This fractal is divided into five rooms and linear hallways, having you slowly ascend the tower.
Rooms 1-2: Multiform Ambulatory Mobile Artillery
The first room has standard Toxic Alliance foes, simply kill them and move on. Between the two rooms is a slope you cannot return up. The second room is full of Twisted Watchwork enemies. Once they are killed, the first boss will spawn.
The Multiform Ambulatory Mobile Artillery is a mostly stationary boss who shoots projectiles, deals a spinning flamethrower attack and summons smaller Twisted Watchwork. It will periodically begin charging a room-wide explosion; get underneath Arkk's shield when this occurs. Upon reaching 33% health the boss will go into a mobile, bi-pedal mode (commented on by Arkk) which jumps at players and delivers powerful AoE slams.
Room 3: Altars
After a short hallway where you'll face Hallucinations, you'll enter the third room. There are three altars here that need to be captured by standing in a circular area around it, much like capture points in PvP. In the center of each altar is an orb that shoots out red damaging spheres in alternating patterns. Strafing around the edges of the circle will give you more time to dodge, and there will be occasional blue spheres that you can collect to heal you. The altars also spawn one Veteran Hallucination each, which despawns when the altar is captured.
Rooms 4-5: Siax the Unclean
The second hallway houses a small lake with Poisoned water and the elite shark Fleshgorge, and a ramp upwards. The ramp has explosions moving downward which can be dodged through. There is also a large plant which shoots poisonous seeds at the party, so keep moving.
Room Five has Siax the Unclean, the second boss, who will appear after a mob of Marjory and Kasmeer hallucinations appear and laugh. He will frequently charge up energy to devastate the room, which must be interrupted by breaking his Defiance bar. Siax will also infect party members with toxin. Shortly afterwards, they will vomit in a highlighted conic area in front of themselves; allies hit take damage and are re-infected, causing them to vomit again.
Room 6: Ensolyss
After Siax's fight, there will be a launch pad and a Mistlock Singularity. Taking the launch pad will take you to Ensolyss, the final boss fight of the fractal. Initially, the hatched Ensolyss only has basic melee attacks, but when brought to 75% health his body will grow, his health is reset to 100%, and the true fight begins. This phase is skipped on subsequent attempts.
Ensolyss is a demanding fight that has a great variety of attacks. Players must learn the timings of each attack and how to avoid damage, especially at higher fractal levels where the sheer amount of hazards makes revival very difficult.
Upon reaching 66% and 33% health, Ensolyss will become invulnerable and leave the arena temporarily. A large orb will spawn in the middle and emit constant streams of red damaging and blue healing spheres. Similar to the altars earlier in the fractal, there will be 5 smaller orbs that must be 'captured' by the party. During this phase the party receives Determination, an effect which will fully revive the party if the orb phase is successfully completed. At higher fractal levels, the center orb will periodically release a knockback shockwave that can be jumped over, and also barrage the ground with bouncing orbs. The outer edges of the room will also become ringed with poison, making the safe fighting space smaller.
At 15% health, Ensolyss will teleport to the middle of the arena, poisoning the entire area after a short while. Arkk will create a shield next to the boss, which will be the sole safe zone. The boss will remain stationary and take increased damage, but two forms of Nightmare Hallucinations will spawn. The first are normal mobs that attack the party (they can be used to rally off of should you or a party member down), the second are charging hallucinations that spawn on the edges and dash across the shielded area, their path indicated by arrows. Finish Ensolyss off to complete the fractal.
|Retrieval Squad||Nightmare Fractal||3|
|Find all the corpses of the adventuring party that preceded you.||1 Corpse Found||0|
|2 Corpses Found||0|
|3 Corpses Found||0|
|4 Corpses Found||0|
|5 Corpses Found||3|
- You'll find the first corpse near the beginning of the fractal, before the slope to the first boss's room.
- The second corpse can be found behind wood between the first boss's room and the three-altar room.
- The third corpse can be found in the three-altar room, under the path towards the right altar—there is a cloth wall you can walk through.
- The fourth corpse can be found on a ledge over Fleshgorge's lake.
