Grobbulus, Healer Guide

Posted 5 months, 2 weeks ago for patch 1.13.6 by Preston.

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

  • The tanks will be dealing with the expanding Poison Clouds that appear at the boss' location throughout the encounter, likely forcing the boss to be moved.
    • Additionally, if the top threat target isn't in melee range, Slime Stream deals fatal damage to all players.
  • Don't stand in front of the boss to avoid Slime Spray.
    • Each player hit spawns a Fallout Slime.
      • Fallout Slime
        • Stay at least 15-yards away to avoid the damage over time from Disease Cloud.
  • Targets random players with Mutating Injection (dispel, disease), which leaves behind a Poison Cloud when it expires or is dispelled.
    • Players should move to a designated area, or near existing Poison Clouds, before being dispelled.
  • After 12-minutes, Enrages, gaining increased physical damage dealt and attack speed.

Resistance Levels

  • Players generally won't make use of any additional resistances on this encounter.

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.

  • As long as Poison Clouds are managed properly there won't be a significant amount of healing during this encounter.
