Unholy Death Knight DPS Uldir Raid Guide — Dragonflight 10.2.5

In this section you will find information pertaining to each boss individually in the Uldir raid. It is recommended 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 each boss is hardest on its Mythic difficulty mode, we will first explain the strategy for Mythic, followed by a short explanation on what changes in this strategy, if anything, for Heroic.

It is very important that you do not stand between the tank and Taloc when he is casting Cudgel of Gore. Do not follow the boss after it casts Cudgel of Gore to prevent excess damage. If you are targetted with Plasma Discharge use Anti-Magic Shell to prevent some of the damage or to stack pools of blood on top of each other to save space. If you are using the Unholy Frenzy build then it is important that you do not cast Unholy Frenzy close to when Taloc casts Cudgel of Gore due to you not being able to hit Taloc with melee attacks during the charge. Due to the Coalesced Bloods being very important targets during the intermission it is recommended that you cast Outbreak onto all adds that spawn. Make sure that if you are using Grip of the Dead then cast Death and Decay so it covers as much area in front of your group as possible.

M.O.T.H.E.R is another 3-phase fight, split into three rectangular boss rooms. Each room is on a timer, based on when the boss enters. All players must pass through the barrier and reach the end to defeat M.O.T.H.E.R. before they are incinerated.

Wind Tunnel conjures a gust of wind in the room, which pushes you towards zones of fire. It is recommended that you save Death's Advance for Wind Tunnel in order to maximize uptime on MOTHER.

The main fight mechanic revolves around Defense Grid. Everytime players cross into the next room, the entire raid takes damage and adds spawn, based on how many players crossed the threshold. Make sure to preemptively cast Anti-Magic Shell for the crossovers in order to minimize the damage that you will take.

The adds are top priority in this encounter when you have crossed through the Defense Grid. These adds are why you should be using the talent Asphyxiate in order to help to stun the adds that spawn.

When the boss enters the last room, she will gain a 100% damage taken debuff. Because of this, you have to make sure that your DPS cooldowns and second potion are ready before entering this final room. It is worth saving Army of the Dead for this part of the fight if you do not expect the fight to last more than 8 minutes.

Fetid Devourer's main DPS feature is its vulnerability phase. The boss takes 50% increased damage when it is below 50% health, so it is worth saving cooldowns for when this happens such as Army of the Dead for this phase if you do not expect the fight to last more than 8 minutes.

The main boss casts very few abilities. Rotting Regurgitation is a cone ability targeted at a random player, which must be dodged or you will take a large amount of damage and have Malodorous Miasma applied to you. If you are afflicted with Malodorous Miasma, be it random or through the breath, it will evolve into Putrid Paroxysm, which is another debuff which does substantially more damage in a short duration. If you have this debuff, you should use Anti-Magic Shell to minimize the damage it will do. If Shockwave Stomp lines up with this debuff then you should also use Icebound Fortitude.

Shockwave Stomp (Heroic and up) is a raid-wide knockback, which pushes you backwards a considerable distance. Make sure you watch for this timer before using cooldowns especially Unholy Frenzy.

Two adds will spawn from six waste disposal units at random. It can be worth saving a cooldown such as Dark Transformation to quickly burst down these adds.

This encounter is split into three phases, with a few basic mechanics that persist through the whole fight. The main mechanic is Surging Darkness. This creates three zones of darkness centering where the boss cast the ability. One zone will be safe for every pulse. Make sure you have Wraith Walk ready to react quickly.

Phase One spawns many Silithid Warriors that fixate a target and can be stunned and burned down effortlessly. You should save Dark Transformation and Death and Decay for these adds in order to burst them down quickly.

Lining up your heavy cleave abilities such as Dark Transformation and Death and Decay with the Plague Amalgams is very important. Sitting on these cooldowns in order to maximize their cleave is very important. Save Anti-Magic Shell for large hits of Contagion.

Heroic: Lingering Infection does not have the extra effects, however it still does almost the same amount of damage as your Anti-Magic Shell meaning you can protect nearly all the incoming damage from this effect.

Your job in this encounter as a Unholy Death Knight is to help control the adds that spawn. There are three sets of adds that spawn in Phase One. Nazmani Bloodhexer spawn in packs of two and must remain separated. Focus these first and kill them quickly. The second Bloodhexer may possibly cast Congeal Blood; the add that spawns from this cast is the only target that takes priority over the two Bloodhexers. Bloodhexers can be hard crowd controlled, knocked back, stunned, and silenced, as well as the add that they spawn. These adds are the ones you will most likely want to use your DPS cooldowns on such as Dark Transformation, and Apocalypse.

Nazmani Crusher is your second priority and Bloodthirsty Crawg are normally just burned down through passive cleave. The Crushers will spawn one at a time and the Crawgs will spawn four at a time. When there are no Nazmani Bloodhexers active, target the Crusher and cleave off of him.

This fight consists of a boss phase and an intermission phase. During the boss phase, just be aware of any Annihilation stacks you have. Clear them if they get too high, or if you are called to clear them using Existence Fragments. You can limit the number of stacks you receive by avoiding casts of Obliteration Blast, which targets a random player and shoots a laser at them, and its intermission counterpart, Obliteration Beam. Wraith Walk is a very useful talent for handling Imminent Ruin in order to get far away from other players. If you are targeted with Imminent Ruin, you should use Anti-Magic Shell in order to prevent some of the damage as you will be away from the group.

At 75% health, the intermission phase begins where Mythrax spawns two N'raqi Destroyers which are separated and need to be burned down quickly. You should also target Visions of Madness that spawn during the intermission and it is worth noting that the talent Asphyxiate can interrupt these adds making it worth talenting into.

• Overview of the fight against G'huun with TL;DR for each role
• Complete list and explanations of G'huun's abilities
• Detailed strategy to beat G'huun with many tips

G'huun is the final boss of the raid. The encounter consists of an upstairs minigame portion, as well as three downstairs phases.

Death Knights in general are a moderate choice for the upstairs minigame, which involves significant mobility abilities. You will not be as good as some other specs at this job however if talented into Wraith Walk and using Death's Advance's active ability effectively, then you can be a good alternative for this job.

Blightspreader Tendril is very important in the first part of the encounter, you should cast Mind Freeze to interrupt Decaying Eruption as close to the completion of the cast. Try to aim your ghoul to hit as many targets as possible with Claw during Dark Transformation.

Before G'huun casts Wave of Corruption, you can preemptively cast Anti-Magic Shell in order to prevent the damage and the application of Putrid Blood. Make sure you turn away from G'huun when he casts Gaze of G'huun to prevent being feared.
