Floor 15 Chase Test

Lore & Background

In the Tower's design philosophy, the early floors are deliberately layered to strip away a climber's assumptions. The first three tests reward different strengths—stamina, navigation, combat—so that no single archetype can breeze through all of them. The Chase Test on Floor 15 completes this quartet by introducing a variable that resists planning: a relentless, mechanical pursuit that punishes hesitation and rewards pure, sustained motion. The open expanse of the floor is designed to disorient; without walls to hug or corners to cut, climbers must rely on their own legs and their own will to keep moving.

The White Flower, the Tower's ever-present arbiter, does not judge the Chase Test by who is fastest in absolute terms. Rather, it measures whether a climber can maintain pace under the psychological pressure of being hunted. Many experienced climbers who aced the combat arena on Floor 10 falter here, caught in the trap of overthinking or attempting to outmaneuver a pursuer that simply does not tire. The test is, in a sense, a mirror: it shows the climber whether they can accept a simple, brutal truth—keep running, do not stop—and commit fully to it.

For Baam, the Chase Test carries an additional emotional weight. As a newcomer with no prior Tower experience, he enters the expanse with no map, no expectation, and no idea what the pursuer will do. His approach—instinctive, stubborn, and uncalculated—contrasts sharply with the measured strategies of veteran climbers, and it is precisely this unselfconscious commitment to motion that the Tower seems to reward. The test becomes a small narrative beat where Baam's defining trait, his refusal to quit, is validated by the Tower's own rules.

In Their Own Story

The corridor stretched in every direction, pale and featureless, the floor humming faintly under bare feet. Baam could feel the vibration growing behind him—a low, rhythmic thrum that meant the chaser was close, closer than he wanted. He did not turn to look. Turning, he had learned in the first three tests, was a small luxury that cost you a step, and a step cost you time, and time here was not a resource. It was a debt.

Ahead, the White Flower glowed at the far edge of the expanse, steady and indifferent. Around him, other climbers' footsteps scattered in every direction—some sprinting, some staggering, some already still on the ground. The air tasted of dust and iron. Baam's lungs burned. His legs felt like they belonged to someone else. But the thrum behind him was still coming, patient and mechanical, and that was enough. That was the whole reason to keep going.

He did not look back. He ran.

Floor 15 — The Chase Test

The Chase Test is the fourth and final trial in the Tower's opening gauntlet, taking place on the fifteenth floor after the running test (Floor 2), the maze (Floor 5), and the combat arena (Floor 10). It is the last test before the first major elimination cut, making it a pivotal moment for every new climber.

Rules and conditions: Participants enter a large, open expanse and must reach the White Flower at the far end while being pursued by a relentless chaser entity. There is no combat, no puzzle, no negotiation. The sole requirement is to keep moving and arrive before the pursuer catches you. The floor is deliberately featureless to remove tactical shortcuts—no walls to hide behind, no corners to exploit.

The unique mechanic: The test is purely kinetic and psychological. The chaser does not tire, does not strategize, does not stop. It simply pursues at a constant, inexorable pace. This means the climber's only variable is their own speed and stamina. The twist is that the test punishes overthinking: climbers who try to outmaneuver, loop, or feint often waste energy and fall behind. The simplest strategy—run straight, keep pace, do not stop—is the most effective.

Notable attempts: Baam, as a first-time climber, approaches the test with no prior knowledge and relies on instinct and sheer refusal to quit. His uncalculated, all-in commitment to forward motion contrasts with more experienced climbers who attempt to strategize and sometimes falter. The test passes those who sustain effort and fails those who hesitate or overthink.

Design philosophy: The Chase Test completes the Tower's early quartet by testing a purely physical and mental attribute—endurance under pressure—that the other three tests do not isolate. It reveals the Tower's broader design principle: no single skill set is sufficient. A climber must be fast, clever, strong, and stubborn in equal measure. The open, featureless arena is a deliberate removal of all external aids, forcing the climber to confront their own limits with nothing but their legs and their will.

Did You Know?

• The Chase Test is the final trial before the Tower's first major elimination cut, meaning it is the last chance for a climber to prove they belong before the Tower begins thinning the herd.
• The open, featureless design of Floor 15 is a deliberate contrast to the maze of Floor 5 and the enclosed arena of Floor 10, forcing climbers to rely on internal drive rather than external spatial cues.
• Baam's approach to the Chase Test—pure, uncalculated forward motion—echoes his defining character trait of stubborn, instinctive perseverance, making the test a small narrative validation of who he is.
• The chaser entity in the test is described as tireless and mechanical, suggesting the Tower's tests are not about defeating an opponent but about outlasting a force that will never give up on you.
