I'm going to repeat what I said earlier for emphasis.

NONE OF THIS IS MY WRITING. Every speck of this came from the lovely folks at WoWHead, via ArgentSun explanations, or comments from generous readers - all from WoWHead. The ONLY thing I have done is compile it in one spot, for those of us who are lazy and need one place, and also for those of you who cannot access wowhead from work and are desperate for new patch stuff today.

Lord Marrowgar

Icecrown Citadel

The Lower Spire
Lord Marrowgar
Lady Deathwhisper
Gunship Battle
Deathbringer Saurfang

Overview

Being the first boss of a new raid, Marrowgar is not an overly complicated fight. You will need at least one soaking offtank, because of the Saber Lash cleaves (think Nalorakk). He will also shoot a line of Coldflame at a random target. The projectile moves like a spear until it hits a wall, but inflicts large amount of damage per second to anyone caught in it - simply making a few steps aside is enough to avoid it. The tanks are immune to Coldflame. Bone Spike Graveyard is another thing to watch out for - Marrowgar will choose 2 (25-player: 3) people and impale them on ice spikes. The people will take some physical damage, become incapacitated, and continue losing 10% health for every second they remain impaled. The DPS should kill the spikes as soon as possible.

The last thing to watch out for is the Bone Storm. A few seconds before it's cast, Marrowgar will emote a raid-wide warning "Lord Marrowgar falls apart and his bones begin to spin!". The spell works very much like Stormcaller Brundir's Lightning Tendrils - Marrowgar chooses a random target and pursues them for a number of seconds, moving in a whirlwind of bones, switching his targets periodically. Anyone caught by the whirlwind will take physical damage and have a physical damage DoT applied to them every 2 seconds. Must be avoided.

Normal 10-Man Abilities

• Saber Lash - Inflicts 200% weapon damage split evenly between the target and its 2 nearest allies.
• Coldflame - Inflicts 6,000 Frost damage every 1 second for 3 seconds to anyone caught by the moving line of frost.
• Bone Spike Graveyard - Hurls a spike at a random player, impaling all players between the boss and the target on Bone Spikes, inflicting 9,000 direct Physical damage, and additional 10% health as damage every 1 second until the spike is destroyed.
• Bone Storm - Inflicts 6,000 Physical damage every 2 seconds to players caught in the Bone Storm. The entire storm lasts ~20 seconds.

Lady Deathwhisper

Icecrown Citadel

The Lower Spire
Lord Marrowgar
Lady Deathwhisper
Gunship Battle
Deathbringer Saurfang

Overview

The key element of the fight is management of DPS, that will need to be split between the adds in phase 1, and Deathwhisper's mana shield.

During phase 1 Lady Deathwhisper will have a mana shield that will absorb all the damage done to her. She will attack the raid with Death and Decay, Shadow Bolts, and occasional Mind Controls, none of which should be too dangerous. The second component of the phase, the adds that come, could cause troubles.

Adds will come in waves from the sides of the room - 3 Adherents and 3 Fanatics total per wave. Adherents can only be DPSed through physical damage, and Fanatics - only by spells. The important things to watch out for with the Adherents is the Shroud of the Occult + Deathchill Blast combination used right after Lady Deathwhisper casts Dark Empowerment on them. Curse of Torpor should be removed as quickly as possible, and Dark Martyrdom should be avoided. For the Fanatics, a paladin tank is recommended. They are nothing special overall. Burn them when they have Vampiric Might, and run away from Dark Martyrdom.

Phase 2 begins when Lady Deathwhisper's mana barrier has been drained - which means that either some of your DPS should stay on the boss, or you should have everybody clear the adds quickly and use the time until the next wave to burn the boss' mana. Either way, in phase 2 she becomes active and a tank needs to pick her up quickly, as there is no threat reset. A second tank will need to be ready to pick up the boss, since she will periodically debuff her current tank with threat generation reduction debuff. The two will switch every 2-3 stacks. Everybody else should be mindful of the Vengeful Shades that will be spawned and will chase people - get away from them, let ranged DPS kill them from afar. Melee DPS might want to set up an interrupt rotation, since the Frostbolt can hurt a lot - or you can have a tank with 1-2 pieces of Frost resistance gear, Deathwhisper is not a very tank-heavy fight.

