General Information

On this page, you will find tips, tricks, and strategies tailored to your Discipline Priest for each boss of the following raid: Uldir. All our content is updated for World of Warcraft — Dragonflight 10.2.5.


Discipline Priest Boss Advice: Uldir, Halls of Control

In this section, you will find information pertaining to each boss individually in the Uldir raid. It is recommended that you follow the standard talent build found in the Builds, Talents, and Glyphs section of the guide unless otherwise advised, on a per-boss basis. As this is an upcoming raid, the current information is based on beta testing and theorycrafting using Warcraft Logs and will be updated over time. As each boss is hardest on its Mythic difficulty mode, we will first explain the healing strategy for Mythic, followed by a short explanation on what changes in this strategy, if anything, for Heroic.


Talent Cheatsheet for Discipline Priest



In Mythic, this boss has a very spiky damage pattern due to Cudgel of Gore Icon Cudgel of Gore and Hardened Arteries Icon Hardened Arteries. When playing with the suggested talent build, use Power Word: Shield Icon Power Word: Shield, Shadowfiend Icon Shadowfiend, double Power Word: Radiance Icon Power Word: Radiance and Evangelism Icon Evangelism immediately before one of these abilities hits the raid, then follow it up with Schism Icon Schism as the damage hits, as well as Power Word: Solace Icon Power Word: Solace, Penance Icon Penance, and Halo Icon Halo, with Smite Icon Smite as a filler. By the time your Atonement Icon Atonements fall off, the raid should be topped off again, or close to, allowing you to focus on dealing damage to the boss / using single-target heals until the next Cudgel of Gore Icon Cudgel of Gore and Hardened Arteries Icon Hardened Arteries casts. It is important to keep Atonement on those in the raid carrying Plasma Discharge Icon Plasma Discharge, as they are the most at risk of dying.

Alternatively, it is worth mentioning that using Luminous Barrier on this encounter may provide a better cooldown than running Evangelism Icon Evangelism. The intermission during this encounter does not require a cooldown, making Evangelism either unused, or used on a low damage part of the encounter. In addition to this, the people in danger during this fight are those who are carrying Plasma Discharge Icon Plasma Discharge away from the group and cannot stand inside Power Word: Barrier Icon Power Word: Barrier when Cudgel of Gore Icon Cudgel of Gore occurs. Luminous Barrier allows you to provide an absorb to those who are most in danger, while still providing a cooldown for your raid. Running Luminous Barrier also syncs well with Rapture Icon Rapture to handle all of the Cudgel of Gore occurances. You can Rapture the first, Luminous Barrier the second, Rapture again on the third and Luminous Barrier will be back up for the first Cudgel of Gore in the second phase, after the intermission. This process would repeat until the boss is dead.

In Heroic, while the damage intake is still spiky, the intervals between these spikes are larger, since Cudgel of Gore Icon Cudgel of Gore is the only raid damage you need to worry about.



Similar to Taloc, this boss has a very spiky damage pattern, dictated by players passing through Defense Grid Icon Defense Grid, and you should aim to use the Taloc pre-damage strategy when players are about to go through. While it is likely possible that you can have a huge amount of players going through at once while using all raid cooldowns, the most likely scenario in Mythic is that you will be sending small teams every ~20 seconds, because of dangerous adds that spawn when players go through. As a Discipline Priest, you will want to keep a close eye on the spawned add. If they are not interrupted, they will cast Clinging Corruption Icon Clinging Corruption and the raid will require additional healing.

In Heroic, damage is lower and the spawned adds are much less dangerous than the Mythic ones, allowing more people to pass through at each time. In case your guild's strategy involves using multiple raid cooldowns while a lot of people go through, you will want to consider saving your cooldowns for those windows.

Talent Choice:

  • Level 15: Schism Icon Schism
  • Level 25: Angelic Feather Icon Angelic Feather
  • Level 30: Power Word: Solace Icon Power Word: Solace
  • Level 35: Shining Force Icon Shining Force
  • Level 40: Sins of the Many Icon Sins of the Many
  • Level 45: Halo Icon Halo
  • Level 50: Evangelism Icon Evangelism

Fetid Devourer

In Mythic, we will need to handle Malodorous Miasma Icon Malodorous Miasma / Putrid Paroxysm Icon Putrid Paroxysm spreading to nearby people whenever they tick, which forces a heavy spread on the raid at all times. Given your raid spreads properly, you will just need to focus healing on targets with the debuff, who will be taking large amounts of damage. It is recommended to maintain Atonement on those players and weave in damage. Because of the single target healing required, using Penance Icon Penance defensively more than normal is a definite option.

