Unité d'oppression aérienne CT-8 - Junkwatt Depot

Unité d'oppression aérienne CT-8

The Unité d'oppression aérienne CT-8 will be flying over one of the bosses and locations listed above.

You'll want to defeat any boss that does not have the Unité d'oppression aérienne CT-8 flying over it, as it will make the fight harder.
Defeating all the bosses with the Unité d'oppression aérienne CT-8 above it is one of the conditions to activate Hard Mode, which is covered at the very bottom of the guide.

Unité d'oppression aérienne CT-8

Choose a boss that does not have the Unité d'oppression aérienne CT-8 over it.

Salcrass Notable Trash MobsMonstruosité toxiqueVrilles toxiquesConsumer

Vrilles toxiques is cast about every 20 seconds, and will pull all players to the center of the Monstruosité toxique.

It will then immediately cast Consumer
This creates a zone of Gelée dévorante under itself that slowly expands, dealing damage and applying a healing reduction to any player hit. This can be removed using a Disease Dispel.

While Consumer is being channeled, players will be pulled towards the Monstruosité toxique and towards the Gelée dévorante.

Vrilles toxiquesMonstruosité toxiqueVrilles toxiquesGelée dévoranteDésengagementCharge sauvage

Run out of the expanding Gelée dévorante after you get pulled in!

Elémentaire gélatineuxBoulon gélatineux

Players should aim to interrupt Boulon gélatineux when pulled with a Monstruosité toxique as the slow will make running out of the Gelée dévorante much more difficult. The debuff can also be removed with a Poison debuff

Elémentaire gélatineuxs will face a direction and cast Vague de gelée, causing them to charge in that direction dealing high damage to anyone hit and knocking them back.

Make sure to dodge out of the way when Elémentaire gélatineux casts this ability.

Gelée ronge-gnomeGouttelette ronge-gnome

Both of these mobs will cast Jet d’acide, an uninterruptable spell that does minor damage to all players.

The Gouttelette ronge-gnomes have little health and should be cleaved down, as otherwise there will be many casts of Jet d’acide dealing very high damage to players.

Rôdeur toxiqueBrouillard suffocant

One player should be assigned to interrupt the Rôdeur toxique's Brouillard suffocant as having a player stunned for 10 seconds is not ideal.

If no interrupt is available, you can use a Crowd Control or Displacement ability to interrupt the channel.

Salcrass Boss Abilities and StrategySalcrassMonstruosité toxiqueRobot arroseurRobot arroseurSalcrassSubstance visqueuse toxiqueSubstance visqueuse toxiqueRecouvert de substance visqueuse

There is a permanent pool of Substance visqueuse toxique under Salcrass so melee should make sure that they don't enter his hitbox.

While Recouvert de substance visqueuse, players are incapacitated, preventing them from using other actions.

When a player is Recouvert de substance visqueuse, other players should defeat the Goop encasing them.

A player with a Disease dispel can instantly remove Recouvert de substance visqueuse from a player or Squirt Bot.

Robot arroseurRobot arroseurRecouvert de substance visqueuse

When the encounter starts, the Robot arroseurs will activate Pulvérisateur assainissant and slowly walk around Salcrass.

Players who stand in the Pulvérisateur assainissant will be immune to the effects of Substance visqueuse toxique

When a Robot arroseur walks over a pile of Substance visqueuse toxique, the pool of Substance visqueuse toxique will be removed.

There is one Robot arroseur that walks in melee range of the boss and melee can almost permanently follow that Robot arroseur for the entire fight.

SalcrassÉclaboussementRecouvert de substance visqueuseRobot arroseur

Players should safely defeat the Goop that encases the Robot arroseur.

Be careful when defeating the Goop, as while the Robot arroseur is Recouvert de substance visqueuse it does not have the Pulvérisateur assainissant aura.

SalcrassVapeurs toxiques

He will periodically rain pools of Substance visqueuse toxique into the arena, indicated by green swirlies.

