What is defensive duelist 5e?

Defensive Duelist is a Feat available in Dungeons and Dragons 5th edition that allows a character to use their finesse weapon to parry an incoming attack, adding their proficiency bonus to their AC if successful. This feat is particularly useful for characters who rely on quick movement and deceptiveness in combat rather than brute strength. It requires a Dexterity score of 13 or higher to take. The feat can be used once per turn, and the character must be wielding a finesse weapon and have it ready for use. Defensive Duelist is a powerful tool for avoiding damage in combat and should be considered by any character who excels in quick, agile fighting styles.
