Detection

PerDC 22
StlDC 21
InitN/A

“Clusters of fist-sized, translucent violet crystals that pulse with a faint, rhythmic internal light. The air around them feels oddly still and heavy.”

Standard Engagement

Trigger

A creature enters a 10 foot radius around the crystals or creates a loud noise (such as a sonic spell or a shout) within 30 feet.

Routine

None

Reset

The crystals require 24 hours of geological silence to regrow and stabilize before they can trigger again.

Harmonic Shatter

The geode explodes in a cacophony of sound. All creatures in a 15 foot emanation must attempt a DC 21 Fortitude save. Critical Success: The creature is unaffected. Success: The creature takes 2d8 sonic damage. Failure: The creature takes 4d8 sonic damage and is deafened for 1 minute. Critical Failure: The creature takes 8d8 sonic damage and is deafened for 1 hour.

Dampened Resonance

Casting a 2nd level or higher Silence spell on the area of the crystals renders the hazard unable to trigger for the duration of the spell.

Description

A cluster of pale lavender crystals growing from a jagged fissure in the cavern floor. These crystals are hypersensitive to kinetic vibrations and elemental shifts in the earth.

Discovery

DC 22 Perception to notice the crystals vibrating in harmony with the heartbeat of nearby creatures or DC 20 Nature to identify the geode as a source of unstable elemental energy.

Archival Lore

“Found primarily in deep caverns where the Plane of Earth bleeds into the Material Plane, these crystals act as natural barometers for tectonic pressure, often releasing stored energy when disturbed by surface-dwellers.”
