Blackrock Depths - Lower, Healer Guide

Posted 5 months, 3 weeks ago for patch 1.13 by Preston.

This page covers healer-focused strategies for the Blackrock Depths - Lower 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 52-60.

While it's technically possible to access all of Blackrock Depths at one time, most players opt to do one of two sections. The Lower or Detention Block section is the first of the two.

This section allows players to obtain the Shadowforge Key by completing the Dark Iron Legacy quest. The key is used to unlock doors to access other parts of Blackrock Depths.
