Most mob packs have roughly equal health and the pet mobs summoned during combat don't Bolster so there aren't too many places you can go wrong.

You can pull the Rift Guardians separately from the oozes around them.

The Fragmented Voidlings that fall from the sky throughout the instance do not bolster.

You shouldn't still be tanking the any Famished Broken below 30% HP unless you've got a stun up. You will die, your priest will die, bad things will happen.

On L'ura, don't move out of a Fragment of Despair soak to dodge a Volcano. You should have more than enough room to dodge without leaving the circle but if push comes to shove you take that volcano.

The boss deals 100% more damage when standing in any void zone. This makes Decimate incredibly dangerous. Decimate is on a timer, the boss cannot be standing in the void during the cast.

The Void Sludges will explode if they reach the boss, dealing heavy AoE damage. They also drop void all over the area so it's in your best interest to kill them as quickly as possible. They can be stunned, slowed and rooted and you should do so where possible.

Every so often a random non-healer player will be targeted by Umbral Shift, moving them to the Void Realm (spooky). While in the void you'll need to kill the Dark Aberrations and each will give you 10 void energy on death. When you reach 100 you'll get an extra action button that'll stun the boss and triple his damage taken for 20 seconds.

Anyone Fixated by the boss needs to run away and avoid getting hit even once. You can run through the void if necessary but keep it to a minimum.

Debuff

Void Traps tend to cluster near the boss. Avoid them, and avoid the Ravaging Darkness which is a cone AoE from Darkfang. He'll cast it after teleporting to you and you should be able to avoid it without taking even a single tick of damage.

Spread out around the room to minimize the amount of movement you have to do and to prevent Umbral Flanking from hitting more than one person.

Dread Screech is a priority interrupt. Missing even one can easily be a wipe.

Tip: Dread Screech is almost always cast after it leaps. Be ready to use ranged interrupts.

Take care that you don't wander into a nearby trash pack.

Void Traps can be cleared with Anti-Magic shield or an immunity if you're in a tough spot.

You must interrupt Howling Dark and Eternal Twilight after breaking the shield.

Tank the boss toward one side of the arena to minimize the danger of the Entropic Force push back. You'll need to interrupt a Dark Blast cast in order to move him since he doesn't use any melee attacks otherwise.

It takes several minutes for the collapsing void encircling the area to reach the boss. You're toast much earlier than that though since you'll need some room to move around to kill off Void Lashings. The fight combines that sustained DPS check with a burst DPS check in the add spawns that must die as soon as possible.

Two Shadowguard Voidtenders are summoned when the boss hits 100 energy and they'll put an impenetrable bubble on the boss while they live. You have 10 seconds to kill both and interrupt the Eternal Twilight cast.

The Rift Wardens will each cast one Fragment of Despair which forms a purple circle on the ground that you must stand in to soak. The soaker will take moderate damage but if the Fragment is not soaked the entire party will take heavy damage and likely be one shot.

You'll get two waves of Rift Wardens. The first has one, and the second two. After you clear a wave L'ura will be stunned for 12 seconds and take 3x the damage.

Phase 2 is a moderate DPS check though not usually problematic if you got some good damage in during the two Backlashes.

Affix DetailsBolsterBolster

Do not pull multiple trash packs at once, so that the maximum stack size of Bolster stays low

Attempt to DPS the enemies down evenly

However, if there is a priority target, such as the Wrathguard Bladelord in Black Rook Hold, it may still be beneficial to focus fire and kill these targets first

The healer will need to use cooldowns on the tank if possible when an enemy has high stacks of Bolster

BolsteringBolsterBolsterNecrotic WoundNecrotic WoundNecrotic Wound

Do not pull multiple trash packs at once

Use AoE CCs, such as stuns, knockbacks, and slows, to allow the tank to kite effectively at high stacks of Necrotic Wound

During boss fights, a non-tank player with a taunt ability can taunt the boss away from the tank to allow Necrotic Wound to fall off

TyrannicalTyrannical

Black Rook Hold: Smashspite's Brutal Haymaker debuff increases the damage the tank takes by 75%, and may cause Earthshaking Stomp or melee attacks to be fatal

Court of Stars: Advisor Melandrus's Slicing Maelstrom will become unsurvivable with just a few Image of Advisor Melandrus spawns

Darkheart Thicket: Shade of Xavius's Nightmare Bolt may one-shot players without active defensive cooldowns, especially if he gains any stacks of Apocalyptic Empowerment

Halls of Valor: Hyrja's Arcing Bolt and Expel Light abilities may one-shot while she has 4+ stacks of Mystic Empowerment: Thunder or Mystic Empowerment: Holy

Maw of Souls: Ymiron's Dark Slash is extremely powerful under Tyrannical and may require external cooldowns for the tank to survive

Woah the detail! Legitimately this is what I needed right now. I regularly run +10's and above but haven't touched Seat yet. I didn't feel confident enough and didn't want to mess anything up for my group. This is a great guide. I'm gearing up my healer and will use the guides when she's ready to go. Great work.

You know what I am over this dungoen on a keystone, pretty much zero dps can do saprish cause they dont ever disrupt the bird no matter how many times you ask them to. Be warned if you get this dungoen on a high keystone your doomed becuase I havent found a group yet that was able to pull it off with saprish at all due to failure to do mechs. Then when they figure out their incapable of doing it, go into denial that it isnt their fault for not doing mechs, and then rage quit and mess up your key that you worked hard on. Your best bet it to do a guild group seeing as they tend to listen more but pugging it is a nightmare at best. I've had so many keys runined becuase of this dungeon.

WeakAura mentioned on Trash Tab 1 didn't seem to get copied from the original guide so here it is:
