Where do I get the HP?

There's a feat or class that allows you to ad your charisma to AC? Does anyone know more about this?

I think the Mystic Wanderer from Magic of Faerûn lets you add Cha to AC, but only if you're unarmored. Or something like that, it's been a while since I checked.

Which means that a monk/duelist/mystic wanderer (would need some other classes too, since IIRC Mystic wanderer requires some cleric spellcasting) could add all three of his mental stats to AC, in addition to Dex. Though the MW might require chaotic alignment, which would make it troublesome to combine with monk.

I thought there was a class or feat that let you add CHA to your AC as a dodge bonus while wielding a finessable weapon. Might have been a 3.0 thing from Sword and Fist though.

I believe that was from the 3e Prestige Class on Wizards.com called the Arcane Duelist. They got their Charisma bonus to AC, among other things.
