Talents: You can pick whatever talent you want for the Tier 5 talent.

Notes: Being a first boss, not much is happening here. You can cloak essentially every mechanic should you get into a bad situation. Still, for the most part, as long as you aren’t standing in any ground effects, interrupting nearby adds, and doing boss damage, you’re doing your job.

Make sure to spread ruptures out to the bigger sentry adds to get some extra energy outside of your cooldowns. Marked for Death also is huge here on the adds, giving you a ton of resets.

Talents: You can pick whatever talent you want as your Tier 5 talent.

Notes: This is a fairly simple patchwerk fight. However, we still have some tricks up our sleeves to utilize. The most common strategy for this boss involves interrupting a retch cast with the burrow. To do this, you have to be out of range. Make sure you have your bleeds up before this happens, and you don’t send your cooldowns into the boss right before it happens.

Once the knock-up happens, you can instantly shadowstep to maintain uptime on the boss. Be careful of any poorly timed swirls!

The last couple of things to note is that you can remove the haste debuff from getting hit by a swirl using cloak and be able to feint the knock-up while the boss is traveling. Good luck with your dagger!

Talents: You can pick whatever talent you want as your Tier 5 talent.

Notes: This boss is generally a single-target fight with adds during the intermission. The rings behave the same as the ones on Dausegne, so like before we can use cloak, shadowstep, and door of shadows if we get stuck in a bad spot.

Use cooldowns to avoid missing casts. Depending on your raid timing you want to use it on the Acolyte add durng the intermissions.

Talents: You can pick whatever talent you want as your Tier 5 talent.

Notes: Most of this fight revolves around two main mechanics: the rings and the puddles. The puddles are mostly a tank positioning and focus target situation that your whole raid needs to deal with; however, it’s a different story for the rings.

For the rings, we have three ways of dealing with them. We can shadowstep a target on the other side of the ring (I usually prefer shadowstepping the boss or the add). For venthyr, a well-timed door of shadows can do the trick, but you can also cloak! Cloak is super helpful for the ending rings, as you can cloak and take multiple in quick succession. Make sure you soak the beam with the rest of your raid so you can save your cloak.

Talents: You can pick Subterfuge instead of Master Assassin, and Deeper instead of Marked for Death. Remember that you can choose whatever talent you want for your tier 5 talent.

Notes: This is the first fight to consider necrolord on. You can still play Venthyr and Dusk just like previously, but the cleave from necrolord can be very powerful. In general, phase 2 will be the hardest point in the fight, so make sure to talk to your raid leader about the strategy that you guys are using. If you’re burning one boss in phase 1 and phase 2, then you might consider playing the standard Venthyr build and using the other target as energy regen from the second set of bleeds.

If you’re going for more overall damage, go with necrolord for the cleave. Both Heimir and Marileth are good soulbinds here, and you can even go zoldyck for phase 3 damage if that’s a problem. Feel it out and communicate with your raid leader. This fight, in general, is not a good rogue fight, so making sure you do the damage when it’s needed is way more important than trying to be top of the meters.

In terms of immunities, you can evasion the spears during winds. Make sure you aim towards the middle of the swirl when you do so, however, as dodging is still directional. Cloak should be held for the pull-in from the Denathrius boss, prototype of absolution. Immune right before the explosion goes off to immune the damage and the puddles on the ground for a couple of seconds after.

Talents: You can pick whatever talent you want as your Tier 5 talent.

Notes: Lihuvim can be an interesting boss. It's another excellent example that it's not always good just to do good overall damage but to do damage where it matters. While you're progressing on this fight, you'll most likely be cutting it really close with damage to the schematics because you only have about 15 seconds to kill them. In my opinion, there are two ways to deal with that. The first is to hold your cooldowns specifically for the schematics, which can be awkward with venthyr. However, you can just play as a night fae.

The issue with holding cooldowns for schematics as a Venthyr is that it can be challenging to get any cooldown usages on the boss if you have to save for every schematic, causing a lot of missed casts. Ideally, you wouldn't need to do this and can just use it on cooldown on the boss, but in general, boss damage isn't much of a concern.

With night fae, holding sepsis is a lot less of a loss comparatively, and you can use vendetta on cooldown, allowing you to get a vendetta on the boss between every add phase much more effortless. Play around with it and see what your raid needs. The decision of when to use your cooldown can vary depending on when the rest of your raid uses their cooldowns.

