This is one of the bronzed locusts from a plaque of locusts (an unlikely entomological phenomenon generally attributed to the high level of background magical radiation in deserts). Even though it's been separated from its magically animated plaque, it practically hums with mystical energy.
You hold up the bronze locust. It glows brightly, and a swarm of locust descends on your enemy, picking its bones clean. Even if it wasn't obvious that it had bones.
