Assassination Rogue DPS Sepulcher of the First Ones Raid Guide — Shadowlands 9.2.5

On this page, you will find Assassination Rogue 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 Assassination Rogue and what you can do to deal with each fight as best as possible.

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.

As your Legendary choice largely depends on whether or not you have already gained access to the Assassination Rogue 4-Piece bonus or not, we will not be including Legendary recommendations for specific bosses. If a specific Legendary is of particular usefulness, it will be noted in the Tips section instead. For a quick glance at what Legendary to play for which Covenant, please refer to our Legendary section instead.

Unless noted otherwise, we highly recommend playing Venthyr as your Covenant on every single fight. The only exceptions to this are multi-target encounters where playing Necrolord might lead to higher overall damage at the cost of single-target damage output.

Talent choices largely depend on your Covenant choice and whether or not you already have the 4-piece set bonus. Please refer to our talent page for more information.
