Darth Vader should had lost his paladin levels and become a fighter/BG according to 3rd edition rules. According to d20 Star Wars rules, as of Episode IV, Darth Vader's build was Fringer 1/Jedi Guardian 11/Sith Lord 6. Bah, got me. Never read the d20 SW rulebook. Reminds me of the PRC too much, eh?...
