Upon defeating Skorvald the Shattered and Viirastra they each drop a daily reward chest containing:

Challenge Mode[edit]

Rewards for each boss are daily per account.


Starting from the entrance, jump carefully down the rocks until you reach the large circular platform. Shortly after, the first boss of the fractal will spawn.

Skorvald the Shattered[edit]

Skorvald will perform AoE attacks that cover 25%, 50%, and 75% of the arena, in cone shapes originating from the center. Stay close to him to make it easier to move into a safe area. Below 50% he will occasionally spawn Solar Blooms; these explode after a while, so keep them near the edge of the arena by hitting them to knock them back. At higher scales below 66% he will occasionally teleport to one side of the platform and a big eye icon will appear above his head with a blue line connecting it to your character if you face towards him. Turn your back to him, or the eye will damage and fear you, putting you at risk of running off the edge.

At 66% and 33%, he will turn invulnerable, and you will have to take the ley-energy wind that will spawn at the eastern side of the platform. After being propelled to the nearby island, you will have to defeat a Veteran Flux Anomaly. It knocks back, so be careful not to stand too close to the edge. After killing it, take another ley-energy wind in an anti-clockwise direction to the other islands. Move quickly, as Skorvald will throw firey AoE onto the island once its Anomaly has been defeated. At higher scales he will also channel an orange circle that will slowly radiate out from the center of his platform. If it reaches the edge before all Anomalies are dead, he will wipe the party. That attack can be mitigated with invulnerability, but it's rarely necessary as there is plenty of time, even at tier 4. After defeating all the Anomalies, return to the boss platform.

Galaxy islands[edit]

Once you've defeated Skorvald, take the portal that spawns. After a short cutscene, you will be teleported onto a large platform situated inside a galaxy. You will be affected with Cosmic Energy from now on, and have access to  Celestial Dash.png Nova Launch as a special action skill. There are three locked portals on this platform: north, east, and south. Yokko will unlock the south portal. Going through the north portal will lead you to a series of small islands, eventually leading to Simon, a cat part of the hungry cat scavenger hunt.

Go through; you will find yourself on a series of small island rocks. Jump to each one using the ley-energy winds or Nova Launch, and destroy the various golems you find there. After reaching the largest platform, a large blue globolla marble will spawn. The goal here is to "bounce" the marble on a player's head by standing under it as it lands. White circles will spawn ahead of each bounce to let you know where to stand. Once it is destroyed, take another ley-energy wind to the nearby island. Destroy the golems there.


After reaching the final platform with Nova Launch, you will come across Viirastra and her many clones. Bounce one of the silver globolla marbles to initiate a short dialogue and start the battle.

She will start the fight with her three jump agony shockwave, and then move into a corner and begin casting a large amount of AoE marks. She will also summon Elite clones; deal with them and their descendant clones first.

Mechanics for phase 1 onwards
  • Dome and Corporeal Reassignment - A red skull symbol causes players to explode if ignored; the chosen player should move inside the dome in the center of the arena to prevent damage to your allies.
  • Agony shockwave - Viirastra jumps around three times and then slams the ground, causing a shockwave which applies Agony and knockback. It can be jumped over, blocked or dodged.
  • AoE marks - She covers the floor in expanding AoE circles throughout the fight.
  • Clones - Smaller versions of herself; these Elite clones, when killed, will split into 3 Veteran clones, and those into Regular clones. These clones will attack and channel lightning between each other and players.

After a period of time she will move to another corner and repeat her attacks.

On reaching 66% health she will split into 4 clones (1 per corner). They take insignificant damage from attacks. Breaking the defiance bar on each clone will destroy them, continuing the fight. During this split phase and the one following, players will be under the Determination effect. If all clones are destroyed, any downed or dead players will be revived.

Mechanics for phase 2 onwards
  • Globolla marbles - Bouncing these silver marbles refreshes Nova Launch, and prevents the appearance of red marbles.
  • Red marbles - Inflicts conditions when they come into contact with a player. Only appear when a globolla marble is dropped. [verification requested]

Upon returning, she will quickly channel a large AoE covering most of the platform and a shockwave. Her defiance bar will now lock. She then moves back to a corner and throws a globolla marble, which again is marked on the ground with silver circles moving in a circular fashion around her corner. Bounce it as before until it reaches Viirastra, where it will unlock her defiance bar once more. Dropping the marble causes damage to the party and spawns red marbles which complicate the fight and inflict many conditions. If it is dropped, she will also immediately summon a new one. Assign one or two players to bounce the marble.

