NANO-EMP

The nano-EMP is one of the great equalizers when primitive societies find themselves at odds with highly advanced ones.  These nanites are often gifted to primitives by spacefaring societies who are opposed to the advanced society the primitives have found themselves at odds with.  After injection, the nano-EMP lays dormant in its host.  The host can activate the nano-EMP as a move action.  Once activated the nano-EMP lets out a relatively weak 30-foot radius electromagnetic pulse.  This pulse is too weak to destroy electronic equipment but is strong enough to prevent it from functioning while in its area of effect.  The pulse effect last for 4d6 rounds and cannot be turned off once activated.  This nano-weapon is a one-use item.  Cybernetics and bionics (biotech) operate on biological systems and are not affected by this nano-weapon, but the pulse does temporarily shut down other nanites.
