The Brass Maw Grinder
A sixty foot long corridor where the floor is composed of massive, interlocking brass gears that rotate at varying speeds. The walls are lined with vertical bronze pistons that slam outward, forcing trespassers into the rotating floor mechanisms.

Defenses
Detection
“Polished brass surfaces dominate the hallway. Gaps between floor plates reveal a deep pit filled with grinding cogs. The air smells of hot grease and ozone.”
Standard Engagement
The hazard activates when a creature of Small size or larger steps onto the third floor gear from the entrance.
On initiative count 20, the floor gears spin rapidly, and the wall pistons strike. Each creature in the hallway must make a DC 15 Dexterity saving throw. On a failure, a creature takes 11 (2d10) bludgeoning damage and is knocked prone. On a success, they take half damage and are not knocked prone. On initiative count 10, any creature prone on the floor is pulled 10 feet toward the center of the room by the rotating gears and takes 7 (2d6) slashing damage from the interlocking teeth.
The trap automatically resets after 1 minute of inactivity.
Prone creatures are subjected to grinding teeth that ignore half-cover.
Wall pistons attempt to push targets into the most dangerous gear intersections.
The floor is coated in machine oil. Creatures moving through the hallway must treat it as difficult terrain unless they have a climb speed or specialized footwear.
