flame-leviathan is the first obstacle in your way. A massive tank constructed by Mimiron as a part of V0-L7R-0N, the Flame Leviathan is in position to stop anyone from breaching the Titans first line of defense. Towering above the humanoid races of Azeroth, the Flame Leviathan must be fought using siege vehicles, with our heroes barely able to scratch the behemoth on foot.

This guide will offer a detailed, step-by-step tutorial on how to deal with Flame Leviathan’s overwhelming show of force.

Role Summaries

Abilities

This fight is done almost exclusively in vehicles, giving all players a new set of abilities to work with. There are exactly enough vehicle seats available for a 25-player raid, with 5 Demolishers, 5 Siege Engines, and 5 Choppers. Demolishers are the primary DPS dealers of the fight. Siege Engines are primarily focused on interrupting spells and kiting Flame Leviathan. Choppers primary role is to slow the boss and transport passengers between the boss and their vehicle.

Each vehicle has a passenger seat that has their own abilities, focused primarily on either damage or support. Gunners are able to ignite tar, generate shields, and gather pyrite for their drivers.

Vehicles

salvaged-siege-engine

The salvaged-siege-engine consists of two roles, the Driver and the Gunner. The Driver functions as a tank and close-range fighter, with the key role of interrupting the boss. The Gunner is a long-range fighter, shooting pyrite crates out of the sky and blasting enemies with cannonballs.

salvaged-siege-engines can also carry 2 bonus passengers.

Raid Composition & Preparation

This fight is done purely in vehicles. This means that individual roles are not used and no composition changes will impact the fight as long as your team consists of 25 players.

The vehicles are impacted by the driver and passengers’ average item level in most slots, meaning that the higher item level in each slot, the better your vehicle. To take advantage of this, simply make sure you equip the highest item level gear you have in every slot, except for your Ranged, Off-Hand, Tabard, and Shirt slots. Gear equipped in these slots will not count for the vehicle’s stats. The quality of the item also matters, with Epic items providing a significant boost over Rare items.

The item level of the driver increases the vehicle’s maximum health as well as the damage of the driver’s abilities. The item level of the passenger only increases the damage output of the passenger’s abilities. The actual stats of these items does not matter at all. The vehicle decides its stats when a player enters it, meaning if you swap gear while piloting a vehicle, nothing will change. You will have to hop out of the vehicle and back in to refresh its stats.

It is worth noting that while for most players their stats will not matter at all, players assigned to be loaded into the catapult and flung at the boss will not want to sacrifice too many stats in the hunt for item level increases, as they will be DPSing out of the vehicle.

Because of the way this scaling works, it is recommended to have your highest item level players driving Demolishers, and then Siege Engines, then passengers in Siege Engines. Your lowest item level players will typically want to be in Choppers, where the scaling will have the least impact.

Demolisher passengers should ideally be ranged DPS classes that can self-heal, such as Balance Druids and Shadow Priests. This is so that when they are on top of Flame Leviathan they can keep themselves alive and not have to leave the boss early.

Hard Mode

The optional hard mode for Flame Leviathan is activated by not destroying the four towers leading up to the boss. Each tower left standing increases the bosses health by 40%, stacking multiplicatively, almost quadrupling Flame Leviathan’s health with all towers up.

Each tower also has a unique buff that they provide the boss, impacting the fight in different ways.

• tower-of-life
  • freyas-ward
    • This ability decreases Fire Damage dealt to Flame Leviathan by 10%, as well as periodically spawning plants from the corners of the arena that will attack player vehicles.
• tower-of-flames
  • mimirons-inferno
    • This ability boosts Flame Leviathan’s Fire Damage dealt by 50%, as well as causing meteors to periodically fall from the sky in a set path.
• tower-of-frost
  • hodirs-fury
    • This ability causes white markers to follow players, occasionally stopping and calling down a frost meteor, dealing heavy damage, and freezing them until they are thawed out with an ice attack.
• tower-of-storms
  • thorims-hammer
    • This ability boosts Flame Leviathan’s Physical Damage dealt by 25%, as well as causing beams of light to appear and deal massive damage to anyone underneath them.

Every tower left standing increases the rewards. With all four towers up you will receive an item from the hard mode loot table in addition to the regular drop table.