- The fifth and final corpse can be found in a small outcropping just past the room in which Siax is fought.
|Maze Middle Manager||Nightmare Fractal||5|
|Capture the middle point in the Nightmare maze before capturing the side points.||Captured the Middle-Point First||5|
- In the second set of altars needing to be captured after the first boss fight, capturing the middle one first will net this appearance. This is the hardest altar to capture first, as it has three Veteran Hallucinations respawning from it, and the krait obelisk shards on either side will bombard the area with bounding orbs.
- The best tactic is to pull the three hallucinations off of the altar, and have one person begin capturing it while the other four kill the hallucinations. Once the hallucinations are killed, the rest join in capturing the altar.
|Shark Tank||Nightmare Fractal||3|
|Find and kill Fleshgorge the Shark in the Nightmare lake.||Killed Fleshgorge the Shark||3|
- You'll find Fleshgorge in the small lake just after the second set of altars needing to be captured. It will be around the bend and to the right. The water causes permanent poison that cannot be removed while within the water, and Fleshgorge hits hard even at level 25. Best tactic to deal with him is to have the tankiest player bring him towards the others who attack Fleshgorge at range on land.
|Volatile Evader||Nightmare Fractal||5|
|Kill Siax the Unclean without being hit by a hallucination's explosion.
||Killed Siax while Avoiding Volatile Hallucination Explosions||5|
- Starting at 75% health, Siax the Unclean will begin summoning one Volatile Hallucination per player, who chase down the player they are Fixated on and explode on them. To get this achievement, you must not let any Volatile Hallucination explode on you.
- One viable tactic is for all players to kite and attack other players' nightmares (as they will always be behind you, thus facing them slows you down enough for them to catch you). Another, trickier, tactic is to range the one targeting yourself with snares. It is also possible to dodge the explosion.
- Achievement qualification may be tracked via the Volatile Evader Eligibility effect, which will appear once the fight begins.
|Another Goo Puddle||Nightmare Fractal||1|
|Get crushed to a paste by Ensolyss.||Crushed to a Paste by Ensolyss||1|
- Standing directly under the pod Ensolyss spawns from will net you this achievement. Doing so will deal unblockable damage equal to 75% of your total health.
|30-Second Seizure||Nightmare Fractal||3|
|Capture all 5 points during the Ensolyss fight within 30 seconds.
||Captured All Points within 30 Seconds||3|
- At 66% and 33% health, Ensolyss will summon five altars that need to be captured. To get this achievement, all five altars must be captured within 30 seconds of their spawning. You will get the achievement immediately after the first time you do this.
Challenge Mote walkthrough
At Level 99, so long as at least one player has completed the Nightmare Fractal meta achievement, the party can partake in the challenge mote by speaking with the Harbinger of Woe. The challenge mote changes the three boss fights as well as the altar capture encounters. In addition, additional rewards are given after beating each boss.
You will first encounter the Red Static Assault Knight, and once killed both the Blue Dynamic Assault Knight and Green Synergetic Assault Knight will spawn. All three assault knights function the same way, with two primary attacks - a PBAoE knockdown, and a AoE pull that covers the whole room except where the Assault Knight stands.
After all three Assault Knights are killed, MAMA will spawn.
Initially, MAMA will be much like her standard level 99 variant but with faster and harder-hitting attacks. She will remain in the center and utilize ranged AoEs and a few PBAoEs when players get into melee range. She will also summon a large number of Twisted Horrors. The main changes come at 75%, 50%, and 25% health intervals at each of which she will spawn one of the three assault knights again.
In addition, at 33% health her skills change and she becomes mobile, with her skills focusing on knocking down and pushing players. In addition to crowd controlling players, her most dangerous attack will be leaving large red pools of poison on the ground, which last for a lengthy duration.
The hardest part of the fight will be when MAMA reaches 25% health, as both MAMA and the Assault Knight will focus on crowd controlling players, and can easily result in leaving little to no safe zones for players to stand.
- The location where these summons will be is always the same and centered around the location where MAMA spawns:
- The knight at 75% will be located east.
- The knight at 50% will be located north west.
- The last knight at 25% will be located south.
- The three shockwaves attack of MAMA can be dodged or jumped over.
- The single shockwave of MAMA when she punches several hits around her into the ground is recommended to be jumped over followed by an immediate dodge out of her pizza slice attack (or walk out of the slice if close to the edge of that aoe).
