Detection

PerDC 14
StlDC 14 (to notice the mechanical instability before use)
InitNone

The saw is a blend of heavy oak and blackened iron. A long, serrated blade vibrates with high frequency in the center of the workspace. A thick leather belt loops from a floor-mounted flywheel up to the rafters, spinning rapidly whenever the foot pedal is depressed. The air smells of friction-heated leather and scorched sawdust.

Standard Engagement

Trigger

The hazard triggers when a creature attempts to use the saw or moves within 5 feet of the exposed leather belts while the machine is running.

Routine

The saw does not have a routine. It acts as a single-instance hazard when triggered, though it remains active until the flywheel stops spinning.

Reset

The machine stops once the pedal is no longer depressed and the flywheel loses momentum after 1 minute.

Belt Snag

If a creature moves within 5 feet of the machine while it is running, they must succeed on a DC 14 Dexterity saving throw or their clothing is caught in the pulley. The creature is Grappled (escape DC 14) and pulled 5 feet toward the machine. If the creature is wearing loose clothing, like robes, they have disadvantage on this save.

Blade Slip

A creature operating the saw must make a DC 14 Intelligence (Arcana) or Dexterity (Sleight of Hand) check to maintain focus and rhythm. On a failure, the blade snaps or jumps, dealing 3d10 slashing damage to the operator.

Maintain Concentration

Operating the saw requires the same mental focus as concentrating on a spell. If the operator takes damage or is distracted, they must succeed on a Constitution saving throw to avoid a Blade Slip.

Description

A towering, pedal-driven cutting station used by students to refine components for wands and heavy vellum scrolls. It features a vertical five foot steel blade and a twelve inch deep throat for wide materials, powered by a complex network of leather belts and wooden pulleys.

Discovery

A DC 14 Wisdom (Perception) check reveals several jagged tears in the floorboards and bloodless nicks on the edge of the workbench. A DC 14 Intelligence (Investigation) check notices that the drive belt is slightly misaligned and prone to whipping outward.

Archival Lore

Engineered by Master Artificer Vane for the Academy of Fine Sigils, this saw was intended to teach students focus as much as craftsmanship. Vane famously said that a student who cannot keep a steady rhythm with their feet while keeping their fingers from the blade will never master the steady flow of a Tier 3 spell.
