Grobbulus, Healer Guide

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

Grobbulus Dungeon Journal ModelThis page covers a healer-focused strategy for Grobbulus 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.

Grobbulus ModelGeneral Mechanics and Abilities

  • The tanks will be dealing with:
    • The expanding Poison Clouds that appear at the boss' location throughout the encounter, requiring the boss to be moved frequently.
    • The highest threat target should remain in melee range to avoid Slime Stream dealing heavy damage over time to all players.
  • Don't stand in front to avoid Slime Spray.
    • Each player hit spawns a Fallout Slime.
      • Fallout Slime
  • When affected by Mutating Injection (dispel, disease):
    • Move at least 20-yards away from other players, ideally near existing Poison Clouds.
    • When the effect expires or is dispelled, it deals moderate to heavy damage to all players within 20-yards with Mutagen Explosion and leaves behind a Poison Cloud.
    • Mutating Injection (dispel, disease) occurs more frequently as the encounter goes on.
  • After 9-minutes (12-minutes on 10-Player), Enrages, greatly increasing Attack Speed and Physical damage dealt.

Grobbulus 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)
    • There's nothing to pre-heal before, but keeping heal over time effects active on players with Mutating Injection (dispel, disease) can be beneficial.
  • Other things to watch for
    • This encounter has high potential for large spikes of damage on many players.
