Crusty Salt Crystal

This rough, crystalline formation appears to be both salt-encrusted and strangely alive, teeming with a low, chirping hum. When held, the Crusty Salt Crystal grants the user advantage on Wisdom (Perception) checks made to locate creatures or objects within 60 feet that are obscured or hidden. However, in exchange, the wielder must make a DC 10 Constitution saving throw at the end of each long rest; on a failure, they gain one level of exhaustion as they suffer from persistent dryness in their throat and skin, reminiscent of the salty depths where Salt-Glazed dwells. The crystal remains a constant reminder of the briny abyss, emitting a slight, disquieting vibration.