At 33% health, she will split into 5 clones. 1 per corner, and 1 in the center. The central clone will throw orange orbs at various corners and add additional AoE circles, but can otherwise be ignored. Continue as you did at 66% health. Clone spawns increase in frequency as the fight continues.

Once she is defeated, your Nova Launch will be upgraded to Hypernova Launch and you can enter the spawned portal to return to the three-portal platform. Yokko will unlock the big, western portal; enter it to reach the final boss.


Use your  Celestial Dash.png Hypernova Launch to reach the boss platform which has an electrified perimeter and a reactor in each corner. To start the fight, you have to destroy the four reactors using the explosions of the Solar Blooms that spawn on each side of the platform near the edges. To get them into the corners, either push them using your basic attacks or don't attack at all and have the fixated person stand next to a reactor. Once all the reactors are destroyed, Arkk fires a giant laser through the middle of the platform that deals high damage and grants the achievement Blinded with Science. Arkk will then teleport to the platform and the actual fight begins. If you wipe during the fight, this part does not get repeated and the fight will start immediately.

Most of Arkk's attacks have long wind-ups and obvious telegraphs, you can just walk out of most orange AoE indicators. The Corporeal Reassignment mechanic carries over from the fight with Viirastra: The player with the red skull still has to stand in the black dome when it explodes. Don't hesitate to use  Celestial Dash.png Hypernova Launch to get there or to use it in place to avoid attacks that cover the entire dome; its cooldown will be reset if you explode inside the dome. Occasionally the big eye from the fight with Skorvald the Shattered appears above Arkk, turn your back to him or you'll get feared and damaged. This is especially important if you're targeted for Corporeal Reassignment since getting feared out of the bubble will result in a huge amount of damage to your whole party. If you get hit by the fear you can use  Celestial Dash.png Hypernova Launch as stun break. When a red marble appears above Arkk's head, shortly after it disappears again he'll shoot a ball at every player that bounces outward and leaves AoE fields behind which deal high amount of damage. These balls can be reflected or negated by projectile destruction. Alternatively you can just walk a few steps back when the marble appears and dodge/jump/use  Celestial Dash.png Hypernova Launch back inwards as soon as it disappears.

At 80%, 50% and 30% of his health, Arkk will become invulnerable, charge a big attack and summon a Solar Bloom on each side of the platform. They fixate on the player closest to their spawn location and need to be pushed into the reactors just like at the start of the fight. When Arkk's big attack is charged, all remaining solar blooms will explode. If any reactors are still active after that, Arkk will deal a huge amount of damage to the whole party. The attack can still be dodged or negated through invulnerability. Arkk will then restart his attack and summon a new set of solar blooms. Once all the reactors are destroyed, Arkk's Defiance bar will unlock and must be broken in time to avoid another big attack. Remember that  Celestial Dash.png Hypernova Launch includes a launch that can help with that.

At 70% Arkk will teleport away and summon an elite version of the Legendary Archdiviner and four Fanatics from the Cliffside Fractal. Try to kill the Fanatics first so you don't have to deal with them when Arkk returns to the platform after the Elite Archdiviner has been slain.

Below 70% Arkk gains a new attack: A ring that expands outward and floats anyone that gets caught in it. It can be jumped over to avoid it.

At 40% Ark will disappear again and summon an elite version of the Legendary Brazen Gladiator as well as the four kitty golems from the Chaos Isles Fractal. Deal with the golems first and jump over for the shockwave the Elite Brazen Gladiator occasionally sends out. Make sure to interrupt his big pull attack below 50% health by breaking his Defiance bar. Remember your Hypernova Launch, it can be used as CC or to get to safety if the CC fails.

Below 40% some of the platforms start to disappear. If you fall down, you'll get teleported high above the platform and have one more chance to get back on the platform with your  Celestial Dash.png Hypernova Launch. If you miss the platform while falling down, you'll be killed instantly. Additionally Arkk will now start to roll red marbles over the platform. A small arrow will indicate their path, so they're rather easy to avoid.

Now you'll just need to keep calm, do the last reactor phase at 30% and remember that Celestial Dash.png can get you out of any sticky situation. It can even be used while downed for a short window of invulnerability!

Once Arkk is defeated, the fractal is complete. If you want, you can leap over to the DDR platform with your  Celestial Dash.png Hypernova Launch or use the ley-wind to reach the portal back to explore the rest of the Fractal.

