A true terror of the skies, the Flying Buttress has put an end to many adventurers. They have a silent but deadly attack and often form the rear guard in elite squads of crack troops. Well known for their cheeky personalities and can-do attitudes, the Flying Buttress presents a stern challenge to any traveller. Their appearance is a total bummer.
