Hrrrrrrrm. I'm going to be weird this time, and so I shall ask you all what you'd prefer me to make.
Your two options are:

  • A Healer/Dread Necromancer PrC Plague Doctor, with a dissolved oath (because oaths are for wimps) and the ability to both cure and propagate diseases, as well as the ability to give his friends beneficial symbiotic "diseases" that heal and enhance rather than harm.
  • A Marshal/Hexblade PrC that functions like a WH40K Commissar, simultaneously buffing his allies and debuffing his enemies with a Bardic Music/Screamed Threats type effect, only running on Intimidate checks (or Curse uses) instead of Perform checks.
