This arcane device emits waves that disrupt the workings of Shadowtech. These waves can be amplified by any strong antenna, and seem to work even if they're very weak. I theorize that it creates some sort of resonance within the Shadowtech, that slowly builds up and leads to disruption when the damage control kicks in and excess energy is released. It would be possible to adjust our devices to avoid this problem, but to that end, we'd need to know more about how exactly the Disruptor works, and this will require information which is only possessed by those who have employed it.
