Phase 1

1. During this phase you will be fighting waves of mobs that are moving towards you only!
2. Soldier of the Frozen Wastes, if they touch anyone in the raid they will deal 3,000 - 4,000 damage to the whole raid. It is best to stick ranged DPS on these, a hunter works great.
3. Soul Weaver do a nasty knockback to 3 players dealing 6,400 - 8,600 damage. These move very slow, everyone but the person killing the Soldiers should be attacking these.
4. Unstoppable Abomination need to be tanked, tanks should alternate with these guys because they do a stacking Mortal Wound, which reduces healing by 10%.
5. After 3 and a half to 4 minutes Phase 2 will being.

Phase 2

1. Everyone needs to position themselves at a minimum of 10+ yards away from everyone else to avoid Detonate Mana.
2. Melee needs to be spread perfectly in a diamond shape and at max range.
3. There needs to be a silence rotation order on Kel'Thuzad, silencing the Frostbolt is very important.
4. If Shadow Fissure is cast on a melee target or tank then all of the melee need to reposition or will die.
5. When Chains of Kel'Thuzad is cast everyone must stop and allow the tank to regain aggro.

Phase 3

1. This phase starts at 45% health.
2. Save all your cooldowns and big abilities for this phase, if you take too long the Guardians will become too strong and wipe your raid. It's a DPS race from here.
3. 4 Guardians of Icecrown will be sent by the Lich King, these need to be picked up by your off tanks and tanked in the alcoves. It is advised to tank them close together, if one of the off tanks is mind controlled it will be much easier to pick up.