Gunship Armory

Icecrown Citadel

The Lower Spire
Lord Marrowgar
Lady Deathwhisper
Icecrown Gunship Battle
Deathbringer Saurfang

The Icecrown Gunship Battle is a unique event that serves as the third boss encounter in the Icecrown Citadel. During the event the Skybreaker and Orgrim's Hammer race to the second level of the Citadel. All players can talk to a goblin/gnome on their gunship and obtain a jetpack that allows them the jump between the two ships.

Overview

Winning the battle between the two gunships will require your raid to be carefully split between people defending your own ship, and people assaulting the enemy one.

Players staying on your faction's ship have two things to take care of. First, 3 people will need to man the cannons and attack the enemy ship. Rcoketeers will mark areas on the board and shoot (slow) rockets at them - it's easy to move away, do so. Axe Throwers/Riflemen will also shoot at people from across. Every 25% of the enemy gunship a mage will appear and freeze all of your cannons. The assaulting players will need to deal with him (see below), while the defenders deal with the squad of Reavers/Marines and a Sergeant that is being teleported. Both types gain damage and attack speed over time - so the longer they live, the more dangerous they will become. It is probably a good idea to have your ranged DPS defending, as they can avoid the Sergeant's whirlwind, and can also help the attackers (without using the jetpacks) when given an opportunity. As soon as the mage is dead and your board is secure, 3 of the defenders can re-enter the now-working cannons and continue shooting at the enemy's gunship, restarting the cycle.

The attackers have a couple of things to worry about as well. Saurfang/Muradin will try to annihilate your raid - have a tank on him, and be mindful of the stacking Battle Fury buff, which increases the commander's damage. If the buff starts getting to high, you will need to leave the ship for about 20 seconds and let it fall off. DPSing the leader is useless - have your DPS quickly burn the mages whenever they appear, and killing Axe Throwers/Riflemen and Rocketeers/Mortar Soldiers when no mages are present.

Normal 10-Man Abilities

Deathbringer Saurfang

Icecrown Citadel

The Lower Spire
Lord Marrowgar
Lady Deathwhisper
Gunship Battle
Deathbringer Saurfang

Deathbringer Saurfang, formerly known as Dranosh Saurfang, son of the most prominent orcish general, is the final boss in the entrance to the Icecrown Citadel. He is also the last boss players can fight in the first week(s) of the new patch. After him the raid instance splits into 3 wings (Crimson Halls, Frostwing Halls, Plagueworks), and progression between the wings becomes non-linear.

Overview

Saurfang is a tough fight. He does a lot of damage, he heals a lot.

There is only one phase to the fight, but that phase will really strain your DPS and Healers. Two tanks are required for this fight. The OT will be helping to kite the Blood Beasts and taunting Saurfang off the MT when they get Rune of Blood.

All players need to be spread out, so Blood Nova doesn't hit multiple people. Several hits mean Saurfang will gain more damage and energy through Blood Power. Boiling Blood is just a DoT healers will need to take care of - the fact that it does physical damage suggests that it might be removable by Hand of Protection and Iceblock. Use those abilities if you can, they will keep the Blood Power stack lower.

When Rune of Blood happens on the MT, the OT should taunt the boss at least for the duration of the Rune - or the MT can pick the boss back up when the OT gets Rune.

Mark of the Fallen Champion will happen several times during the fight. Players marked with it will likely need massive heals and survival cooldowns. Hand of Protection and Iceblock help here too, you might want to save them for Marks instead of Boiling Blood. The damage is transferred after armor reduction, so a tank with high physical damage reduction is especially helpful. With all the healing going on in this fight, it is very important not to lose people - especially when they heal the boss even more. The mark is permanent, so it is possible that you will have somebody die.

And finally, the Blood Beasts. Saurfang will summon them around him, and he will summon them frequently. You can either assign certain DPS to peel off the boss and kill the adds whenever they spawn, or you can have everyone moving off the boss. The balance between boss and adds seems similar to the last phase of Yogg-Saron's encounter. I would recommend having just enough DPS to kill a set of adds before the next one spawns, and everybody else staying on the boss at all times.

