Health:

• Normal:  5.2M (Arms 1.2M each)
• Heroic:  20.9M (Arms 5.2M each)

Abilities:

• Focused Eyebeam:  Inflicts 4163 to 4837 Nature damage to enemies within 3 yards.
• Petrifying Breath:  Inflicts 18750 to 21250 Nature damage every 1 sec and increases damage taken by 20% for 8 sec. (Brittle Skin - Increases damage taken by 20% for 8 sec.) - Only does this if no one is in melee range
• Overhead Smash:  The not so massive attack Inflicts Physical damage and decreases armor by 25% for 45 sec. 5 yd range, Next melee;  Stacks to 4, used every 10-15 seconds.
• Overhead Smash Tremor:  The massive Overhead Smash causes a tremor which Inflicts 6338 to 6662 Physical damage and interupts casting for 8 sec.
• One-Armed Overhead Smash:  Same as overhead smash but less power, used when 1 of the arms is destroyed
• Stone Shout:  Unleashes a hail of jagged rock, striking target enemy every 0 sec for 2 sec, and damaging any additional enemies within 50000 of the target.   Does about 3K damage per tick, only used if both arms are destroyed

Left Arm (our right):

• Shockwave:  The shockwave from the massive arm sweep inflicts 13875 to 16125 Nature damage.

Right Arm (our left):

• Stone Grip:  Squeezes the life out of the target, stunning it and inflicting 5363 to 5637 Physical damage every 1 sec until Kologarn's Arm sustains 480,000 damage;  Targets 1-3 people.   Less damage in 10m, and needs 150K damage.

The Fight:

Firstly, the boss is just stuck on the ground, won't move, can't get behind him, so melee will suffer from parries and such.   There must always be someone in melee range or he wipes the raid.   He does slow hits, so optimal tanks appear to be druids or DKs.

He has 2 arms as seperate entities to target and kill if you wish so.   Killing one will knock off 15% of his HP, but each arm has more HP than that.   They respawn 60 seconds later.  Also killing one will spawn 5 adds, must be tanked and they aoe us, but can be stunned.   Best done with a warrior's Shockwave.

The Left Arm will Shockwave us every 25 or so seconds.

The Right Arm will Stone Grip 1-3 non-MT raid members, and they must be healed.   Here there are 3 methods of thoughts of dealing with it:

Leave the Arm up, heal through it the rest of the fight or...

Attack the Arm to release the trapped ones, but be ready to tank/stun adds when the arm dies.

Or kill the right arm at all times, deal with adds, then kill the boss, which is what we did.

For the main boss himself, with the Crunch Armor debuff, you'd want 2 tanks trade taunting off.  Though in 10 man, it appears to apply less frequently and fails to stack often.

There's a laser beam for the raid to avoid as well.

Note for Melee:  If you're attacking arms, you may notice sometimes you can't hit him.   With auto-attacks or whatever, and you have to reposition and stuff.    What's known now is that Kologarn is one giant hit box for both him and his arms.   So what you should be doing is facing him at all times, just retarget arms when attacking those, do not turn.   You don't have to run from arm to arm, you are able to target him and any of the arms simply standing anywhere in front of him, facing the main body.

Trash Info:

Dwarf Packs (10 man):  3 mobs, a Mender, a Charger, and a Construct.   We killed the Mender cause we didn't like his name.   The charger appears to just do a weak chain lightning.   Killed him next.   Construct was just debuffing Nuitbear with a slowing thing.  

Dwarf Packs (25 man):  The packs are doubled in size (2 of each of the above), and are more lethal.  The Charger does a thunder ball that does a lot of damage to the area it hits.   The Constructs root themselves but do 100% more damage.   The tank can run out but there better not be other people in range he can smack.   The Menders are CC'able, maybe all of them all.     Adjusted tactic was to sheep the Menders, burn down the Chargers first.   Then the rest, I think menders after.

Big Construct Packs:  2 Constructs, they have flamethrowers, so don't be in front of him.  They also "throw" out runes on the ground underneath people.    Whoever stands under em turns into bombs.    Don't blow the raid up.

Big Titan Packs:    Single pulls, they have a front cone aoe shout that's physical damage, physical avoidance works.   They summon spark things that do minimal damage in 10 mans.

Achievements:

With Open Arms:  Defeat Kologarn without destroying either of his arms on Normal/Heroic Difficulty

Simple enough to try to do.   Only means we employ the tactic of screw the guy in the Stone Grip, and heal through it.    Or, hit it just enough to release him, and hope you got enough dps to finish off Kologarn before requiring you to kill the arm.    Or combine the two a bit, when arm is low, screw the guy in Stone Grip and focus on Kologarn.  Definitely see several possiblities to try.