Similar to normal mode, there will be a room of two altars followed by a room of three, each altar guarded by 1 to 3 hallucinations. In addition to normal, however, are Elite Nightmare krait that guard the altars. Unlike hallucinations, these krait do not respawn, so the best tactic is to pull the krait away and kill them first. The orbs from the altars are faster and harder hitting; while not by a significant amount, it is not ideal to try to solo capture the altars.
After the second set of altars, a large number of Veteran Toxic Skales and Elite Toxic Skales will ambush the party from the lake. They can be easily dispatched if prepared for, however. You can also run past the skale pack, as they will not chase to the top of the slope.
Siax the Corrupted
Before Siax spawns, the Marjory and Kasmeer hallucinations will go hostile and attack the party. Duck back out of the room near the Mistlock Singularity, and re-enter after Siax appears. These illusions will not come back on future attempts.
Siax the Corrupted will require a good amount of heavy and coordinated crowd control. He will always begin the fight with his devastating delayed explosion attack, Caustic Explosion, during which he will also release bouncing orbs in every direction. Break the defiance bar to cancel the attack. The majority of the fight from this point out is straightforward; Vomit Toxin and Volatile Hallucinations (which begin spawning at 75%) will still be the primary threats to watch out for. Watch out for any red, expanding AoEs; once the inner circle reaches the outer, Nightmare Hallucinations spawn for each party member still inside, which take and deal a lot of damage.
Upon reaching 66% and 33% health, Siax will become invulnerable and teleport to the middle to the arena, channeling a delayed Caustic Explosion. Echoes of the Unclean (krait hallucinations) will spawn at the north, south, east, and western edges (four in total). If the Echoes are not killed before Siax's channel finishes, he will blast the area with his instant-killing attack, and the remaining Echoes will follow with their own Caustic Explosion (preventing survival via Mistlock Singularities).
One party member each should be assigned to a section of the arena, ready to DPS down the Echo as the phase begins; the lowest two DPSers should be together to compensate, and the highest DPSers ready to assist others.
- Be careful of the barrage of bouncing orbs that Siax emits, as well as any leftover Hallucinations.
- It is recommended to have one kiter for the green poison in the team, who is taking care of the green orbs (Siax is always targeting the furthest player away for that green orb attack). So there won't be any green aoes in the middle and instead at the corners of the area. At 66% kite the orbs are allowed to be at the NW, NE, SW, SE corners (x shaped on map). Whereas due to the rotation of where the shadows spawn at 33% they can be located N S E W (+ shaped on map).
- Save cc attacks for Caustic Explosion phases and dps attacks for Echo phases.
- It is also recommended to set a marker on the map for the players to go to in the Echo phase at 66% and 33% (alt+left click) and rotate clockwise at 33% to the next Shadow.
Ensolyss of the Endless Torment
Ensolyss keeps his big variety of attacks, but all of them are faster and grant you less time to dodge. The arena will also have its edges poisoned right from the start, and more space will be poisoned at 66% health (no further poison occurs at 33%). His tail swipes also have a stronger knockback, which can easily knock players into the poisoned edges.
Directly after each orb-capture phase (66% and 33% health), Ensolyss will channel in the center of the arena, releasing bouncing orbs and conic knockbacks everywhere. Quickly deplete his defiance bar to stop this. Below 33% health he also gains a new attack, which deals heavy damage to players nearby while releasing orb that apply a long knockdown. Avoid the arrows that indicate the orbs' path, and jump over the shockwave; it travels inwards towards Ensolyss, in contrast to the other shockwaves in this fractal.
- The pull "Search and Rescue" on a druid can be quite handy to get downed allies out of poison aoes or under the protection sphere.
- Spirit of Nature on a druid is good for 66% and the 33% orb-capture phase.

- Entering the fractal
- Dessa: Are those...tree people? They look angry. Be careful!
- Mysterious Asura: You again! What preposterous sum have the Inquest promised you for haranguing me? Wasn't the damage to the DDR enough?
- Mysterious Asura: Oh my. Judging by your slack jaw and torpid silence, it seems I misunderstood your involvement. Please, follow me.
- Mysterious Asura: Apologies for the golems and the gladiator. I presumed you were sent to collect a debt. I can see I was...hasty.