Challenge Mode Walkthrough[edit]

The Shattered Observatory meta achievement must be completed by the person activating the Challenge Mote. Players attempting this Challenge Mote should bring Crowd Control skills and be comfortable using their Special action key. While not required, it is recommended that groups bring one player capable of healing the party, at least one source of group Stability, and consistent boonstrip if Mistlock Instability No Pain, No Gain.png No Pain, No Gain is active. Standard boons like Quickness, Alacrity, Might, and Fury should be covered party-wide.


Up until the final phase, Skorvald's attacks in Challenge Mode are similar to his attacks in normal mode, although they cover a larger area, do more damage, and occur more quickly.

100% - 66%

For the first 66% of the fight, Skorvald will alternate between several attacks. He will create a circle of triangle AoEs, in a line-pattern. Rotating clockwise after each one spawns and dissipates is a good way to avoid damage and knockbacks. While this attack is in effect, he will frequently cover 75% of the platform in another AoE circle. A floating Eye will occasionally appear above his head or to the side of the platform. Looking at the eye will damage you and cause fear. The eye will also fire a laser, which will be marked by a set of horizontal AoEs.

66% split phase

Skorvald will become invulnerable and begin channeling a massive attack. Players will be prompted to go to the southwest floating island and travel counterclockwise around the arena, killing Veteran Flux Anomalies. These Anomalies have two main attacks to worry about. They have a knockback/crowd control combo attack that can isolate and knock a player off the small island. The anomalies on the 2nd and 4th islands may also "jump" into the air, evading attacks and slamming back to the ground. This slam sends out a shockwave that knocks players back. This knockback may be jumped over, dodged, or prevented with Stability. Once an anomaly has been slain, Skorvald will throw a fire-bomb onto the platform, forcing you to move on without a break. Occasionally Skorvald will spawn AoE circles under each player, applying stacks of Burning when they go off. Once all Anomalies have been slain, players can return to a stunned and dazed Skorvald.

66% - 33%

After Skorvald recovers from having his defiance bar broken, he will fixate one player, teleport to the edge of the arena, and rapidly dash through them across the platform while evading. This dash attack does modest damage and knockback to any hit players, and is performed three times on the same player. Afterwards, all attacks continue as before, with the addition of Solar Bloom orbs. These orbs will fixate on a particular player, drawing a line to them. Eventually they explode, dealing large AoE damage and causing an enormous knockback. Use ranged attacks to push it to one side of the platform, away from allies, so it can explode safely on its own.

33% split phase

Identical to 66% split phase.

33% - 0%

Skorvald will become enraged shortly after players return to the main platform. He will gain an extremely damaging aura inside his hitbox and spin around at the center of the platform, unleashing massively damaging purple lines in the direction that he is facing and repeatedly knocking players back. He will have a locked defiance bar during this attack. Do not stand inside his hitbox during this attack as it will down players within seconds. After finishing his first spin attack, Skorvald will summon a set of clones that will dash through the center of the arena, one by one. Like the attack at 66%, they will fixate on one player with a purple marker above their head. Their attacks can be dodged or blocked. Skorvald will also begin dashing around the room as well, occasionally returning to the center for his spin attack. During the entire last phase, Solar Blooms will keep spawning; Eyes and lasers will continue to spawn.

  • Skorvald's pizza-slice attack can be hard to discern from the wider AoE, as the markers of these two attacks overlap. Turn your post-processing settings down to improve visibility.
  • Skorvald's explosion at 66% and 33% can be dodged, although this is not recommended.
  • Some groups will use portals (e.g., with White Mantle Portal Device) to speed up the split phases, in particular porting from the final island back to the main platform to gain maximum value from Exposed. This strategy should be coordinated in advance.
  • Stability is highly important for this boss, especially in the final phase, where the knockbacks and high damage pressure can become overwhelming. It is also helpful for the island phases, although remember that the shockwave attack can be jumped or dodged.


Artsariiv is quite similar to her normal-mode counterpart, though her bomb-shelter is less accessible and she covers the floor in AoE markers. It is vital that players understand how to use their Special action skill  Celestial Dash.png Nova Launch, as the Aegis, stun-break, and evade it provides are invaluable.

