Detection

PerDC 28
StlDC 28 (or 0 if the pillar is actively ticking loudly)
InitNone

“The hazard appears as a ten foot tall ornate pillar made of polished brass and stained glass. Four clock faces at the top spin at erratic speeds, and the sound of frantic, metal-on-metal grinding echoes from within its base.”

Standard Engagement

Trigger

A creature moves within 10 feet of the pillar or touches it.

Routine

None

Reset

The pillar must be manually rewound and the internal springs replaced by a master smith, taking 1 hour.

Harmonic Backlash

The pillar releases a thunderous, dissonant chime in a 20 foot burst. All creatures in the area take 6d12+10 sonic damage. A DC 28 Fortitude save determines the result. Critical Success: The creature is unaffected. Success: The creature takes half damage. Failure: The creature takes full damage and is Deafened for 1 minute. Critical Failure: The creature takes double damage and is Stunned 1.

Resonant Vibration

Any creature wearing heavy metal armor or carrying a metal shield takes a -2 penalty to their Fortitude save against the Harmonic Backlash effect as the vibrations travel through their gear.

Description

A malfunctioning decorative clock tower in a busy metropolitan plaza that has begun to build up massive amounts of kinetic energy, releasing it as a devastating harmonic pulse.

Discovery

A character who succeeds at a DC 28 Perception check notices the pavement around the pillar is vibrating rhythmically, or a DC 26 Crafting check identifies that the clock's escapement mechanism is dangerously close to a catastrophic failure.

Archival Lore

“Originally commissioned by the city's Guild of Horologists to synchronize time across the district, this specific pillar was sabotaged or suffered a critical gear-slip that turned its chime into a lethal weapon.”