- Mysterious Asura: I'll get the door. My device was damaged in the prior chaos, so I've lost a bit of control, but I'm still quite capable.
- Arkk: My name is Arkk. We should form a mutually beneficial alliance. The odds are against our survival otherwise.
- Arkk: Let's discuss our team strategy. You hit these creatures harder than they hit you. I'll prepare my shield.
- Fighting the Multiform Ambulatory Mobile Artillery
- Arkk: Ah, a fascinating monstrosity! Intricate. Delicately balanced. Exquisitely dangerous. Kudos, Scarlet.
- Arkk: I'll protect you! Take cover under my shield!
- Arkk: Mmm-hmm, It has a bipedal attack configuration as well. How inventive.
- Arkk: A wondrous design, if flawed. Its remains may prove useful. Mother always said, "Enervate the implements you're given."
- Arkk: Nevertheless, well fought. Now regroup and prepare for more ferocious foes ahead.
- In the maze
- Arkk: Ah, a physical obstacle to confound and demoralize the spatially inept. Good luck!
- Arkk: Your progress is adequate. Keep moving, there are more altars ahead.
- Arkk: This maze is ample proof that violence is your strong suit. Speaking of which, let's move forward.
- Fighting Siax the Unclean
- Arkk: We're nearing the ultimate experiment, an entity utilizing a kernel of remarkable power.
- Arkk: With the DDR in disrepair after our first meeting, your assistance here will be crucial. I'll lend my aid where I can.
- Arkk: But first, another research experiment to overcome. It utilizes some extraordinarily deadly skills. Be ready!
- Arkk: Hallucinations, a remarkable tactic. Stay alert!
- Arkk: Strike quickly! Don't allow it to finish channeling its attack!
- Siax the Unclean:: (chant)
- Arkk: You have toxic sickness, how vile. Please refrain from regurgitating on others.
- Arkk: How did I not realize sooner that you are much too savagely competent to be hired by the Inquest for debt collection?
- Fighting Ensolyss
- Arkk: Here we are. This will be our most ambitious and lethal challenge today. But with great risks come great rewards.
- Arkk: Now listen closely, it could save your life. The creature in there is extremely volatile. We must work together.
- Arkk: At times you may feel that you are overmatched. You must pay close attention to my commands!
- Arkk: Given your destructive adroitness, there may even be a chance you won't be obliterated.
- Arkk: Go on. Given your penchant for murdering things, your mathematical chance of survival is greater than zero!
- Ensolyss: (mewl)
- Ensolyss: (shriek)
- Arkk: Quickly, retreat inside my shielding!
- Ensolyss: I am awake.
- Ensolyss: I am aware.
- Ensolyss: Suffer, mortal things.
- Arkk: The shield! Hurry!
- Arkk: I'll protect you! Take cover under my shield!
- Ensolyss: How dare you defile my birth chamber.
- Ensolyss: All your fears. All your delirium. Feeding me.
- Ensolyss: Suffer and die in terror.
- Ensolyss: My power, my awareness, grows by the moment.
- Ensolyss: I am hatred and horror made manifest.
- Ensolyss: The ouroboros turns eternally, vine and serpent entwined in me.
- Ensolyss: You may die now.
- Ensolyss: Stop! Your kind will not contain me.
- Ensolyss: I will not be destroyed by such as you.
- Ensolyss: No! I cannot be the last of my kind.
- Arkk: It's nearly dispatched — put it out of commission!
- Ensolyss: (roar)
- Leaving the fractal
- Arkk: Fantastic work. Truly. And now it's time that I terminate our verbal contract. Your recklessness has served my purpose.
- Arkk: I'll take the orb. You take solace in knowing your destructive exuberance has at least balanced the ledger between us.
- Arkk: I can reconstruct the diaphanous diffraction randomizer. And you no longer have to feel guilty for derailing my mission.
- Arkk: Now excuse me — I'm here for more than tourism and indiscriminate pillaging. You're of no further use. Stay out of my way!
- Dessa: You did it! Oh...you look...unhealthy. We should probably quarantine you when you return.
- This fractal island was added with A Crack in the Ice release.
- Unlike the original Tower of Nightmares foes, the Toxic Alliance sylvari do not have a downed state.
