Discipline Priest Healing Sepulcher of the First Ones Raid Guide — Dragonflight 10.2.5

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

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.

In order to provide the most accurate raid guide possible, we teamed up with Viserio, creator of the Raid Timer Spreadsheet which can be found on his Discord

We advise you to use the following Legendary against Vigilant Guardian: The Penitent One.

We recommend belonging to the Venthyr covenant for this boss.

We advise you use the following Soulbind against Vigilant Guardian: Theotar the Mad Duke

Loot Spec for this encounter: Shadow

Abilities to ramp for: Exposed Core and Core Overload

This fight involves multiple phases of consistent damage, each phase more dangerous than the last, with the final phase slowly ramping up in damage until either the boss dies or you do. Assigning a strong ramp toward the end of the fight is ideal to extend the duration of the encounter. Prior to the final phase, ramping for the Exposed Cores will be a good idea. On Normal or Heroic difficulty, it is possible to end up with nothing to hit during the Exposed Core mechanic, but this should not be the case on Mythic.

We advise you to use the following Legendary against Skolex, the Insatiable Ravener: The Penitent One.

We recommend belonging to the Venthyr covenant for this boss.

We advise you use the following Soulbind against Vigilant Guardian: Theotar the Mad Duke

Loot Spec for this encounter: Any

Abilities to ramp for: Dust Flail during high stacks of Ephemera Dust

As this fight progresses, your raid will gain an ever-increasing number of stacks of Ephemera Dust, which deal ticking damage per stack of said debuff. Periodically during the fight, you are able to reset your stacks via Ravening Burrow. The boss will also often cast Dust Flail which deals damage to the entire raid. Targeting your strongest ramp around the Dust Flail casts when the raid is at high stacks of Ephemera Dust is the priority. After that, fill the rest of your ramps and Radiance casts on other Dust Flails.

Some people may be tempted to ramp for the Burrow itself as, at a first glance, it seems like a good spot to target. However, the damage of the burrow itself is not very high. Its much more important and lucrative to ramp prior to the Burrow during the high stacks as described above.

Spell ID	Spell Name
359778	Ephemera Dust

We advise you to use the following Legendary against Artificer Xy'mox: The Penitent One.

We recommend belonging to the Venthyr covenant for this boss.

We advise you use the following Soulbind against Artificer Xy'mox: Theotar the Mad Duke

Loot Spec for this encounter: Disc/Holy

Abilities to ramp for: Glyph of Relocation and Genesis Supernova

While this fight has fairly constant damage due to Hyperlight Sparknova, the most dangerous damage during the encounter is due to the Glyph of Relocation mechanic and the intermission damage of Genesis Supernova. Due to the fact that the Glyph of Relocation mechanic has forced movement as a part of it, you need to be very exact with your ramp timing so that you have already completed both radiance casts at a minimum, ideally your Schism as well, prior to the pull-in happening. If you do not, you run the risk of your early Atonements falling off before you can cast Evangelism as well as just missing the damage event all together.

Spell ID	Spell Name
362850	Hyperlight Sparknova
362803	Glyph of Relocation
363114	Genesis Supernova

We advise you to use the following Legendary against Dausegne, the Fallen Oracle: The Penitent One.

We recommend belonging to the Venthyr covenant for this boss.

Note: While this fight has very good timings for Kyrian which may provide a higher HPS Ceiling, most mythic progress strategies involve utilizing the mobility of either Door of Shadows or Soulshape to skip some of the damage from Disintegration Halo. If you are doing this fight on a lower difficulty or you feel you can survive without Door of Shadows, you can consider running Kyrian with Clarity of Mind and Pelagos instead.

We advise you use the following Soulbind against Dausegne, the Fallen Oracle: Theotar the Mad Duke

Loot Spec for this encounter: Disc/Holy

Abilities to ramp for: Inevitable Dominion

Inevitable Dominion will be the most important target for your primary ramps on this fight, so ensure you have your strongest CDs available for as many of these casts as possible. After that, both the tank explosion Unleashed Infusion as well as the damage from the Disintegration Halo will be your mini ramp and spare radiance targets.

Spell ID	Spell Name
360959	Staggering Barrage

We advise you to use the following Legendary against Prototype Pantheon: The Penitent One.

We recommend belonging to the Venthyr covenant for this boss.

We advise you use the following Soulbind against Prototype Pantheon: Theotar the Mad Duke

Loot Spec for this encounter: Any

Abilities to ramp for: Windswept Wings and Hand of Destruction

This is a multi-phase fight with the bulk of the damage coming during Phases Two and Three while the Prototype of Absolution is active due to Burden of Sin, which is massive ticking damage on the raid. During Phase One, using a ramp on Windswept Wings is not a terrible idea, but your strong ramps should be saved for Hand of Destruction if possible. If you are struggling to ramp for Hand of Destruction itself, ramp either just before or just after it to ensure the raid is topped off going into it or picked up after the fact.

If running Venthyr, make sure you cast Mindgames on Prototype of Absolution if he is active to ensure that you recieve your Shadow Word: Manipulation stacks as soon as possible as the other bosses don't consistently trigger damage events to consume the debuff.

360687	Runecarver's Deathtouch
361608	Burden of Sin
360295	Necrotic Ritual
360259	Gloom Bolt

We advise you to use the following Legendary against Lihuvim, Principal Architect: The Penitent One.

We recommend belonging to the Venthyr covenant for this boss.

We advise you use the following Soulbind against Lihuvim, Principal Architect: Theotar the Mad Duke

Loot Spec for this encounter: Disc/Holy

Abilities to ramp for: Cosmic Shift or Protoform Radiance

Due to Cosmic Shift involving a small knockback, if you are ramping for it make sure you have completed your hard casts by the time the knockback happens so you are not scrambling after the fact and miss all the damage. For Protoform Radiance, ramp with instants while you run so that you can use Evangelism when the phase starts so your Atonements last for the majority of the damage.

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

We advise you to use the following Legendary against Halondrus the Reclaimer: The Penitent One.

We recommend belonging to the Venthyr covenant for this boss.

Note: If your guild is doing the strategy that involves stopping DPS so that three minute cooldowns may be up for the second Reclaim cast, Kyrian will be competitive with Venthyr.

We advise you use the following Soulbind against Halondrus the Reclaimer: Theotar the Mad Duke

Loot Spec for this encounter: Shadow

Abilities to ramp for: Earthbreaker Missiles, Reclaim, and Eternity Overdrive

Reclaim is the highest period of damage during the encounter during the first few phases, so it remains an obvious choice for strong ramps. You will need to be careful when applying Atonement to your raid via Power Word: Radiance due to how spread out the raid generally is. The Earthbreaker Missiles will be great targets for smaller ramps like mini ramps. Damage ramps up quite a bit in the last phase via Eternity Overdrive and the increased frequency of Ephemeral Burst damage instances, so using cooldowns around a set of missiles in this phase will also pick up a ton of other healing from these mechanics as well.
