I was planning an Antropomorphic Badger Dragonfire Adept/Dread Pirate.

DFA has Intimidate and Appraise as class skills.

With Beguiling Influence+Entangling Exhalation+Slow Breath+Frightful Presence Invocation, and the Badger's Rage+Intimidating Rage+Imperious Command.

The problems were LA+3, and I couldn't find a satisfactory method of dealing damage to myself as a free action. Blood Magus was the best I found, but it didn't synergize well with Dragonfire Adept.
