General Information

On this page, you will find tips, tricks, and strategies tailored to your Blood Death Knight for each boss of the following raid: Sepulcher of the First Ones. All our content is updated for World of Warcraft — Shadowlands 9.2.5.

1.

Introduction

During Shadowlands Season 4, Castle Nathria, Sanctum of Domination, and Sepulcher of the First Ones will each spend time being featured as a Fated Raid. During these times encounters within the specific raid will include an additional mechanic and items will drop at increased item levels. If you would like to learn more general information about the Fated Raids system as a whole, please see our overview below. Otherwise, continue to use this page for specialization-specific tips.

On this page, you will find Blood Death Knight-specific information to deal with each boss in the Sepulcher of the First Ones raid.

This page assumes that you already understand most of the mechanics of each encounter. These can be found on the full raid guide, so what is contained here are details specifically tailored toward Blood Death Knight and what you can do to deal with each fight as best as possible.

A note on Level 50 talents: The recommendations will show either Purgatory Icon Purgatory or Red Thirst Icon Red Thirst for all bosses. Purgatory Icon Purgatory will be used when learning the encounter and the tank damage patterns. Once you are comfortable with those, Red Thirst Icon Red Thirst will yield better results.