Disarmed:  Destroy both of Kologarn's arms within 10 seconds and then defeat Kologarn on Normal/Heroic Difficulty.

There's a possible bug where if you use the arms to kill Kologarn, it will not count (they take off 15% hp each).   We did the Right Arm zerg strat til Kologarn was 40% ish, make sure Kologarn is above 30%.  Then got some dps on the Left Arm.   Went back on the right arm, while switching sometimes to keep left arm low too.   Then kill right, kill left, kill Kologarn.

If Looks Can Kill:  Defeat Kologarn without any raid member being hit by Focused Eyebeams on Normal/Heroic Difficulty.

Simple enough, don't get hit.   Nobody gets hit.

Rumble and Roll:  Defeat Kologarn with 25 Rubble creatures alive on Normal/Heroic Difficulty.

This might be deceptively tricky.  First thing is, someone OT'ing the Rubble to the side of course.   But each arm only seems to spawn 5 rubble.   So to do this, we need 5 arm deaths in the fight.   But, we killed Kologarn with only 3 arm deaths.

This could mean, we cannot dps Kologarn himself at all.   We must only deal with the arms.   And since we can't have both arms dead at the same time, it could mean we only kill 1 arm the entire fight.    So kill an arm, wait 60 sec, kill right arm again, etc.

Well but arms only take off 15% of Kologarn's HP each, so that's 5x15% = 75%.   That's still 25% of his hp we can afford to dps.   Though, that means at most 5% after each arm.   5% of hp in 60 sec.   That's nothing, there'll probably have to be forced downtime if we do this.

Perhaps just more tanks dealing with the adds without killing them be the way to go.

Hard Mode:

Hard mode here is just leaving Steelbreaker for last.

The Fight:

This will likely be the first real challenge in Ulduar.   A 3 in 1 boss, each with their own HP and abilities, and similar to Karathress fight, they gain abilties as each one dies.    Unlike Karathress, it's a brand new abiltity rather than taking one from the dead ones.    The above ability list indicates the 1st bonus as the 1st ability they get after any of the others die.   The 2nd bonus would be their 2nd ability when the 2nd dies, or in other words, when we save him for last.

I will list probably the 3 orders to kill this boss, based on achievements and hard modes.  Yes, technically more are possible, but only the last boss alive counts, so easiest route for each.

Note:  We've found that using a Pally tank to tank Steelbreaker is quite nice.   Ability to self cleanse takes the whole healer must help cleanse at the right moment or the tank dies to Fusion Punch ticks out of the equation.

Steelbreaker (Big) -> Runemaster (Medium) -> Stormcaller (Small):

This is likely the easiest route to kill.    Each one will basically just tanked away from each other while dividing the raid a bit to handle each boss.

Steelbreaker:   Due to the nature aura, everyone should be clumped up to benefit from group healing.  He can hit very hard on the tank, and CDs are recommended, thus DKs are recommended as a result.   For us, it's likely have to be Nuitbear, probably.  This guy does do a lot of nature damage, so maybe nature resist set time!  Well when hard mode arrives.   Everyone else burn him.

Stormcaller:  Probable tank should be Orky, this boss is stunnable, interruptable, cast slowable.   So with him, and maybe 1 or 2 others to help out, this guy should be locked down most of the fight.   A DK has an advantage with a "short" CD, ranged interrupt incase of rune placements.

Runemaster:  Last one left to tank is Pudo.   No real tricks at this point, except maybe the ranged can watch to see if a convenient Rune of Power spawns to sit in for extra dps.   Definitely don't take risks or go out of your way for it.

STEELBREAKER DIES!

Now the 2 other bosses gain new abilities.

Stormcaller:  Does a whirlwind lightning too now, but still stunnable / interruptable, so the guys in his corner should still keep it under lockdown.

Runemaster:  Everyone else move on to this guy.  The new trick he has is a Rune of Death, basically new variation on the Void Zone.   The problem is, it's friggin huge area, it ticks every 0.5 sec, very fast, so you're likely gonna take 6-12K damage before moving out of it.   And with lack of Unholy Aura in 3.1 for the raid, run speed enchants might be in style again.

RUNEMASTER DIES!

Stormcaller left, but no longer stunnable, so spread out to avoid chaining the lightning, and the melee run out of the whirlwinds.  The new ability he has is floating in the air, chasing some random guy down while firing off lighting aoe all around under him.    Think of it as a fancy new whirlwind to run from.   It's like Sartura in AQ40, run away!      Aggro resets so wait for a tank.