About 10 seconds later, he will cast Confluence, drawing all pools of Substance visqueuse toxique directly to him.

Players should make sure that there is no Substance visqueuse toxique pool directly behind them.
Alternatively, they should stand in a Robot arroseur or stand in between a Robot arroseur and the boss.
He will then once again drop more pools of Substance visqueuse toxique into the arena.
10 seconds later, he'll cast Vague toxique, sending out a wave of Substance visqueuse toxique in all directions.
There are no gaps in this ability, so players must be standing in a Robot arroseur or directly behind one.
You can outrange Vague toxique but it requires players to be very far out of range.

Dodge Vague toxique by standing in a Robot arroseur.

Trixie Zap & Naeno Mégavroum Notable Trash MobsNuage de fuméeRobot-ferrailleur lourdRobot-ferrailleur lourdProtocole de désassemblageThey will also cast Gyro-ferraille. After an initial cast, they will activate a Whirlwind effect dealing high damage to all nearby players. Players should make sure to not be in melee range during this time.Robot-ferrailleur lourds will release some Échappement, creating a Nuage de fumée in the area. As it interferes with targeting, tanks should drag the mobs out of the Nuage de fumée.Lastly, Protocole de réparation will be when the Robot-ferrailleur lourd reaches low health. This should be interrupted. Ferrailleuse tête-de-pistonMarteau-pilon

This is a massive armor reduction to your Tank and Tanks should be careful about pulling extra mobs with these.

Mitrailleur tête-de-pistonTir

These mobs will frequently reposition using Course et bastos and there's nothing you can do about it.

They will also toss Grenade à ferraille at the location of players.

Bobine foudroyanteMécano tête-de-piston

They will frequently Coup de bouclier your tank dealing high physical damage.

Make sure to interrupt Suralimenter, a 3 second interruptable cast. If this goes off, all nearby robots will gain 100% haste.

Assign another interrupt for Réparation, a targeted heal that heals for 50% maximum health.

Rampante militariséeCanon à limaille

The Rampante militarisée will face towards a random player and after a short cast, will fire a burst of damage in a small cone.

The other ability that it will use is Bobine foudroyante. This causes the Rampante militarisée to deal high AoE damage to the party and the healer may need to use cooldowns to survive.

Molosse-o-tronMâchoires métalliques

They will also face towards a player and cast K.A.S.S.. Any player that is hit takes damage and has their Haste and movement speed reduced by 50%.

Trixie Zap & Naeno Mégavroum Boss Abilities and StrategyTrixie ZapNaeno Mégavroum

When Naeno Mégavroum is defeated first, Trixie Zap gains Super boost. This increases her Haste by 100%.

When Trixie Zap is defeated first, Naeno Mégavroum gains Turbo Boost. This makes his melee attacks deal high raid damage to all players.

Trixie ZapNaeno MégavroumDémarrage

When Naeno Mégavroum is in the Mechacycle, he will aim in a direction and after 4 seconds, Naeno Mégavroum will cast Pied au plancher launching the Mechacycle across the field in a straight line.

This deals near lethal damage to those hit and knocks them back, so it's important to look at the Mechacycle and move out of the way.

Naeno Mégavroum will then cast Brûlure soudaine creating a Nuage de fumée and casting Pied au plancher again.

After the second Pied au plancher, Naeno Mégavroum will exit the Mechacycle and engage in melee combat.

Naeno Mégavroum

He will cast Accident de la route charging to an area dealing high damage to those in the area.

Tanks will have to watch out for Explose-boulon. This is a frontal cleave that is cast towards the Tank and will likely kill any non-tank.

Nuage de fuméeMéga zapTrixie Zap

Instead, she spam casts Zap électrique, a 2.5 second long cast that will deal a small amount of up front damage, but applies a hard hitting DoT that lasts for 20 seconds.

Players should coordinate interrupts whenever possible, but it's inevitable that some of these casts will go through.

Trixie Zap will also periodically reposition using Glissade électrique.

