Glitch Whistle

This innocuous-looking whistle emits a frequency inaudible to the human ear, though birds and other creatures with keen hearing may react with agitation or distress when sounded. When activated, all electrical devices and magical constructs within 60 feet begin to malfunction and spark erratically, their systems overwhelmed by the whistle's disruptive resonance. The effect persists only while the whistle is being blown; once you cease, devices gradually stabilize over the course of a few rounds. The primary risk of discovery lies not with humanoid observers, but with any nearby birds or beasts sensitive to the high-pitched tone, who may react with unusual aggression or panic that could draw unwanted attention. This whistle is often ingeniously concealed within other objects—disguised as the cap of a writing instrument, hidden within a walking cane, or integrated into the hilt of a blade or firearm. Some specimens have even been crafted into jewelry such as rings or pendants, allowing for discreet deployment in sensitive situations.