Normal 10-Man Abilities

• Blood Link - Triggers Blood Power every time Saurfang or his Blood Beasts inflict damage with an ability. Also increases Saurfang's energy by 1.
• Blood Power - Increases damage and size by 1%. Applied through Blood Link.
• Mark of the Fallen Champion - Causes Saurfang's melee attacks to hit the marked target as well as the tank. The marked player takes 4,275 to 4,725 additional Physical damage from each attack. If a marked player dies while the Mark is up, Saurfang heals for 5% of his maximum health. Cast when Saurfang reaches 100 energy through his Blood Link energizing.
• Frenzy - Increases Saurfang's attack speed by 30% and size by 20%.
• Boiling Blood - Inflicts 5,000 Physical damage every 3 seconds for 24 seconds. Used on a random target.
• Blood Nova - Inflicts 7,600 to 8,400 Physical damage to a random target and all players within 12 yards.
• Rune of Blood - Marks a target with Rune of Blood, causing Saurfang's melee attacks against that target to leech 5,100 to 6,900 health from them, and heal the Deathbringer for 5 times that amount. Lasts 30 seconds.
• Call Blood Beast - Summons 2 Blood Beasts.
• Scent of Blood - Saurfang buffs the Blood Beasts, causing them to reduce the movement speed of all nearby players by 80%, while increasing the Beasts' damage by 300%. Lasts 10 seconds.
• Resistant Skin - Decreases damage taken from AoE effects by 95%, from diseases by 70%, and from Shadow spells by 100%.

I have a word document in which I compiled all this info from wowhead PTR yesterday. Unfortunately, Blogger flips out when I try to copy and paste stuff from a word document, which gives me all kinds of headaches.

NONE OF THIS IS MY WRITING. Every speck of this came from the lovely folks at WoWHead, via ArgentSun explanations, or comments from generous readers - ALL from wowhead.com. The ONLY thing I have done is compile it in one spot, here. Normally I wouldn't even post this here, but if I can get the formatting correct, perhaps it will help some of you who want a one stop shop of reading - especially if you can't access these places from work.

I also have a word doc of the bosses from ICC 10 man that will be available starting today. If I can get this pasted in properly, I will do a separate post for the 10 man stuff.

Forge of Souls -> Pit of Saron -> Halls of Reflection

Must be completed in this order.

The Forge of Souls

Requirements: Level 80
Number of bosses: 2
Quests:

• Inside the Frozen Citadel - Given by a Dark Ranger in Dalaran.
• Echoes of Tortured Souls - Simply defeat the two bosses in the dungeon.
• Tempering The Blade - Part of Quel'Delar's chain, starting with The Battered Hilt. The Crucible of Souls is located directly past the Devourer of Souls.

Bosses

• Bronjahm: Stay either in melee range, or at 20+ yards away from him. At 20% he will use Soulstorm, which will damage everybody standing 15 yards away, and will occasionally fear the tank through the storm. Kill the Shattered Soul Fragments that will spawn throughout the fight.
• Devourer of Souls: Healing intensive fight. DPS him hard, and move when he spawns a Mirror of Souls (raid warning and a charge-like mechanic will precede it). He summons an army of souls that will do damage to the entire raid (it may be possible to interrupt it somehow, but normal interrupt mechanics don't work).

Bronjahm

Bronjahm Bronhahm, the Godfather of Souls, is the first boss in the Forge of Souls. He oversees some of the most disturbing devices the Scourge engineers have ever created - the Soul Grinders.

Abilities:

• Shadow Bolt: Inflicts 2,500 - 3000 Shadow damage, but Bronjahm will only cast this if the tank is out of melee range.
• Magic's Bane: Bronjahm will spam this ability throughout the fight as this is his 'base attack'.
• Corrupt Soul: This spell causes no damage, but lasts 4 seconds on a player. After 4 seconds a 'fragment of your soul' will spawn which will walk towards Bronjahm. If the soul is near him, he will be healed for a large amount.
• Soulstorm: At 30% health, Bronjahm will teleport to the center of the room and begin channeling this spell. It will deal 1000 shadow damage (2500 on Heroic) a second and will slow your movement speed by 50% for the rest of the fight.
• Fear: This will only be cast during Soulstorm.

Devourer of Souls

Devourer of Souls

The Devourer of Souls is a being of unknown species, the second and last boss in the Forge of Souls. It also guards the Crucible of Souls, needed to temper Quel'Delar.

Devourer of Souls

The second boss of The Forge of Souls.

• Phantom Blast 15 yd range - Inflicts 11700 to 12300 Shadow damage. It's a 2 seconds cast.
• Phantom Blast (Heroic) Inflicts 17550-18450 shadow damage. It's a 2 seconds cast.
• Mirrored Soul 100 yd range - The Overseer of Souls mirrors the targets soul! A percentage of damage from the Overseer of Souls is being mirrored with you. It's a 2 sec cast.
• Well of Souls 40 yd range - The Overseer of Souls leaps towards a target, slamming the ground creating a Well of Souls. Inflicts 2925 to 3075 Shadow damage. It's a instant cast.
• Well of Souls (Heroic) 40 yd range - 3900 to 4100 Shadow damage. It's a instant cast.
• Unleashed Souls - The Overseer of Souls is releasing tormented souls periodically. It's a 0.85s cast. Lasts 5 seconds.
• Wailing Souls - Lets loose Wailing Souls, inflicting 4875 to 5125 Shadow damage to anyone in front of her and knocking them back. This is the initial warning debuff cast on the starting player. Does not do any damage. It's a instant cast. Lasts 4 seconds.
• Wailing Souls (Heroic) - Inflicts 6825-7175 Shadow damage. It's a instant cast.