Trixie ZapMéga zap

This is an 8 second long uninterruptable cast that marks a player.

At the end of the cast, the player will be stunned for 8 seconds and take a very high amount of damage.

To counter this, the marked player should enter the Nuage de fumée, left behind by Naeno Mégavroum, at the last second. This prevents the player from getting Méga zapd.

Roi Gobbamak Notable Trash MobsSaurolisque mordille-osEntaille déchiranteBroyeur ronge-osFêle-crâne

These Troggs will try to Rage increasing damage done by 100%. Try to interrupt this whenever possible.

You can also remove this buff with a Soothe effect.

Chaman ronge-os

Shamans will try to cast Peau de pierre on a nearby target. This reduces their damage taken by 75% and grants immunity to Crowd Control effects.

In addition, they will also try to cast Maléfice avide. If successful, this roots all players for 8 seconds, making it very difficult to dodge other abilities.

Both these abilities should have a kick assigned to them.

Lance-débris ronge-osLancer d’ordures

Occasionally, one of the casts will be Lancer d’ordures which is targeted on the floor as a red swirl.

Malmeneur ronge-osCoup de tête

The most important ability that it casts is Onde de choc.
The Malmeneur ronge-os will face a random direction and cast Onde de choc dealing very high damage to anyone hit.

It's important to kick any Chaman ronge-oss if you pull a Bully, as you need to be able to dodge the Onde de choc

RageGrogneur ronge-osFureur destructrice

They do nothing special but melee hit but will fixate random targets.

Roi Gobbamak Boss Abilities and StrategyViolent coup chargéRoi Gobbamak

Roi Gobbamak will constantly summon Grogneur ronge-oss throughout the entire fight

These troggs deal minor damage but will quickly become overwhelming.

You'll want to use the Stolen Tech in the area to help keep the number of Grogneur ronge-oss low.

Roi GobbamakViolent coup chargé

This deals very high damage that is split among all players near the Tank.

The party should group up during this cast to help the Tank survive.

Every player that is hit by Violent coup chargé will become Charge électriqued dealing a small amount of damage over time.

Players can remove the Charge électrique early by standing next to either the Robot-ferrailleur volé or a Bobine foudroyante volée.

This also activates the Stolen Tech for 20 seconds, which will instantly kill any Grogneur ronge-oss that come near it.

Bring your Charge électrique to activate a piece of Stolen Tech marked above.

Roi GobbamakGrondement

This deals high damage to all players over 5 seconds and causing many Cave-Ins to occur.

Tir rapideCavalier de Mécagone

They will Charge to a target and then start casting Tir rapide.

The Cavalry will quickly kill any player that remains in front of it while slowly rotating in a random direction.

Ranged players can outrange the Tir rapide, but this may cause the Cavalry to charge very far away from the melee.

Troupier mécagonienNano-tranchoirRenormalisatrice mécagonienne

They will alternate between casting Agrandir and Rapetisser.

If Agrandir is successfully cast, it increases the health and damage of the target by 100%. It can be removed by a Magic Purge.

If Rapetisser is successfully cast, that player will deal 99% less damage and healing. Rapetisser can be removed by a Magic Dispel.
Shrunk players can be stepped on by other players, causing them to take near-fatal damage.

Porte-bobine anodisé

Bobine chargée is a 6 second long channel that deals damage every 1.5 seconds for 6 seconds. It can be interrupted.

Exploseur de tank MOD1Unité d'oppression aérienne CT-8

The Tank Buster will cast... a Tank Buster called Laminer.

This deals a large amount of Physical damage every second for 3 seconds to the Tank.

Every hit also stacks the debuff Laminer which makes every hit harder than the last.

Tanks should make sure they have cooldowns active for this ability.

AutodestructionRelais de renfort

This will summon some Fulgurotron X1s into the arena.

The Walkie Shockies are completely immune to damage but can be Crowd Controlled.

