Talents: You can pick Slipstream instead of Shimmer.

Notes: This is a pretty straightforward boss. Make sure to save blinks to reach a safe spot when the AoE damage on the raid starts.

Make sure to use Barrier and Blink to move out from the raid if a bomb targets you and you need to go out and come back quickly.

Talents: You can pick Arcane Echo instead of Resonance, and Time Anomaly instead of Overpowered

Notes: Make sure to save Blink for Retch when you need to move with the raid to another position.

IMPORTANT: Make sure to use Alter Time or Barrier when you are the furthest player out for Dust Blast, it will deal heavy damage, and you might outrange your healers, so make sure you don’t end up dying.

Artificer Xy'mox

Talents: You can pick Slipstream instead of Shimmer

Notes: You want to use your Barrier as often as possible. There is a lot of raid damage, especially when you spread to bait the Stasis Trap and from boss Lighting.

IMPORTANT: Make sure to save a kick for the adds during the intermission, which happens at 75% and 50% health. A couple of adds will spawn, and Xy Acolyte is your priority target. Try to save a kick Xy Spellslinger. Debilitating Ray can be deadly if it's not kicked.

It can be extremely helpful to line Radiant Spark and Touch of the Magi on 1 Acolyte because it will splash to everything else.

Dausegne

Talents: You can pick Slipstream instead of Shimmer

Notes: During the fight, the boss will spawn an add that needs to be burst down.

IMPORTANT: make sure to save Blink, Door of Shadows, or Soulshape for the Disintegration Halo Double ring Overlap.

During the encounter, the boss will create a shield on herself with a Siphoned Barrier, and it is crucial to burst down the barrier as fast as possible because it will do heavy raid-wide damage.

Make sure to save Alter time, and have Barrier or Mirror Images ready for the shield. Having Radiant Spark and Touch of the Magi with Rune of Power Ready to burst down Siphoned Barrier will be beneficial.

Prototype Pantheon

2T Cleave / 4T Cleave
15

50

Talents: You can pick Slipstream instead of Shimmer

Notes: In this encounter, you will be fighting 2 targets most of the time. However, in the last phase, you will fight all 4 bosses simultaneously.

Make sure to save Blink \ Soulshape \ Door of shadows to move around the room if targeted by Night Hunter. The Ritualist and the Seed on Mythic are affected by a Shield, and you will need to break the shield with Night Hunter.

Keep in mind that the ritualist adds are a priority during the encounter.

IMPORTANT: Use your barrier as much as possible because this encounter is heavy with raid damage, and your healers will most likely be busy healing the seeds.

Do everything in your toolkit to survive Windswept Wings, and make sure to save Alter time for Hand of Destruction to stand far out and spread properly.

Kick Anima Bolt and Gloom Bolt as much as possible.

Lihuvim

Single Target / Target Swapping

Talents: You can pick Slipstream instead of Shimmer

Notes: Make sure to save blink, door of shadows, or soul shape to move around the room if you need to move out for Motes or if you need to clear the motes with the Bomb.

There will be heavy damage during the intermission, and you can save Alter time to heal yourself back to full HP during the add phase.

On Mythic, there is a new mechanic called Alignment Shift, which means, unlike Heroic and Normal, that only pushes you back, you will also get pulled in on mythic difficulty. So, make sure to save blink or alter time to get back to your assigned group to deal with Alignment Shift.

IMPORTANT: Alignment Shift can either knock you back or pull you in, depending on which one you get. You want to save blink or alter time to deal with it accordingly to get back to your assigned group to stack with your friends for Alignment Shift.

Halondrus

Single Target

50

Talents: You can pick Arcane Echo instead of Resonance, and Time Anomaly instead of Overpowered

Notes: During this encounter, your movement and positioning is key.

This is one of these encounters where you kinda have to “play it for yourself and get the feeling for “

But there are some things I want to emphasize.

The BEST ADVICE I can give to you is always to make sure that you are ahead of the boss during the intermission. You never want to find yourself in a position where you are chasing the boss, especially as a bomb holder.

Incantation of Swiftness is a REALLY nice QoL if you ever need a burst of movement during the intermission. Like Heroic, Crushing Prism should be placed in a good spot to try and slow the Motes.

