Sire Denathrius, Healer Guide
Updated 1 month, 1 week ago for patch 9.2.7 by Preston. View the change log.
This page covers a healer-focused strategy for Sire Denathrius in Castle Nathria 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.