Immunity-wise, there isn't much for us. Cloak can reduce the damage of the intermission pulses, but usually isn't needed. In general, Cloak is more of a reactive defensive if you get caught in a bad spot.

Save shadowstep for the intermissions to get to the add instantly, and have a charge ready for the pushback from the boss to stack back up quickly.

Halondrus

Talents: You can pick whatever talent you want as your Tier 5 talent.

Notes: Halondrus is a raw single-target fight, so you want to pick the Venthyr covenant and pump all the way. There isn’t much to say here; if you get a bomb make sure you communicate where you’re dropping it so your partner has an easy time getting to it.

You can use cloak to dispel yourself with the slow-field. Make sure you do it in front of the orb spawners to slow the orbs on the way in. In phase 3, save cloak to hit the cluster of orbs away or run through the boss to get to the other side. Cloak immunes the damage of everything except the earthbreaker missiles, so use it accordingly.

Anduin Wrynn

Single Target / Cleave

Talents: You can pick whatever talent you want as your Tier 5 talent.

Notes: This is by far the worst fight for rogues in the raid. Our damage is simply not competitive on this fight, so we need to focus on what we can do! In phase 2, you can very easily shadowstep and kick an add if required. Make sure also to use blind/kidney shot to keep them from casting. If you are going down into the Kingsmourne Hungers phase, make sure you use any cooldowns on the big add, as this is your priority as a single target class. Otherwise, you’re on the boss or the lich king.

Immunity-wise, there isn’t much to do here. Cheat can be used to immune hopelessness in phase 3, but it’s a niche use at best.

Also, do not shadowstep with blasphemy, as it doesn’t truly ‘teleport’ you. The blasphemy will come in contact with anyone between you and your target.

Talents: You can pick whatever talent you want as your Tier 5 talent.

Notes: This is a raw two-target fight, and thus we see the first fight with Necrolord as a recommendation! Remember not to overcap charges of Serrated Bone Spike, but hold a charge for the add to get a reset.

Cloak can save you from a sticky situation but usually doesn’t see too much use. Just make sure to bait swirls well and pump damage. Use feint during swarms if you get low, and save your healthstone/health potion.

Talents: You can pick whatever talent you want as your Tier 5 talent.

Notes: This single target fight is very straightforward, you just want to keep using your cds every minute on the boss, maintaining high uptime. If the quasars come close to melee, you can use a rupture on them to snipe energy back, or use fan of knives for slightly more damage.

The Jailer

Single Target
15
25

50

Talents: You can pick whatever talent you want as your Tier 5 talent.

Notes: For the Jailer it’s a fairly straight forward single target fight, but there are some things to watch out for.

Phase 1:

In phase 1 you will want to cloak the chains right at the start to make sure you get your full opener off. This will let cloak come back up in time for the lineup with mind control lines and the Line of sight right before phase 2, should you need it.

Phase 2:

This phase is the easiest of the fight, you should aim to try and cloak the Torment+Slam overlap that happens about halfway through the phase to live that damage. Remember that cloaking early drops the torment puddle early, allowing you to move on top of others if needed with no problem.

Phase 3:

For this phase, make sure to hold your cooldowns at the start until you get your buff stacks back from the Azerite soak after the first set of mechanics. This is important to help push your damage up as your cooldowns last into the first set of adds. Use your cooldowns as they come up following normal rules after that until the boss dies.

For general tips, feint works on basically everything in the fight, and you can almost use it on cooldown for a lot of mechanics. After the nerfs at the end of 9.2, most of the damage from torments and tank slams are ignorable, but if for some reason you aren’t full health, make sure to pop a defensive as you need.

Sanctum of Domination

The Tarragrue

Single Target
15
25
30
35

50

The best powers to use on Tarragrue in terms of DPS, are Huddled Carvings, Elethium Weights, Potent Acid Gland and Lumbering Form (or alternatively Erratic Howl or Tremorbeast Heart)

This fight is pretty simple. You can cloak one of the three explosions during the intermission, so you have to be in the safe zone twice and then cloak one of them.

Make sure to pay attention to the green beams coming from your teammates and also make sure to pick up the orbs on the floor for extra DPS.

Eye of the Jailer

Single Target / Cleave
15
25
30
35

50

You can use Shadowstep to always appear on the southwest part of the boss every single time. You can also use it to dodge the beam consistently without having to use cloak on it.