• Golden Saronite Dragon
• Boots of Fiery Resolution
• Pendant of Fiery Havoc
• Plated Leggings of Ruination
• Shoulderpads of Dormant Energies

The Gauntlet

The boss event begins with talking to the lore-keeper-of-norgannon, activating the four Defense Towers. Players will then be able to enter vehicles, either salvaged-demolishers, salvaged-siege-engines, or salvaged-choppers. There are 5 of each kind of Vehicle. With 25 players, you have just enough for every salvaged-siege-engine and salvaged-demolisher to have both a driver and a gunner, as well as every salvaged-chopper having a driver.

The gauntlet involves fighting through the legions of Iron Dwarves, Iron Giants, Vrykuls, and various mechanical creations. None of these enemies are particularly noteworthy, except Ulduar Colossus, which cast Ground Slam. This ability should be interrupted by salvaged-siege-engines with electroshock.

During the gauntlet, there will be Liquid Pyrite tanks floating in the sky. These will need to be shot down by the vehicle gunners and loaded into the vehicles. Try to stock up on as much pyrite as possible before you reach the boss.

You will also be able to find 4 towers in this gauntlet. These are the optional hard mode, and each one destroyed makes the fight easier but also less rewarding.

Pulling The Boss

Shortly after you have killed the last group of enemies, the boss will enter its arena and the fight can be started. Outside the entrance to the boss arena, there are two repair platforms that can be used to heal your vehicle and refill pyrite if needed. Start driving into the boss to initiate the fight.

The Fight

Flame Leviathan is a simple enough fight. There is no threat table to worry about, instead Flame Leviathan will fixate on a specific player’s salvaged-demolisher or salvaged-siege-engine for 30 seconds. During this time, the boss will chase that player, almost certainly killing them if it reaches them.

To stay alive while fixated you will need to kite the boss around the arena, this is done with a combination of speed-boost/s and the slow provided by tar.

salvaged-demolishers are the primary source of damage during this fight, and will ideally want to maintain 10 stacks of Pyrite Barrel on the boss at all times. This requires the passenger to consistently grab Pyrite scattered around the arena.

salvaged-siege-engines are necessary to interrupt flame-vents using electroshock. This requires 38 Steam Pressure, so the drivers will need to keep an eye on their resources so that they have enough Steam Pressure when flame-vents is cast.

salvaged-demolishers are able to launch their passenger at the boss. Players that are on top of the boss are able to destroy the leviathan-defense-turrets, and once all turrets are destroyed the boss will be stunned for 20 seconds, and take 50% increased damage. This also removes all stacks of gathering-speed, which is necessary to be able to kite the boss.

Launched players should exclusively be ranged DPS, as melee DPS will only be able to reach one turret, while ranged DPS can reach all four. After the boss has been overloaded, players will need to jump off the boss and be ferried back to their salvaged-demolisher by a Chopper.

If you are attempting hard mode, the boss will have a few more tricks in its arsenal. Each tower provides a unique buff to the boss, alongside a 40% health buff per tower.

The tower-of-life gives the boss freyas-ward, dealing constant Nature damage to all enemies around Flame Leviathan and summoning Ward of Life and Writhing Lasher from green beams in each corner of the boss arena. The boss will also be buffed with tower-of-life, decreasing the fire damage it takes by 10%. This constant bonus damage primarily means the group will have less room for mistakes during the fight. Consider assigning a Siege Engine to each corner to deal with these adds as early as possible.

The tower-of-flames causes Meteors to fall from the sky, slowly following a set route. These are easily avoidable but will absolutely decimate anyone hit by them. Flame Leviathan will also deal 50% increased Fire damage with this tower up.

The tower-of-frost causes pale beams of light to appear, following players. The beams will stop moving on top of vehicles, calling down an icy comet on top of them and freezing them, dealing constant damage. Frozen vehicles will need to be hit with Fire damage to break the ice, freeing them.

The tower-of-storms causes pillars of light to briefly appear and after a small delay deal heavy damage to everyone caught in the beam. This also causes Flame Leviathan to deal 25% increased Physical damage.

Here are some of the main things that can typically go wrong in this fight:

• Passengers in vehicles go AFK or otherwise do not participate, leading to their drivers dealing significantly less damage.
• Chopper drivers don’t slow the boss effectively, letting it catch up to fixated players.
• salvaged-siege-engine drivers fail to manage their resources, letting the boss cast flame-vents freely.
• People generally don’t put in the effort because it is a vehicle fight.
• Adds are not dealt with appropriately, causing the raid to be overrun.