Throughout the fight

Main Attacks:

  • Staff Leap Combo - Artsariiv moves across the room in a 3-hit chain, unleashing a shockwave at the end. This shockwave may be blocked, evaded, or jumped over.
  • Corporeal Reassignment - Artsariiv places a bomb on a player, indicated by a skull icon Jade Maw agony attack.png. A Temporal Anomaly in the center of the arena will also appear, and can be killed to spawn a bomb shelter ("dome"). If the targeted player is not in the dome when the bomb detonates (~10 seconds), the entire party will down.
    • The bomb shelter will last until Artsariiv moves to another corner.
  • Eye Laser - Artsariiv unleashes a massive laser attack in 3 directions. Players looking towards the Eye marker will be feared and take additional damage.
  • Small circles - Artsariiv and her clones will cover the platform in AoE circles in various patterns.
  • Red marbles - Artsariiv will throw red marbles, which cause damage and knockdown upon hitting.
  • Red orbs - Artsariiv will target a player and throw clumps or lines of damaging red orbs.
  • Small slam - Artsariiv will spawn a circle AOE around her, and after a brief delay will deal heavy damage and knock back players around her.
Fight start

After beginning the fight with an eye laser attack, she will leap her way to a corner of her platform, indicated by a damaging purple field. A Temporal Anomaly will spawn and a player will be targeted with Redirect Anomaly.png Corporeal Reassignment. Kill the anomaly and follow Artsariiv. At the corner, Artsariiv will gain a CC bar. Break it to stagger her and phase to 66%, reflecting projectiles and sharing Stability as necessary. The player targeted for Corporeal Reassignment should wait at the bomb shelter, or SAK to it if they already went to the corner, then rejoin the group.

66% split phase

Upon reaching 66% health, she will disappear and summon 5 clones: 4 in the corners, and 1 in the center. Break the CC bar of each clone as you would in normal mode. Be wary of the additional AoE circles along the ground. Players will have the Gambit Exhausted.png Determination effect, resurrecting the entire party as long as the phase is completed.

66% - 33%

As soon as the phase ends, Artsariiv will become vulnerable and cast a large AoE circle covering most of the platform. Time your dodge to coincide with the indicator, move to a corner of the platform, or use your  Celestial Dash.png Nova Launch to evade it. A shockwave will follow the attack. After the shockwave, she will cast an interesting pattern of circle AoEs that down players caught inside. She will then teleport to a side of the arena and unleash an Eye Laser before traveling to a new corner with her Staff Leap Combo. At this time, another anomaly will spawn and a player will be targeted with Corporeal Reassignment. Kill the anomaly quickly and proceed to the targeted (purple) corner.

As in Normal Mode, Artsariiv will drop a Globolla Marble ("ball"). One player must "catch" the marble by standing under it when it bounces. The bounce pattern is fixed but less linear than in Normal Mode, so be ready with the Special Action Key and pay attention to the blue AoE indicators.

Unlike in the first phase, Artsariiv will not have a CC bar until after the marble is returned to her.

33% split phase

Artsariiv will disappear and summon 9 clones: 3 along each side, and 1 in the middle. Players will have the Gambit Exhausted.png Determination effect, resurrecting them as long as the phase is completed. Split and CC them as quickly as possible to phase. A clone may drop a Blue Marble, so be prepared to catch it.

33% - 0%

This phase is identical to the 66% - 33% phase, with the exception of the Globolla Marble taking a new, more convoluted path.

  • Large amounts of CC are critical to completing the encounter quickly and painlessly, particularly during the clone split phases.
  • Correct usage of Nova Launch, the special action skill, makes the encounter much easier. If Artsariiv's knockdowns are not mitigated with Stability, this skill can be used for an easy and low-cooldown stunbreak. The invulnerability and aegis can also be used to avoid dangerous attacks or alleviate pressure.
    • Catching a marble or detonating a bomb in the shelter will refresh the cooldown of Nova Launch.
  • One stack each of Aegis and Stability is enough to negate the down and knockback from the initial slam attack at 66% and 33%.
  • One player should be designated as the primary marble catcher. This player will vary from group to group, but will often be the non-healing boon support, or anyone who can do some or all of their job from range.
    • If the primary catcher gets a bomb, it is very difficult (though not impossible) for them to catch the first bounce and detonate the bomb safely. Someone in the group should backup the first bounce. The bomb will detonate between the first and second bounce, and the primary catcher can easily SAK to the second bounce in time.
  • Artsariiv will fire red orb projectiles every 2nd attack after reaching the corners (her first attack at 100%, and her second attack after releasing the marble in subsequent phases). These orbs can be reflected, dealing enormous damage to the boss. A high-damage power DPS class will do the most damage, (e.g. Power Soulbeast with Whirling Defense, Power Virtuoso with Feedback), although any class benefits from reflecting.


