Ulduar (25) Boss Guides - Wrath Classic (WOTLK)

Flame Leviathan

Summary

Talk to Brann Bronzebeard to start the encounter.
After killing the mobs guarding the gate, Flame Leviathan will spawn.
If you are targeted by
Pursued
, run away from the boss and use your movement ability on your vehicle. Switches target every 30 seconds.
Salvaged Choppers DPS with
Sonic Horn
.
Salvaged Demolishers use
Hurl Boulder
and
Hurl Pyrite Barrel
(Stacks to 10) from range. The passenger can use
Mortar
to DPS.
Salvaged Demolishers passengers can shoot down Pyrite which is used for
Hurl Pyrite Barrel
from the sky, and collect it with
Grab Crate
.
Salvaged Siege Engines use
Ram
and interrupt
Flame Vents
with
Electroshock
. The passenger can use
Fire Cannon
to DPS.

Notes

Salvaged Demolishers stacking Pyrite should be more than enough for completing normal mode. You don't need to worry about causing a
System Shutdown
.

Flame Leviathan (HM)

Summary

Talk to Lore Keeper of Norgannon to start the encounter.
Everything mentioned in the normal mode strategy will remain true in Hard Mode.
Flame Leviathan will have 40% more health for each tower not destroyed.
Tower of Storms increases Flame Leviathan's Physical Damage by 25%, and spawns pillars of light, dealing damage to any vehicle inside it throughout the fight.
Tower of Flames increases Flame Leviathan's Fire Damage by 50%, and will spawn fiery orbs that fall from the sky and leave behind a flame trail throughout the fight.
Tower of Frost will spawn a beam that follows players throughout the fight and once it stops, it will freeze all nearby vehicles and deal damage over time. Freeze can be broken with a Fire spell.
Tower of Life decreases Fire Damage dealt to Flame Leviathan by 10%, and will spawn a large add, and a group of small adds throughout the fight.
Salvaged Demolishers maintaining 10 stacks of the DoT with Hurl Pyrite Barrel will be crucial to success because of Flame Leviathan's massive health pool.
In order to cause a
System Shutdown
, Salvaged Demolishers will use
Load into Catapult
, and the Salvaged Demolishers driver will use
Throw Passenger
. The player will need to destroy all Leviathan Defense Turrets to cause a
System Shutdown
.
Once this happens, the player can parachute to the ground, and a Salvaged Chopper should pick them up, use
First Aid Kit
, and take them back to their Salvaged Demolishers.
Salvaged Choppers use
Tar
at the corners of the room to deal with the adds.
Keep in mind, when
Throw Passenger
is used, that Salvaged Demolishers no longer has someone to collect Pyrite for them. This can be remedied by having 3 people assigned to one Salvaged Demolishers. One player can use
Load into Catapult
before the fight starts.

Notes

Self-sufficent Ranged DPS such as Warlocks, Shadow Priests, or Balance Druids are great candidates to kill the Leviathan Defense Turrets.

.
Healers watch out for raid wide damage caused by
Tympanic Tantrum

Notes

Raid cooldowns such as
Divine Guardian
will help deal with

Same as normal mode strategy in this phase.

2 Alive

Once Molgeim dies, Brundir and Steelbreaker will gain new abilities.
Brundir will gain
Lightning Whirl
and Steelbreaker will gain
Static Disruption
.
Positioning for this phase will be important for dealing with
Static Disruption
as it will only target players not in melee range of Steelbreaker.
Ranged should position themselves at max melee range in front of Steelbreaker, and Brundir will be tanked right behind Steelbreaker which will put the Ranged group out of range from
Overload
.
Melee DPS won't be in danger from
Static Disruption
, because Brundir is being tanked right behind Steelbreaker, so they will be in melee range.
Atleast one player without the
Static Disruption
debuff must always be outside of the group to soak it because
Static Disruption
will not target a player who already has it.
There will be raid wide damage caused by
High Voltage

Meltdown
can run away and not explode on the raid.
Steelbreaker will heal for 20% of his health (10% if a healing debuff is applied), every time a player dies, including the Tanks who die from
Meltdown
.

(Void Zone). It will revive itself in about 30 seconds.
Try to move away from the
Seeping Feral Essence
to avoid running through it when

Feral Pounce
when it revives.

The first wave type contains Detonating Lashers. These adds are untankable and will randomly run from player to player.
Stacking up will help control these adds, and make it easier to AoE them down, but make sure not to kill them all at once because they explode on death. When they get low, single target them down.
The second type of wave contains an Ancient Conservator. Make sure to stand near the Mushrooms to avoid being silenced by
Conservator's Grip

Tidal Wave
.
Snaplasher gains a stacking buff every time it is attacked increasing its damage. This buff will fall off after not receiving an attack for 4 seconds.

buff and heal itself and everyone around it.
Once it heals back to full, bring it back with all of the other Immortal Guardians.
Off Tanks should alternate picking up Immortal Guardians as they spawn.
There will be a ton of Immortal Guardians spawning throughout the fight. It is imperative to make sure DPS aren't over AoEing and doing useless damage to them when they are at 1% health.
Healers try to top off Tanks before
Deafening Roar
.
If you do 1 Keeper Yogg-Saron, it will be the same as normal mode strategically, with
Deafening Roar

Algalon the Observer

Phase 1

Healers watch out for spike damage on the Main Tank from
Quantum Strike
.
Off Tanks must be ready to
Taunt
Algalon when the Main Tank is at 4 stacks of
Phase Punch
. He will cast this every 15 seconds.
Sets of four Collapsing Stars will spawn randomly throught the encounter. They will lose 1% health per second.
Coordinate killing the Collapsing Stars one at a time as they explode on death, dealing damage to the entire raid. One or two DPS should be assigned to this.
When a Collapsing Star is killed, it will spawn a Black Hole.
Every 90 seconds Algalon will cast
Big Bang
. The entire raid except 1 player will need to walk over a Black Hole to avoid it.
Avoid the Dark Matter adds in this realm.
One player must be left behind and survive or else Algalon will wipe the raid with
Ascend to the Heavens
.
A Shadow Priest with
Dispersion
is a good candidate to be left behind.
Everyone will be taken back to the normal realm after
Big Bang
finishes.
Throughout the fight, 3
Cosmic Smash
zones will appear on the ground that look like red void zones, move at least 10 yards away from them.
Kite Living Constellations through Black Holes to kill it. It will also cause the Black Hole to disappear.

Phase 2

Starts at 20% health.
Any Collapsing Stars and Living Constellations will disappear and stop spawning.
Quantum Strike
,
Phase Punch
,
Cosmic Smash
, and
Big Bang
will continue to be casted.
All Black Holes will disappear, but four new Black Holes will spawn in set positions around the center of the room.
Unleashed Dark Matter will spawn at the start of the phase and every 30 seconds after from the Black Holes.
An Off Tank should pick these up and tank them off to the side.
DPS focus Alagon and ignore the adds.

Notes

Immune effects such as
Ice Block
from Mages and
Divine Shield
from Paladins will not work on
Big Bang
.
Death Knights can use
Death Grip
and classes with knockbacks such as Balance Druids'
Typhoon
