Grimrail Depot, Healer Guide

Updated 1 day, 2 hours ago for patch 6.2.4 and Timewalking by Preston. View the change log.

This page covers healer-focused strategies for the Grimrail Depot dungeon in Warlords of Draenor. 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 and combat log information. I'll continue to update it as-needed.

 Nitrogg Thundertower Dungeon Journal Model Nitrogg Thundertower

Stage One - Nitrogg

This stage begins the encounter and ends when he reaches 60% health.

This stage begins when Nitrogg reaches 60% health and ends when the Assault Cannon is killed.

  • Nitrogg is no longer attackable and instead his Assault Cannon must be killed.
    • While the Assault Cannon can be attacked directly, the best method for killing it is to use the Blackrock Turret Munition's Homing Shell, detailed below.
  • Immediatelly following Reloading, if targeted by Suppressive Fire, break line of sight to avoid the moderate damage over time.
  • Avoid the sections of the train car covered in Slag Blast fire.
  • Players on the outer train car platforms are slowly pushed backwards. It is possible to fall off the side of the train car.
  • Blackrock Reinforcements steadily join the encounter.

    • Grom'kar Grenadier

Stage Three - The Final Stand
