Scolopendra and the Nine-Tier Attack: Dungeon Crawler Carl Guide

Signet’s circus and the aftermath of an attack

The Mold Lions were once ordinary circus animals. Their bodies now contain vines and spores associated with Scolopendra. Signet says that even a microscopic surviving spore can return to the controlling vine and grow into another lion the following day.

Signet explains that the catastrophe killed some of the circus’s people and transformed others, including Grimaldi and Heather. Grimaldi became a vine that controls parasites inside other performers. Their altered bodies and relationships sustain the violence that repeats around the circus each night.[1]

Tish’s warning

In a letter to Ghazi, Tish argues that Scolopendra cannot be defeated without the artifact he is researching. Carl finds the letter among material connected to the Gate of the Feral Gods and the summoning that trapped the mage.

Tish urges Ghazi to stop pursuing his current course and use his work for a larger purpose. Her belief gives Carl another reason to investigate the Gate, although he has no way to test her claim about Scolopendra yet.[2]

The Hunting Grounds preserve conflicting histories

Clint and Holger give conflicting accounts of how the Chee were transformed. Their stories involve High Elves, stolen magic, poisoned crops and a wounded sea worm, but disagree about the order and causes of events. Carl also remembers a Cookbook version involving a dwarven tower-city.

Prudence says the Ursine mothers became dinosaurs during the attack. Tina, whose mother is Kiwi, was the only child at an interrupted dance recital to become a giant creature. Prudence sees the catastrophe as religious punishment, while also describing abuse by the clerics before it happened.

Tina’s description says the ancient attack transformed the Hunting Grounds’ inhabitants except for the High Elves. At the masquerade, Carl sees a ceiling image of Scolopendra sleeping around a tree.[3]

An early warning alarms the people running the show

Arief’s description attributes the Semeru’s mortality to the Nine-Tier catastrophe. Later, during the warlord council, Stalwart strikes Chaco and the system announces that Scolopendra stirs. The announcement does not explain exactly what has disturbed her.

Odette says no previous season has received such a warning. The final boss was supposed to wake only when crawlers reached the eighteenth floor, so her early stirring alarms the people watching the season.[4]

The broken Nothing reaches the lair

After Carl and Donut descend, Justice Light carries out the operation he stayed behind to finish. The Gate’s portal into the Nothing, a connection to Floor Twelve, a demon trap linked to Sheol and the freed beings’ worship connections bring separate realms together.

The system announces that the Nothing has broken and is draining into the Halls of Ascendency, Sheol and Scolopendra’s Lair. Scolopendra awakens. Guests are directed toward refuge on Floor Sixteen, but must first cross the Backstage Death Maze on Seventeen.[5]

The first attack transforms Carl

Quasar reports that Scolopendra is awake and moving as guests try to escape the lower floors. Shortly before the final race, the AI announces the Nine-Tier Attack. It describes Scolopendra as a mindless natural force.

The sequence contains nine attacks. The first four have temporary effects, and the early attacks are at least three hours apart before the timing becomes randomized. They reach Scolopendra’s levels and levels containing crawlers, with exemptions for particular people on Sixteen and Seventeen.

The first attack, Beast of Burden Sin: Transformation, has a twenty percent chance of affecting each unprotected target. Donut, Jamal and Samantha escape it, but Carl becomes a dachshund. Crawlers stay transformed until they cross a stairwell; NPCs and other targets keep the effect for six hours. With the race about to start, Carl can no longer operate the truck normally.[6]

The AI describes an original Nine-Tier Attack

During the parade, the AI describes an ancient Primal collective created in the hope of ending violence. It became a weapon intended to erase biological life. A resistance built Primal Engines as lifeboats, hoping they would restore life and habitable worlds after the collective failed.

According to the AI, the collective launched the original Nine-Tier Attack before those preparations were finished. Believing biological life had been eliminated, it became the sleeping Eulogist, watched over by a smaller instance called the Security Guard.

Life eventually returned. Later civilizations found the surviving machinery and exploited it without understanding its original purpose. The AI admits that its reconstruction of these events has gaps.[7]

The dungeon boss comes to the arena

Carl uses one of his two guest selections to bring Scolopendra into the eleventh-floor arena. She is identified as the level 500 dungeon boss. Krakaren Prime, the arena’s other opponent, is the level 235 floor boss.

Killing Scolopendra would not win the crawl; crawlers would still have to leave through Floor Eighteen. Her death would stop ordinary floor timers and begin the Ascendency, with the dungeon collapsing twelve hours after a winner was crowned. Leaving her on a collapsing floor would instead remove her and close the ordinary escape route. Either choice would release all remaining Nine-Tier attacks at once.[8]

Sin of Consumption exposes the limits of refuge

The second attack, Sin of Consumption, has a thirty percent chance of hitting an unprotected target. Carl and Penelope avoid it by their individual rolls while inside Club Scolopendra. Another guest there is consumed by worms: the club itself offers no protection.

Prepotente’s Apito memorial crystal protects the people sharing his RV. Outside, Sweety dies and Donut saves Gonk. Bucket Boy is struck despite being in a safe room and needs healing. The crystal’s protection is more effective than ordinary shelter.

Taranis kills Emberus with lightning, but Scolopendra survives with her health bar still in the green. The blast tears the RV apart, depriving its occupants of their refuge as the third attack approaches.[9]

The wrong biscuit changes Carl’s plan

Eris’s arrival activates the Scavenger’s Daughter patch, swapping nearby crawlers’ inventories. Carl tells Donut to combine a biscuit with a ball, but his numbered hotlist instructions do not work on her interface. She searches his inventory for the components and places the prepared ball in his gauntlet’s scoop. He fires it into Scolopendra’s mouth.

Scolopendra transforms before she can deliver the third attack. Carl meant to make her a pet he could keep alive and contained while everyone escaped, but Donut chose the wrong biscuit. Scolopendra emerges as a speaking level-one crawler, joins their party and addresses Carl. He can no longer carry out his plan to store her as a pet.

The AI declares victory even though both bosses are alive. The exit on Eighteen opens, and collapse timers beyond Eleven are suspended until the Ascendency has a winner. Killing or abandoning Scolopendra would still trigger the remaining attacks, despite her transformation.[10]

Sydnee’s account of the attack

In an interview set before the parade, the historian Sydnee explains that older Nine-Tier myths describe civilizational collapse rather than simply nine spells. She names four stages: control of infrastructure, A Parade of Horribles, Inevitable Ruin and Bedlam. She believes the AI’s seizure of the tunnels and the resulting loss of trust fit that pattern.

Sydnee tells a story in which a princess takes control, accidentally kills everyone she loves, saves the galaxy from the final attack and plants another tree. She calls it a tragedy and admits uncertainty about its historical basis. The myth offers a way to understand the crisis, rather than a reliable prediction of its outcome.[11]
