De Other Side, Healer Guide
Updated 1 year, 1 month ago for patch 9.2.7 by Preston. View the change log.
This page covers healer-focused strategies for De Other Side dungeon 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 as well as Dungeon Journal and combat log information. I'll continue to update it as-needed.
