So, can anyone post nice swashbuckler builds? I really like to see one but haven´t got the books. It doesent have to be the best optimal. Maybe you can post 2 or 3 different builds with diferent flavor.
Human rogue 1, weapon proficiency rapier, light shield proficiency.
Done.
Perhaps you could talk to your DM about allowing a cloak wrapped around the arm to count as a shield as well, if you fancied that kind of a look. Anything that could conceivably grant +1 AC would be fine in my opinion.
It's also not to far of a stretch to ask your DM to count "rapier in one hand, nothing in the other" as "wielding two weapons" for the ranger powers that require it.
