Icecrown Citadel is a raid in the World of Warcraft game. The minimum level for this dungeon is 80. The instance was released in the Wrath of the Lich King expansion. The raid contains 12 bosses. The end boss of Icecrown Citadel is The Lich King.
Running this dungeon increases your reputation for the Ashen Verdict faction. How much you get depends on the level and the race of the character. Humans have a racial bonus of diplomacy which means they get more rep from killing and doing things than the other races.
Icecrown Citadel is the penultimate raid of the World of Warcraft - Wrath of the Lich King where you face the controller of the Scourge, Arthas Menethil, a fallen Paladin now a Death Knight. Also inside is Professor Putricide, the made scientist who created the Scourge virus and converted the many dead humans, elves and like to the Forsaken. The Lich King sits at the very top of the Citadel but you won't be able to see him unless you're in the raid instance so no bomb dropping.
It is the penultimate raid because they released The Ruby Sanctum raid to keep people going before World of Warcraft - Cataclysm was released later in the year. This raid comes in two parts, 10 man and 25 man. As such there are achievements for both levels and mounts for both sets of acheivements. They look smilar, both are frostbrood vanquisher bone dragons like the Sandragosa boss, one of the last bosses in the raid.
The raid is split into two, upper and lower level, separated by a requirement to get a "plane" to the upper part. There are portals between each section so you don't need to go through every part to get to the part you want. There is no exit point when you reach the Lich King. You either have to jump off the edge and die or Hearthstone back to your inn to get out, that is unless there is a mage in the group.
The entrance of the Icecrown Citadel is at the southern central area of the zone, with Wintergrasp. The nearest flight points to the entrance is the Flight point in Wintergrasp or
For plate wearers there is the Shadowmourne Axe questline that will eventually reward them with a legendary axe and a mount (Crimson Deathcharger). The quest should still be available to start if you are still after it. You do need to realise that there are a couple of quests that involve having a group of three or four people so that you can drain their life force from them. The Invincible's Rein drops on 25 an HC if you can make it that far. You will need a healer in the party whether you go solo or as a group for Rescue Valithria Dreamwalker boss encounter as the boss needs to be healed.
In the Citadel area is an entrance to another part of the building and there you will find three dungeons that were released at the same time as the raid opened. One of those dungeons, Halls of Reflection will see you go up against the Lich King but you will not be able to kill him, his health will not fall below 1 point, I've tried.
Lord Marrowgar is the first boss in the raid instance. He is essentially a guard which is easy to kill. The main things to know about this boss is that he'll do a whirlwind every so often so you need to get out of his way. The tank can't control him when he whirlwinds, only when he comes out of it. You need to watch your stepping otherwise you might get boned and when that happens you become incapacitated and have to either wait for the timer or be freed by a colleague. After the fight, run up the slope to the right of the fight.
Lady Deathwhisper loves to talk and keeps on talking. When you arrive in the room, you need to kill both groups of trash, be careful not to pull both groups at the same time if you can help it. After the two trash groups are down, go for both spiders, one at a time. Once all the trash is dead, go for the boss. At the start of the fight, the boss will have a shield that can't be removed and she'll be protected from any damage you might do. If you do get some damage on her, she'll repair herself. The shield comes down after you have cleared all the trash adds and its fairly simple after that. Back when ICC was the top raid, you used to have three tanks, the third tank used to be a hunter or a plate warrior who would deal with the trash at the back of the room. One tank for the boss, one tank for the side trash and third for the back trash. Now adays its not needed to have three tanks, just tank and spank the one boss for simplicity. When Lady marks an area of the ground green, you need to move out of the area as quickly as possible otherwise it will cause you damage.
After Lady Deathwispher, you would take the lift up to the top and then round the balcony to the gunship. You must clear all the trash otherwise you won't be able to get on the boat and be teleported off even if you're a very high level character. Once the trash has died and you are on the boat, talk to the Dwarf or the Orc to start the fight. The enemy flying ship will come from above. Ranged players usually take control of the cannons with melee dealing with jumping across or dealing with those that port to your boat. Before the fight has started, those that plan to jump across should talk to the goblin and get and equip a rocket pack to jump across. During the fight, the enemy will call out a Frost Mage to freeze the canons. One tank and dps need to jump across. The tank takes on the leader of the enemy ship whilst the dps kill the frost mage. You won't be able to kill the enemy boss, once the mage is dead, jump back. When you get back, the ranged should jump back into the canons and fight again. The number of canons available is dependent on the level of the raid, either 10 man or 25 man. The canons now scale with level so the higher you are, the heavier the damage that the canons do now. Once the fight is over, the rockets packs are disabled and removed.
To start the fight, you need to talk to your leader of the battalion so for the Alliance, this would be Muradin, the Dwarf who will call out the Orc. Muradin will charge at Saurfang but be incapacitated so won't be helping with the fight. During the fight, he will summon blood beats which need to be kitted away from the boss and killed. The amount of beasts that appear depends on the level that you are doing, i.e. 10 man or 25 man.
After the fight, Saurfangs father turns up to take his son's dead body away, High Overlord is immune to attack so just leave the area unless you want to see the interaction between the Alliance and Horde characters. The loot is a chest in the corner of the fight area to the right of the entrance to the building.