Reclamation Form can be extremely deadly if you are not at full HP. It is super important that you keep yourself healthy with Barrier / Alter time / Mirror Images since it deals HEAVY raid-wide damage, and your healers might be far away from you or healing other players. Alter time is probably the best thing to deal with Reclamation Form.

IMPORTANT: On Mythic, if you are assigned to handle a bomb, you can see it as playing “Hot Potato“ the less time the bomb is on the ground, the better.

The bomb has a 30 seconds timer on it. While picking up the bomb, you will get a burst of damage and a debuff for 32 seconds, preventing you from picking up the bomb again.

Make sure to have a good amount of health before you pick up a bomb because if Earthbreaker Missiles are happening while you are picking up a bomb with low HP, you might be in danger.

During the intermission, you always want to be ahead of the boss, but make sure not to get knocked off the platform when the boss uses Detonation. If you find yourself with no blink available, alter time can be used to get yourself back into position.

Anduin Wrynn

Single Target / Adds

Talents: You can pick Slipstream instead of Shimmer

Notes: Help your raid soak Befouled Barrier (deadly if you are not at full HP!)

Hopebreaker, Heavy raid-wide damage, make sure to save some a defensive for that, Shield, Mirror Images, Alter time. Blasphemy - make sure to find the opposite color as fast as possible, be CAREFUL with blink because it can trigger an explosion if you interact with someone who has the same color. Monstrous Soul has to be focused and burst down from 35%.

IMPORTANT: When you go into the Kingsmourne Hungers phase, you will leave a reflection of yourself upstairs that needs to be killed once you are done with the adds downstairs, so make sure not to over burst the reflections when you are upstairs and your friends are downstairs for Kingsmourne Hungers.

Alter time can be highly effective because the group downstairs will take heavy raid damage during Kingsmourne Hungers.

Dragon's Breath, Frost Nova, and Ring of Frost can be used if the small adds are getting too close to the center and you want to keep them CC'ed.

Blasphemy will be applied once or twice before the boss dies ( depending on your raid DPS ). You can Ice Block the explosion before the debuff goes off to let more people clear their Blasphemy debuff in the glowing bubble in the center. If you block the Blasphemy debuff, make sure to spread because you will deal a small explosion around you, and you need to be spread from someone else that is immuning Blasphemy so you won't die from the debuff.

Empowered Hopebreaker during the last phase can be EXTREMELY BRUTAL. Make sure to use everything you can to stay alive such as Greater invis, Kyrian Phial, Hearthstone, and Healing Potion.

Lords of Dread

2T Cleave + 1 Add

Talents: You can pick Slipstream instead of Shimmer

Notes: Standard 2 Target cleave fight, once the boss reaches 100 energy, he will start casting Unto Darkness, which deals heavy raid-wide damage, so you might want to look at your health during the cast.

The boss takes extra damage during Unto Darkness, and it might be worth holding a cooldown for that. It should be 45 seconds into the pull.

IMPORTANT: Alter time is vital in this fight when Unto Darkness happens or when you have Cloud of Carrion on you. Greater invisibility is also a good choice.

Rygelon

Talents: You can pick Slipstream instead of Shimmer

Notes: This fight is all about killing the stars at the right time. Some things to keep in mind, you can only hit Dark Matter if you went inside a star and you are in the "delirium phase," so make sure to damage it as much as you can while you are inside. Also, make sure that you get out of the phase in a safe spot so you won't knock your friends away from the platform.

IMPORTANT: make sure to use blink \ door of shadows \ soul shape to reach the point you are assigned to for the intermission so you won't die from the Massive Bang. When you are inside the downstairs phase after killing the dark matter, there will be heavy raid-wide damage, so make sure to use whatever you have to stay alive, including Barrier, Images, etc.

If you are assigned to soak a core, use a defensive cooldown.

Talents: You can pick Slipstream instead of Shimmer

Notes: Alter time can be used to Negate Chains of Oppression.

Make sure to line of sight for Domination.

Torment can be highly deadly early on, so make sure to line up your Barrier with every torment set.

Make sure to look out for Decimator, so you don't end up falling down in a hole. Whenever you find yourself in a bad position or baiting a bad Decimator, alter time or blink can help you get back into position.

