Heigan the Unclean, Healer Guide

Updated 5 months, 1 week ago for patch 3.4.1 by Preston. View the change log.

Heigan the Unclean Dungeon Journal ModelThis page covers a healer-focused strategy for Noth the Plaguebringer in Naxxramas in Wrath of the Lich King. 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, combat log information, and Dungeon Journal information. I'll continue to update it as-needed.

Heigan the Unclean ModelGeneral Mechanics and Abilities

During this encounter, players will be alternating between the two stages on a set timer.

Stage One - Eyes on Heigan

This stage lasts for 90-seconds.

  • Stay more than 30-yards away (usually standing on the raised platform Heigan started on) to avoid the greatly reduced cast speed effect from Spell Disruption.
  • Dispel Decrepit Fever (Decrepit Fever on 10-Player) (disease) quickly, starting with the tanks, to remove the reduced maximum health and moderate damage over time effect.
  • For the duration of this stage, players not on the raised platform will need to avoid Eruption locations.
    • The room is divided into four quadrants, with quadrant one by the entrance players came in and quadrant four by the doorway opposite the entrance.
    • Eruptions occur every 10-seconds in three of the four quandrants.
    • The safe quadrants always follow the same pattern: 1, 2, 3, 4, 3, 2, repeat.

Stage Two - The Unclean

This stage lasts for 45-seconds.

  • Heigan teleports to the raised platform and does not move.
  • Stay more than 21-yards away (the entire area of the raised platform) to avoid Plague Cloud.
  • For the duration of this stage, Eruptions now occur one right after the other, forcing players to constantly move.
    • The safe quadrants follow the same pattern as stage one: 1, 2, 3, 4, 3, 2, repeat.


Heigan the Unclean ModelHealing Notes

Quick Notes, All Difficulties

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 as-needed
  • Pre-heal Before (mainly for heal over time classes)
  • Other things to watch for
    • When possible, keep players near full health so they have a chance to survive being hit by Eruption if they make a mistake.

Heigan the Unclean ModelDebuffs to Track


  • Decrepit Fever (Decrepit Fever on 10-Player) (dispel, disease) Should be dispelled immediately from the tanks, and quickly from other players.
