Grinding Gearway - AI-generated fantasy Hazard

Grinding Gearway

A 10-foot section of the floor consists of interlocking brass plates that look like part of a massive, horizontal gear system. When weight is applied, the floor plates rotate rapidly in opposite directions, attempting to crush and grind anything caught between the seams.

Detection

Per15
StlDC 15 (Perception)
InitN/A

Polished bronze floor tiles arranged in concentric circles. Faint lines of dark, viscous grease can be seen seeping from the thin gaps between the plates.

Standard Engagement

Trigger

The hazard triggers when a creature weighing 20 pounds or more steps onto any part of the 10-foot gear section.

Routine

N/A

Reset

The gears automatically reset after 1 minute, clicking back into their original static position once weight is removed.

Crushing Rotation

When triggered, creatures on the floor must make a DC 14 Dexterity saving throw. On a failure, they take 22 (4d10) bludgeoning damage and are Grappled (escape DC 14). On a success, they take half damage and are not grappled as they leap to the nearest safe space.

Entrapped Limb

While a creature is Grappled by the gears, any further movement of the mechanism (such as if a second plate is triggered) causes an additional 11 (2d10) piercing damage as the internal teeth bite deeper.

Description

A 10-foot section of the floor consists of interlocking brass plates that look like part of a massive, horizontal gear system. When weight is applied, the floor plates rotate rapidly in opposite directions, attempting to crush and grind anything caught between the seams.

Discovery

A DC 15 Wisdom (Perception) check reveals the faint, rhythmic ticking of clockwork beneath the floor and the sharp scent of metallic oil. A DC 15 Intelligence (Investigation) check identifies the floor plates as mobile gears designed to spin inward.

Archival Lore

Built by the obsessive gear-smith Krivaldi, these floor traps were designed to filter out clumsy intruders. They serve as both security and a rhythmic metronome for the mechanical guardians that patrolled his laboratory.
