Assembly of Iron

My own notes for explaining the Assembly of Iron fight in Ulduar.


Kill order: Steelbreaker > Runemaster Molgeim > Stormcaller Brundir.

Steelbreaker:
Tank Runemaster and Stormcaller away from raid. Tank Steelbreaker near entrance.
Blue runes can appear under bosses. Move the boss off. Players stand on the rune for a damage buff.
Fusion punch: very high damage on tank, leaves a dot which must be dispelled immediately. Melee will also take AOE damage.

Runemaster Molgeim:
Steelbreaker tank tanks him. DPS spread out. Stand in blue runes again, but move out of large green runes immediately.
Runemaster can buff himself with with Shield of Runes, which increases his damage. Dispel or spellsteal it.

Stormcaller Brundir:
DPS spread out around him. This phase needs lots of interrupts.
He casts a Chain Lightning which is interruptible.
He also casts Lightning Whirl (whirlwind) which is interruptible.
He also casts Overload, an AOE which is NOT interruptible. Melee run out!
He will sometimes fly into the air and follow a random person, dealing AOE damage. Move away from the followed person.

Hodir

My own notes for explaining the Hodir fight in Ulduar.


Please wear frost resist gear - at least 2 pieces, 3 would be better.

After the pull we need to free the 4 NPCs, then we attack Hodir.

You'll continually get a nasty dot called biting cold throughout the fight - you'll need to move or jump every few seconds to clear it.
Hodir will sometimes freeze groups of people in place - this needs to be cleansed quickly. Spread out to avoid it!
When blue circles appear on the ground, move off them immediately.
Every 30 seconds or so Hodir will make some larger blue circles appear on the ground and he will start casting Flash Freeze. Stand near the circles, and when they turn into patches of snow, move onto the snow. That way Flash Freeze won't hit you.
Players and NPCs who are hit by Flash Freeze will be ice blocked, and everyone will need to attack the ice blocks immediately to free them.
Hodir will sometimes gain Frozen Blows and will do lots of AOE frost damage.

Stand in light beams to gain 100% haste.
Stand in storm clouds to gain extra damage on crits.
Stand near fires to be protected from cold and to debuff the boss.
