The Tarragrue, Healer Guide

Updated 2 months, 3 weeks ago for patch 9.1.0 by Preston. View the change log.

The Tarragrue Dungeon Journal ModelThis page covers a healer-focused strategy for The Tarragrue in Sanctum of Domination in Shadowlands. 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, combat log information, and Dungeon Journal information. I'll continue to update it as-needed.

General Mechanics and Abilities

  • During the trash before this encounter, players have the opportunity to pick up various Anima Powers to aid them, similar to those in Torghast.

Mythic Differences


Healing Notes

Quick Notes, All Difficulties

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.

Debuffs to Track


  • Crushed Armor can cause the tanks to need additional healing, although a tank swap should occur before this is an issue.
  • Unshakeable Dread (dispel, magic) should be dispelled immediately.
  • Grasp of Death causes players to need additional healing over time.


Enrages to Soothe

Useful Addons

DBM Settings

Below are the DBM settings I'll be using for The Tarragrue in Sanctum of Domination. You can set them up however you'd like, but these ones should work well as a starting point. Some settings may be Mythic only.

Boss Mechanic Practice

While not technically an addon, the browser-based minigame Sanctum of Pineapples is a great way to practice Sanctum of Domination boss mechanics in a low-stress environment.