After clearing Artsariiv, your special action key is upgraded to  Celestial Dash.png Hypernova Launch, which is now a CC skill (launch) and blast finisher, in addition to its previous effects (invulnerability, stun break, aegis, and mobility.) Using this skill often is critically important to succeeding in the fight. Arkk utilizes the same skills as in his normal mode, with increased damage, area covered, speed, or extra mechanics. Some mechanics from Skorvald and Artsariiv are repeated. Bringing Crowd Control skills (CC) is required.

Re-used mechanics/skills
  • Corporeal Reassignment: As in Artsariiv's fight, a player will be marked for Corporeal Reassignment with a red skull. A blue anomaly must be killed to spawn a shelter and safely detonate the bomb. Unlike in the Artsariiv fight, the anomaly spawns randomly somewhere in the arena, and the dome will disappear after the bomb detonates.
  • Blinding Radiance: First move when you engage Arkk in combat, an Eye will appear above his head. After a short delay, any player facing the else Eye will receive heavy damage, Fear, and Blinded. This is the first mechanic used and recurs throughout the fight.
  • Blinding Radiance Laser: Similar to Artsariiv's triple laser attack. Large rectangular AoEs will spawn to signal that a laser attack is imminent. This attack will down players caught in it. A Blinding Radiance eye will also spawn at the source of the laser and go off when it activates.
  • Triangle AoEs: Arkk will summon rings of triangle AoEs counterclockwise, similar to Skorvald's. Hit players will be damaged and knocked back. As with Skorvald, this attack may be avoided by "chasing" the triangles counterclockwise, or by stepping between the triangles as they go off.
  • Solar Fury: Arkk will start to channel, with a red marble appearing above his head. When it disappears, he will red marbles at all players, where they will bounce, leaving behind pink/purple AoEs that deal enormous damage.
  • Triangle Cannon Slam: Similar to Skorvald's. Arkk will single out one player and bring his cannon back behind his head. He will track the player as they move until the last second before he slams the hammer/cannon down. Shift your character back and forth to check for when he stops tracking you. Stay close to him to give yourself more room to dodge.
    • This attack knocks players back and can easily knock someone with bomb out of the shelter, causing a wipe. Maintain awareness, move predictably, and direct the triangle away from your allies. If you are targeted by this attack **and** you have the bomb, be prepared to dodge.
  • Gravity Well Shockwave: A small orange circle will flash below Arkk. This is a warning that he is about to spawn a set of concentric ring AoEs that will pulse, first outwards then inwards. You can dodge or jump over these AoEs. If you are hit, your character will take significant damage and Float for a short duration.
New mechanics
  • Green Circle/Temporal Realignment: A green circle appears on one player. If two players are not in the circle when it times out, everyone will take massive damage. Otherwise, a moderate amount of damage is distributed among the players in the circle, similar to Captain Crowe's green circle attack from Siren's Reef Fractal.
  • Diaphanous Shielding: Arkk deals 25% more damage and takes 10% less for every active reactor.
100% - 80%

The fight will start quite chaotically, so it's important to be prepared for every mechanic. A blue Temporal Anomaly will spawn somewhere near the side of the platform. One player will be selected for Corporeal Reassignment (bomb), and a second player will be selected for Temporal Realignment (green circle). Both of these mechanics will down players if handled incorrectly. One player will also be selected for the triangle cannon slam, which should be dodged or negated with stability and directed away from the player with bomb. Once all this clears, the fight proceeds in more of a rhythm. Arkk will fire off red marbles and alternate between attacks.

80% split (Solar Bloom phase #1)

At 80%, Arkk will become invulnerable and begin channeling a massive attack. If the 4 reactors are not disabled in time, it is usually a party wipe. Solar Bloom orbs will spawn and fixate on the player standing closest to them. Lure or knock them into reactors to destroy them and end the phase. If the orb is close enough to a pillar that it explodes on it upon the phase ending, it will still disable the reactor.

80% - 70%

Arkk will spawn a CC bar, downing the party if it is not broken. CC the boss and burn him down to 70%. An anomaly/bomb will usually spawn during this phase (or earlier in groups with low DPS) and may need to be dealt with. The bomb will not detonate if the boss is phased.

70% split (Archdiviner)

Arkk will leave the platform, leaving behind a (considerably lower-health) Archdiviner and 4 Fanatics. Arkk will periodically launch a trio of Blinding Radiance Lasers similar to Artsariiv's.

70% - 50%

The fight continues as before, with a Blue Anomaly spawning and AoE attacks and marbles from Arkk. He will also begin using more shockwave attacks, including one that acts as a Gravity Well.

50% split (Solar Bloom phase #2)

Identical to Solar Bloom phase #1.