Steelbreaker (Big) -> Stormcaller (Small) -> Runemaster (Medium):

Everything's the same up to Steelbreaker dying, so take that part of the above and throw it down here, then kill Stormcaller while avoiding the Rune of Deaths and don't stop the interrupt/stuns on him.

STORMCALLER DIES!

Runemaster left, and his new trick is summoning a rune, that summons 10ish kamikaze lightning elemental adds.   They come out, chase someone down, and blow up for 15K damage (10K in normal) to everyone 30 yards around.

The adds can be slowed and should be killed before they reach anyone.   They have 12K hp in normal.    Frost Novas, earthbinds, frost traps should all be used to help with that.   They kind of have and aggro table but seems to be a bit random, perhaps global threat sometimes.

That's the new trick, bunch of bomb bots to kill/survive from.

What we did is use a Frost Mage to blizzard em down.   Definitely far easier and just one shot the thing with one.

Stormcaller (Small) -> Runemaster (Medium) -> Steelbreaker (Hard Mode):

This is the hard mode order we went with   The nature aura will be with us the whole fight, so likely keep clumped up for group healing the entire time.    If you have a Pally tanking Steelbreaker, he can self cleanse taking the Fusion Punch cleasning for the healers out of the equation for most of the fight.   If you have a DK tank, the Anti-Magic Shield can prevent a magic effect, which means the dot, from applying, so that is able to take every 3rd (?) cleanse out of the equation.

Stormcaller should go down easy, should be locked down the entire fight (since he won't go interrupt/stun immune this version).    Then kill Runemaster watch for Runes of Death.

Anyways, first ability to watch for after Stormcaller dies would be a Static Disruption, he targets a person to hit with it and the debuff spread around who he hits.   So try to stay spread out a bit if possible to avoid chaining it.

After Stormcaller dies, the 2nd ability would be Overwhelming Power, it actually buffs your tank's damage by 100% for 1 min, before you explode.   Think Vael, your tank will blow up and you have to change it.   The death will heal him for 15% so got to just have enough dps to burn though all that before all your tanks die.     Brez tanks to rotate back in if necessary.

Runemaster (Medium) -> Stormcaller (Small) -> Steelbreaker (Hard Mode):

This might be easier for some raids.   Similar to above, but kill the Runemaster to eliminate the need to run around the Death Runes.   The second guy then has to be locked down with kicks and stuns so the Lightning doesn't kill you.   Do the rest like above.

Achievements:

I Choose You, Runemaster Molgeim:  Defeat the Assembly of Iron with Runemaster Molgeim as the last member alive on Normal/Heroic Difficulty.

The medium difficulty kill

I Choose You, Stormcaller Brundir:  Defeat the Assembly of Iron with Stormcaller Brundir as the last member alive on Normal/Heroic Difficulty.

The easy mode kill

 I Choose You, Stormbreaker:  Defeat the Assembly of Iron with Steelbreaker as the last member alive on Normal/Heroic Difficulty.

The hard mode kill

But I'm on Your Side:  Defeat the Assembly of Iron while under the effect of an Iron Boot Flask on Normal/Heroic Difficulty

Personal achivement, get your boot flask from Frosthold.  Use it, don't die, kill boss.   Don't be a druid either.   Well, can use it at the last seconds of the fight to get this.

You Can't Do That While Stunned:  Defeat the Assembly of Iron without allowing Stormcaller Brundir to damage anyone with Chain Lightning or Lightning Whirl on Normal/Heroic Difficulty.

We did this while doing our Hard Mode order.   The problem is that on pull he starts shooting lightning, so you have to have ranged interrupts quickly and on the ball.    Or a rogue stealthed up near by and get that first kick off before he finishes casting.    The hard part is the pull interrupt, after that you should be able to lock it down.

Abilities:

Both Phases:

• Devouring Flame:  Spits a Lava Bomb at an enemy, inflicting 8788 to 10212 Fire damage and deals 8788 to 10212 fire damage every 1 second to anyone staying within 6 yards of the impact, lasts 25 seconds. 1.5 sec cast

Air Phase Only:

• Fireball:  Inflicts 12025 to 13975 Fire damage to an enemy.

Ground Phase Only:

• Flame Buffet:  Increases the Fire damage an enemy takes by 1500 for 1 min. Stacks up to 99 times.
• Wing Buffet:  Knocks back enemies in a radius around the caster. 1.5 sec cast
• Flame Breath:  Inflicts 17500 to 22500 Fire damage to enemies in a cone in front of the caster. 50 yd range, 2.5 sec cast

The Fight:

This is a fairly straightfoward fight.   Razorscale starts in the air, merely bombarding us with fire we avoid.  Don't stand in BLUE FIRE.

