Help Index :: :: After many years of experience, thieves and other scoundrels learn to take advantage of all the situations that arise during a fight, especially opportunities made by other members of their own party. One who is skilled at dirty fighting knows how to leap on these opportunities and deliver a quick but powerful blow as a comrade performs a takedown on an opponent or otherwise makes the victim temporarily vulnerable. Opportunistic strikes on prone foes give thieves a chance to really put their muscle behind their blow. This skill is automatic in combat.
