Force Any Psyker with a weapon or ability with this special rule may choose to make a Psychic check before making any attacks with that weapon or resolving the ability. If the Check is successful then the Strength value of any attacks made is doubled. If the Check is failed then Perils of the Warp is resolved targeting the unit containing the model that failed its Check. If the Psyker survives Perils of the Warp then it may attack as normal.
Deflagrate After normal attacks by this weapon have been resolved, count the number of unsaved Wounds caused on the target unit. Immediately resolve a number of additional automatic Hits on the same unit using the weapon’s profile equal to the number of unsaved Wounds – these can then be saved normally. Models in the targeted unit must still be in range in order for these additional Hits to take effect. These additional Hits do not themselves inflict more Hits and do not benefit from any other special rules possessed by the attacking model, such as Preferred Enemy (X) or Precision Strikes (X).