On the ground, there will be NPCs we have to defend from adds, as they will be repairing harpoon turrets.   DPS should take care of the adds as priority.   Adds will spawn from randomly appearing mole drills.

Sentinels are the vyrkuls and should be killed asap, whirlwinds are most lethal.   Watchers are the slightly smaller dwarves that shoot out chain lightning, another significnt source of damage, and should be handled next.    Guardians are the weaklings to be taken care of.

After a turret is repaired, we can click on em and fire at Razorscale, dragging her to the ground a bit.  After 4 harpoons are hit (2 in normal), she is stunned on the ground for a minute.  This is where dps goes all out on her.   The raid should be ready before the last harpoon is fired, i.e. adds mostly cleared.  After the stun wears off, she'll take off again, and we'd have to repeat this.

It should only take 2-3 ground phases before we force her to the ground.  Heroism would be best used the 2nd time she's on the ground to avoid the 3rd phase.   If she does take off, do not push her over in the air, she retains aggro, so if a tank is handling adds and not prepared to taunt, you may be fucked.

When we get her to 50% health, she'll stay on the ground, and it becomes a standard tank and spank fight.   Stay away from the front, avoid the fires, collect loot.    The Flame Buffet serves as a soft enrage so go all out.

Achievements:

A Quick Shave:  Defeat Razorscale without allowing her to fly into the air more than once on Normal/Heroic Difficulty.

This is easy with the dps.  Heroism on 2nd ground phase to better ensure it.

Iron Dwarf, Medium Rare:  Defeat 25/50 Dark Rune Guardian Dwarves with Razorscale's Flame Breath on Normal/Heroic Difficulty.

This is a progressive achievement.  Meaning we don't have to do it in one sitting.  Can slowly accumulate it over 4 years if you want.

Anyways, the goal is to get the Guardians into the Ground Phase, and have Razorscale's Flame Breath finish them off.

Because of all the damage, you might not want to bring all that spawned into Ground Phase, just what you can.   Basically means don't aoe those, drag em in front of her, ???, profit.

Anyways, repeat as many weeks as it takes til you get this.

Encounter:

Gauntlet:

The encounter is activated by talking to the npcs, though the mobs won't aggro til we move out.     Trash is easy, should be able to aoe everything down with the vehicles.   Iron Colossus' Ground Slam should be avoided or interrupted by the Seige Engines.

Towers should be destroyed along the way if Hard Mode is not the goal.   No need to clear everything though, they should not add during the boss.

If Brann is the one to activate it, the towers are automatically off, so can go straight to ez mode.

We can repair at the end of the Gauntlet, do so if not going for that achievement, and stock up on all the pyrite (ammo) you can before the last packs of the boss.

Boss:

Every vehicle must stay out of melee range of Flame Leviathan.

Seige Engines:    Flame Leviathan will immediately target somone close to him, the best option is the Seige Engine so make sure they're closest.  The goal is to kite him around, coordinate a path for the raid to follow.   The trick is that Flame Leviathan will get faster as the fight goes on, a system shutdown will reset his speed.    Also use its Electroshock to interrupt flame wave

Demolishers:  Besides being the ranged dps and tar igniter, this one can also launch passengers onto Flame Leviathan to take out its Turrets.   This might not be needed at all in easy mode.  

Coordinate a dps and a healer to be launched simultaneously to take them out.    Also coordinate  choppers to pick them up quickly and take them to safety (or demonlisher to be launched again).

Note:  A healer is not necessary on 10 man.  It appears Flame Leviathan only shoots you to death on the 25 man.

In 10 man, 2 turrets (4 in 25 man) must be destroyed before a System Shutdown occurs.   This stuns Flame Leviathan and launches the people on him off of it, parachute style.  This is when they need to be picked up, look to the sky.

Note:  Turrets instantly respawn after the Shutdown is over, so passengers can be launched yet again.   Only issue is that means Demolishers are without turret passengers to help dps or pick up pyrite.

Choppers:   They will be used to shit tar all in front of Flame Leviathan.  It'll slow him down and it can be ignited by Demolishers for more damage.    They will also be used to pick up stranded people and take em to where they need to go.

