After rolling Casting dice for a Gut Magic spell, a Butcher with the Sickle may choose to cause a wound on a unit he has joined in order to gain another Casting dice, which may exceed his normal limit. This extra dice is rolled immediately and added to the casting total. This may cause Irresistible Force or a Miscast as usual, and may only be done once per phase. Wounds caused by the Sickle may not be allocated to characters, and may not be saved or Regenerated in any way.
