For the record, I recently changed the following class features (again) so that they now explicitly depend upon less powerful abilities, so as to better define what powers can be acquired by the Class Feature class feature (which is not only fun to say, but has become just as problematic an ability):
  • Pugilist: Slowga (based on Slow), Hastega (based on Haste)
  • Ronin: Sentinel (based on Guard)
  • Blitzer: Dark Buster (based on Dark Attack), Silence Buster (based on Silence Attack), Sleep Buster (based on Sleep Attack), Triple Foul (based on Dark Attack, Silence Attack & Sleep Attack)
