Made a char to try this build out, and not only is it really powerful even early on (4 separate sources of healing on a single char at level 1 is insane), it is also very RP-friendly, since the character is well defined by its favoured (Aggressive, Cruel, Clever, Shady) and disfavoured (Diplomatic, Benevolent, Rational or Honest) dispositions.
So not only does playing a bloodthirsty maniac fit, it's a requirement.
Well done OP, well done.