In Heroic Malodorous Miasma Icon Malodorous Miasma / Putrid Paroxysm Icon Putrid Paroxysm do not spread, making positioning requirements much more relaxed.


Zek'voz, Herald of N'Zoth

Most of the incoming unavoidable damage in this fight will come from Surging Darkness Icon Surging Darkness, which hits the raid over a prolonged period of time and requires you to heal while moving. To handle healing this ability, you will want to ensure you use Rapture Icon Rapture as needed, or apply Atonement Icon Atonements with Power Word: Radiance Icon Power Word: Radiance, followed up by Penance Icon Penance and Power Word: Solace Icon Power Word: Solace while on the run. Due to Eye Beam Icon Eye Beam and Roiling Deceit Icon Roiling Deceit (which, if not handled correctly, will cause a lot of raid damage through Shadow Nova Icon Shadow Nova), the probability of unexpected near-lethal damage is high. Keeping cooldowns at the ready is important to help the raid recover. Also, in the last phase, we are a decent choice for the Corruptor's Pact Icon Corruptor's Pact buff, as we can unload what cooldowns we have available before being mind-controlled. Despite this, other healers may be better fit for this buff, as Discipline is gated by Power Word: Radiance having a recharge time, thus limiting our ability to convert mana into healing.

In Heroic, Eye Beam Icon Eye Beam / Roiling Deceit Icon Roiling Deceit are never active at the same time and are disabled upon entering a certain boss health threshold. This makes the fight much easier, but does not change our overall healing strategy.



This fight is all about controlling stacks of Lingering Infection Icon Lingering Infection. As time goes by, these will grow and make casts of Contagion Icon Contagion more deadly, especially as it is likely the raid will be affected by Immunosuppression Icon Immunosuppression at the same time. As Contagion is cast about every 20 seconds, this is a great fight for Discipline, as it lines up well with the Power Word: Radiance Icon Power Word: Radiance recharge of 20 seconds, meaning you can line up one Power Word: Radiance per Contagion cast.

In Heroic, Lingering Infection Icon Lingering Infection does not have the extra effects that cause the encounter to snowball out of control after players hit 6 stacks and above, thus allowing for a more relaxed positioning and control of the stacks.


Zul, Reborn

Other than Dark Revelation Icon Dark Revelation bursts, damage starts low and ramps up throughout this encounter. Be aware that damage will heavily ramp up post 40% boss health, due to Locus of Corruption Icon Locus of Corruption applying a lot of Corrupted Blood Icon Corrupted Blood stacks to everyone in the raid. Erupting Darkness Icon Erupting Darkness can also cause massive, unexpected raid damage. Due to this, it is important to keep in mind that Absorbed in Darkness Icon Absorbed in Darkness soakers and players with Unleashed Shadow Icon Unleashed Shadow will require heavy single target healing as well throughout all the fight. Maintain Atonement Icon Atonement on them to provide healing and be ready to defensively Penance Icon Penance those players as needed.

In Heroic you only need to deal with Corrupted Blood Icon Corrupted Blood after the boss hits 40% health and there is only one Dark Revelation Icon Dark Revelation to deal with every minute, instead of the two in Mythic. This vastly reduces the healing requirements of the encounter and allows you to save most of your Mana for the end of the encounter.


Mythrax the Unraveler

During this encounter, the raid is spread out at least 5 yards from each other due to Oblivion Sphere Icon Oblivion Sphere, meaning Power Word: Radiance Icon Power Word: Radiance should still have a decent effectiveness. Players will have their maximum health reduced by Annihilation Icon Annihilation, which gives us less time to heal before deaths occur. This being said, there will be spikes of raid damage happening regularly from Imminent Ruin Icon Imminent Ruin and Crashing Oblivion Icon Crashing Oblivion that we can help heal efficiently with our cooldown spells, as explained on Taloc.

In Heroic, the dangerous healing mechanics are mostly the same as Mythic, and thus the same strategy should be used.



Most of the damage taken in this fight comes from Reorigination Blast Icon Reorigination Blast, Putrid Blood Icon Putrid Blood and Explosive Corruption Icon Explosive Corruption. While the healing gets much more intense towards the end, when you can no longer remove Putrid Blood stacks with Blood Feast Icon Blood Feast, this is a very long, intense fight, that will strain your Mana to the limit and require excellent cooldown management.

In Heroic, Explosive Corruption Icon Explosive Corruption is much less threatening, but you still need to contend with the other damage sources, which can be handled with the same strategy as Mythic.
