How the run goes

The titan city in the Storm Peaks: fourteen bosses over four areas. The Siege of Ulduar starts with vehicles against the Flame Leviathan; the Antechamber holds Kologarn, Auriaya and the Assembly of Iron; the Keepers of Ulduar (Hodir, Thorim, Freya and Mimiron) each guard their own wing; and the Descent into Madness leads past General Vezax to Yogg-Saron. Algalon the Observer waits in the Celestial Planetarium for raids that unlock him.

Group: Ten or twenty-five players: two or three tanks, healers who can move a lot, and damage dealers ready for vehicle fights, kiting and Yogg-Saron's sanity management.

    A vehicle fight. The raid drives demolishers (catapults that can throw players), siege engines (shields and rams) and choppers (tar and speed) against a giant titan war machine. The Leviathan Pursues one vehicle at a time, sprays Flame Vents and rams with Battering Ram; demolishers fling players up onto it to destroy its turrets, which overloads its circuits and stuns it.

    Tanks
    Siege engines shield the raid's vehicles and ram the Leviathan; when it pursues your vehicle, drive away and keep it chasing you.
    Healers
    Repair and refuel vehicles at the pyrite and repair spots; keep your vehicle out of Flame Vents.
    Damage dealers
    Demolishers keep up pyrite and hurl players onto the Leviathan to kill the turrets; choppers lay tar to slow it. Burn it during the overload stun.

    • Flame JetsStomps the ground causing geysers of flame to errupt under all enemies. These geysers deal 5655 to 6345 Fire damage, knocking the targets into the air and interrupting any spells being cast for 6 sec. In addition, the targets take 1000 Fire damage per second for 6 sec.
    • ScorchFires a jet of flame, burning all enemies in front of the caster within 30 yards, dealing 2357 to 2643 Fire damage every half-second for 3 sec. Additionally, the ground is scorched by this effect causing it to catch on fire, dealing 1885 to 2115 Fire damage every second to all enemies within 13 yards. Iron Constructs within this radius will begin to heat up, eventually becoming molten.
    • Activate ConstructFires a bolt of magma at a random deactivated Iron Construct, activating it and causing it to defend the caster.
    • BerserkIncreases the caster's attack and movement speeds by 150% and all damage it deals by 500% for 5 min. Also grants immunity to Taunt effects.
    • Slag PotCharges and grabs a random enemy target, tossing them into the caster's slag pot. The target is unable to attack the caster and takes 4500 Fire damage every second for 10 sec. If the target survives, they are imbued with the magical slag, increasing their haste by 100% for 10 sec.

    A fire construct who activates Iron Constructs during the fight; each living construct gives him Strength of the Creator. His Scorch heats the ground, and a construct dragged through it becomes Molten; a molten construct dropped into the water becomes Brittle and shatters under a hard hit. He also grabs a player into a Slag Pot and uses Flame Jets.

    Tanks
    Main tank holds Ignis away from the water; an off-tank drags each construct into Scorch, then into the water, so the raid can shatter it.
    Healers
    Heal the Slag Pot victim through the burn, and stop casting when Flame Jets is about to land (it interrupts).
    Damage dealers
    Shatter brittle constructs with big hits as soon as they come out of the water; otherwise keep damage on Ignis.

    A proto-drake held in the air by Expedition harpoons. While she flies, Dark Rune Watchers, Sentinels and Guardians climb out of the caves; fire the harpoons to bring her down. On the ground she breathes fire, fuses the tank's armour and buffets; Devouring Flame burns the ground. At half health she stays grounded for good.

    1. Air: kill the Dark Rune adds and fire the harpoons when they're ready to pull her down.
    2. Grounded briefly: burn her; move away when she breathes as she takes off.
    3. Permanently grounded (from half health): tank swaps on Fuse Armor; avoid Devouring Flame.

    A giant construct. Searing Light and Gravity Bomb mark players, who run out of the raid before they go off; Tympanic Tantrum hits the whole raid. At three points his heart is exposed and Scrapbots, Boombots and Pummellers pour out of the scrap piles.

    1. Normal: tank him; marked players run away from the raid.
    2. Heart phase: burn the exposed heart (destroying it makes him harder and better rewarded) and kill the adds coming from the corners.
    Tanks
    Hold XT-002 in the middle; off-tanks pick up the Pummellers in the heart phases.
    Healers
    Heal the raid through Tympanic Tantrum, and the marked players as they run out.

NPC helpers frozen in ice around the room (mages, druids, priests and shamans) give the raid fire, starlight and storm buffs once freed.

Finally Yogg-Saron: Lunatic Gaze drains sanity from those who look at him, Shadow Beacon, Deafening Roar and Immortal Guardians. Every player has Sanity; at zero, they're mind-controlled.

    1. Sara: kill Guardians of Yogg-Saron near her, avoid the clouds that summon more.
    2. Tentacles and brain: kill the tentacles; a team enters the brain through portals, kills the illusions and damages the brain.
