Or your Vampire or Lich royal, if you chose one for a pretender, or a Vampire Count from Sanguine Heritage, or Etimmu if you're the Ashen Empire.

If you're R'lyeh, get those Void Spectres out and about, and drive enemy pretenders insane. It's permanent, and you can drive up their insanity score to 100... and IIRC they're something like Stealth +20, giving them some time before they get caught.
