Flame Leviathan

Encounter Details

Basics
 HP: 62.5 million (Heroic) / 20.9 million (Normal)
  Mana: None  Enrage: Unknown
Before you can engage Flame Leviathan, you must fight through an Iron Dwarf Army that includes smaller Iron Dwarves as well as large Iron Constructs. The intended feel of this trash is that of a gauntlet.

Once you get to Flame Leviathan, you fight it in vehicles that scale with your item level.
Abilities
Battering Ram
Rams the target, dealing damage and knocking it forward. (Deals 100% weapon damage and causes the target to take 50% more damage for 10 seconds. Stacks 20 times.)
Flame Vents
Inflicts 3000 Fire damage to enemies around the caster every second for 10 sec.
Gathering Speed
This buff increases Flame Leviathan's speed by 5% per application, and stacks up to 20 for a total potential movement bonus of 100%. Overload Circuit will reset the stacks to 0.
Comments: Flame Leviathan will also switch targets every 30 seconds or so. He'll mark the targeted siege engine or demolisher and then chase that vehicle until he switches targets again. You'll want to kite him around, as if he gets into range you can take substantial amounts of damage.
Turrets
Missile Barrage
Fires a salvo of missiles into the air. These select a random nearby enemy target and slam into them, dealing 3770 to 4230 damage.
Overload Circuit
Overloads the power core of the Flame Leviathan. (Channeled)
Comments:
  • You'll need to throw players up on top of Flame Leviathan to destroy the turrets. This will help reduce damage taken and expose the power core.
  • You'll need two players for 10-player and four for 25-player to right-click on the exposed core to trigger Overload Circuit.
  • Triggering Overload Circuit will stun Flame Leviathan and cause him to take 50% additional damage for its duration.
Hard Mode
To trigger Hard Mode, speak with the Lorekeeper of Norgannon at the entrance of Ulduar. Once you've enabled Hard Mode, you'll need to leave specific towers situated around the Iron Concourse.

Note that leaving these towers up grants Flame Leviathan additional abilities, as well as increasing his health and damage for each tower left up.
