I'm thinking of taking a Purple Dragon Knight and leveling him as Sacred Fist (the "handwrap paladin" archetype).

Since PDK can use CHA for Attack and Damage, there might be some good synergies. And if it turns out I don't like playing a paladin in robes with handwraps -- well, his fighter splash has given him armor, martial weapons, and tower shield proficiencies.

Whaddya think?