You also want to make sure to always keep your dots up on the boss and the add that gets chained in. Not only does it help you with your overall damage, but it also helps to funnel your damage to the boss. So it’s a win-win.

You can use cloak right before applying a new buff to help the healers when you’re getting too many stacks. This can also help by cleansing your stacks and then swapping sides if your side is pumping too hard. However, I wouldn’t recommend it as there is a potential for failure and wiping the entire raid.

If you split the raid in 2, you can dot up the second add you’re not assigned to first before using the chain to jump to the other side to your own add. As long as you don’t spend more than 10s on the wrong side, you should be safe and will not receive a debuff.

The Nine

Single Target / Cleave
15
25
30
35
40
45
50

This boss might seem like a good AoE/cleave fight, however the actual boss, Skyja, takes up the majority of the fight by herself. Thus it is not recommended to use AoE talents on this boss, it is however, crucial that you keep garrote / rupture on both of the big adds in the beginning and even when Skyja comes down. However, it is not as important to use garrote / rupture on the small add that you can interrupt.

You can use cloak to get rid of the frost debuff but this is not recommended as the healers usually have a dispel rotation and if you decide to use cloak you might mess it up.

Remnant of Ner'zhul

Single Target / Cleave
15
25
30
35

45
50

This boss is generally a single target fight, however, you should be using garrote / rupture on the balls before they activate. This is the same concept as using garrote / rupture on the inactive bosses on Council because it helps you funnel energy to the actual boss as well. However, do note if you don't get good value out of it (80%+ of the duration of the garrote/rupture), then it’s better to just fully focus your damage on the boss.

The balls do not reset Serrated Bone Spike or give energy refunds from Venomous Wounds, so applying bleeds to the balls a bit late is not a great idea.

Soulrender Dormazain

Single Target / AoE
15
25
30
35

50

Soulrender is mainly a single target fight, however, it does have some big add waves every now and then which gets killed in less than 20 seconds. Playing Poison Bomb instead of Crimson Tempest is perfectly viable if you do not like the gameplay of Crimson Tempest.

Depending on your tactic, you should be looking to use your major cooldowns on the boss whenever they are available. You don't want to save them for the adds as our cooldowns don’t really benefit us in AoE situations.

Use 1 garrote and 2 ruptures on the adds, and use Fan of Knives to generate combo points (as long as 4+ targets are within range), but you mainly want to keep pumping the boss with Envenoms and remember to maintain CT while the adds are up.

Painsmith Raznal

Single Target
15
25
30
35
40
45
50

The biggest thing to note about Painsmith is that nothing else matters more than actually surviving during the fight. Always prioritize mechanics over DPS because a dead DPS does no DPS.

Try to apply a rupture on the ball that you’re focusing on and keep in mind that they do reset your serrated bone spikes. On top of that they also give energy back with Venomous Wounds, so it's worth to use Venomous Wounds on the balls.

During the intermission, if you want to min-max your DPS, you should try to maintain 100% uptime on Alacrity by using FoK near the balls and you also want to use Slice and Dice to proc Alacrity. You want to do this several times during the intermission.

Disclaimer: This is very min-maxy and it's not recommended if it affects your performance during the intermission and if it causes you to die or proc cheat death.

Some people think about using Crimson Tempest on Painsmith, but it's not worth it because you only focus the boss, or a single ball throughout the entire fight. The adds that spawn after the intermission are alive for 3-8 seconds which is not enough to justify using Crimson Tempest.

Guardian of the First Ones

Single Target
15
25
30
35

50

Guardian is the only pure single target fight in sanctum of domination and as such is the only fight where we can use Blindside/Deeper Stratagem on. This changes your way of thinking, the opener and the actual rotation of the spec to some extent, so if you’re not comfortable with it, feel free to stick to Elaborate Planning and Vigor.

Cloak can be used to help tanks soak the Obliterate cast. You can use one cloak to soak both casts, once every 2 minutes, or every other pillar.

Fatescribe Roh-Kalo

Single Target / Cleave
15
25
30
35
40
45
50

This fight is heavy on the mechanics, so try to always focus on the mechanics first. You might be forced to stop doing DPS, so it doesn’t really matter.