50% - 40%

Identical to the previous phase at 80%-70%.

40% split (Gladiator)

Arkk leaves the platform and summons an elite version of the Chaos Fractal final boss, the Elite Brazen Gladiator. He also summons 4 miniaturized versions of Blight, Chop, Plink, and Doc. Be careful when lowering the Elite's health below 50%, as his spinning attack also exists in the elite version. Lasers cannons will continue to fire, now through the center of the platform. Your special action skill also has a knockdown, so it can be used to supplement CC.

40% - 30%

The floor will begin dropping out, marked by red arrows. Use your special action key to avoid or jump over gaps. Getting stunned, feared, lifted, or knocked back may cause you to fall through the floor. If this happens, use your SAK to return to the platform once in range. Falling past the platform a second time will kill you instantly. All other mechanics will still be running, so be extra careful during this phase, particularly with the bomb mechanic. If you're marked with the bomb as you fall, it's likely you'll explode and kill teammates, as it takes quite a while to fall. The bomb shelter may be partially missing floor tiles, so be careful.

30% split (Solar Bloom phase #3)

Identical to previous Solar Bloom phases, with the possible exception of floor tiles being absent. These will respawn shortly.

30% - 0%

Break Arkk's CC bar and continue as before. At 15% and occasionally thereafter, Arkk will spawn a Blinding Radiance laser through the center of the platform. Move and/or dodge before it goes off. The Solar Fury attack will be used a maximum of 3 times during this phase.[verification requested]

  • Arkk's Solar Fury attack (bouncing red marbles that leave behind purple-red AoEs) is easily among his most dangerous, particularly if multiple AoEs spawn on top of one another. Each player can negate one of the Solar Fury marbles, and the subsequent AOEs, using a well-timed Hypernova Launch. Players should be in the air when the marble collides with them (although the exact timing may vary with ping). This attack may also be distorted.[verification requested] Reflects should be used only with caution, as they may cause AOEs to spawn in unpredictable locations.
  • One player should be assigned to kill anomalies when they spawn. This is usually the non-healing boon support, or any player with ranged cleave.
    • The anomaly may not need to be killed if it spawns shortly (<10 seconds) before Arkk phases at 70%, 40%, and 0%. If in doubt about the timing, clear the anomaly anyway.
    • If the person who should be killing the anomaly is slacking, don't hesitate to do it yourself. Everyone loses if the bomb goes off.
  • A common mistake among newer players is to stare at the Blinding Radiance eye. Ensure your character (not your camera) is facing away from the eye when this attack goes off.
  • The group should split to tether orbs and move them in the same direction. Most pug groups go clockwise by default.
    • The easiest and fastest way to knock a Solar Bloom orb into a reactor is to use ranged attacks. Standing outside the damaging field and to the left of the orb, two or three ranged attacks will knock the orb into the correct reactor.
    • Melee attacks may also be used, but require one to stand in the damaging lasers.
    • Do not blindly autoattack your orb, or someone else's orb, in the wrong direction.
    • If not attacked, the orb will gradually approach the tethered player. This is an easy way to fix a messy orb phase - just SAK over to the desired reactor and wait for the orb to come to you.
  • The most dangerous phase for newer players will likely be the 40% phase, as Arkk will use almost every attack in addition to removing the floor. Focus on staying on the platform while dealing with the bomb, green circle, and marble mechanics, as before. Don't greed DPS until you're confident.
  • The Powerful Potion of Slaying Scarlet's Armies works against Arkk and is the best-in-slot utility for any power build.
    • Condition damage does not benefit from slaying potions, so condition-based builds should stick with their normal utility.