These robots will focus random targets, slowly walking towards them and leaving Décharge statique in their wake.

Their energy depletes over time and upon hitting 0 energy, they will Autodestruction.

Druid's Enchevêtrement de masse are particularly good at dealing with the Walkie Shockies.

When you engage the Tank Buster, a Blue Ring will lock players into the Arena and teleport players back inside if they try to leave.

The healer will have to deal with the Exploseur de tank MOD1 casting Décharge fulminante on random targets.

The HK-8 will move around the outskirts of the arena and periodically cast Déflagration de canon towards the center of the arena.
This creates a line of cannon blasts that will nearly one-shot any players hit.

You can have someone follow the movements of the HK-8 to know where the cannon blasts will be showing up.

Dodge the line of Déflagration de canons.

Start positioning to the side of the Arena and after a few seconds, the ring around the edge of the arena will disappear.

The Unité d'oppression aérienne CT-8 will fly to the center of the arena and start casting Rayon d’annihilation dealing light ticking damage to the party.

This will also start a slowly expanding zone, dealing very high damage to anyone who is caught in it.

This forces players towards the Overcharge Station

The first trap that players will encounter is Explosion d’évent.
This trap is located underneath the grated floors and will periodically light up and activate.

Standing on the grates when they activate will cause you to take a high amount of damage and stun you for 2 seconds which may cause you to get by another trap.

Sentry Array

This trap is a rotating set of beams that will teleport you back to the start if you're hit by them.

Classes with Leaps and Jumps will be able to traverse over the Sentry Array.

Sentry Bots

Getting hit by a bot will teleport you back to the start.

The first set of bots will alternate traversing down the left and right side of the platforms.

The second set of bots will rotate around the Overcharge Station.

Dodge the rotating Sentry Array and Explosion d’évents.

The Overcharge Station starts with 100 energy.

Every second that anyone spends hacking will remove 2 energy from the Overcharge Station.

When the Overcharge Station hits 0 energy, the Unité d'oppression aérienne CT-8 will go Détraquée making it fall to the ground and taking triple damage for 30 seconds.

During this time, Étincelles de tempête robotique will fly out of the boss and you should dodge the area of impact.

If the boss is not dead at the end of the 30 second channel, it will fly back up into the air and you'll start at Phase 1 again.

Click on the Overcharge Station to hack it. Make sure to dodge the Sentry Bots!

Chariotte bombeExplosion

This should be interrupted to reduce damage.

Chariotte mécanotrotteurCoup de bec aérien

After the cast finishes, the Chariotte mécanotrotteur will fly to that location dealing damage to anyone remaining in the area.

Simply move out of the zone!

Chariotte fuséeBarrage de fusées

Getting hit by one does moderate damage.

You can use a stun to stop the channel and the Barrage de fusées cast.

Tussle Tonks Boss Abilities and StrategyLe « Tabasseur de platine »Gnomastoc TKC

These bosses do not share a health pool and do not need to die at the same time.

We recommend killing Gnomastoc TKC as soon as possible.

Scie circulaire

There are 4 Piston Smashers located around the room.

Piston Smashers look like giant hammers and will activate when something moves under it.

After being activated, it will smash into the ground after a couple seconds and the PIston Smasher will become permanently deactivated when it hits the Le « Tabasseur de platine ».

Le « Tabasseur de platine »Placage en platine

Each time the Le « Tabasseur de platine » is struck by a Piston Smasher it will remove one stack.

At the start of the fight, the Tank should use their Taunt and bring Le « Tabasseur de platine » underneath 3 total Piston Smashers.

The healer will likely gain healer aggro until the first stack is removed so make sure that the Tank constantly taunts it in the right direction.

Bring the Le « Tabasseur de platine » underneath a Piston Smasher.

Le « Tabasseur de platine »Tranchant tourbillonnant

Players should back away for the short time this ability takes.

The Le « Tabasseur de platine » will also Poser une mines on the ground that you should dodge.

