Wikipedia wrote:The Molecular Disruption Device is a fictional weapon of mass destruction featured in the Ender's Game series of science fiction novels by Orson Scott Card. Given the awkwardness of saying "molecular disruption device" or "molecular detachment device," the name was abbreviated to "M. D. Device," which gave rise to the nicknames "Dr. Device" and "The Little Doctor" as a joke. Originating from Formic technology it sets up a field in which the covalent and ionic atomic bonding cannot exist. The field's strength weakens with distance, but is regenerated when it encounters another molecule. This chain reaction rips apart molecules and can be used to destroy ships, fleets (when ships are in close proximity) or even an entire planet.
The radius of each explosion would be equivalent to the size of the object being destroyed, multiplied by 2. Therefore, if a minifig is being destroyed, anything within 2 inches of it would also disintegrate. Could be used instead of a nuke as an game-end mechanic, because it is possible it would actually leave survivors.
Edit: Apparently we're going to use d12 Electric rules for this now.