Entering the fractal
Dessa: Oh, thank the Alchemy you're alive.
Dessa: Something changed in the teleportation algorithm—you were lost in a sort of...void.
Dessa: My assistant Yokko pinpointed the error, but it still took us days before we were able to bring you back.
Yokko: Glad to have you back!
Dessa: Not again... Yokko, take the controls.
Yokko: Already on it!
Dessa: Where are these creatures coming from? How did they find the observatory?
Dessa: Listen, whatever is trying to break through that rift is too powerful for us to handle alone. We're scientists, not soldiers. I have to ask for your help one more time, friend.
Fighting Skorvald the Shattered
Skorvald the Shattered: Finally, a foe who deserves killing. Make peace with your death, "heroes".
During the fight with Skorvald the Shattered
Skorvald the Shattered: My hatred can't be bound any longer.
Dessa: Don't look at it! Shield your eyes!
Skorvald the Shattered: The anger...the must be unleashed!
After defeating Skorvald the Shattered
Skorvald the Shattered: So close to freedom...
Dessa: Yokko, status report!
Yokko: The rift appears to be stabilizing, but I can't close it. Something on the other side is keeping it open.
Dessa: Insoluble!
Yokko: See? I knew it!
Yokko: This is what happens when you work in an extremely volatile environment that could collapse on itself... at any time!
Dessa: We won't have long until the rift becomes unstable again. You'll need to go through and stop whatever's keeping it open.
Yokko: Um... You first.
After crossing the rift
Yokko: Whoa... What a trip. Where are we?
Yokko: Is that...? The architecture, the symbology—this is asuran technology!
Yokko: This place, it's imbued us with some kind of magical energy! I think I can-
Yokko: (screams)
Yokko: Ha-ha! Terrifying. Your turn!
Yokko: It looks like we need an additional power source to open the main gate. Hmmm, what's this?
Yokko: Hang on, this... this teleportation algorithm is like the one in the observatory! I think I can recalibrate it.
Yokko: Just a second... And... there! Portal's open! Head on through and investigate!
If you interact with the console and open the left gate before the previous conversation is finished, it'll be cut short and the rest is replaced with
Yokko: Oh. You opened it already... Well, i guess you already know what to do then.
After the portal
NTBD Mk. 5.1: Alert! Alert!
NTBD Mk. 5.1: Detection-noted.
NTBD Mk. 5.1: Assistance-requested!
GL-XC S7M: Assistance-acknowledged.
After the fight with the small golems
NTBD Mk. 5.1: Disengaging.
Approaching the elite golem
Elite GL-XC S7L: Alert! Threat-incoming.
Elite GL-XC S7L: Engage! Engage!
After the encounter
Elite GL-XC S7L: Task-failed.
Elite GL-XC S7L: Remain-here.
After the Globolla puzzle
Elite GL-XC S7L: Area-requires-protection.
Elite GL-XC S7L: Your-assistance-is-required.
Approaching the elite golem again
Elite GL-XC S7L: Detection-noted.

During the encounter
Elite GL-XC S7L: Unit-damaged. Repair-requested.
After defeating the golem
Elite GL-XC S7L: Task-failed.
Approaching Viirastra for the first time
Viirastra: More strange new friends! Wonderful!
Viirastra: Two arms...two legs..a that little one from earlier. He was much too serious. I was happy to see him go.
Viirastra: Stay. Let's play a game! Let's entertain one another!
After wiping and coming back to Viirastra
Viirastra: You've come back. Tremendous! Let's play another game!
During the fight with Viirastra
Viirastra: Watch this! You won't believe your eyes, truly!
Viirastra: Oh, I see this is much too easy for you. Let's make it more exciting. With marbles!
Viirastra: Such fun! It's fantastic, isn't it?
Viirastra: The game is almost over, but the best part is always the ending!
Viirastra: I know all kinds of tricks, see?
If you drop an orb during the fight
Viirastra: You dropped it. Let's give it another try!
On defeating Viirastra
Viirastra: (laughs) What fun! I need a rest.
Viirastra: Here, I'll give you this orb. That impatient little man with the sharp teeth gave it to me—I want you to have it!
Viirastra: Come back soon, and we'll play another game together!
After defeating Viirastra
Yokko: Watch out, creatures from the beyond, Yokko's here to... Oh, what? You guys already took care of it? (sigh)
Yokko: You found a power source, good! Let me just...
Yokko: There! I think I did that right.
Yokko: I opened the way back! Come on!
Yokko: Nice work. Now, let's see here...
Yokko: It looks like that's enough power to open the main portal.
Yokko: Yes! I did it! Er... We did it! Wha—whoa. We're not going into that, are we?
Yokko: fine! You only live once. Right?
After entering final portal
Yokko: This place is incredible! Wow! Just...just look at it!

Diaphanous Diffraction Randomizer: Sequence...interrupted.
Arkk: (growl) Troubleshoot!