After it impacts the wall, it will be stunned for 10 seconds.

Gnomastoc TKCJets d’écope

This cast slows itself by 60% and the fixated player should run away!

The party will take very high fire damage every second for 10 seconds and the healer should use cooldowns during this time.

If you're directly in front of Gnomastoc TKC during Jets d’écope, you'll take additional damage.

K.U.-J.0. Notable Trash MobsK.U.-J.0.Unité de traitement des déchetsTraitement des déchets

They will cast Rebut enflammé on random target dealing a very light amount of ticking damage.

D.0.G.s will also cast Mâchoires métalliques on your tank.

Déchets vivants

They do nothing special until they reach 1 HP at which point they cast Déchets instables.

This deals a large amount of damage to all players and if too many Déchets vivantss die at the same time, it will likely wipe your party.

You should aim to stagger the Déchets vivants deaths, or Line of Sight the cast.

K.U.-J.0. Boss Abilities and StrategyK.U.-J.0.Bond explosif

Getting hit by an Largage aérien will deal minor damage to anyone in the area and knock them back.

Junk Cubes will become "Heated" when they are hit by some of K.U-J.O.'s abilities.

When a "Heated" Junk Cube tries to become "Heated" for the second time, it will instead become a Ferraille explosive.

This instantly deals damage to anyone nearby and knocks them back.

K.U.-J.0.Bond explosif

He will mark random players and jump to them a couple seconds later.

These players should spread out and more away from Junk Cubes.

Any Junk Cubes hit will become "Heated"

Expulsion de flammes

After a long cast time, K.U.-J.0. will deal very high fire damage to anyone within Line of Sight.

Players can use Junk Cubes or any corner of the Arena to hide from this ability.

This ability will heat all normal Junk Cubes and detonate all Junk Cubes that are already "Heated"

Because of this, it's important to not hide behind Junk Cubes that are "Heated" at the start of the cast.

Hide out of line of sight during Expulsion de flammes

K.U.-J.0.Mâchoire ardente

This deals very high Magic damage every second and must be dispelled.

When dispelled it deals minor damage to the rest of the party.

There is a short grace window until the first tick of the debuff to allow the healer an easier time dispelling.

Machinist's Garden Notable Trash Mobs

The Conveyor Belt will be pushing against you and you'll have to dodge jets of flame.

The first player to make it to the end of the Gauntlet can push a button to disable the flame jets.

It's faster to walk on the edges of the Conveyor Belts as those don't push you in any direction.

Walk against the Conveyor Belts and dodge the fire!

Wave 1 contains 2 Bricoleuse mécagoniennes and 2 G.A.R.D.E.s

Wave 2 contains 2 Robot de défense Mod. Is and 1 Robot de défense Mod. III.

Bricoleuse mécagonienneGiga-torgnole

The more deadly ability is Activation de l’écureuil antipersonnel.

Players who stand in the area will take massive damage but the cast can be stopped with a stun, making the Squirrel despawn harmlessly.

G.A.R.D.E.Mâchoires métalliquesRobot de défense Mod. IArc électrique

This can be Magic Dispelled by a healer.

Robot de défense Mod. IIIArc électrique

Court-circuit will deal damage to all players every 0.5s for 3 seconds.

Explosotron X-80

Everyone should stay away from its front when it casts Impulsion sonique as it silences anyone hit for 8 seconds.

It will also cast Lancement de roquettes hautement explosives dealing high damage to anyone hit by the rockets.

Lastly it will cast Décharge du condensateur
This long channel will periodically deal damage to three-quarters of the area.

The area that is safe will be telegraphed beforehand and players should move to that area.

Look for the faint blue outline for where the Décharge du condensateur will fire.

There will be an alleyway full of Détect-o-bots that you have to make your way through.

Entering the circle of an Détect-o-bot will get you teleported back to the start.

However, entering a Évent à vapeur furtif will prevent a Détect-o-bot from detecting you while in its circle.