How do I not get owned by The Devourer of Souls
The Devourer fairly continuously casts Phantom Blast on the main tank if she is not doing anything else. You can intercept Phantom Blast, which I strongly recommend to do. This is her 'main' attack. While Mirrored Soul is active, any damage dealt to the Devourer will be mirrored proportionally with whoever has the debuff. This means you need to stop attacking her or you will die. Another ability of hers is called Unleash Souls. The Devourer will on occasion stop whatever else she is doing and summon a very large number of wraiths. They do not hit very hard but there are a lot of them and they cannot be targeted. Run away if the damage taken winds up being too great. And as her final ability she's having something called Wailing Souls. The Devourer will unleash a wail of souls. She does a 90 degree sweep of the room starting from the position of a random, but debuffed player. She starts wailing around three seconds after casting the debuff, and will wail for 15 seconds. Anyone caught in front of her takes a very high amount of damage ticking every 0.4 seconds.

Pit of Saron
Requirements: Level 80, Forge of Souls completed
Number of bosses: 3


Quests

• The Pit of Saron - Given when you complete the Forge of Souls.
• The Path to the Citadel - Given by Sylvanas/Jaina soon after you enter the Pit of Saron. The slaves are all over the area, and Garfrost is on the east side of the dungeon.
• Deliverance from the Pit - Given after you complete The Path to the Citadel. Krick is on the west side of the dungeon, and Tyrannus is on the north one, after a cave tunnel.
• Frostmourne - Given after you complete the instance. Go through the gate on Tyrannus' platform and enter the Halls of Reflection.
• Reforging The Sword - Part of Quel'Delar's chain, which starts with The Battered Hilt. Saronite Bars all over the area where the slaves are, and the Forgemaster's Anvils are around Forgemaster Garfrost, who drops the Hammer.

Bosses

• Forgemaster Garfrost: Spread out and avoid saronite chunks; break LoS with the boss (using saronite or anvils) to drop the debuff stack.
• Ick & Krick: Avoid the poison pools on the ground; run away when being Pursuit. Focus on avoiding the Explosive Barrage when he casts it - easily avoidable by constant movement. Break LoS during Poison Nova, or be 20+ yards away.
• Scourgelord Tyrannus: Stay out of marked circles on the ground, and run away if you are targeted for a frost attack by Rimefang (red hunter's mark-looking spell). Kite the boss when he "surges with dark might" if you are not overgearing the place. Optionally you can slow DPS down during Overlord's Brand.

Forgemaster Garfrost

Forgemaster Garfrost is a flesh giant covered with ice, whose duty is to forge saronite weapons and armor for the Scourge. He is one of the two encounters you will need to defeat before "unlocking" the passage to Scourgelord Tyrannus and the Halls of Reflection. Garfrost is considered the first boss encounter in the zone.

Overview

Engaging either Garfrost or one of his skeletal smiths will cause all the smiths and the boss himself to attack you, so mind your pulls.

Garfrost has only a couple of abilities you will need to watch out for. He has a party-wide aura that inflicts Frost damage and applies a debuff that increases Frost damage taken. The debuff is applied every 3 seconds and stacks. The solution to this problem lies in the other thing he does - throwing saronite boulders. Garfrost will aim at a player and throw a huge saronite chunk at them. The stone will do damage and knock the player back (unless they move), but will also provide cover for the entire party to hide behind, break line of sight for 3 seconds, and let the Frost debuff fall off. Tanks can use the boulders when Garfrost runs to one of his forges to grab a weapon.

