Vigilant Guardian, Healer Guide

Updated 1 month, 3 weeks ago for patch 9.2 by Preston. View the change log.

Vigilant Guardian Dungeon Journal ModelThis page covers a healer-focused strategy for Vigilant Guardian in Sepulcher of the First Ones 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.
