Review

The Fire Leviathan is Mimiron's giant war machine and the first boss of Ulduar. The only battle in the range entirely based on vehicles: the raid is divided into siege engines, destroyers and choppers (vehicles scale based on the ilvl of the driver’s gear). The boss chooses a victim every ~30 seconds by Pursuit - they kite her while the destroyers throw pyrite, and the passengers thrown on their back destroy the turrets, stunning the boss. Hardmode - leave 1-4 guardian towers untouched: each adds HP and an ability to the boss, and items 13-27 ilvl higher to the loot.

General tips
  • Normal starts at Brann Bronzebeard, hard mode at Loremaster Norgannon: he activates all 4 towers; Before the fight, take down as much as you DO NOT want to keep.
  • The technique scales based on the ilvl of the driver’s equipment—put the best-dressed gear in the destroyers: pyrite is the main DPS of the battle.
  • The Victim of the Pursuit kites the boss in a circle, the others follow: the kiter who runs away alone prolongs the battle and dies on the Battering Ram.
  • Keep a supply of blue pyrite on the ground - siege engine turrets shoot down flying barrels, destroyer mechanics pick them up with a grappling hook.
  • After each System Shutdown, the boss loses all stacks of speed - this is both the burst window (+50% damage) and a break for the kite.

Combat phases

Phase 1 Main loop - carousel The whole fight

Every ~31 sec the boss hangsStalking at a random siege engine or destroyer and chases it for 35 seconds, graduallygaining stacks of speed (+5% per stack).

Phase 2 System shutdown - burst window Broken 2 (10) / 4 (25) turrets on the boss's back

The Destroyers catapult passengers onto the back of the Leviathan - there are 4 defense turrets. When the required number of turrets are destroyed, a Circular Overload is triggered: the boss stands up for 20 seconds, receives +50% damage and loses all speed stacks. All the DPS goes to the boss, the choppers pick up the passengers who have jumped off and treat them with first aid kits.

  • Passenger ejection
  • Destroying turrets
  • 20 sec stun and +50% damage
  • Speed ​​Stack Reset
Phase 3 Hardmode - Guardian Towers Start the battle through Loremaster Norgannon with 1-4 living towers

Each untouched tower strengthens the boss with the ability of its guardian and adds HP: Tower of Storms -Thorim's Hammer (lightning pillars), Tower of Flame -Mimiron's Infernal (a fiery ray that scorches the ground), Tower of Ice -Hodir's Fury (ice rays that one-shot vehicles), Tower of Life -Freya's amulet (nature explosions + guards). Loot scales with the number of towers up to ilvl 252 for 4 towers (Orbit-uary achievement).