Hard Mode:

To access hard mode, along the way before Flame Leviathan, we don't destroy the towers.  Here's what each tower does:   

• Thorim's Hammer (purple, back left):  Deals Stormstrike damage to all enemies nearby. Additional damage is taken if directly under the impact location.   Flame Leviathan gains 25% more HP and does 25% more Physical damage.
• Mimiron's Inferno (red, front left):  Deals 150000 Fire damage to all nearby enemies and leaves a flaming blaze behind.  Flame Leviathan gains 25% more HP and does 50% more Fire damage.
• Hodir's Fury (blue, back right):  Deals 150000 Frost damage to all nearby enemies, entombing them in ice.  (only freeable via tar fire)  Flame Leviathan gains 25% more HP and slows vehicle movement by 20%
• Freya's Ward (green, front right):  Deals 13500 to 16500 Natures damage to all nearby enemies and summons guardians of nature to surround the enemy.  Flame Leviathan gains 25% more HP and decreases his fire damage taken by 10%.

In 10 mans, we made a slight adjustment to the above strat for hard(er) modes.    We send 1 ranged dps up, to handle both turrets, non hunters.   Also, one of the choppers is abandoned at the beginning to ride with the launcher Demolisher, that way both Demolishers will always have passengers, doing the Pyrite thing and dps.

Achievements:

Dwarfegeddon:  Destroy 100/200 Steelforged Defenders in 10 seconds on the Ulduar gauntlet on Normal/Heroic Difficulty.

What we did was just make a b-line towards the repair pads.   Avoid killing towers, take out the big buys mainly, which does splash down the small guys.   But anyways, clearing the path of any major threat, then use the repairs.    Then we went back towards the front pulling along all the small guys we can find, when we saw enough, on cue, blow em up.   Easy shit.

Unbroken:  Defeat Flame Leviathan on the first try without anyone repairing their vehicle on Normal/Heroic Difficulty.

Likely easiest on Easy Mode of course.   Just don't repair don't wipe.    Though, I could see this being "easy" on Hard Mode too, since we'd skip the towers, skipping chunks of trash, our vehicles should be less damaged.    Though that means only after we have Hard Mode on farm to kill it the first try.

Three Car Garage:  Defeat Flame Leviathan while in each of the following vehicles on Normal/Heroic Difficulty.

Personal achievement, just ride something different each week.   It only counts if you're in the vehicle upon Flame Leviathan's death.   Not dead, not on the turret, not anywhere else.

Take Out Those Turrets:  Destroy a Flame Leviathan Defense Turret on Normal/Heroic Difficulty.

Personal achievement, the new Denyin the Scion.   So guess after farm mode starts up we'd have to launch specific people.   (after we learned to launch people ;p)

Shutout:  Defeat Flame Leviathan without causing a System Shutdown on Normal/Heroic Difficulty.

Well we stumbled upon this in our zerg the boss fashion.  lol   Probably only possible on Easy Mode for now.    Simply, don't launch anyone, zerg away.

Orbital Bombardment:  Defeat Flame Leviathan with 1 Orbital Defense System active on Normal/Heroic Difficulty.

We chose Thorim's tower to leave up (purple).    It's quite simple really, avoid the big blue beams coming from the sky.   We liberally launched 2 dps on to the Turrets everytime to cause the System Shutdown as much as possible.  This mode currently makes him drop 2 [Emblem of Conquest] instead of 1 emblem in either mode.

Orbital Devastation:  Defeat Flame Leviathan with 2 Orbital Defense Systems active on Normal/Heroic Difficulty.

We chose to leave Mimiron's tower along with Thorim.   Mimiron leaves a big red moving laser and leaves a pile of fire (like Ignis scorch) that you don't want to stand in.   The trick is that the moving laser can cut you off while kiting and stuff around the room.    But if you can stay away and a little luck, this isn't so bad.   This mode drops a [Runed Orb] in addition to the above.    In 25 man, an extra stack of 2 orbs are dropped.

Nuked From Orbit:  Defeat Flame Leviathan with 3 Orbital Defense Systems active on Normal/Heroic Difficulty.

Hodir is a next possibility, he ice blocks people which can be melted by fire attacks (pyrite, flame jets, chopper tar fire, Mimiron's laser).    The beams are pretty fast moving light blue beams that follow people.    It's dangerous when it stops, then a few seconds later you get entombed in ice.    Avoid that at all costs, you take heavy damage and require quick fire attention to release you, so it'd likely hurt your vehicle way badly.     Make use of quick manuevering and Steam Rush to avoid those.

Orbit-uary:  Defeat Flame Leviathan with 4 Orbital Defense Systems active on NormalHeroic Difficulty.

Freya is likely next hardest to deal with.   Her beam will be at the 4 corners and spawn adds that the Demolishers should be able to take care of.    It's an added complication to constantly shift dps from FL to adds, to stocking pyrite.