You can use Poison Bomb if you want, but it's overall less DPS because you will not be maximizing your damage around the adds during the main phases or during the intermission. However, Poison Bomb is really good if you’re struggling with boss damage or if your add damage is already through the roof.

Make sure to use cloak if you get the Call of Eternity mechanic on you, because it will completely remove the circle as well as the bomb that spawns from it.

Kel'Thuzad

Most guilds during progression likes to bring Balance Druids inside of the Phylactery, however it is also very common for rogues to be assigned to go in as well. This does not change our talent choices, but it is important to understand how the phylactery works.

Generally, Kel’Thuzad is an annoying boss with many damage stops, so it's usually best to just save your cooldowns for the Remnant in the Phylactery.

If your guild does the slow strat which means that you hold DPS, you should use your cooldowns every phase and once inside of the Phylactery as well. However, if you have enough DPS you don't necessarily need to use cooldowns on the very last phylactery but you could use them on Kel’Thuzad with lust instead. Try to play accordingly to your DPS but If you notice that you’re lacking damage inside of the Phylactery you should use your cooldowns.

In order to min-max damage, you need to DPS the adds as much as possible. The first Frost Blast of every phase will also revive the dead adds, which means it’s your time to shine. Try to apply Crimson Tempest on as many targets as possible and use garrote and rupture on one of the adds and then just spam Fan of Knives / Envenom on the boss.

I suggest using Dashing Scoundrel because your poisons will actually do a lot of damage and as long as you have enough energy regen from your bleeds / dashing and maintain Crimson Tempest, you will be doing a massive amounts of damage (especially with the frost set).

Make sure to prioritize the tank adds instead of the boss because it helps your team when you interrupt them and on top of that it also helps your overall damage.

Sylvanas Windrunner

Single Target / Cleave

Some people have asked me if Crimson Tempest would be a good choice on Sylvanas, and I always tell them that it's not a good choice. Phase 1 is generally just single target with 3 arrow sets and 2 big add waves that dies in less than 10 seconds. Phase 2 is more heavy on the adds, but even then you’ll be spending most of your time running or hitting Sylvanas. Phase 3 is strictly single target and with the Dashing legendary you should never use Crimson Tempest on single target fights. Just stick to Poison Bomb, not only is it the superior talent, it is also much easier to play with because it's a completely passive talent.

Phase 3 is the most important part of the fight, so make sure to read up on all mechanics before you attempt it. You can check out our guide on the method website here. Generally, your job is to do as much damage as possible on the boss without ignoring the mechanics. You should be looking to maximize your uptime on the boss because a lot of our damage comes from bleeds, poisons and close to the boss. The more time you spend out of range, the less damage you will do. I will include cooldown usage tips below so you can maximize your damage during all 3 phases.

You want to use Cloak right before the arrows chain the players because it will remove your debuffs and you won’t take any damage from the chains or the pulsing AoE from the players. Cloak of Shadows is a very powerful during phase 1 because you can completely ignore the arrow mechanic. If you do this correctly you will be able to stand outside of the stacked raid group, use Cloak and then jump to a set of arrows and start melting them down. 

Cooldown usage for Sylvanas:

Phase 1:

You should use all of your cooldowns during your opener including your potion.

You can sync your next Flagellation + Vendetta / Vanish casts by holding Flagellation, as you won’t be getting a third cast of Flagellation during the first phase.

Phase 2:

If you get Benevolent Faerie from a Night Fae priest, you should always look to use cooldowns on both Sylvanas burns. This also stands true if the add packs get absolutely melted and your cooldowns are wasted, however the second burn will be slightly more inefficient and won’t benefit from the entire Vendetta cast.

If you do not get Benevolent Faerie and the adds don’t die instantly, you should be using your first set of cooldowns during phase 2 on the Summoner on the first platform. Your second set of cooldowns, including Flagellation and Vendetta / Vanish, should be used on the second burn. Remember to use your potion with your first set of cooldowns.

Phase 3:

Generally,  you want to use all of your cooldowns whenever they are available, but make sure to sync Flagellation and Vendetta together for the bloodlust burn on the last platform.

You also want to make sure to track the Veil of Darkness cast because you don't want to use your cooldowns just as its happening because they would go to waste. If your Vendetta is up and ready and the Veil is happening in less than 10 seconds, it’s safe to just hold it until the Veil cast is over.

Use your potion with the cooldowns during bloodlust.
