Detection

PerThe whistling of steam and the rattling of chains makes its state obvious to anyone within 30 feet, though identifying the specific failure requires a check.
StlDC 21 (or DC 12 if the saw is already running and audibly malfunctioning)
Initnull

The blade is pitted with age but kept razor-sharp. A thick lattice of pulleys and rusted chains connects the central axle to a nearby steam manifold. Vents intermittently hiss with white vapor, and the entire floor vibrates with the saw's speed.

Standard Engagement

Trigger

A creature attempts to use the saw to cut a log or interacts with the pulley system while the steam manifold is stuck.

Routine

null

Reset

The hazard resets after 1 hour once the steam manifold cools and the pressure is manually bled from the system.

High-Velocity Kickback

The saw catches on the wood and lurches forward while chains whip outward. The saw makes a strike against the triggering creature and all creatures within a 5-foot burst. Strike: +15 Melee (slashing), Damage: 2d12+10 slashing damage. On a critical hit, the target is also knocked prone by the force of the shattering wood slabs.

Entangling Pulleys

Creatures adjacent to the saw must succeed at a DC 21 Reflex save or have their clothing or limbs caught in the whirling chains, becoming Grabbed (Escape DC 21) until they spend an Interact action to free themselves or the hazard is disabled.

Unstable Momentum

If the saw takes cold damage, the DC to disable it with Thievery or Athletics is reduced by 2 for one round as the metal contracts and the steam pressure drops.

Description

A massive, 5-foot diameter serrated circular saw mounted on a heavy iron rail. It is powered by a network of hissing brass pipes and rattling grease-stained chains. When the steam heat gets stuck, the blade spins at a blurring, lethal velocity.

Discovery

Perception DC 21 or Crafting DC 19 to notice the rhythmic, high-pitched thumping of an imbalanced boiler valve indicating imminent pressure failure.

Archival Lore

Originally designed for the College of Engineering's shipyard, this saw was moved to the general workshop after a minor explosion. Students refer to it as 'The Shredder' because of its tendency to lock into high-speed cycles.
