This page covers a healer-focused strategy for Gluth 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.

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.

• Keep players near full health so they can survive Chain Lightning.
• Keep the tanks near full health before Polarity Shift so they can survive the possibility of all healers needing to move.

Debuffs to Track

• There are no particular debuffs to track.