Dodge the Détect-o-bots and use the Évent à vapeur furtifs to hide!

Défenseur de l'atelierMécanien mécagonienDéfenseur de l'atelierTronçonneuseMécanien mécagonien

Suralimenter should be prioritized as it increases the haste of all robots by 100%.

Régler should also be kicked as it heals 10% health every 2 seconds.

Machinist's Garden Boss Abilities and StrategyMachiniste en chef ElectrofluxCanon lance-flammes « caché »

If you look at the center statue, you'll see little spouts that pertude after the cast.

These spouts tell you where the Flame Cannons are going to begin.

A few seconds later, the Flame Cannons will fire, locking players in the section of the room that they're currently in.

Getting hit by the Flame Cannon leaves a very high ticking DoT and stacks if you cross multiple lines.

Stay between the Canon lance-flammes « caché » lines!

Canon lance-flammes « caché »Plante anodine

These will focus a random player and channel Floraison explosive.

This deals single target damage until the Plante anodine is dead.

Once it dies, it becomes an Fontaine d’huile and will transform when hit by the next Canon lance-flammes « caché ».

This transforms it into a Flamme ronflante causing many fire patches to dodge near it's corpse.

Flamme ronflantes will never despawn and you'll have more and more fire patches to dodge as the fight goes on.

Discom-BOMBE-ulateur

This will be cast on the location on a random player.

Getting hit will disorient the player for 9 seconds, but it can be magic dispelled.

If this hits your tank, Sparkflux will start to melee hit another target.

La haie qui se taille

This is a bouncing sawblade that will never despawn.

Getting hit will deal a large amount of damage.

King Mechagon Notable Trash MobsChar araignée

These mobs have a frontal cone Impulsion sonique that silences anyone hit for 8 seconds.

They will also Lancement de roquettes hautement explosives.

King Mechagon Boss Abilities and StrategyUnité aérienne R-21/X

While in this mode, he does not melee hit the tank but instead spam casts Impulsion explosive

This does pure magic damage so physical damage mitigation will not work on this portion of the encounter.

Orbe de plasma

Players who get too close will take damage and be knocked back.

However, King Mechagon will periodically move the Orbe de plasmas using Recalibrage.

Recalibraged Orbe de plasmas will deal massive damage in the areas marked, and a smaller amount of damage to players that they pass through.

You can see where each Orb is traveling to by the arrows next to each Orb.

Try to dodge as many as you can!

Dodge the Orbe de plasmas during Recalibrage.

Rayon coupantMégadécharge

In Phase 1, this fires towards the target and pierces them, dealing a large amount of upfront damage and leaving a damage over time effect.

This debuff lasts 12 seconds and increases damage taken from Mégadécharge by 100%. This bonus effect is not important during Phase 1.

Rayon coupant

The Unité aérienne R-21/X will Décollage ! and then channel Rayon coupant for 12 seconds.

This deals high damage to the entire party, but does massive damage to anyone directly under the Rayon coupant.

The Unité aérienne R-21/X will chase a random target during this time.

The Rayon coupant hitbox is very small and melee DPS can continue DPS'ing without taking the extra damage.

Unité aérienne R-21/XCasseur Oméga

The Orbe de plasmas and Recalibrage will still be cast from Phase 1.

The Casseur Oméga is tanked like a regular mob.

Mégadécharge

In Phase 2, Mégadécharge is much wider and has a graphic showing exactly where's its firing.

It is also cast 3 times rapidly in succession, making the !00% bonus damage debuff important to manage during this phase.

Mégadécharge

We recommend that the targeted player do not move, letting everyone else move out of the effect.

It's important that if Mégadécharge is not targeted on you, you move out of the effect to not get the debuff.

If you're hit by a second Mégadécharge during the same set, the second cast will likely be lethal damage without a large damage reduction.

Stand still if targeted by Mégadécharge and let other players dodge!

Magnéto-bras

Players and Orbe de plasmas will be drawn towards the Magnéto-bras for 9 seconds.