IMPORTANT: So, unlike Heroic and Normal, there will be a set 6 bombs in p1 instead of 3. Make sure to position correctly and react to the bomb you are assigned to. Make sure to position yourself properly if you are assigned to heal the boss with Surging Azerite.

World Shatterer can be deadly if you are not at full health, so keep an eye out.

Sanctum of Domination

Pretty straight forward entry boss. Make sure to save blinks for the mist-phase to avoid running and losing a lot of damage.

IMPORTANT: If you somehow end up without blinks make sure to fireblast or arcane explosion while moving.

With prodigy you will have your cooldowns up roughly for every phase, If you are venthyr you will have it with ease, but non-venthyrs might need some good clearcasting RNG.

IMPORTANT: If AP comes up late into the add-phase, you might gain more by saving it as the mob will probably die before touch expires. However, this is something you need to judge as a player. You can blink over the beam however the hitbox and visual is not representative, therefore I would recommend you to use alter time, blink away from the beam, then alter back once the beam has passed your alter time location.

Make sure to let your tanks know that you are not hitting all targets with barrage because it can definitely hit your single target damage heavily if you only hit barrage on 1 target due to how resonance works.

IMPORTANT: Make sure to hit all mobs with orb. In P1 you can get full arcane charges if you aim it properly and this will increase your DPS significantly. If you have good clearcasting RNG, you can get 2nd arcane power off before the shield.

Remnant of Ner'zhul

IMPORTANT: Slipstream is a life-savior. If you are not familiar with slipstream then work on becoming more familiar with it, because this boss has so many knockbacks and movements in general that sometimes you simply won't be able to cast any spells.

You will have rune + touch for add waves and AP for the boss. One thing that was quite tricky was using touch correctly. See if the branded mob dies before Touch of the Magi expires so you don't waste it. It can sometimes be better to just use Touch of the Magi on the boss and have it cleave onto the branded targets and nearby adds.

IMPORTANT: If you are snapping the chains, you can alter time before snapping the chain and instantly alter back. You can also use mirror images before you even take the chain because it will give you the 20% DR for all 3 hits. Alternatively you can also use greater invisibility before the chain breaks.

Very good encounter for arcane mages. You have a lot of upfront damage, and while the intermission happens you can do a lot of quick AoE damage to the adds with arcane explosion and arcane barrage.

IMPORTANT:  You can blink through the spike-wall.

Guardian of the First Ones

Single Target

The Sludgefist encounter without the damage amplification. It's a pretty straight forward fight. You always want to use alter for the intermissions and use blinks to get around and charge the cores.

IMPORTANT: Defensively you have a good skill set for this boss. Always use alter time BEFORE any purging protocol hits. It is better to try and greed alter time a bit, since the first cast of protocol deals the least damage,  you want to avoid big personals on that hit. Therefore ideally, you just face tank the first hit with barrier and mirror images. Mirror images will continue to grant DR for the next 2 hits as well, and then you can rotate alter time and ice block for the bigger hits. As arcane you also have greater Invisibility, but remember the DR only lasts for 3 seconds after you come out of stealth, so use it just before the cast goes off.

Make sure to wait with Arcane Power until you know that you don't have to help with runes. If you are assigned to do a rune then obviously do the mechanic first and then use Arcane Power. There are not that many mechanics in this fight but nearly every mechanic requires heavy movement and will screw you over if you are in your burst windows, so pay attention to Big-wigs/DBM timers.

IMPORTANT: Save alter time until you get the circle, in which case you blink out with the circle and alter back. You can also iceblock and remove the bomb from the encounter. Ice blocking the bomb will not damage your allies and I definitely recommend you to do so if you have bombs overlapping with beams.

Make sure to see if you can snipe low health targets with ruby. Also avoid using radiant spark if you know you have to target swap to glacial spikes. 

IMPORTANT: Alter time is a good ability to use for the soaks, but you can also solo ice block the soak which would negate a lot of raid-damage.

Arcane explosions does a lot of damage to the arrows. However unlike fire and frost, you will lose all your boss damage if you move too far from the boss, so position yourself wisely so that you hit as many targets as possible and the boss most importantly. Obviously if you struggle with the far out arrows you will have to blink out and AoE those.

IMPORTANT: Make sure to have harmony stacked before any add waves and arrows. Slipstream is something to consider as well, as there is a lot of movement which makes it hard to consume clearcasting on missiles.

