In this dungeon, you cannot block or evade the attacks of enemies, however their attacks against you can still glance, despite the nightmare tooltips saying otherwise! Here is an example of a nice glance based build that you can use in this dungeon. This dungeon is very difficult to tank compared to many of the other dungeons.
The bosses in this dungeon typically have ranged attacks. While it is possible to melee DPS here, it is not recommended unless you are very experienced.
This dungeon is one of the most difficult dungeons to heal through, especially the third boss. Leeching is recommended along with the Reap and Sew ability. The Backup Drone and Greater Good abilities may also prove very useful here.
Squalid Hekaturgist
Motes of Aten
This fight requires players to be on the move constantly. There are 4 pink orbs (Motes of Aten) that keep rotating counter clock-wise. After changing position 4 times, they will all float to the middle of the arena, then back out and start rotating again. Timing is the key here. If they come near you, you will be silenced and probably die.
Heka Blast
A PbAOE attack which will be cast at the tank’s feet. It will follow the tank around until triggered, thus it is advised that the other members of the group are not inside the circle (as shown below) when it triggers as it will probably kill anyone who is not the tank.
Doctor Klein & Dimensional Reaper
This is the first real challenge in this dungeon. When Klein shows up, a Dimensional Reaper will show up at the same time, and it will cast Unnatural Selection onto Klein, who then gains a 90% damage reduction shield. The Reaper must be dealt with before moving on to Klein.
Open the Void
Orbs will come out of a portal on either the left or right side of the bridge. These orbs are the same as the ones faced in the previous boss encounter, and they will silence and probably kill anyone who gets too close to them. You should therefore stand on the opposite side of the bridge to avoid them as they float by. Be careful not to go too far to either side, though, as you can fall off the bridge.
Swell of Mutation
Klein will summon a small wave on either his left or right side, shortly after he has done this, the wave will dash towards the players and deal enough damage to kill anyone who is not tanking. Like with the orbs, you should go to the opposite side of the bridge to avoid being killed. As the fight goes on, Klein may cast multiple waves in rapid succession of one another, in which case they will be cast on alternating sides.
Dreaming Shroud
This is an extreme Heal and DPS check. The healer needs Reap and Sew and everyone must select the tank as their defensive target. The tank will be unable to act or move for the duration ability, and therefore it is entirely up to the healer and the DPS to keep the tank alive. Buffs such as Deadly Aim, Breaching Shot and Short Fuse are best saved for this attack as Reap and Sew converts a percentage of your damage into healing to your defensive target. Prior to this ability being cast, a blink of purple light will emit from Klein and the tank, thus acting like a warning signal.
Wave of Mutation
Once Dreaming Shroud is over, Klein will begin to cast this. Everyone, except the tank, needs to go back and stand on the broken pillar. The wave will one-shot anyone caught in it. The tank must stand about 8 metres away from Klein and use Spiral of Death to teleport through the wave as it approaches, and thus reach Klein instantly. The DPS and healer may come down from the pillar once the wave has crashed into it and vanished.
Phase 1
Once the Dimensional Reaper is dead, it will cast Heka Blast, but this time it will not follow the tank’s feet. In order to avoid it causing trouble, the tank should stand on either the left or right side of the bridge so that he or she may simply cross over to the other side of the bridge thus being able to tank Klein and avoid the blast at the same time.
The tank should go in first and attack Doctor Klein a few times, then use Chaotic Pull to drag the Dimensional Reaper down, you can then easily aggro both of them, and prevent either of them from attacking other members of your team.
Profane in Membrane and Spray and Pray are Klein’s normal attacks, keep an eye out for the occasional Open the Void and Swell of Mutation and dodge those as needed.
Whenever there is a Purple Flash on you and Klein, it means he is about to cast Dreaming Shroud. You can use Martial Discipline to mitigate some of the damage by glancing.
Afterwards, Klein will immediately begin casting Wave of Mutation, you then need to back up about 8 meters and wait for Klein to cast the wave. Once he does this, you should spam Spiral of Death until the teleport succeeds. Once you reach him, he needs to be impaired to stop him from casting Open the Void and Swell of Mutation simultaneously, which would result in a wipe.
