Overview The fight will begin when one person in raid enters the circle in the center of Kel'Thuzad's room. For 3 minutes and 48 seconds, adds will start heading from one of the 6 pockets in the outskirts of the room, to the center. Attacking an add still in the pocket will cause all adds of the same type (skeletons, abominations, banshees) to also head to the center. During Phase 2, the biggest trouble a raid may experience are the Frost Blasts. Melee-heavy groups may find the fight almost impossible. Healers will need to be able to adjust and heal Frozen targets immediately, and all mana users will need to pay attention to the Mana Detonation debuff, and move accordingly. Deaths to Shadow Fissures should not happen. Melee DPS and tank may find it easier to interrupt some of Kel'Thuzad's Frost Bolts, to minimize the damage done to the Main Tank. During Phase 3, one or two off-tanks will need to assigned to the Guardians of Icecrown. All DPS should focus on the boss, as this last Phase is a DPS race.
