How to Beat Kel'Thuzad

Kel'Thuzad is the final boss of Naxxramas, zone 12 of 12, “The Scourge Invasion”. On the community clock checked for 0.110.0, Kel'Thuzad arrives at 20:00. The run has already shown four earlier bosses. You unlock the next zone only by killing this one, on this class. Surviving until the timestamp is not the unlock.

Arrival

Defeat C'Thun in Gates of Ahn'Qiraj on this class. The earlier clock, for context, is on the Naxxramas page.

Mechanics that are actually published

Every boss on this route, including Kel'Thuzad, enrages below 30% health. That is the shared rule. We are not attaching a private ability list. Hit points stay omitted: the 0.112.5 pass did not produce one boss health value to cite, and the older 0.103.1 figures were not re-measured.

Spend the enrage window on movement and on whatever your capstone already does to targets under 30% health. Execute-style talents, Warrior’s Mortal Strike route, and Hunter’s Aimed Shot resets are examples. A new card grabbed at 31% health will not come online in time.

The last zone on this class. Come with a finished tree and a build that already beat C’Thun. Kel’Thuzad is the end of the route, not a new puzzle. If the earlier 20:00 bosses are killing you, more talent experience beats a fresh guide.

Builds that fit this zone

• Warlock build. Dots on the boss, demons between you and the enrage. If the pet plan and the dot plan are both half-finished, you have neither.
• Mage build. Explosions clear adds. The boss still has to be kited under 30% health. Blink through the boss, not into a corner.
• Hunter build. Pets do not replace a boss pattern. Keep distance when the final boss drops under 30% health.

If Kel'Thuzad is killing you, another clear of the previous zone is usually more talent experience than a new class. Then come back with the same capstone finished.