Regular Abilities

• Permafrost - Party-wide aura that inflicts 200 Frost damage to enemies in line of sight, and applies a stacking debuff that increases Frost damage taken by 10% for 3 seconds. The aura ticks every 2 seconds.
• Throw Saronite - Throws a saronite boulder at the location of a random target, knocking any players in 6 yards range away, and inflicting 3,500 Physical damage.
• Forge Frostborn Mace - Increases Frost damage by 100%. Used when Garfrost's health reaches 66% and 33%.
• Chilling Wave - Inflicts 1,850 Frost damage to enemies 65 yards in front of the caster.
• Deep Freeze - Reduces the movement speed of a random target by 50%, and causes them to take 4,000 Frost damage after the spell expires. Lasts 14 seconds.
• Thundering Stomp - Knocks enemies in melee range in the air and stuns them for 2 seconds.

Heroic Abilities

• Permafrost - Party-wide aura that inflicts 400 Frost damage to enemies in line of sight, and applies a stacking debuff that increases Frost damage taken by 20% for 3 seconds. The aura ticks every 2 seconds.
• Throw Saronite - Throws a saronite boulder at the location of a random target, knocking any players in 6 yards range away, and inflicting 5,500 Physical damage.
• Forge Frostborn Mace - Increases Frost damage by 200%. Used when Garfrost's health reaches 66% and 33%.
• Chilling Wave - Inflicts 2,000 Frost damage to enemies 65 yards in front of the caster.
• Deep Freeze - Reduces the movement speed of a random target by 50%, and causes them to take 6,000 Frost damage after the spell expires. Lasts 14 seconds.
• Thundering Stomp - Knocks enemies in melee range in the air and stuns them for 2 seconds.

Krick

Krick is a leper gnome in service of the Lich King. He is part of one of the two encounters you need to defeat before "unlocking" the passage to Scourgelord Tyrannus and the Halls of Reflection. Ick & Krick are considered the second boss encounter in the zone.

Overview

The fight is fairly simple and straight-forward, as can be expected from a 5-Player boss. Avoid the Toxic Waste and Explosive Barrage; run away when Pursuit is cast, and run out of line of sight when Krick casts Poison Nova. As soon as Ick is dead, a short scene will be triggered, and Krick will die at the end of it - without player intervention.

Ick

Ick is a plague eroptor that serves as a mount for the leper gnome Krick. He is part of one of the two encounters you need to defeat before "unlocking" the passage to Scourgelord Tyrannus and the Halls of Reflection. Ick & Krick are considered the second boss encounter in the zone.

Overview

The fight is fairly simple and straight-forward, as can be expected from a 5-Player boss. Avoid the Toxic Waste and Explosive Barrage; run away when Pursuit is cast, and run out of line of sight when Krick casts Poison Nova. As soon as Ick is dead, a short scene will be triggered, and Krick will die at the end of it - without player intervention.

Scourgelord Tyrannus

Final boss goes RAWR!

This boss has quite a bit of health for a 5-man (over a million in heroic) but the fight is very straight forward.

Occasionally Rimefang will mark a target. The mark stays where the target was standing and the marked player must run away from the mark. Rimefang will bombard the marked area with a patch of frost.

The boss hits pretty hard and also has an array of attacks at his disposal: notably an AoE stun, a knockback, an enrage, and a debuff.

Of his abilities the debuff is the most dangerous (Overlord's Brand is the name of it if I recall). It will cause any damage the debuffed target deals to the boss to also deal damage to the tank. This can make short work of even a very geared tank. The player afflicted by Overlord's Brand should cease DPS immediately.

His enrage is also very important as it makes the boss untankable for a short period of time. The boss, in addition to dealing incredible melee damage, will also have his speed increased. He will always knock the tank back before enraging. He also momentarily loses his target and takes a couple of steps backward. The only way to survive this enrage is to put permafrost left over by Rimefang in between the tank and the boss, because this slows him and allows him to be kited.

Tip: If you tank the boss with your back to a patch of permafrost, his knockback will send you over the frost forcing him to immediately walk over it and become slowed.

The AoE stun is very brief and can be mostly ignored. HoTs on the tank are helpful as the boss continues to melee.

All of this information is pertinent to the PTR and is subject to change.

Halls of Reflection

Halls of Reflection is the third and last wing of the dungeon complex known as the Frozen Halls. The Forge of Souls and Pit of Saron must be completed before a player can enter the Halls of Reflection.

Falric

Falric, a captain for Arthas in both life and death, is the first boss in the Halls of Reflection. He will engage the party after 5 spirit waves have been defeated.

Overview

After the event with the Lich King, Uther, and Jaina/Sylvanas, the Lich King will summon Falric and Marwyn, who in turn will summon a group of ghostly soldiers. The soldiers will come in waves of 3-4 per wave, and after the 5th wave Falric will engage the group.

