Kel'Thuzad - Naxxramas boss guide

Tactics for Kel'Thuzad in Naxxramas 10/25 for WoW 3.3.5a: waves of adds, Ice Blast, Cleft of Darkness, Mana Burst, Icecrown Guardians and T7 tokens on the head.
Review
Kel'Thuzad is an archlich, the master of Naxxramas and the final boss of the raid. The battle is in three phases: first, for almost four minutes, a raid from the center of the hall fights off waves of undead, while the invulnerable lich is channeled on the throne; then CT enters the battle himself - kicking Ice Bolts, void zones Dark Rifts, Mana Bursts and deadly Ice Blasts; at 45% the Lich King sends him the Guardians of the Icecrown. Drop of T7 tokens on the head and top weapons of the shooting range.
- Phase 1 lasts exactly 228 seconds (according to the script) - the raid stands in the center of the circle, no one approaches the alcoves and does not touch the adds ahead of time.
- Soldiers of the frozen wastelands explode with a dark flash on contact - they are met by range and frostball traps, not a step forward.
- After the first Ice explosion, everyone gets used to standing at least 10 meters from each other - a splash on neighbors turns one victim into three.
- A manaizer with a Mana Burst runs away from everyone: after 5 seconds, 10% of the maximum mana will be burned out of him and hit around with damage 10 times the amount burned.
- Healers keep instants under Ice Blast: 26% max. HP per second 4 seconds - the target dies faster than a large heal cast.
Combat phases
KT is invulnerable and canalizes on the throne, the exit from the hall is sealed by adds. From six alcoves climb: Soldiers of the Frozen Wastes (slow, explode on contact - kill with range; new one every ~3 sec), Unstoppable Abominations (tankable; Mortal Wound -10% heal with stacks + Frenzy below 35% HP; every ~18 sec) and Soul Weavers (Cry of Souls - heavy darkness damage with knockback; every 30 sec). The adds are fixed on the first target - do not pull them into the raid.
- Soldiers - Range DPS only
- Abominations - on tank (Fatal Wound, Frenzy)
- Soul Weavers - Quick Focus
- Stand in the center of the circle
CT is activated: the tank takes it in the center, the raid scatters in groups 10+ meters from each other. A single Ice Arrow is kicked (otherwise 10–13k ice per tank), runs out from under the feetCleft of Darkness, carrierMana Burst runs away from everyone, victimsIce Blast instantly healed. In 25, every 90 seconds three players are taken control ofChains of Kel'Thuzad.
- Ice Arrow Kick
- Cleft of Darkness — run out
- Mana Burst — run back
- Ice Blast- instant heal
- Chains (25 only)
CT calls the Lich King - 2 (10) / 4 (25) Icecrown Guardians emerge from the portals. They are picked up by the off-tank and taken to the side: every 15 sec, the Blood Tap hits for 125% weapon damage and stacks +15% damage to the guard. The guards are not killed - the boss is burned out before the stacks become lethal. All phase 2 mechanics continue.
- Offtank collects Guardians
- Blood Tap Stacks = Soft Timer
- Burst boss with all CDs
Abilities
Positioning
Phase 1: the entire raid in the central circle of the hall, with their backs to each other, front to the alcoves - the soldiers are shot as they approach, the abominations are received by tanks, the weavers are concentrated. Phase 2+: the tank keeps the CT in the center, the raid - in a ring around in groups of 1-3 people with gaps of 10+ meters.
Role Tips
- In P1, do not bring abominations to the raid - Mortal Wound stacks quickly, change at 4-5 stacks.
- Selecting a CT at the start of P2 is the moment of truth: the boss comes out of the channel aggressive, the yawning tank gives the raid frostbolt one-shots on rags.
- Offtank in P3 - all saves and external CDs: to 5-6 stacksGuard Bleed they hit harder than the boss.
- The guards taunt normally - pick them up right at the portals before they eat the healers.
- Ice Blast - your main exam: 104% HP in 4 seconds. Shield/Repentance/instant swaps in the first second.
- Don't stand near other healers - doubleIce Blast orMana Burst a bunch of heals ends the battle.
- In 25, keep an eye on who the Chains took: an enchanted healer with a +200% boost heals the boss - they control him, they don’t cut him.
- P1 - time to save mana: further 10+ minutes of intense healing without pauses.
- We kill P1 soldiers strictly at a distance - miles do not approach them at all.
- Kick rotation to a single Ice Arrow is mandatory: each missed one is minus half a tank.
- FromClefts of Darkness they run out instantly, even in the middle of a burst - dead DPS is worse than lost GCD.
- In P3, there is no DPS against Guardians - every second not against the boss lengthens the race with Blood Tap stacks.
