Jack urinates on the dungeon wall before anyone can stop him. Donut lunges and pulls back, while Yolanda shoots Jack in the head, but the damage is already done: the stain smokes and summons a massive level 93 Rage Elemental. Randall falls from the accelerating wheelchair train, and the elemental forms near Jack's body as Yolanda's arrows shatter harmlessly against it.

The system description reveals the Rage Elemental is nearly indestructible, self-healing, and said to dissipate only after claiming 666 souls. Carl orders Donut to use Confusing Fog, but the creature pushes through the fog, shreds Jack's corpse, and tears through Yolanda and Randall. Carl pauses to remember Yolanda's kindness and lifelong dedication before acknowledging that Yolanda dies heroically while trying to protect others.

Carl activates Protective Shell at the last second, and the elemental rebounds when its claws hit the force field. The brief protection gives Carl, Donut, Imani, Chris, Brandon, and the surviving residents a chance to reach the safe room, though the cars are too wide for the entrance and the rescuers must physically pull people from their chairs.

The elemental casts a gravity-reversal spell that sends Carl, Donut, the last train car, and Mrs. McGibbons crashing onto the ceiling. Carl grabs the badly injured Mrs. McGibbons, gives her a healing potion, and carries her toward the door. After falling back through the edge of the spell, Carl protects her body, heals himself, and runs as the elemental charges behind him.

Carl dives into the safe room just ahead of the elemental's claws, hands Mrs. McGibbons to Brandon, then tosses a lit boom jug at the monster before slamming the door. Inside the safe room, revealed to be a dingy Big Shot Chicken restaurant, survivors cry, heal, and mourn Yolanda and Randall while the Rage Elemental screams and pounds against the impenetrable door outside.