The fight against the dead captain is mostly about quick removals of magic effects. Impending Despair will stun its target after 3 seconds if not removed, and Quivering Strike will frequently drop the tank's dodge by 20%. Other than those two, Defiling Horror will send the entire party fleeing in horror for 4 seconds, while taking damage, and Falric's Hopelessness aura will reduce all players' damage and healing done by 20% (Heroic: 40%).

Regular Abilities

• Hopelessness - Reduces all damage and healing done by players by 20%.
• Impending Despair - Causes Despair Stricken, stunning the target for 6 seconds, if not removed after 6 seconds. Magic effect.
• Defiling Horror - Inflicts 2,500 Shadow damage every 1 second for 4 seconds, and sends all players fleeing in horror. Falric will not attack while the Horror lasts.
• Quivering Strike - Inflicts 60% normal melee damage and reduces the target's chance to dodge by 20% for 5 seconds. The dodge reduction component is a magic effect.

Heroic Abilities

• Hopelessness - Reduces all damage and healing done by players by 20%.
• Impending Despair - Causes Despair Stricken, stunning the target for 6 seconds, if not removed after 6 seconds. Magic effect.
• Defiling Horror - Inflicts 4,000 Shadow damage every 1 second for 4 seconds, and sends all players fleeing in horror. Falric will not attack while the Horror lasts.
• Quivering Strike - Inflicts 100% normal melee damage and reduces the target's chance to dodge by 20% for 5 seconds. The dodge reduction component is a magic effect.

Marwyn

Marwyn, the Lich King's second captain from his life as a paladin, is the second boss in the Halls of Reflection. He will engage the party after the 10th spirit wave has been defeated.

Overview

There is a short break betwee Falric's death and the 6th spirit wave, during which the party can replenish mana and health. Another set of 5 waves follows the break, and then Marwyn attacks.

If Falric is more of a warrior-type of boss, Marwyn is more of a death knight. He uses Obliterate frequently, and focuses on corruption attacks. Well of Corruption, spawned underneath a player, will cause Corrupted Flesh, which stacks a Corrupted Touch DoT on its target. Shared suffering causes damage done to the boss to be transferred to the target of this removable magic effect.

Regular Abilities

• Obliterate - Inflicts 18,000 Physical damage, mitigated by armor.
• Shared Suffering - Inflicts 4,000 Shadow damage every 3 seconds for 12 seconds. If dispelled, splits the remaining damage equally between all players. Magic effect.
• Well of Corruption - Causes Corrupted Touch every 2 seconds, increasing Shadow damage taken by 30%, stacking. Affects only players in the well. Lasts 8 seconds.
• Corrupted Flesh - Reduces maximum health by 25% for 8 seconds.

Heroic Abilities

• Obliterate - Inflicts 26,000 Physical damage, mitigated by armor.
• Shared Suffering - Inflicts 6,000 Shadow damage every 3 seconds for 12 seconds. If dispelled, splits the remaining damage equally between all players. Magic effect.
• Well of Corruption - Causes Corrupted Touch every 2 seconds, increasing Shadow damage taken by 75%, stacking. Affects only players in the well. Lasts 8 seconds.
• Corrupted Flesh - Reduces maximum health by 50% for 8 seconds.

The Lich King

Wrath of the Lich King

Wrath of the Lich King is actually a gauntlet event where you must escape from the Lich King, that serves as the third boss encounter. It has no single strong elite to be fought as a boss.

Overview

Soon after defeating Falric and Marwyn, players will find Jaina/Sylvanas locked in combat with the Lich King, with the latter clearly winning. Moments before your leader dies, she will freeze the Lich King in place and urge you to run and try to escape.

The gauntlet event consists of the party killing waves of undead, while Jaina/Sylvanas break 4 walls of ice. Each ice wall is broken as soon as the current wave of Scourge minions dies. The time bomb in this event is the Lich King, who slowly catches up with the group; if he reaches Jaina/Sylvanas, he will kill her and then proceed to annihilate the entire party. Fortunately he is surrounded by the Remorseless Winter aura, which reduces his (and players?) movement speed by 75%.

Every time Jaina/Sylvanas break an ice wall, the Lich King summons more minions than he did in the previous wave.

Waves

The waves consist of 3 types of adds: Raging Ghouls, Risen Witch Doctors, and Lumbering Abominations. Each subsequent wave has more of what the previous one had (the only exception is the first wave, which doesn't have abominations at all, while the second one has one).

• Raging Ghoul
• Risen Witch Doctor
• Lumbering Abomination
