REAPER

An incredibly vile nanovirus, reaper is used in both torture and espionage. It has a single purpose—to inflict excruciating pain and damage to the subject. It floats inert in the bloodstream until activated, at which point the nanites burrow outward in random directions.  Unlike other nano-weapons reaper can be activated up to 5 times and each time the results are more intense than the previous activation.

When reaper is activated, the subject is inflicted agonizing pain that imposes a –2 penalty to ability checks, attack rolls, and skill checks.  In addition, the subject must make a CON DC 20, or take 1d8 points of damage.  This damage is not subject to any form of shielding or damage reduction.  Each time reaper is activated the damage increases by 1d8, so by the fifth activation it does 5d8 damage.  Each activation is subject to a separate Fortitude saving throw.  In the case of a successful saving throw the subject only takes half damage for that activation.  Reaper can only be activated once per round, but does not have to be activated in successive rounds.

Reaper comes with a small remote control for activating the nanites.  The range on the remote control is limited to 500 feet.  Since reaper is used in espionage it was specifically designed not to work on wireless Cortex or Tracer frequencies as to avoid any form of remote detection from traffic sniffing.