Abilities

Stalking
Raid damage F.1
Every ~31 seconds the boss resets aggro and chases a random siege machine or destroyer for 35 seconds.
Action: The victim announces himself by voice and kites around the perimeter through the resin; the siege engine is saved by a Steam Rush, the turret by a Shield Generator. Don't kite through the raid.
Gaining speed
Other F.1
Stacking buff: +5% movement speed per stack. The longer the boss goes without System Shutdown, the faster he catches up with the kiters.
Action: Chopper resin slows down the boss; A complete reset of stacks can only be done by shutting down the system. Don't delay with turrets.
Battering ram
Tank F.1
On a caught target: damage, knockback and debuff +50% of damage received for 20 seconds.
Action: Don't let the boss catch up with you - ramming a car with pyrite stacks actually turns it off from the battle.
Fire Breath
Raid damage F.1
Every ~20 sec: channel for 10 seconds, 3000 fire damage per second to all vehicles around the boss.
Action: Kicks the siege engine with Electroshock - assign a duty officer. The radius of the Electroshock is smaller than the radius of breathing: the driver must be close.
Barrage arrows
Raid damage F.1
Every ~5 sec: a volley of rockets into the air, falling on random vehicles for 3770–4230 damage.
Action: Siege engine turrets and destroyer mechanics shoot down missiles with Anti-Aircraft missiles, at the same time shooting flying pyrite barrels.
System shutdown
Other F.2
There are 4 defense turrets on the boss's back. Each destroyed one overloads the circuit; after 2 (10) / 4 (25) broken ones, system shutdown is triggered: the boss is stunned for 20 seconds, receives +50% damage, speed stacks are reset.
Action: Destroyers throw passengers with a catapult (range DPS only - on their backs they hit turrets with their abilities), choppers pick them up after the stun and treat them with first aid kits. Burn all CDs in a 20 second window.
Thorim's Hammer
Raid damage F.3 HC
Hardmode, Tower of Storms: every ~60 sec, columns of lightning strike from the sky for 13,500–16,500 area damage.
Action: You see the marker beam - turn the rudders to the side. The most harmless of the four towers is left first.
Mimiron's Infernal
Raid damage F.3 HC
Hardmode, Tower of Flame: Every ~42 sec a fiery beam creeps across the hall, dealing 13,500–16,500 fire damage and leaving burning streaks on the ground.
Action: Do not cross burnt strips - they narrow the space for the kite; plan your route in advance.
Hodir's Fury
Raid damage F.3 HC
Hardmode, Tower of Ice: every ~20 sec, ice beams hit for 135,000–165,000 ice damage, freezing vehicles - a virtual one-shot of any vehicle.
Action: The most dangerous tower: the beams are aimed slowly - constant movement of all equipment, no parking. Demolish it first if you are not going to 4 towers.
Freya's amulet
Raid damage F.3 HC
Hardmode, Tower of Life: every ~30 sec an explosion of nature for 13,500–16,500 damage and summons guards of nature to attack vehicles.
Action: The guards are quickly demolished by turrets and mortars - do not let them be surrounded by destroyers.

Positioning

Classes are not important here - seats are important. 10: 2 siege engines, 2 destroyers, 2 choppers (each driver and passenger); 25 - 5 of each type. The battle takes place in a circle of a giant hall: the boss is chasing the victim of the Pursuit, all other equipment travels in a parallel course, without stretching.

🛡 Tank
The role of “tanks” is the drivers of siege engines: stay close to the boss for the sake of the Fire Breath kick with Electroshock, save the Steam Rush for your Pursuit. Ramming the boss into the side - bonus damage when it's safe.
✨ Healer
The role of the “heels” is choppers: tar under the boss’s feet (and igniting the tar for damage), first aid kits for passengers who jumped off the back, picking them up and delivering them back to the destroyers.
⚔DD
The main DPS is destroyers: hold full stacks of blue pyrite (Barrel Throw), throw boulders from a distance, catapult a passenger onto the boss’s back when called. A mechanic passenger drags barrels of pyrite to the driver with a hook and shoots down the missiles.

Role Tips

🛡 Tips for the tank
  • Electric shock is the only kick in battle: missedFire Breath - this is 30k total damage to everyone around the boss.
  • Under yourBy persecution do not run away from the raid - circle around the perimeter through fresh resin.
  • The turret shield generator is a personal save for the chase, don’t waste it on passive damage.
  • In hardmode with Hodir, never stand still.
✨ Tips for healer
  • Resin is the main control of the battle: a fresh puddle in front of the boss’s nose for every chase.
  • Set fire to tar (turret shot at a puddle) - a decent pillbox on the boss, coordinate.
  • The passenger after jumping from the back is a priority: without a first aid kit, he will die from fall damage and rockets.
  • The chopper's speed allows you to be on time everywhere - you are the logistics of the raid.
⚔ DD Tips
  • Pyrite stacks should not fall to zero - this is a direct loss of DPS: request barrels from the mechanic in advance.
  • Only ranged DPS fly onto the boss’s back: the miles on the turrets do not have normal buttons.
  • On the back, focus everyone on one turret at a time - faster stun, more burst windows.
  • Saving speed (Acceleration) eats pyrite - only if there is a real threat of ramming.
