The Duelist

From publisher blurb:

Duelists represent the pinnacle of elegant swordplay. They move with a grace unmatched by most foes, parrying blows and countering attacks with swift thrusts of their blades. They eschew bulky armor as their grace allows them to dodge their opponents with ease. While others flounder on treacherous terrain, duelists charge nimbly across the battlefield. They thrive in melee, where their skill with the blade allows them to make sudden attacks against clumsy foes and to cripple opponents with particularly well-placed thrusts of the blade.

Prestige Class: Duelist.
Build Classes: Fighter.
