Swashbuckee

Whereas many warriors brave battle encased in suits of armor and wielding large and powerful weapons, swashbucklers rely on speed, agility, and panache. Swashbucklers dart in and out of the fray, wearing down opponents with lunges and feints, all while foiling the powerful attacks against them with a flick of the wrist and a flash of the blade. Their deft parries and fatal ripostes are carnage elevated to an art form. Some may be arrogant and devil-may-care, but behind this veneer lie people deeply dedicated to their craft. Those of smaller races are particularly driven to prove that the right mix of discipline and daring is the perfect counter to size and strength, and enjoy nothing more than taking down lumbering brutes and bullies.