This also deals high ticking damage to the party that is reduced by increasing your distance from the Magnéto-bras.

Casseur Oméga

He has no special mechanics.

Operation: Mechagon Hard ModeStep 1: Hard Mode First 3 BossesUnité d'oppression aérienne CT-8

You do not need to defeat the Trash while the Unité d'oppression aérienne CT-8 is above.

You can clear the Trash (or summon Salcrass) before the HK-8 moves to make it a little easier.

Unité d'oppression aérienne CT-8

It periodically summons 3 Fulgurotron X1 robots into each encounter that function the exact same as the ones from the HK-8 encounter.

You'll have to deal with the regular mechanics of the first three bosses, while having to deal with Fulgurotron X1s.

We recommend using a Druid with Sarments and Enchevêtrement de masse.

Step 2: Hard Mode Unité d'oppression aérienne CT-8Unité d'oppression aérienne CT-8Exploseur de tank MOD2

This mob has similar mechanics to the MK1, but hits harder.

It also has replaced its Décharge fulminante with Explosion fulminante, a split damage mechanic that forces players to be stacked throughout this phase.

Help soak Explosion fulminante.

Fulgurotron X1Fulgurotron X2

Individually, these are the exact same, but now, all three Walkie Shockies are connected by a Lien électrique.

This deals very high damage to any who remains in the Lien électrique and it ticks every 0.3 seconds.

Players can quickly walk through the Lien électrique to only take 1 tick of damage, but space is now even more limited.

Stay away from the Lien électriques!

The debuff will slowly stack on the party, reducing movement speed by 5% per stack.

This will cap at 16 stacks, slowing players by about 80%.

You'll have to defeat K.U.-J.0. while under this slow, so much sure to head to the Junk Cubes early when he casts Expulsion de flammes.

Hard Mode King Mechagon

Click the Red Button before the fight begins!

Annihilo-tron 5000

The Annihilo-tron 5000 has an energy bar that can be seen on the Boss Frames.

The Energy Bar drains at a rate of 20 energy every 9 seconds (2.22 energy per second).

When the Energy Bar hits 0 energy, the party will die after a few seconds.

Annihilo-tron 5000

Then, one at a time, each Panneau de saisie will flash a colour and picture until each Panneau de saisie has flashed once.

The colour and picture is not relevant and the only thing that your group will need to remember is the activation order of the Panneau de saisies.

The Panneau de saisies will all flash a Red Skull once again before all Panneau de saisies will reactivate with colours. This starts the "Input Phase", allowing players to click on the Panneau de saisies.

Players must then input the correct Termination Sequence, by clicking the Panneau de saisie in the same order that you saw earlier.

Annihilo-tron 5000

Players will be able to click on the Panneau de saisies starting at 11 Energy on the Annihilo-tron 5000.

This means that there's only 5 seconds to input the entire Termination Sequence.

This is not enough time for players to move between Panneau de saisies, so you'll need one person stationed at each of the Panneau de saisies.

Input Phase: When the Panneau de saisies reactivate, each player should click on their Panneau de saisie when its their turn!

every 45 seconds throughout the ENTIRE

Players should not stand near the Panneau de saisies until the "Input Phase" as Recalibrage might place a Orbe de plasma in the way or at a bad time.

Players should not kill the Unité aérienne R-21/X as the Termination Sequence is starting, as players may be stunned during the "Input Phase."

Mégadécharge, Magnéto-bras and Rayon coupant can line up with the Termination Sequence and you'll have to do your best to survive while paying attention to the combo.

Panneau de saisie

Assign each player one Panneau de saisie to pay attention to.
In Phase 1, we used 3 DPS and 1 Tank because the healer is very busy during this phase.

In Phase 2, we used 3 DPS and 1 Healer because the tank needs to stay in range of the boss.

Panneau de saisiePanneau de saisie

The player who is watching the first Panneau de saisie to activate should call "1!"