Keep the tank as your defensive target. Kill the Dimensional Reaper first, then switch your attention to Klein. You should also keep an eye out for Open the Void and Swell of Mutation. It is recommended to save Breaching Shot, Deadly Aim and other buffs for when Klein casts Dreaming Shroud on the tank as this will increase the chances of the tank surviving.
When Wave of Mutation is cast, you can either use a Nullity Sphere or simply run back to the broken pillar and jump onto it in order to avoid being killed by the wave. There is filth on the broken pillar, but you need to be on top of it once the wave hits, or else it will kill you.
Phase 2
When the Dimensional Reaper spawns again, it means you are entering this phase. Klein might cast Dreaming Shroud again depending on your DPS, but if he does the procedure will be the same as the previous time he did this.
When Doctor Klein’s HP goes below 240 000, he will flee.This will mark the end of the boss fight, and your loot bag will appear.
Orochi Dead Ops
Before engaging this trio, the group should decide on an order in which to kill them. The most common ways are Right-Middle-Left, or the other way around. Faction marks may be used in order to make it easier to distinguish between the various targets as they move around.
Closedown
This will hinder the target it hits and greatly reduce their movement speed for a while.
Frag
A big AoE grenade will be cast on the tank, and a smaller AoE grenade will be cast on one of the other team members, who that will be is random. The tank should dodge out of the large AoE grenade area.
Phase 1
Phase 2
Once two of the three Orochi Dead Ops are actually dead, the last one will become enraged. During this stage it will hit harder, keep casting grenades and be completely immune to all impairs. It will also have a new ability named Full Clip.
Full Clip
A long range column attack which deals a very high amount of damage.
Dimensional Arachnid
Black Bile
A randomly targeted AoE which places filth on the ground, simply dodge out of its way and stay out of the filth pool that spawns in its place.
When the encounter begins, five Research Assistants will spawn and gradually increase the Boss’ damage output. It is useless to kill them as they simply respawn, so focus the boss at all times.
The Colossus, Melothat
This is a relatively easy encounter as well, but you need to be on the lookout for the Wretched Receptacle adds, as they have a very high damage output, and unless they are dealt with quickly, they can kill the tank.
Over Kill
Noone must get too close to the boss, this attack will hinder and kill anyone who is not tanking if you get too close. The tank can still attack the boss using melee attacks, but you need to keep some distance at all times.
Gate 1
Aggro the Disembalmed Atenists. Once they are dead, you should wait for the DPS players to break down the first gate. When the Wretched Receptacles come through the open gate, it is recommended to use Helter Skelter to impair them for a few seconds, thus giving the DPS time to kill them. Then head back to the BOSS and attack 5~6 times. After that, you should run to Gate 2, and start to aggro the Orochi Dead Ops. but do not break the second gate just yet. This is important!
When the Orochi Dead Ops is actually dead, the BOSS should be about to, or already be walking towards you. After he roars, two Wretched Receptacles will come from behind him. The tank must aggro them and perhaps also use a secondary impair, like The Art of War to stun them long enough for them to be killed by the DPS. Alternatively, one of the DPS players can bring a hindering ability if you do not have enough available ability slots.
Kill the Disembalmed Atenists first, then break Gate 1, once it is down, kill the Wretched Receptacle as quickly as possible. The Dragon’s Breath flamethrower ability is quite useful here. Once they are dead, go back to the BOSS, and attack it until he becomes enraged. You will hear him roar and his movement speed will be greatly increased. At this point you should back away with the tank and kill the Orochi Dead Ops. DO NOT keep attacking the BOSS when he heads for Gate 1 after his enrage.
After the Orochi Dead Ops is dead, it is recommended to NOT break the second gate just yet. Instead, take care of the adds coming from behind the boss first, then deal with the gate as there will be coming adds from behind it once it is brought down.
Gate 2
After the Wretched Receptacles behind the second gate are dead, go back and start attacking the BOSS again until he becomes enraged. You should then back away until you reach the other side of the second gate. Once the boss is reaches it you should resume attacking it. After some time he will send more adds your way, they should be disposed off before they can kill your tank, potentially causing a wipe. Eventually, two Orochi Dead Ops will spawn behind you, but if the DPS is high enough you will kill the boss before they even reach you.
