This page covers healer-focused strategies for the Gnomeregan dungeon. 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 as well as Dungeon Journal information. I'll continue to update it as-needed.

Best for players level 24-34.
