Resonance Crystals

Created by Kstarfireheart3583

This elegant wooden case lined with deep velvet contains eight palm-sized crystals of exceptional clarity, their interiors shot through with veins of amethyst purple and peridot green. When a creature hums or plays a specific musical frequency in proximity to the crystals, they begin to resonate with a subtle, otherworldly vibration imperceptible to most mortal ears. The crystals emit a subsonic sound that reverberates through the mystic plane, creating profound discord within the essence of paranormal entities. Any ghost, specter, vampire, or similar undead creature within 30 feet of the activated crystals must make a Constitution saving throw or suffer disadvantage on all attack rolls and saving throws for 1 minute. The effect persists as long as the crystals continue to resonate, though maintaining the frequency requires concentration as if casting a spell. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself with a success. The crystals require a short rest between uses to fully recharge their resonant properties. Scholars believe these items were crafted by ancient artificers who sought to protect the living world from spectral incursions and otherworldly hauntings.

Effects

Resonant Discomfort

When activated by humming or playing a specific frequency, any ghost, specter, wraith, or similar incorporeal creature within 30 feet must make a Constitution saving throw (DC 15). On a failure, they suffer a -4 penalty on all attack rolls and saving throws for 1 minute. The effect persists as long as the frequency is maintained, requiring concentration. A creature can repeat the saving throw at the end of each of its turns to end the effect on itself. The crystals require a short rest to recharge between uses.
