Vectis, Healer Guide
Updated 2 years, 7 months ago for patch 8.1 by Preston. View the change log.
This page covers a healer-focused strategy for Vectis in Uldir. 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 fight as well as Dungeon Journal information. I'll continue to update it as-needed.
General Mechanics and Abilities
Normal and Heroic
This fight alternates between two stages during which you'll fight Vectis directly and dodge various blood mechanics. I wasn't able to figure out exactly what causes a phase switch, but I'll update the guide once it's known.
