Demonology Warlock DPS Sepulcher of the First Ones Raid Guide — Dragonflight 10.2.5

In this section, you will find information and guidance for each boss individually in Sepulcher of the First Ones as a Demonology Warlock. These are not complete encounter guides, but rather provide specific tips for any Demonology Warlock on each boss.

During the Dragonflight Pre-Patch, Castle Nathria, Sanctum of Domination, and Sepulcher of the First Ones will be simultaneously featured as Fated Raids. During this time encounters within each 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.

Disclaimer: The tips below are based on Shadowlands Season 4, not Dragonflight changes.

We advise you to use the following Legendary against Vigilant Guardian: Wilfred's Sigil of Superior Summoning.

This is a three-phase boss with adds and a single-target burn.

During Phase 1 pool resources for the Pre-Fabricated Sentry. If priority damage is needed consider pooling Wild Imps off small targets to focus the Sentry with a bigger Tyrant, instead of using Implosion. Demonic Gateway can be used to facilitate the bomb mechanic.

In Phase 2 Demonic Circle can trivialise the Matter Dissolution mechanic.

Try to enter Phase 3 with all cooldowns since it is either kill or be killed.

For more information, please refer to our Vigilant Guardian guide.

We advise you to use the following Legendary against Skolex, the Insatiable Ravener: Wilfred's Sigil of Superior Summoning.

This is a single-target fight with periodic wide movements.

Pay attention to Retch and try to not have your cooldowns rolling during that ability. Demonic Circle can be used to both dodge Retch or nullify the knockup from the Ravening Burrow later on.

For more information, please refer to our Skolex, the Insatiable Ravener guide.

We advise you to use the following Legendary against Artificer Xy'mox: Wilfred's Sigil of Superior Summoning.

This is a two-phase boss with mostly single-target and few adds in Phase 2.

Demonic Circle can bypass the Genesis Rings mechanic entirely, reducing the need for additional movements.

Enter Phase 2 with a Tyrant ready to focus the Acolytes down.

We advise you to use the following Legendary against Dausegne, the Fallen Oracle: Wilfred's Sigil of Superior Summoning.

This is a single-target fight with occasional cleave.

Demonic Circle can be used to nullify Disintegration Halo damage. Demonic Gateway can also be used to help the raid navigate across the platform during these movements.

Save cooldowns for when the boss casts Inevitable Dominion.

For more information, please refer to our Dausegne, the Fallen Oracle guide.

We advise you to use the following Legendary against Prototype Pantheon: Wilfred's Sigil of Superior Summoning.

This is a council fight with 2 to 4 targets in the fight.

Use Demonic Gateway and/or Demonic Circle to get in range and DPS Necrotic Ritualists and to counter the Pinning Volley.

Curse of Tongues can be used to slow down the frequency of Gloom Bolts.

Demonic Circle should be used to disengage from Hand of Destruction.

We advise you to use the following Legendary against Lihuvim, Principal Architect: Wilfred's Sigil of Superior Summoning.

This is a two-phase single-target boss with several adds in the second phase.

Save cooldowns to burn down the designated add before it activates going into Phase 2.

As usual Demonic Gateway can be used to facilitate maneuvering across the arena.

For more information, please refer to our Lihuvim, Principal Architect guide.

We advise you to use the following Legendary against Halondrus the Reclaimer: Wilfred's Sigil of Superior Summoning.

This is a three-phase, single-target boss.

In Phase 1 it is extremely important to prioritise soaking orbs. Save cooldowns for when the boss reaches 100 Energy and has the Reclaim shield.

During intermissions stay ahead of the boss to avoid any unwanted knockback.

Across the whole fight Demonic Circle can be used to bypass Planetcracker Beam safely.

For more information, please refer to our Halondrus the Reclaimer guide.

We advise you to use the following Legendary against Anduin Wrynn: Implosive Potential.

In the Shadow Realm focus down the Anduin's Despair add while passively cleaving down the small Anduin's Doubt adds.

Save cooldowns for when the boss reaches 100 Willpower as it will cast a powerful buff on the whole raid entering the first intermission.

In Phase 2 use Curse of Tongues on Grim Reflection adds to reduce the amount of interrupts needed.

For more information, please refer to our Anduin Wrynn guide.

We advise you to use the following Legendary against Lords of Dread: Implosive Potential.

This is a two-target boss fight.

Make sure to apply Curse of Tongues on Manifest Shadows add only after it is fully healed.

Save cooldowns for when Mal'Ganis reaches 100 energy and casts Unto Darkness. During this phase make sure to use Implosion.

For more information, please refer to our Lords of Dread guide.

We advise you to use the following Legendary against Rygelon: Wilfred's Sigil of Superior Summoning.

This is a two-phase fight with multiple adds in the first and boss in the second.

In Phase 1 Demonology is not the best choice to handle adds due to the subsequent downtime associated with melee pets, however Demonbolt from Demonic Core procs and even Implosion can be used in a pinch to burst these down.

For more information, please refer to our Rygelon guide.

We advise you to use the following Legendary against The Jailer: Wilfred's Sigil of Superior Summoning.

This is a three-phase boss fight.

Movement tools such as Demonic Circle and Demonic Gateway can help with handling the line-of-sight requirement for Relentless Domination although these are better used to handle the Chains of Oppression pull.

Demonic Circle in Phase 2 can be used to avoid a knock out of the platform after a Decimator.

In phase 3 use active damage mitigation when soaking Desolation.

Demonic Circle and Demonic Gateway can be used to handle the Chains of Anguish mechanic.

Do not step into Defile. Please.

Use Curse of Tongues on the Torment add and focus it down.

For more information, please refer to our The Jailer guide.
