Detection

PerDC 24
StlDC 24 (trained)
InitNone (simple hazard)

“Translucent violet quartz spires, each standing six feet tall and glowing with a faint, internal rhythmic light that pulses like a heartbeat.”

Standard Engagement

Trigger

A creature moves within 15 feet of any of the three pylons.

Routine

None

Reset

The pylons require 1 hour to re-attune their vibrations before they can trigger again.

Shattering Chord

The pylons emit a piercing chime in a 20-foot burst centered in the middle of the pylon triangle. All creatures in the area must attempt a DC 24 Fortitude save. On a Critical Success, the creature is unaffected. On a Success, the creature takes 2d10+5 sonic damage. On a Failure, the creature takes 4d10+10 sonic damage and is deafened for 1 minute. On a Critical Failure, the creature takes 8d10+20 sonic damage and is permanently deafened.

Sympathetic Resonance

If a creature is carrying a glass or crystal object when the Shattering Chord triggers, that object must succeed at a DC 24 Fortitude save or be broken.

Description

Three jagged amethyst pillars arranged in a triangle vibrate with a low-frequency hum that intensifies as living matter draws near, eventually releasing a destructive sonic blast.

Discovery

DC 24 Perception (trained) to notice the geometric patterns of dust vibrating on the floor or DC 26 Arcana (trained) to detect the buildup of resonant magical energy.

Archival Lore

“The resonance pylons were originally developed by the resonance mages of the Crystal City to deter tomb robbers without damaging the precious scrolls kept within, as sound does not burn or corrode.”