The Colossus, Melothat & Doctor Klein
Sinkhole
This attack is slightly bigger than the white outlines show, so position yourself at least 2~3 feet from the circle. The filth will hinder and damage you continuously. The attack will also leave a filthy area which persists until Klein begins to buff the colossus.
Phase 1
Until The Colossus, Melothat begins to attack the tank, the DPS and leecher should hold their fire. Once the tank has been able to hit the boss a couple of times the DPS and leecher may safely attack. The left side of the arena will be completely covered in filth at this point, do not step in it. The DPS and the leecher should also keep their distance to the boss as his attack is a cleave and will hit and likely kill anyone who gets too close. The filth on the left side of the arena will disappear when Klein buffs the boss.
When Melothat shows up, use Chaotic Pull to get his attention. Stay close to him, and remember that his attack is a cleave, so you should stand to the right of the entrance. When he casts Sinkhole and places a filth area, move slightly to the left and keep tanking him. Repeat this process every time he casts Sinkhole.
At one point Melothat will stop attacking you, and Klein will cast Unnatural Selection which will buff Melothat. You need to interrupt the ability, which can be done by the tank running along the left side of the arena, which was previously covered in filth, and then running up the stairs to hit Klein two times, then you can jump down to Melothat (refer to the image below for exact locations). The Death From Above rocket launcher ability can help you move faster.
Keep the Tank as your defensive target, Melothat’s Cleave has a very long range, you need to stand as far away as you possibly can while attacking him. If the tank has problems keeping aggro after running up to stop Klein, you should cease fire immediately to allow the tank to grab the boss again.
Same as the DPS, your number one priorities should be staying out of the cleave’s range and keeping the tank alive. If a Wretched Receptacle shows up, you need to attack it as your assault rifle has a very long range. Furthermore, you can slot Giddy Up and use it when the tank runs up to hit Klein.
The Path to Klein and back to Melothat
Phase 2
When Melothat is immobilized for the third time, Klein will show up on the entrance side of the arena and immediately begin casting Wave of Mutation, just like he did when you encountered him earlier as the 2nd boss. The tank needs to use Spiral of Death to teleport through the wave and then impair Klein.
Klein will keep teleporting between the scaffolding side and entrance side periodically until he drops below 223 507 HP. After that, Phase 3 will be initiated.
When Klein is on the scaffolding side, you should focus on bringing down Melothat.
Phase 3
When Klein teleports to the top of the arena and begins casting Ungodly Exhortation, the filth on the scaffolding will disappear. At this point everyone needs to go up to him, however, be careful not to jump onto the scaffolding too early as the filth will kill you.
The tank goes up first and attacks Klein to interrupt him from casting Ungodly Exhortation. After this, two Dimensional Reapers will spawn, and Klein will once again have a 90% damage reduction shield. You need to kill them as quickly as possible to make Klein vulnerable to damage.
You need to aggro both Klein and both his Dimensional Reaper companions. Use Chaotic Pull to drag one of the Dimensional Reapers towards you. This way, you can easily aggro them both. Pulling a reaper down is the only way you can aggro all three at the same time. When a Dimensional Reaper dies, it will cast Heka Blast, so you cannot stand near the other players. If you position yourself wisely, just like during the second boss encounter, however, you can avoid the blast, thus decreasing your chances of dying.
Keep the tank as your defensive target. When the Dimensional Reapers show up, you need kill them first. Usually, you kill the left one first, then the right one, but you should have discussed this prior to starting this fight. Only attack Klein after the reapers are dead. Stand as far back as you can, and DO NOT stand close to the tank as the Dimensional Reapers cast Heka Blast, a large and lethal AoE, upon death. If you stand inside its targeted area you need to dodge out of it as soon as possible, as it will kill you if you stand inside of it when it triggers.
Finally, once both the Dimensional Reapers have been dealt with, kill Klein as quickly as possible.
Same as the DPS, however, as Klein will have a constant damage buff on him that will increase as the fight goes on you might need Reap and Sew if the DPS take too long to kill Klein, or if the tank’s HP gets too low.
