So here's a random thing I'm trying to do: create a build that winds up with no base classes. I think I did this a while ago back on 339 but my search-fu is weak.
Here's my stab at it so far, using paladin and a weird trick stacking shadowbane inquisitor so that I get a "virtual" paladin 11 which lets me trade the levels away with no leftover.
Paladin 5/Dark Hunter 3/Shadowbane Inquisitor 10... from here take two blackguard and trade in all your paladin levels
result: Blackguard 7/Dark Hunter 3/Shadowbane Inquisitor 10
- full BAB, Cha to saves, sneak 7d6, 4th level blackguard spells, 9 smites/day, fiendish servant and undead companion, debuffing despair, etc.
- you retain your Shadowbane Inquisitor abilities, and those levels count as fallen paladin for extra blackguard abilities
- Dark Hunter was to get sneak attack... can anyone else find a class that grants sneak attack that a paladin can easily qualify for? this one burns a lot of skill points and feats
edit: and yes I am aware of the Defiant from Planar Handbook. That's too easy.
