Phases

Kel'Thuzad has two "phases", each with its own hero power. He starts in Phase 1 and will enter Phase 2 immediately as soon as all of his Armor is gone, even if this happens in the middle of the player's turn, without allowing the player to take any further actions, as he will strike the End Turn button with a bolt of lightning. This makes it a good idea to take all desired actions before removing his last point of Armor. Kel'Thuzad is also capable of switching to Phase 2 preemptively ("Fool! You have spread your power too thin!") at turn 11.

When Kel'Thuzad enters Phase 2, his hero power will change to Chains (Normal/Heroic), and he will summon 2 Guardian of Icecrown (Normal/Heroic).

Special card interactions[]

Animal Companion

If a player uses Animal Companion during the encounter, Mr. Bigglesworth will be summoned in place of the usual uncollectible Beasts. It is possible to have multiple Mr. Bigglesworths on the board at one time.[1]

If Mr. Bigglesworth is given Taunt, Kel'Thuzad is able to ignore it and will be able to attack your other minions or hero instead. This is "very much intended".[2]

If you manage to transform Kel'Thuzad into a different hero, such as Lord Jaraxxus or Ragnaros the Firelord, Animal Companion will spawn a regular Beast companion.[3]

If you use Call of the Wild during the encounter, all 3 Animal Companions will be summoned alongside Mr. Bigglesworth

Tips[]

  • One way to take advantage of this boss is to use Majordomo Executus. Kel'Thuzad will try to take control of it, disregarding its Deathrattle. This strategy involves "feeding" Kel'Thuzad with Executus and killing both of them on the next turn. One example would be a Priest deck involving a Shadow Word: Death and 2x Mind Blast played the turn after Executus switches teams.

Before match

Kel'Thuzad
This next fight will not be easy. I hear the boss is ALL POWERFUL... and very handsome.

Introduction

General
We finally meet.
Anduin - "The Light shall bring victory!"
How naive! Don't you remember what happened to Uther?
Garrosh - "Victory or Death!"
Really? Death it is, then.
Is this a trick question? Looks like death for you!
Gul'dan - "Your soul shall be mine!"
Well, someone's soul shall be someone's.
Jaina - "You asked for it!"
I most certainly did NOT. You barged into MY floating necropolis!
Malfurion - "I must protect the wild!"
The wild? Then what are you doing in Naxxramas?
Rexxar - "Let the hunt begin!"
Be my guest.
Thrall - "For Doomhammer!"
You're fighting for a hammer? Ok then.
Uther - "I will fight with honor!"
...and I will fight with huge minions and devastating spells. Good luck!
Valeera - "Watch your back."
Ok. I. Will.

Defeat

Kel'Thuzad
Victory for Kel'Thuzad! Did you hear that Bigglesworth?!
Give me a K! Give me a T! What's that spell?
I just completed a quest to destroy an interloper! 40 gold, yes!
Victory tastes so sweet... Like a milkshake. No, maybe more like a bar of chocolate.
My power is overwhelming! And yet, I did not die horribly at the end of the turn.

Lore[]

In Curse of Naxxramas

The archlich known as Kel’Thuzad sits at the seat of power within Naxxramas, coordinating the normally mindless Scourge into a fighting force for the Lich King. In his mortal days, Kel’Thuzad was once a powerful human mage and high-ranking member of the Kirin Tor, working under the great Archmage Antonidas, leader of the Kirin Tor at the time. The Kirin Tor had a wealth of secrets and knowledge at their disposal, and Kel’Thuzad spent countless hours devouring every bit of knowledge he could get his hands on—even the darkest and most unthinkable of arcane arts, such as necromancy. He became increasingly more reclusive and shunned by his peers the further he delved into forbidden magic.
The Lich King sought out Azeroth’s most powerful and ambitious individuals to bend to his will, sending out a mental summons to those he thought could easily be swayed by the promise of power. Kel’Thuzad was the first to answer the Lich King’s call. He saw the power the Lich King held over the undead and desired such power for his own, so he offered his services as a mage to the Lich King in whatever manner he desired. After a long, tortured journey to the frozen wastes of Northrend, Kel’Thuzad knelt at the feet of the Lich King and offered him not just his loyalty, but his soul as well.
"As my lieutenant, you will gain knowledge and magic to surpass your most ambitious dreams. But in return, living or dead, you will serve me for the rest of your days. If you betray me, I shall make you into one of my mindless ones, and you will serve me still.”
The Lich King’s words were both a threat and a promise. Kel’Thuzad would become his lieutenant, carrying out the Lich King’s whims, but in return he would gain power beyond his wildest dreams. Kel’Thuzad accepted these terms… as if he had much of a choice in the matter.[4]

Wowpedia iconThis section uses content from Wowpedia.
Kel'Thuzad was once a human mage of the Kirin Tor. He went on to become the founder of the Cult of the Damned and one of the principal agents of the Lich King responsible for the spreading of the plague of undeath across Lordaeron. After bringing the plague to Lordaeron, he was slain by the paladin Arthas. When Arthas became a death knight, he resurrected Kel'Thuzad as a lich so he could summon Archimonde the Defiler into Azeroth. Following Arthas' departure for Northrend, Kel'Thuzad was left to command the Scourge of Lordaeron from his necropolis, Naxxramas. Following his first defeat, he and his necropolis moved to Northrend.

Trivia[]

  • Kel'Thuzad only has custom replies for the nine classic heroes. He does not reply to alternate heroes, so the match just opens with Kel'Thuzad's "We finally meet" followed by the hero's opening remark.
