Force (X) "A Weapon with this Special Rule may double a Characteristic with a Willpower Check, but may suffer Perils of the Warp."
When selected to be used as part of a Combat or Shooting Attack, a Willpower Check may be made for the Model that will use this Weapon to make attacks. If it is successful then the Characteristic listed as X is doubled (if that Characteristic is AP, then the AP is instead changed to AP 2). If a double is rolled when making this Willpower Check then the Model using the Weapon to make attacks suffers Perils of the Warp.
