Kel'Thuzad, Healer Guide

Updated 1 month, 4 weeks ago for patch 1.13.6 and Season of Mastery by Preston. View the change log.

Kel'Thuzad Dungeon Journal ModelThis page covers a healer-focused strategy for Kel'Thuzad in Naxxramas. While it's tailored for healers, other roles may also find the information useful. If you have any suggestions or feedback, you can leave a comment below or tweet @PrestonDvorak.

This guide has been updated and maintained based on my own experiences with the encounter, logs information, and Dungeon Journal information. I'll continue to update it as-needed.

General Mechanics and Abilities

Stage One - Minions of the Lich

This stage begins the encounter and ends after ~5-minutes, during which players will fight against Kel'Thuzad's minions.

  • All players should be in the center of the room to avoid pulling additional enemies from the alcoves around the outer edges.
  • Soldier of the Frozen Wastes
    • If they reach any player, deals heavy damage to all players with Dark Blast.
  • Soul Weaver
    • Deals moderate damage to all players and knocks them back with Wail of Souls.
  • Unstoppable Abomination
    • The tanks will be dealing with Mortal Wound, reducing healing received.

Stage Two - The Lich

This stage begins following ~5-minutes in stage one and ends when Kel'Thuzad reaches 40% health.

  • Stay more than 10-yards away from as many players as possible to mitigate chaining damage and effects from some abilities during this stage.
  • Interrupt Frostbolt to prevent the heavy damage dealt to the tank.
  • When affected by Detonate Mana, stay more than 10-yards away from other players to avoid dealing damage to them.
    • This burns 50% of the affected player's mana over 5-seconds.
  • Chains of Kel'Thuzad mind-controls the current tank and four other players, increasing their damage dealt and healing done.
    • Affected players should be crowd controlled immediately. Be prepared to purge healing effects and buffs from Kel'Thuzad.
  • Targets random players with Frost Blast, stunning all players within 10-yards and dealing critical damage over time.
  • Avoid the locations of Void Blast shadow patches.
  • Deals moderate damage to all players with Frostbolt.

Stage Three - Guardians of the Lich

This stage begins when Kel'Thuzad reaches 40% health and ends once he's killed.

  • Kel'Thuzad uses the same abilities as in stage two.
  • Up to five Guardians of Icecrown spawn from the portals in the alcoves at the edge of the room.
    • Guardian of Icecrown
      • Susceptible to Shackle Undead.
        • Only three can be shackled at once or Shackle Shatter breaks all shackles.
      • Gradually gain stacks of Blood Tap, greatly increasing damage dealt.
      • Once Kel'Thuzad is killed, these run away.

Season of Mastery Differences

  • Currently, I'm not aware of any mechanical differences.
  • There are new quests offered by Archmage Tarsis Kir-Moldir just inside Naxxramas, and it was suggested that these could lead to surprises that "have a significant impact" inside and outside Naxxramas.

Resistance Levels

  • All players should use as much Frost Resistance as possible without sacrificing other stats.

Healing Notes

The notes below mostly pertain to progression difficulty, meaning if you out-gear the difficulty you're on or use extra healers they may not apply.

  • Use cooldowns on Frostbolt.
  • Players affected by Frost Blast need immediate healing to keep them alive.
  • Mana can be a problem due to Detonate Mana, making mana management and avoiding overhealing especially important.