Festergut and his brother Rotface are two ugly abominations. They look the same but they do different tactics to kill the players. Festergut will populate the area with orange gas and will make you sick. If you're high enough, the damage shouldn't be too much. When the Spores appear, if you're soloing, you can just ignore. You should spread out around the room. If you're doing it in a group, when the spore goes to one of the players, you should crowd round the player to share the damage. Once the spore has been used, go back to your attacking position and continue. On the way out, don't forget to open the gas valve so you can get to the Professor.
Rotface is the second ugly abomination that you will encounter in the Icecrown Citadel. He is slightly different in looks, different eye colour for example to his brother. Unlike his brother, he uses ooze pools from the ground to affect the players. You need to move out of the way when when the oozes appear from out of the ground. Its an easy boss. Once you have killed the boss, don't forget to open the valve or you won't be able to get to the Professor.
Professor Putricide is the creature that is probably responsible for the creation of the virus Scourge and there responsible for turning Alliance players into the Forsaken. The fight is a three stage fight. At the end of the first and second stage, he'll incapacitate you whilst he drinks a concoction and turn more hideous. Whilst frozen, you just have to wait. During the phases, ooze pools will appear on the ground, they can be soaks up by players on drink from the potions on Putricides tables. If you're soloing the boss, you shouldn't worry about the ooze. If you drink the ooze at the wrong time, the fight will reset and you'll have to start all over again. During a group fight, coloured oozes will come along the ground and when hit will cause damage to the player so be prepared, move away as far as possible from the oozes.
Its really the Blood Council, Prince Valandar is the middle of the three princes that is is resurrected by the vampire queen Lana'thel. The three share the same health and you should target the person with the health rather than any of the those that aren't alive. During the fight, a purple orb will appear, this needs to be dpsed. If you are doing this solo, you can ignore the orb and just concentrate on the Prince with the most health and get him down. Once you have killed him, a doorway will open and you can step through and go all the way up to the next boss.
Lana'thel doesn't use adds, she doesn't need to, she's got you and your raid party, that is if you're not doing it solo. During the fight, she'll bite someone and turn them into a vampire who then needs to bite someone else and so on and so forth so that they don't be compromised and fall into the hands of the Vampress. Once the boss is dead, a chandelier at the top of the steps will fall allowing the group a quick exit back to the ground below. If you're doing the Shadowmourne quest, you need a minimum of three people and be doing it on 25 man.
Unlike all other bosses, you don't kill the boss, you must rescue her. When you first enter the room, she is being held down by four liches which should be killed or ignored, depending on how high you are when you do it. If you're high enough, just ignore them. If you're not, kill them. The aim of this encounter is to ensure Valithria gets to full health. If you have a healer in the group, heal the boss as quickly as possible and then she'll fly away. Whilst you are healing, adds will come from the walls, they must be killed otherwise they will damage the players and the dragon which you must save.
Green portals will open around the boss, if you have the healers for it, enter the portals and fly round collecting the green orbs. In the alternate reality, there are no adds to worry about, you just need to collect the orbs. You'll be able to fly in this area so be sure to jump up to fly up.
When you leave the Ice Crown after having survived the Gauntlet, you will come out onto a balcony two group groups of baby skeletal dragon trash with a Vakyll controller. Simply despatch both groups with ease then stop. They'll be two skeletal drakes land, Rimefang and Spinestalker. They can be tackled individually but the minute both are dead, Sindragosa will appear. Once the two drakes are dead, run back into the Citadel and Sindragosa will reset giving you time to sort out the groupings and locations where you want to be.
After the reset, Sindragosa will be flying around but will land when you approach the area. Every so often, the drake will take to the sky and breathe down on one or two people. These breathed on people will be turned into ice blocks. The other players need to hide behind the ice blocks to protect themselves. Once the mini-phase is over, you need to break open the ice blocks and heal up the players and continue the assault.
Entrance to fight the Lich King is only possible when all the other bosses in the raid have been killed. The Lich King sits on his throne in the open at the top of the Citadel. You can go up to the boss and do whatever you want to him and he'll not react unlike other bosses. The only way to start the encounter is to talk to High Lord Fordring. After the short cinematic action, Fordring will be frozen out and can't help the players until the very end if you make it that far
Phase 1, simple tank and spank, making sure the adds that he sends don't kill anyone. The adds will come the ground and you need to kill them as quickly as possible otherwise people will die.
Phase 2, Lich King will run to the centre of the room. He'll start to fire ice balls at the group. Occasionally spectral equivalents of the players will be created and attack the group, the spectral images are bigger than the actual players so there's no mistaking the player from the add. Ranged dps, in particular hunters need to shoot the balls to stop them coming at people. If the balls hit you, you will fly off the edge.
Phase 3, The Lich King will resurrect the platform and start creating black holes in the ground, if you step into these black holes, you will go off the edge. Valkylls will fly in and take some off the edge, these Valkylls need to be killed before the player is killed. The tank is never attacked by the Valkylls, if you're soloing, you won't be attacked either. The Valkyll will just fly by their masters side.
Phase 4, a short dialogue will appear and Fordring will break freee from the ice and attack the Lich King. The Lich King will be unable to move or summon anyone and from that moment on, he's as good as dead. Even if you're super high level, this phase will take place, the Lich King will have 1 hp.
That's it, well done, the Lich King is dead and you'll see a cinematic clip of what happened afterwards. If you missed it, it can be viewed by clicking on the water fountain in Dalaran.