Arkk: Sometimes I forget you're an AI. With a mute function. Now, quiet. Let me work.
Diaphanous Diffraction Randomizer: System—architect's—social—protocol—deficiency—logged.
Entering the fight
Yokko: All right, let's do this!
Yokko: We need to get his attention somehow...
Yokko: The raw energies contained in those solar blooms... I wonder if... Try knocking them into those reactors!
Arkk: You! How are you here? Unimaginable. Unacceptable!
Yokko: Whoa, buddy. It's okay. We're just here to, you know, stop you. You're literally tearing apart the fabric of the Mists!
Arkk: Enough! Your interference must cease! Go. Away.
Arkk: See? This is the price of your incessant desire to pry into things beyond your understanding. Satisfied?
During fight with Arkk
Some lines will be repeated throughout the fight
Arkk: Inconsequential! I'll deal with you myself
Arkk: Recognize this? I found it on that dreadful pirate you mercilessly slaughtered over and over and over again!
Arkk: Stabilizing mechanisms reversed. This weapon's full potential is about to become a reality!
Arkk: I've harnessed the chaos of interminable space-time!
Arkk: Reckless dunderheads! You want more? Take it!
Arkk: Obstinate goons! You leave me no alternative.
Arkk: Get. Out.
Diaphanous Diffraction Randomizer: DDR—Stability: 80—percent.
Diaphanous Diffraction Randomizer: DDR—Stability: 60—percent.
Arkk: Now you're in my domain. I set the parameters. I control the variables. Try to keep up.
Arkk: I've harnessed the chaos of interminable space-time!
After defeating Arkk
Arkk: You destroyed my defenses, but I've triggered the final sequence. There's no stopping it!
Diaphanous Diffraction Randomizer: Attention. Diffraction—imminent.
Dessa: Wha...? Who...?
Arkk: This isn't the place for explanations. Quickly... You look so young...
Dessa: This device... Are you the nuisance responsible for destabilizing the fractals? The variables it's created are a headache!
Arkk: Nuisance? The DDR is a work of a genius who also happens... No time, the geochrono transparency readings—time to escape!
Dessa: DDR?
Arkk: Diaphanous Diffraction Randomizer, obviously. Now...
Dessa: Out of the way. Let me see those readings.
Arkk: I guess you were always stubborn.
Dessa: Quiet! I'm trying to analyze these readings. They're extraordinary!
Arkk: Well, yes, I spent years...
Dessa: Who...? By the Alchemy, this is incredible work! These've ripped a hole...
Arkk: Back to our home.
Dessa: Home? Years? Arkk?
Arkk: Of course.
Arkk: (sigh) I should've anticipated this. Hello, Mother.
Dessa: Arkk, I... You've done amazing work here, Son. This should transport us back to the primary Tyrian reality!
Arkk: Unquestionably.
Dessa: what cost? This could destroy the Fractals of the Mists, and wipe everything inside the fractals from existence!
Arkk: What existence? Mother, this is not reality. We are the only legitimate life-forms here!
Dessa: Are you certain? What about all the Tyrians helping the observatory stabilize the fractals? What about my friends here?
Arkk: These... tourists are using your prison purely for entertainment purposes!
Dessa: They're performing important research that I've dedicated—
Diaphanous Diffraction Randomizer: Geochrono—transparenc—maximum—reached. Congratulations!
Dessa: should've worked by now. The readings are perfect. We can argue all we want, but it's not happening.
Arkk: It must. My calculations are undeniable!
Dessa: There's a variable you didn't account for.
Arkk: Impossible. I've accounted for every conceivable...
Dessa: Arkk.
Arkk: ...planar existence in that continuum...
Dessa: Arkk.
Arkk: ...near infinite...diffraction...unless...unless...
Dessa: You've figured it out, haven't you. Go ahead. State the only possible conclusion.
Arkk: ...Unless the targeted entities...are...inanimate...
Dessa: Yes. We're stuck in this time loop, too. We can't leave because we're not real.
Arkk: Neither of alive. Not really. We only exist in the Mists...echoes of ourselves.
Dessa: Otherwise your device would've worked. As you said, your calculations are correct...
Arkk: Yes. Yes. Small consolation... I failed you, Mother.
Dessa: It's not your fault, Arkk. All of this is because of me! We have to stop it! We can't destroy the fractals for nothing!
Arkk: You're right. We have to reset the loop. It's the only way. But that will mean—
Dessa: I know. It's a price I'm willing to pay. I'm proud of you, Son. Your theory proved true.
Arkk: I...I'm pleased I was able to see you again, Mother.
Dessa: And as long as we exist here, there's a chance we'll see each other again.
Dessa: But only if the fractals themselves survive. Let's end this. Together. Mother and son.
Arkk: Together. If we stay, the fractals endure... and so do we, after a fashion. I'm ready, Mother. Let's begin...again.
After Arkk and Dessa disappear
Diaphanous Diffraction Randomizer: System—architect—not—detected. Logging—out. System—shutdown—sequence—initiated. Good-bye!