Alter Time is good for dropping pools and hiding behind pillars and then snapping back to the raid. 

Alter time is also exceptional for picking up the lantern. What you can do is alter time, pick up the lantern, grant vision to your whole raid, then snap back with alter time.

Huntsman Altimor

You can Polymorph the hounds, and let them sit in the CC to get stacks.

This will depend on your Phase 1 DPS entirely. If you have strong DPS in Phase 1, you will have touch of the magi up just before you go over and kill the Shades. This means that you can use touch on the boss, ~3s before you move to the hounds, and start pumping into the touch, which will then explode once the hounds are gathered and you can then switch to spamming arcane explosion into barrage.

You can play the bombardment legendary here. However if tuning changes and the shade boss is more important, then I would strongly advise going back to Temporal Warp.

Use Arcane power on pull and go ham on the adds. Make sure to interrupt the occultist on pull to get all mobs stacked.

Despite using Arcane Power on pull, you can still do meaningful damage to the cloak of flames with rune and touch of the magi, keep in mind that you have to be aware of when the Cloak of Flames happens. The cloak duration is short and you need to use touch of the magi 4 seconds before kaelthas starts the shade cast.

Tip: If you know you are clicking the pedestals at a set timer, make sure to dump all your mana before you channel so that you regain mana passively while channeling.

Night Fae signature spell is really overpowered for carrying seeds. Also, Alter Time is really good for this as well. At the time we tested, the seeds were spawning every 30s, and master of time might actually be a strong option for carrying seeds.

If you are handling the seeds, make sure you have ice block available for the third set of seeds in case you get a ghost spawn on you during the seed handling.

Tip: Mages can iceblock the ghost and not get Mind-controlled. Also mages can ice block out of the traps.

Hungering Destroyer

Alter Time is good when you have to spread with the expunge, Alter Time -> spread -> Alter Time. With the strat we played, slipstream could actually be better, because we positioned very stationary (Vectis style), so we're pretty stacked and we only had to sidestep the beams, which made the use of blink pretty limited.

Tip: You can use ice block to reset stacks of essence sap (mythic only mechanic) and soak again.

Necrolord has a lot of potential on this fight. It requires you to hold Arcane Power on pull, and dump Arcane Power + Necrolord into first adds.

Also, using Arcane power at the normal time (20 seconds into pull), makes it line up perfectly with second set of adds and fourth set of adds.

Tip: Mages can use ice block during the add-spawning cast to stop the add spawn. Its very RNG as it requires the boss to have picked you, but was very handy during progress.

Felt nice with the dances, because you gained mana during the dance. Also, you can use Shifting Power during the dance to reduce your CD’s while nothing is going on.

Sludgefist

Remember that the boss takes double damage when he crashes on a pillar, save your rune and touch for the crash.

Use Rune of Power + Touch of the magi on pull, and use everything on first pillar.

The key rule on Sludgefist is to always have Presence of mind, rune of power and touch of the magi available for every pillar crash.

If you are currently progressing the fight, there might be a case for using Arcane power on the third pillar so that it is up again for the final stretch of the fight. However, with current gear it is very unlikely you will get to that point of the fight and you should therefore use arcane power on fourth pillar with lust.

I tried both full-on single targeting, but also just going full-on pad mode. I found out that it made much more sense for priority damage distribution to go pad mode. Because the adds need to die, it felt very easy to get behind on adds if you didn’t go ham on AoE. Therefore go for the Arcane bombardment legendary and Resonance in talents. Literally act like this is an M+ and spam Arcane Explosion into Arcane Barrage at 4 charges and always hold barrage for 5 seconds if the target is close to 35% for the execute damage.

Don't AoE in intermissions since commandos are immune to AoE when they get low.

Keep in mind that the legendary does very valuable priority damage on the commandos due to the nature of the execute (Mythic).

In Phase 1, just focus on boss damage if your composition has ways to handle the blood prices adds. You can use touch of the magi before add spawns and thus make the mark explode once adds have spawned.

In Phase 2, you can Arcane Explosion on the boss, sword and at least 1 add. So 3 targets at least.

You can use Mirror Image to reduce the blood price damage.

In Phase 3, Alter time is very good for soaking seeds. Go into the seed and pop alter time and once the you get knocked back you can instantly get back to soaking.