The player who is watching the second Panneau de saisie to activate should call "2!", after already having heard someone else call "1!"

e.g. If a player sees their Panneau de saisie activate and has heard other players already called "1!", "2!" and "3!", they would know that their Panneau de saisie is 4th and should call "4!".

I'm going to assume there's not really any Princesse Huhuran in this dungeon, and you probably missed an integer in the id :) Looking forward to it though!

edit: After reading the whole thing, this could have really profited from someone proofreading. A lot of random words missing makes this very hard to read (especially noticeable later in the article).

One thing I didn't see on here was an ability we found on K.U.J.O. A stacking debuff, noxious stench I think it is. To remove it, you need to pick up the dog's poop. So put one person in your group on pooper scooper duty.

Commentaire de SeyonMas

Why does the guide not mention the Welding Bots, Grease Bots, or Electro Bots that roam around and give very strong buffs?

Commentaire de Hykon

The guide doesn't cover the ability to remove the stacks during hard mode KUJO. If you click the poop on the floor that spawns during the fight, it does aoe dmg to the group but clears the slowing stacks.

I healed SoO on normal / heroic (mythic today) and that was walk in the park compare to this. This is suck with capital C. Not fun at all.

"His deadly ability is Venting Flames.

After a long cast time, K.U.-J.0. will deal very high fire damage to anyone within Line of Sight.
Players can use Junk Cubes or any corner of the Arena to hide from this ability."

Not true, if you hide behind anything except the boxes, you will burn. Also, if the dog faces a corner of the box, pile up on top of each other exactly on the opposite corner.

I have a question dont know if any of you experience this. Before the kujo fight got hotfixed and broken. I did a whole run with another group. And in the robo drome fight we did something... we dont really know what. But after the tank boss fell and while we were kiling the robot boss. An extra add jumped into de arena, de had some life, did some damage but most important would not shut up and kept on yelling. And we had to kill him, even after we had droped the tank boss and the robot boss.

When we did the fight again, the hotfix had already gone through, we did the fight again and the add didnt drop. And we got stucked in kujo since blizz broke the fight. We figured we activated hard mode or something. But reading this guide in detail i dont see any mention of this add, or even that the robo drome having a hard difficulty.

BTW the robo drome fight i mean the 5th fight.

So has any of you had this experience o know how to activate this add?

Edit - Just asked the tank since i was the healer, and he told me this add was a mecha-gnome.

The Input timing for King Mechagon's Hardmode is not always the same. While he usually activates it at 11 energy (5 seconds) It sometimes is delayed to 9 or even 7 energy remaining. See clip below for proof.

@warcraftdevs This is likely a bug and it interferes with reasonable player ability to complete the no-death Toute résistance est inutile achievement. Please take a look.

Cannot post links so here is what I can post:

I love this dungeon! Run it every week!

Commentaire de Thestis

K.U.-J.0. will cast Blazing Chomp on the Tank.
Had a resto druid that had a hard time dispelling this debuff. So druid tank went feral with guardian affinity and stayed in bear form for threat. Blazing Chomp was never cast - a way around this ability.

We discovered this when tank kept dying and dps were tanking and never got debuff.

So .... how do you go inside heroic junkwatt depot?

Commentaire de rapbandit

Can anyone confirm that Junkyard M+ end of dungeon chest drops the wrist for mages or you hv to run the workshop? Ty in advance!

Commentaire de Kurtosis

Tried solo'ing this on Heroic in TWW on 80 main. Got to HK-8 and the Overcharge Stations do not have 100 life as explained in the guide, but 604,800 life. And every time you stop and restart channeling, it restarts at 604,800. Seems impossible, but that's just an illusion.

Stand right next to the Overcharge tower, inside its ring that electrifies peridically, and channel on the tower till HK-8 goes Haywire. You won't get shocked or stunned standing there until HK-8 goes Haywire, and you only need to reduce the tower's life by about ~50 or so to trigger Haywire. Then run down and kill HK-8 while he's vulnerable.
