.
  • Final quake deals 30 Physical damage every 0.2 seconds (150 dps) on a radius of 7 around the quake in front of Garr - this is Garr’s only attack ability in the last phase
  • Unlike many other bosses, Garr does not gain a damage shield at phase transitions

Heroic Gehennas & Shazzrah is not yet available in the game. The information below is based on datamining and subject to change. We will update the guide and add builds soon after the content is available.

The Boss and Other Minis

Gehennas (red boss)

  • 10,000 health
  • Unstoppable
  • Shadow Bolt: 280 Elemental damage, 1.8 seconds attack speed, 13 range, targets ground minis only (but hits both)
  • Rain of Fire: 28 Elemental damage every 0.25 seconds for 8 seconds (896 damage overall), 8.0 seconds cooldown, 8.5 range, 6 radius, targets flying minis only (but hits both), highest priority ability
  • Spawn Flamewaker Elite: When Gehennas reaches the left or right end of his patrol path, he spawns a Flamewaker Elite there

Shazzrah (blue boss)

  • 12,000 health
  • Unstoppable
  • Arcane Missiles: 75 Elemental damage per second for 5 seconds (425 damage overall), 13 range, targets flying minis only (but hits both)
  • Arcane Explosion: 260 Elemental damage, 1.8 seconds attack speed, 10 range, 11 radius, targets ground minis only (but hits both), highest priority ability
  • Counterspell: Prevents any spells from being cast while alive
  • Blink: Teleports to the top of the map at 65% and remains there for the rest of the encounter

Flamewaker Elite

  • 1500 health
  • Lava Wave: 10-second channel to summon a Lava Wave that destroys minis and buildings on its path and deals 15% damage to your Barracks

Map Mechanics

Do not bring any spells because Shazzrah will counter them all as long as it is alive.

When Gehennas reaches the left or right end of his patrol path, he spawns a Flamewaker Elite there. The Flamewaker Elite begins a 10-second cast to summon a Lava Wave. If the Flamewaker Elite is not killed before this cast ends, a Lava Wave will spawn that destroys minis and buildings on its path and deals 15% damage to your Barracks.

Gehennas uses its area-of-effect ability only when it targets a flying mini. Shazzrah uses its area-of-effect ability only when it targets a ground mini. The area-of-effect abilities have a higher priority, but are not used if the current target is still alive.

Gehennas becomes Enraged at 65% health:

  • Destroys all enemy minis on a radius of 8
  • +0.05 gold per second
  • +75% movement speed
  • +25% damage

Shazzrah blinks at 65% health:

  • +0.05 gold per second
  • Teleports to the top of the map and remains there for the rest of the encounter
