KILLSWITCH

Killswitch is a deadly nanovirus used by extremist governments and top-secret agencies to blackmail subjects into doing something they normally wouldn’t do. Killswitch isn’t just a clever name, it allows someone to trigger a potentially deadly nanite attack remotely as simply as flipping a switch.  Unlike other nanoviruses, killswitch isn’t always injected, but often ingested after being planted in food or drink. After ingestion, the killswitch nanites work their way to the brain and heart of the subject. Killswitch must be triggered, but may be done so remotely through the Cortex or the Tracer network. These nanites can also be set to trigger if the subject ever disconnects from the Cortex or the Tracer network. 

When kill switch is triggered, the subject must make a CON save (DC 25) or take 4d6 Constitution damage.  If the subject makes their saving throw they take half damage.
