Blackwater Behemoth, Healer Guide
Posted 1 year, 6 months ago for patch 8.2.5 by Preston.
This page covers a healer-focused strategy for Blackwater Behemoth in The Eternal Palace. 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, logs information, and Dungeon Journal information. I'll continue to update it as-needed.
